LEADERSHIP FOR CONTRACTOR MANAGEMENT Angus Macinnis, Special Counsel, Occupational Health, Safety and Security Group, Norton Rose Australia

By now, all principals should be aware of the requirement in section 46 of the Work Health and Safety Act 2011 for parties with concurrent safety duties to consult, cooperate, and coordinate activities. How does that obligation affect what it means to be a leader when it comes to the safety aspects of contractor management?

4 SAFETY SOLUTIONS - DECEMBER 2012/JANUARY 2013

www.SafetySolutions.net.au

O

n one view, it might be thought that the new legislative obligation makes leadership on safety less important than it once was.

If contractors are now obliged by law to engage with the principal, and with other parties, it might be thought that there is no longer any need for the principal to take a leading role in the process.

The truth, however, is that leadership is more important than ever. The consultation obligations in the WHS Act enshrine the importance of leadership and, in particular, the best form of leadership - leadership by example. A principal which has its own safety obligations in order will be better able to identify what its contractors know, and don’t know, about the safety obligations which arise from the contractors’ work. Once any gaps in knowledge are identified and filled, a principal which has its own house in order will also be able to encourage continuing compliance by the example of its own compliance.

Equally, although safety leadership by a principal is not a certain guarantee that contractors will follow that lead, it is all but certain that a want of leadership from a principal will result in safety failings on a project. The principal’s interest should extend beyond its own safety obligations because quite apart from the fact that the failure of leadership may see the principal prosecuted, stoppages of work (and injuries to the principal’s employees) can occur as a result of failings further down the contractual line.

So what are prudent principals doing in order to show safety leadership in managing contractors? Here are some of the practical steps which you can consider.

Start at the very beginning (or even before) Before a principal has contractors to manage, there has to be a decision on the part of the principal as to who it is that the principal wishes to engage to do the work. Sometimes this decision will

be the result of a formal tender process; in other cases, it might be the result of nothing more formal than a telephone conversation or an exchange of emails.

However, regardless of how formal or informal the process is, the purpose should be the same - to obtain the information necessary to enable the principal to decide whether this contractor is the one the principal wishes to engage. At the most basic level, the principal will want to know things like whether the contractor has the necessary skills and how much the contractor is going to charge.

In this process, the principal should also gather information about the contractor’s understanding of the contractor’s safety obligations and what the contractor does to comply with them.

Just as the basis for the collection of financial information can be formal or informal, so can the collection of safety information. In a tender for a large contract, it will be quite common to have a detailed questionnaire, and to ask the prospective tenderer to provide copies of documents which evidence their safety systems. (It shouldn’t be thought that such requirements are confined to tenders in high-hazard industries such as mining or construction - law firms are increasingly being asked to provide information about their work health and safety systems when they tender for work.) For smaller contracts, simpler requirements may be imposed, but it is always a good idea to get an understanding of what the contractor knows about safety before making the decision to engage them.

The safety information should then form part of the decision-making process in relation to the engagement of contractors.

Of course, the fact that a contractor does not have a good understanding of safety obligations may not automatically rule that contractor out of contention, but it may mean that the principal will need to pay particular attention to the work of such a contractor to ensure that naïveté does not translate to non-compliance.

CONTRACTOR MANAGEMENT

JUST AS THE BASIS FOR THE COLLECTION OF FINANCIAL INFORMATION CAN BE FORMAL OR INFORMAL, SO CAN THE COLLECTION OF SAFETY INFORMATION. IN A TENDER FOR A LARGE CONTRACT, IT WILL BE QUITE COMMON TO HAVE A DETAILED QUESTIONNAIRE, AND TO ASK THE PROSPECTIVE TENDERER TO PROVIDE COPIES OF DOCUMENTS WHICH EVIDENCE THEIR SAFETY SYSTEMS ...

their respective obligations, and reduced the result of those discussions to formal contractual language, will be very useful evidence by which the principal can show that it has taken the leading role in doing all the things that it was reasonably practicable for the principal to do.

What if the principal does not have all the answers?

Get it in writing Once the contractor has been selected, it’s time to get down to the process of documenting the agreement to get the work done. It’s always a good idea to include some provisions dealing with the respective safety obligations of the parties beyond the generic “each party should comply with all relevant laws”. These provisions do not need to be lengthy, but they should provide some content to the duty to consult, and should ideally identify any particular issues arising out of the contract work (for example, in a contract for the design of registrable plant, the particular obligations of designers under Part 5.2 of the WHS Regulation).

There are at least three good reasons why the contract should include provisions dealing with safety matters. The first is that it establishes, from the outset, the principal’s expectations in relation to safety. The second is that if concerns about safety arise during the performance of the contract, the words used and agreed at the outset provide a useful objective reminder of what the contractor has signed up to do. The third, and arguably most important reason, relates to the discharge by the principal of its obligation to ensure safety “as far as is reasonably

practicable”, where the question is likely to be, “Did the principal do all that was reasonably necessary to ensure safety compliance by the contractor?”

