Ladies and gentlemen welcome to this edition of this wonderful magazine. Our aim is to keep you informed on risks which we encounter everyday as we do business. In this issue I will talk about cybercrime which is a concern to governments and the cooperate world. The Oxford dictionary denes cybercrime as criminal activities carried out by means of a computer on the internet. Others dene it as crime which a computer is the object of the crime or is used as tool to commit the offence. This could be child phonography, hate crime or hacking of organizational computers. With the amount of data stored in data bases around the world, this has made the use of the internet very important. Data can be easily accessed at the press of a button. The infusion of the internet has changed the way we handle data and at the same time more threats to held information has arose with this infusion.

Fraudsters have managed to transfer money from different bank accounts and have remained unapprehended. Cooperate data has disappeared when computer induced viruses and malware attacked company data bases. In the USA a teenager boy managed to hack into the Pentagon computer system for fun. This exposed the data security of the Pentagon. Software designed to disturb or cause damage to computers have been designed and are being sent out to different computers through emails which once opened pass the virus to the computer leading to its malfunction. In the last year cybercrime has been rmly established as one of the biggest threats to democracy, privacy and health and safety

Terrorists groups are also now using the internet to champion their cause. While money laundering is at a huge scale on the internet. Recently cyber criminals have been demonstrating that their activities are becoming more about nancial gain and recognition. Although this was always the motivation, after all the easiest means of making money is to get hold of personal records and sell them on the dark web. We are witnessing a notable increase of attacks for this purpose. To prevent cybercrime from taking place in organisations there is need to employ cyber security. Cyber security is the body of technologies, processes and and practices designed to protect networks, computer programs and data from attack, damage and unauthorized access. This include Application security, Information security, Network security, Operational security. Business continuity plans and End user education. One of the most problematic elements of cyber security is the quality and constantly evolving nature of security risks. In other words the threat is advancing quicker than we can keep up with it. As a result cyber criminals always change their ways and continue to commit crimes and untold damages to unsuspecting people. In conclusion the risk of cybercrime is real and as risk personnel should be able to come up with security measures to minimise this risk.

Mine Security

Mining sites are hard to secure because of their vast sizes and remote geographical locaons. Crime on such sites connues to be a challenge with mining companies spending large porons of their budget on technology for both detecon and prevenon of the. Perimeter control and illegal underground mining also present challenges where mine security is concerned. African mines must unfortunately contend with the problem of pirate miners and illegal mining acvity.

Pirate miners – who many mes slip underground unnoced – are oen heavily armed and cause damage to mine infrastructure threatening the safety of legal workers. The loss of precious metals however should not be taken as the sole indicator of the level of the, the loss of related mine property counts as well; both components are crucial to the existence of any mining operaon.

Yet another challenge in mining security is the specialized requirements of mines. The needs of one mine will always differ from that of another for the most part. A high value mine for instance, will require extremely high levels of security to protect its products whereas a coal mine would place more focus on operaonal and management issues, emphasizing on surveillance

to ensure that producvity remains within acceptable parameters.

Perimeter control, video surveillance, communicaon, Radio Frequency Idenficaon (RFID), access control and or intrusion detecon are some of the soluons to the unique security issues at mines according to Mark Freer and David Hunter of Bytes Systems Integraon. The advent of the Ethernet has brought along integrated soluons granted broadband and fibre cabling. Current systems house not only the requisite security component but in addion offer management and surveillance tools that are vital to high producon levels and quality The internet as a backbone of integrated soluons connues to allow for individual systems to be connected via fibre cables, microwaves, wireless links and ADSL.

When placed underground, video surveillance aids the process of monitoring miner safety by viewing rock falls or accidents in real me. By result, surveillance can speed up search and rescue mes and help inhibit the acvity of pirate miners. With surveillance in mining, the spotlight is generally on the behaviour of people rather than on building management as it is in another sectors. The use of this security opon is however curtailed by the length of area of

underground tunnels which cannot be effecvely monitored by cameras. Temperatures underground may, in addion, not be conducive, being too hot and humid, for this technology to be employed.

Radio Frequency Idenficaon (RFID) and sensor systems also serve to shorten rescue mes substanally, aid the process of capturing pirate miners, provide for beer perimeter control and keep beer track of raw materials from underground to the surface. Improved communicaon especially underground can greatly improve safety. Access control also goes a long way in ensuring security by using ID cards to make certain that the entry and exit of miners is strictly monitored. This proacve method can however be augmented by the use of renal or finger print biometrics where fake access cards can be used; whilst many mines operate access control systems, no one soluon has offered true reliability coupled with high performance.

Noteworthy is that while biometric systems offer great security, many of the exisng biometric readers on the market remain unreliable. These present too many false reads and are best used only within stable environments such as when it is not too hot or cold, indoors and with clean fingers.

Weighing up risk

In excess of 60% of the SADC group of countries combined GDP comprises goods that are weighed at some point in their transition to market, whether locally or as exports. Weighing is therefore profoundly important.

Risks are Higher in Industrial Sectors

Weighing breaks down into basically retail weighing, comprising goods sold through large and small retail outlets, and the much larger component termed industrial weighing The risks associated with decient weighing within the retail sector are comparatively low, but the same cannot be said for industrial weighing and these risks have been growing

Prior to the advent of the digital age, globalization, expanding trade within the SADC region, the introduction of axle weighing overloading regulations throughout SADC, the introduction of SOLAS regulations which has impacted all global containers exports by sea, industrial weighing was a mundane process involving trucks driving over weighbridges with the results being written down, and eventually captured into an accounting system.

In this “mundane age” of industrial weighing risks of decient weighing were low, and the scale companies providing industrial weighing equipment and services were equally mundane The business of these participants was essential the installation of scales and the maintenance and repair thereof

Changing Dynamics are Increasing the Risks

The term “decient weighing”, includes weighing done on devices that are unapproved, weighing done on devices that are inaccurate, weighing software that is not compliant and weighing software that does not enable real time weighing data to be supplied.

Understanding the signicant risks associated with “decient weighing” in today's rapidly changing market place requires one to dissect the associated risks that arise from directly from the new trade dynamics, laws and regulations and technologies that impact on and shape our industrial trade ows in today's global economy

Each of these dynamics and the associated risks can be

summarized as follows:

1. Introduction of axle weighing overloading regulation: nd In South Africa, the Road Trafc Act 22 Amendment requires that, for every load, the transporter and or consignor must produce and retain proof that each vehicle in question is loaded to within permissible limits Government weighing stations both in South Africa and the rest of SADC then weigh vehicles to ensure they are within limits.

Failure to be able to prove full compliance with the Road nd Trafc Act 22 amendment will result in large potential nes for non- compliance, potential nes for overloading at government weighing stations, the possible required discharging of cargoes at government weighing stations so as remedy overloading causing resultant delays and added costs and nally