It is conceivable that there will be some situations (albeit very few) in which the obligation of reasonable practicability will be discharged by simply engaging competent contractors and letting them get on with it. In most cases, however, more than this will be required, because it will be reasonably practicable for the principal to supervise the work of contractors to some extent. An express contractual provision enables the principal to show that the principal has turned its mind to this question.The principal should consider both the extent of supervision and how that supervision will work in practice. It will be a rare case in which the principal will be required, in order to discharge its obligations, to minutely scrutinise all “safety homework” done by the contractor - however, the principal may well need to establish some basis for assuring itself that the contractor’s homework is actually being done.

Of course, the principal cannot contract out of any safety obligations that the principal has, but evidence that principal and contractor have discussed and considered

6 SAFETY SOLUTIONS - DECEMBER 2012/JANUARY 2013

Finally, leaders should also be listeners, and safety leadership means recognising that there will be situations in which the principal can learn from the contractor.

Although the assumption will usually be that the principal is the most knowledgeable and competent when it comes to safety, this may not always be the case, and if the principal does not attend to its obligations, those failings may affect the contractor.

This is illustrated by a recent New Zealand prosecution. A contractor hired mine machinery to a principal on the basis that the principal was obliged to maintain the machinery. The principal failed to perform the maintenance and, in so doing, exposed the contractor’s employees to a risk to their health and safety. The contractor pleaded guilty to charges which alleged that the contractor had failed to do all that was reasonably practicable to keep its employees safe.

As the contractor accepted, even though the contractor was not obliged to maintain the machinery, it could have turned the machinery off until the maintenance was done. This emphasises that a process of consultation, cooperation and coordination will not work if the principal treats the process as a one-way street.

Conclusion Safety leadership should always be one of the key aspects of being a leader of industry; and although it is one thing to aspire to safety leadership, it is another thing to put that aspiration into practice.

The key lesson, however, is that safety leadership is best achieved when it is treated as being an integral part of getting the job done, so that the safety performance of contractors is considered at the same time as their financial performance, and the safety clauses of the contract are considered at the same time as the clauses dealing with payment and performance. When it comes to the contracting process, leaders see the safety aspects as built-ins, not add-ons.

Handrails and guardrails ensure safety for Australian miners Whether in the remote areas of Western Australia and Northern Territory, or the newly developing mining regions of Queensland, New South Wales and South Australia, Moddex Systems can supply safety handrails and guardrails.

The company has been working with many of A u s t ra l i a ’s m i n e rs a n d contractors, specifying and supplying its Tuffrail handrails and guardrails for all mining disciplines and accommodation facilities, ensuring the safety of hundreds of site workers and guaranteeing operational productivity.

Mine site installation of conventional handrails and guardrails requires hot work permits, and safety precautions such as barricades and fire spotters, and at times shutdowns necessitating specialist trades eg, welders and boilermakers.

The Moddex Group is registered to ISO 9001 and the installation process of its handrails and guardrails requires no specialist skills nor on-site welding. The drawbacks of hazardous toxic fumes and unsightly cold galvanising and painting

touch-ups are avoided, coupled with reductions in direct costs and overheads.

Independently accredited to Australian Standard AS 1657 stringent load testing criteria, t h e h a n d ra i l a n d g u a rd ra i l tubing and clamp-type fittings are supplied hot-dip galvanised as standard, with wet spray painting or powder coating as options. The integrity of this corrosion protection and surface treatment is maintained due to the avoidance of site welding.

The safety handrail and guardrail heavy-duty tubular steel and cast iron fittings construction provide full compatibility with the tough and demanding environments of Australian mine sites. The modular design can suit diverse layouts and applications, from safety barrier protection at ‘no go’ zone and plant areas, rail track culverts and water reservoirs, to equipment lay-down and storage yards, workforce accommodation and catering facilities etc.

Fog maker Idrotech’s Elefante fog maker can be used to combat dust problems at mine sites.

The fog maker works by shooting a strong, continuous plume of fine mist or fog up to 60 m long. Because the fog particles are similar in dimension to the dust particles, they combine easily with one another and, aided by gravity, fall to the ground. It is suitable in open cut mining environments and building and road construction sites where dust is a significant problem.

The fine mist spray is propelled by a fan, upon which three concentric nozzle rings are mounted. A wide range of nozzles of different capacities can be fitted to the rings, providing the right water volume to suit the situation or environmental condition.

The mist droplets generated are fine and they evaporate quickly, which avoids problems associated with water pooling or runoff.

HEARING PPE

ADVANCES IN FIT TEST TECHNOLOGY FOR HEARING PROTECTORS

I

Terry Gorman, Senior Occupational Hygienist, 3M Occupational Health & Environmental Safety Division

t has been shown that hearing protectors can provide a suitable level of protection to workers exposed to noise.

However, to get appropriate performance from these devices, there are several elements that need to be addressed.

These elements are: • Attenuation - what level of noise reduction is needed?

• Fit - is the product fitted correctly?

• Comfort - the product must be comfortable or it will not be worn!

• Compatibility - there may be other PPE (eg, safety eyewear, respirator) that also needs to be worn without degrading the protection level.

• Wear and tear - the product should be regularly inspected and maintained or replaced when degraded.

Australian Standard AS/NZS 1269.3 gives detailed guidance on these aspects. However, recent developments in technology have given us another way to view the attenuation and fit elements.

Currently, hearing protectors are tested for attenuation to AS/NZS 1270 by using a panel of 16-20 test subjects with normal hearing.

Each subject is exposed to sound at various frequencies and volumes to determine their threshold of hearing and then retested - this time with the hearing protector in place.

The difference between these signals (protected and unprotected) is the attenuation of the product. These results for the whole panel are then averaged to give an attenuation value called the SLC80.

This averaging step means some test subjects achieved a higher attenuation than the published SLC80 value, but some received a lower attenuation. In practice, this means a proportion

www.SafetySolutions.net.au

of users will get lower attenuation than the published SLC80 rating and are therefore at risk of overexposure to noise.

This is not surprising - like shoes, we cannot expect one type/size of protector to perfectly fit everyone. Variations in the size and shape of the individual’s ear canal mean that some types and sizes of earplugs will not seal effectively and should not be used.

Recent advances in design and capability of miniature microphones and electronics now allow us to measure the attenuation given by a particular model or size of earplug for a specific individual.

Using an appropriate fit testing device, like 3M’s E-A-Rfit Validation System, we can now determine the Personal Attenuation Rating (PAR) for the individual and if this PAR is acceptable for their noise exposure. Rather than using the averaged SLC80 value, we can now see if Plug A gives enough attenuation for the noise exposure, or that perhaps Plug A does not fit well enough and using Plug B (or C, etc) does provide suitable protection.

Early indications are that a significant percentage of workers using earplugs currently do not achieve the SLC80 value and are therefore at risk of overexposure.

This new technology can assist in providing the worker with hearing protection that has been individually assessed for fit and attenuation.

CASE STUDY

Equipment to improve underground construction safety

An innovative manipulator has been developed to improve safety and productivity in underground construction. Suitable for the mining and building industries, the equipment provides a solution to the significant safety issue of personnel working with suspended loads, especially in confined underground work areas. Local mining contractor Redpath Australia has developed a machine capable of erecting steel beams in underground mines at a much safer and faster rate than the current process using cranes.

The Redigrip PSM (Precision Steel Manipulator), which has seen Redpath short-listed for an NSCA National Safety Award of Excellence, is a hydraulically controlled beam manipulator that can lift beams weighing up to 1.2 tonnes with a reach of up to 8 m. It has already been used to improve safety and productivity at a mine construction project, finishing in three-quarters of the time and incident free.

The idea was born when Redpath Australia was engaged in a tender process for the reconstruction of an overhead crane at an underground mine, where it identified the opportunity to improve workplace safety by eliminating the need for the slinging of enormous beams and columns during construction.

NEW PRODUCTS

The principal breakthrough in the design of the Redigrip is the unusual combination of components and systems, combining mining machinery parts with those used in forestry and agriculture to create a new tool with uses and solutions for projects across a range of sectors.

“While the Redigrip was purpose built to improve productivity for a specific project, it can be easily adapted for use in any industry and the design allows it to be used with various materials,” says Graeme Christie, Health, Safety, Environment and Quality Manager for Redpath Australia.

“The safety and productivity benefits are incredible. The Redigrip eliminates the need for a conventional crane in a confined, underground space and minimises the personnel exposed to potential crush injuries from handling heavy loads, all while completing the work faster,” Christie says.

The Redigrip PSM is a combined effort between Redpath, Mecad Engineering, Doherty’s and M&J Hydraulics, and is capable of 360° rotation, 40° side tilt left and right, 140 mm side shift, 180° primary tilt and 600 mm of telescopic extension, powered by a Volvo L120 front-end loader.

“Finding new ways to make people and machinery safer is something Redpath does on every single project, and the result is a range of innovative machinery which either has features improving its safety and productivity, such as our range of Redbore raise drills, or is custom designed to meet a specific need, like the Redigrip,” says Christie.

The Redigrip PSM is not restricted to underground mines either, with minor modifications making it suitable for safe, flexible and rapid steel structure erection, civil works such as sewerage tunnelling, installation of rising main pipes, and in sheds and fixed plant installations on the surface.

Another potential enhancement to the Redigrip is to use it with a telehandler, which would allow greater flexibility for use with potentially larger sections and allow for greater lifting heights, while still minimising the involvement and risk to personnel.

The importance of CO2 monitoring system in pub cellars Cylinders storing carbon dioxide and nitrogen - which are used to carbonate beer and soft drinks - can be dangerous if they develop leaks, particularly when stored in enclosed spaces like cellars and cool rooms. Leaks can also occur at other points in the system, eg, pipe fittings. An appropriate alarm system alerts people to the presence of a gas leak and warns them not to enter the area.

Carbon dioxide (CO2) leakage is a potential killer for any hospitality venue that sells tap beer and post mix and doesn’t have a properly fitted and maintained CO2 monitor, says Hoshizaki Lancer’s MD Joe Thorp.

Carbon dioxide is used by thousands of hospitality venues to carbonate and provide pressure for tap beers and post mix.

However, CO2 is undetectable by human senses and the presence of CO2 in a non-naturally ventilated space can be lethal in a matter of seconds.

“There is always the potential for pressurised gases to escape from leaking equipment connections or damaged hoses,” said Thorp.“The only way to safely monitor for carbon dioxide leaks and ensure staff safety is to fit a carbon dioxide alarm.

“Under Australian Standards AS5034 it has been a requirement since the end of 2011 for all venues to have such a system installed.

However, when we are installing beer and post mix lines and equipment we see the inside of many cellars and are concerned with the number of venues that have poorly maintained monitoring systems or no CO2 monitoring system installed.

“If a monitoring system isn’t calibrated properly then its effectiveness is at best minimal and may create a false sense of security.”

20 SAFETY SOLUTIONS - DECEMBER 2012/JANUARY 2013

Hoshizaki Lancer has a self calibrating CO2 monitoring system that is designed to take away the risk and the worry.

“The majority of the systems on the market require regular calibration,” said Thorp.

“The Lancer LogiCO2 MkVII safety system has a patented automatic calibration, requiring just the press of one button on an annual basis to test all functions are working properly.

“When combined with a 15-year sensor life, it ensures long-term, maintenance-free operation for publicans and restaurant managers.”

The system can be upgraded to include up to four sensors, with two individually programmed relays that can activate remote warning beacons or ventilation. The product features three preset alarms for continuous monitoring for CO2 in cellars and other confined spaces. The first is a time weighted average reading of 0.5%, highlighting very low levels of leakage to raise awareness to staff of potential problems. The second is a pre alarm which is activated at a CO2 air level of 1.5% notifying staff and allowing personnel to investigate and safely repair any leaks. The final alarm is activated at 3% CO2 presence, chosen to ensure that no one is exposed to IDLH (immediately dangerous to life or health) levels which occur at 4%.The system has a remote digital display, enabling the publican to monitor the gas storage area from the office or elsewhere within the building. The sensor also monitors cellar temperature, displaying the temperature on the sensor as well as the central unit. An alarm can be activated to ensure cellar temperatures remain correct.

Infrared camera for noxious gas detection The FLIR GF306 infrared camera detects and visualises SF6 (sulfur hexafluoride) and 25 other harmful gases.

The thermal imaging cameras are said to be more effective for detecting gas leaks than gas sniffers, because the camera can detect, visualise and pinpoint the leak.

The specialised infrared cameras are able to visualise gas leaks. The camera produces a full picture of the scanned area and leaks appear as smoke on the camera’s viewfinder or LCD, allowing the user to see gas emissions. The image is viewed in real time and can be recorded on the camera’s removable SD or SDHC memory card.

Other features of the range include: it can be used both for finding gas leaks and maintenance inspections; fully calibrated for temperature measurement applications; embedded GPS data in reporting; inspect without interruption of process; reduced inspection time; trace leaks to source; spot leaks up close or metres away; verify repair.

The camera can detect the following gases: sulfur hexaflouride (SF6); acetyl chloride; acetic acid; allyl bromide; allyl chloride; allyl fluoride; ammonia (NH3); bromomethane; chlorine dioxide; ethyl cyanoacrylate; ethylene; furan; hydrazine; methylsilane; methyl ethyl ketone; methyl vinyl ketone; propenal; propene; tetrahydrofuran; tetrahydroethylene; uranyl fluoride; vinyl chloride; vinyl cyanide; vinyl ether.

IMPROVING THE UNDERGROUND WORKING ENVIRONMENT The recent classification of diesel emission as a carcinogenic by the World Health Organization signals the need for Australian mining operations to review their mine ventilation risks and immediately implement any necessary actions that reduce the contingent health risk for Australian underground mining personnel.

A

t a meeting in June this year, the World Health Organization (WHO) declared that diesel emissions cause lung cancer. This statement marks a significant shift away from a previous position that had classified diesel fumes as a ‘probable carcinogenic’.

Specifically, WHO considered scientific research showing that human exposure to substantial concentrations of diesel particulate matter (better known as soot) produced by burning diesel causes lung cancer and is also linked to the incidence of bladder cancer.

The WHO announcement is particularly relevant for underground mining personnel who are required to use diesel-powered equipment within a confined workplace environment. In fact, underground miners are typically exposed to concentrations of diesel exhaust that are more than 10 times higher than other workplaces that use diesel-powered equipment, such as the transport industry.

According to pitt&sherry’s National Mining Manager, Dan O’Toole, “The WHO announcement signals an urgent need for

22 SAFETY SOLUTIONS - DECEMBER 2012/JANUARY 2013

the Australian mining industry to review mine ventilation risks and, where appropriate, implement workplace improvements that reduce the cancer risk for Australia’s underground mining workforce.”

There are a number of strategies available to the Australian mining community for reducing mine worker exposure to high concentrations of diesel emissions. There are principally three potential opportunities to reduce diesel emissions in underground mining environments but these solutions vary in terms of cost, complexity and near-term practicality.

Monitoring and control The first opportunity involves the implementation of improved monitoring and control systems for underground air quality.

Unfortunately, the quantum of improvements that can be secured under this approach are typically incremental and are unlikely to be sufficient on their own. According to O’Toole, “Reduced

emission concentrations are possible but require provision of improved ventilation infrastructure that can be both costly and difficult to implement.”

Lower emissions at source The second approach involves the control of diesel emissions at the source by either (a) purchasing new underground mining equipment fitted with advanced emission control systems, or (b) retrofitting emission control systems to existing diesel equipment.

Low-emission mining industry equipment is becoming increasingly available in the global marketplace. This equipment is being manufactured in response to new emission standards developed by the USA Environment Protection Authority and are being phased in between 2008 and 2015.

While retrofitting remains an option, the availability of the aftermarket emission systems is relatively limited and there are question marks surrounding the potential adverse impact of these systems on both equipment performance and fuel efficiency.

Alternative fuel The third option involves fuel substitution. That is, replacing conventional diesel with biodiesel. Biodiesel is produced from

www.SafetySolutions.net.au

biological feedstocks - hence the name biofuels - using a process of condensation called transesterification.

Biodiesel is often blended with diesel at levels varying from as little as 5% (B5) to complete replacement (100% biodiesel).

Given its higher flashpoint, biodiesel is also less likely to ignite than conventional diesel, providing an additional level of safety for underground mining application.

“The most exciting aspect of biofuels within the context of underground air quality is that biodiesel can be readily substituted for conventional diesel in existing equipment whilst also delivering up to a 90% reduction in diesel particulate emissions,” O’Toole said.

Mark McKenzie, pitt&sherry’s Principal Consultant, Carbon & Energy, believes that the increased adoption of biodiesel in underground mining will require the mining industry, Australian governments and the infant biodiesel industry to work together to address two principal challenges - the supply challenge and the cost challenge.

“Within the context of the Australian petroleum industry, the biodiesel industry is very small and most of the supply is currently being consumed in NSW under the umbrella of a mandated use of 5% biodiesel in all diesel sold in that state,” McKenzie said. “Effective management of the supply challenge will likely require mining operations to establish commercial relationships with small-scale biodiesel producers within the confines of commercial agreements that address continuity of supply risks.”

On the cost side, biodiesel is more expensive than diesel for mine industry applications. Although biodiesel is slightly less expensive than conventional diesel for transport applications, the fact that diesel used within mining operations is not subject to the federal fuel excise of 38.6 cpl means that the biodiesel used in mining operations is currently more expensive than conventional diesel. This problem is compounded by the fact that the energy content of biodiesel is lower than conventional diesel and consequently a greater volume of biodiesel is consumed.

“The higher cost of biodiesel makes the use of this fuel commercially unattractive under current taxation settings. In light of the WHO announcement, there appears to be a strong argument for the Australian Government to incentivise the use of biodiesel for underground mining applications and realise workplace benefits for the Australian underground mining community, McKenzie said. “Such incentives might take the form of producer subsidies for biodiesel supplied to the underground mining industry or government rebates provided to mining enterprises for the purchase of biodiesel.”

The WHO announcement and the recent introduction of both the national carbon price and the Mining Resource Rent Tax (MRRT) highlight the increased complexity of issues now being faced by Australian mining enterprises.

Emergency response

Social networking has changed the way people broadcast and receive information. Every minute, vast amounts of information are communicated via Twitter. CSIRO has developed an analysis tool that helps organisations make sense of massive volumes of social media traffic. The software is providing solutions for a variety of applications including: management of emergencies, reputations and mental health.

T

Social media analysis in action A hospital was recently threatened by a grass fire in Cloncurry, in outback Queensland. The CSIRO ESA software was used to analyse Twitter post and gave the Queensland Department of Community Safety early warning of the incident.

Tweets about the fire emerged well ahead of any official alerts; within minutes, details such as the fire’s location and direction were appearing on Twitter, allowing emergency managers to evacuate the hospital safely.

ESA provided crisis coordinators early notification to prepare their response to the fire while waiting for confirmation from official channels. This meant the evacuation plan could be prepared,

www.SafetySolutions.net.au

providing precious extra time to the emergency management workers on the ground.

It allowed efficient, safe and timely evacuation of hospital staff and patients before the fire got out of control and evacuation became difficult or impossible.

The potential applications of social media information for disaster managers include providing: • evidence of pre-incident activity; • near real-time notice of an incident occurring; • first-hand reports of incident impacts; and • gauging community response to an emergency warning.

How the software works ESA exploits the statistical incidence of words used on Twitter to describe emergency events. It’s trained using historical word occurrences on Twitter from past disaster events. This allows ESA to reveal emerging topics and flag them for investigation. Searches repeated every minute look for words that are used more often than normal and these detected ‘word bursts’ are extracted and stored, and are available for access by incident response agencies via the ESA web application.

The ESA software can: • detect unexpected or unusual incidents, possibly ahead of other communications; • condense and summarise messages about an incident maintaining awareness of aggregated content without having to read individual messages; • classify and review high-value messages during an incident (eg, messages describing infrastructure damage or cries for help); understand the impact of an incident on people and infrastructure; • identify, track and manage issues within an incident as they arise, develop and conclude; proactively identify and manage issues that may last for hours, days or weeks; and • perform analysis of incidents by exploring social media content from before, during and after an incident.

ESA provides situation awareness by using data mining techniques including burst detection, text classification, online clustering and geotagging. These techniques are adapted and optimised for dealing with real-time, high-volume text streams which identify early indicators of unexpected events, explore the impact of identified incidents and monitor the evolution of events.

Dormer said the social media analysis tools were being developed with government, for government - the Australian Government Department of Human Services being a key partner. Business is also starting to show interest.

“We’ve formed an ‘early adopters group’ of innovators in government to help us develop the social media tools beyond the prototype stage, trial them in real situations and give us feedback to make them more useful,” he said.

he Emergency Situation Awareness (ESA) software detects unusual behaviour in the Twitter stream and quickly alerts the user when a disaster event is being broadcast. ESA also stores complete Twitter stream information and allows post-event analyses. Such useful and accessible information will provide timely situation awareness for disaster managers and emergency response agencies.

Responding earlier to bushfires, finding false claims for reputation management and helping address mental health issues are some of the benefits being seen with the introduction of new social media software from CSIRO. Without suitable tools, social media information can’t be used. For example, details about the 2009 Victorian bushfires were reported in real time on social network sites but were not visible to state or federal disaster response agencies.

Alan Dormer, CSIRO Services Science Leader, said that with millions of posts and countless conversations happening every minute, organisations trying to make sense of social media can easily find themselves overwhelmed.

“There are 11.5 million Facebook accounts in Australia and more than two million Twitter accounts, so analysing social media posts to find relevant information is like looking for a needle in a haystack,” Dormer said.

“It’s a classic big data problem. But with our research in data mining, textual analysis and data visualisation, we’re well placed to tackle it,” he said.

So far, organisations are using the software for three main reasons - reputation management, exploring topics and issues important to the community, and early detection of emergencies or outbreaks. And it’s showing promising signs of increasing efficiency and productivity.

Prof Allan Fels, Chair of the National Mental Health Commission, said he has found social media analysis gives his organisation insights into community thinking on mental health and wellbeing.

“We believe mental health and suicide prevention is an issue for all Australians. The CSIRO social media engagement tools help us identify key issues on a daily basis and provide social media reports which are easy to understand and quick to produce,” he says.

The commission plans to use the software to gauge community response to its report cards on Australia’s mental health issues and services. The first is due out later this year.

CSIRO used its own social media analysis tools to find false claims about coal seam gas research that appeared in social media. This allowed CSIRO to address the misinformation quickly.

Gumboots and marine equipment receive ‘S’ mark certification The ‘S’ Mark is one of the leading symbols of compliance in product certification and is provided by Bureau Veritas Certification.

Product certification involves the process of certifying products to ensure that the performance and quality meets the requirements of particular product standards. It is especially significant for personal protection equipment (PPE) manufacturers. Clothing, helmets and shoes must be to the highest quality when they are designed to prevent the wearer from injury.

The ‘S’ Mark certification has become one of the leading representations of product conformance in Australia and New Zealand. Using the ‘S’ Mark logo for product certification can have a strong point-of-sale impact and is used as a marketing tool by prominent PPE companies.

One such company, Bata Company (NZ) Ltd, looked to Bureau Veritas Certification to provide product certification for its occupational protective and safety footwear.

Bata Company produces 200,000 PVC gumboots per year as well as importing brands including the Bata Industrials range. They position themselves as being a company that is not only focused on safety but also places an emphasis on comfort and health.

“Product verification by Bureau Veritas has allowed us to establish a competitive advantage by increasing our validity … We are able to give [production certification] to our customers and this is used as a guarantee; this helps to increase confidence in our customers,” said Tony Harmer, Operations Manager at Bata Company.

Hutchwilco, also a client of Bureau Veritas Certification, certifies its buoyancy aids and marine safety harnesses to ‘S’ Mark.

It was initially built with asbestos in mind, but its uses extend to medical waste, contaminated soils, PCBs, veterinary waste, toxic woods, emergency services contaminated equipment and quarantine.

It comes in four different sizes to suit all needs and products: the 1 m3 certified for packing group II & III, the asbestos-specific 1.5 m3, the larger 3 m3 and the De-con Hazibag.

The 100 L De-con bag is specifically designed for the emergency services to transport their contaminated equipment. It comes with water-soluble, onetime-use liners. The contaminated equipment gets loaded into the water soluble bag, which in turn goes into the Hazibag to be sealed and transported to the decontamination centre.

There the bag can be opened and the contaminated equipment/clothes can go straight into the decontamination chamber or washing machine while still inside the plastic bag. No secondary handling or contact with the contaminating agents. The bag will dissolve in the wash when it comes in contact with the water.

Remote explosive unit for mining applications The Merlo Remote Explosive Blasting Unit provides a solution to keep mine personnel safely away from the hazards of open pit mining.

In response to the need to remove personnel from the high-wall area, Grange Resources and pitt&sherry have developed a Remote Explosive Loading unit. This unit is based on a Merlo Telehandler which has been modified to house and operate a remote feed system. The system is used to charge the holes with explosive material. The Merlo Machine has a boom reach of 18 m, allowing the operator to operate the charging process from the relative safety of the Merlo cabin, parked outside of the known danger area of potential rockfalls.

systems, training records and legal requirements.

The software can be configured and has functionality for reporting, notification, tracking and alerting. It is scalable to support functionality, provides for flexibility in user management and additional users can be activated as required.

It also supports multisite management to assist with one system for many work site locations and transient workers.

The companies recently received the WorkSafe Tasmania Award 2012 for the Best Solution to an Identified Workplace Health and Safety Issue.

“Having our work recognised by WorkSafe Tasmania is a great honour for pitt&sherry and Grange Resources. Mining fundamentally takes place in a harsh and often hostile environment, making safety an important priority,” said Dan O’Toole, Director/ National Manager, Mining, pitt&sherry.

By conducting a comprehensive workplace risk assessment and control (WRAC) analysis, the highest risks in the open pit mines were found to be hazards related to rock falls and slope failures.

The Merlo unit represents a significant improvement in OHS procedure and was recently accepted into the minerals processing unit (MPU) code of practice that recognised the safety advantages of the equipment, allowing it to be used as an MPU. Any mine or quarry with either high-wall operations or rock-fall hazards stands to benefit from the technology.

“There is increasing pressure on the mining industry to improve safety and productivity, while reducing costs. Robotic machine guidance technologies such as the Merlo are providing attractive alternatives to traditional mining techniques,” concludes O’Toole.

OHS Leaders Summit Leading companies across Australia are now, more than ever, looking for ways of increasing safety for their workforce by implementing and investing in new technologies and services so that they comply with new rules and regulations. The OHS Leaders Summit being held from 19-21 February 2013 at the Sheraton Noosa Resort & Spa, Queensland, provides the perfect setting for senior safety professionals to network and hear the latest from health, safety and environment (HSE) thought leaders, both locally and internationally.

Chairman of ISQEM (International Safety Quality Environment Management Association) Wayne Harris (pictured) will be the master of ceremonies at the summit. He also sits on the Board of Directors of the World Safety Organization (a UN-NGO) and Date: 19-21 February 2013 his voluntary work and contributions Venue: Sheraton Noosa to the industry are fundamental in the

Resort & Spa,

Noosa Heads, Queensland continual advancement and acceptance Website: www.ohsleaders.com.au of the HSE profession.

Harris has advised major international organisations, both private and governmental, on key issues of strategy and organisational risk and safety management for over 29 years in Europe, the Middle East and the Asia-Pacific region. In addition, he is a regular speaker at international conferences around the world.

His presentation ‘Global HSE Management and Future Leaders within the industry’ will focus on the global approach to professional HSE management and how to make the change from routine compliance to becoming an international leader within industry. He will talk about: • Taking HSE to new levels of international management standards; • Influencing your Board of Directors and gaining acceptance of HSE; and • International approach to HSE leadership and operational efficiency and profitability.

He will have a major impact on the event, bringing with him the true international approach in relation to safety leadership and management practices.

The national harmonisation of the OHS laws (WHS Act), the increasing number of younger and older workers, and other workforce challenges encountered in Australia all add to the increasing complexity of a national workplace. The OHS Leaders Summit specifically caters for senior safety professionals wanting to keep informed and up to date on current occupational health and safety strategies and products that are designed to comply with new regulations.

This year’s OHS Leaders Summit will play host to 150 senior directors from within the OHS sector. Attendees will have the opportunity to meet and interact with one another through a series of scheduled one-to-one business meetings and additional networking activities. Leading technology suppliers will be on site and the strategic summit sessions, which include best practice examples of technology innovation, are all led by senior health and safety executives, both locally and internationally.

The recent crane disaster in Sydney has highlighted very publicly why industrial equipment safety is so important. For those of you who didn’t hear the news, diesel fuel caught alight and engulfed a 65 m crane at the UTS Sydney construction site and the crane arm then crashed to the ground. Luckily, no one was seriously injured, but if the boom hadn’t have been steered clear of the busy street below, it could have been a disaster of enormous proportions. It was reported that workers had raised concerns over fuel leaks in the crane some weeks before this incident and a safety inspection had been carried out. What went wrong? Was the fuel still leaking? I’m sure all will be revealed as WorkCover NSW is now conducting a full investigation.

Moving on to news from The Safety Show in Sydney - it was a great opportunity for me to meet with a number of you and hear the latest industry news and innovation in products, some of which are featured in this issue. One such product is the Hazibag, which is used for the transportation of contaminated equipment and/ or hazardous waste, such as asbestos.

Another is the Sonamax earplugs, which are shaped to the user’s unique ‘ear-print’ for maximum comfort while providing a noise-blocking acoustic seal.

Also, congratulations to Mansi Gandhi (previous Safety Solutions editor). She has safely delivered a healthy baby boy and is enjoying her time with him.

See you in the new year!

Opinion Fixed ladder research calls for rethink of standard The ink is barely dry on the draft revision of the most popular Australian Standard for safety but new research by the country’s most prominent ergonomist may well force the committee to rethink AS1657.

The draft revision of AS1657 - which covers the selection, design, risk assessment and testing of fixed platforms, walkways, stairways and ladders - closed for public comment in September. It may well need further revision, according to ergonomist Professor Caple, whose study delivered a host of findings warranting larger research into equipment design.

“Some of the issues that have come out of this study could be deemed to be life saving if the behaviours that we saw could be repeated in a larger study using a broader section of the population,” the Professor said.

The Caple study, which was sponsored by fall prevention company Workplace Access & Safety, involved analysis of videotaped footage of Australians as they used various types of ladders. Among the outcomes were that falls are more likely from a vertical rung ladder than an inclined step ladder.

Professor Caple also found extended stiles that allowed users to maintain their hand grip while stepping down onto the first rung of a ladder reduced the risk of falling.

“When we have a system where the hands are behind the shoulders and the centre of gravity of the body is moving backwards, we have a significant risk of falling,” Professor Caple said.

“What we are looking for in the design standards is an appreciation that bodies move in a three-dimensional space and that space is dictated by gravity. What they need to maintain is good support using their three points of contact regardless of whether it’s an angled or a vertical ladder, particularly as they transition from the top of the ladder on and off the landing.”

“If the stiles and or the treads on the vertical ladder are too close to the wall, it increases the potential for someone to fall because they haven’t got good stable support of their foot to stabilise their centre of gravity over the tread,” Professor Caple said.

While AS1657 has been silent on the issue of spacings between the bottom rung and the landing, the Caple study found a lack of uniformity presented an extra hazard.

“Because they [the ladder users who were the subject of the study] couldn’t see the treads on a vertical ladder as they were going down - they tended to, when they got to that bottom tread, either look down and then take a more careful step onto ground level or they might stumble and miss it completely,” Professor Caple said.

“It was more problematic when the bottom tread was close to the floor. We learned that, as a principle, it’s a good idea to have equal distances between the treads from the floor height to the landing height.”

The Caple research has been welcomed by the AS1657 review committee, says one of its members, who is also the study’s sponsor - Carl Sachs of Workplace Access & Safety.

“I commissioned this exploratory research to test some of the assumptions the committee was making while drafting the revision of AS1657,” Sachs said.

“This is the most popular safety-related Australian Standard of all time and deals with some very serious risks, so it’s vital that its recommendations are manageable and add to everyone’s safety.

“Professor Caple has found there certainly are questions that need to be answered and I hope this will encourage larger research to be sure AS1657 really is on the right track.”
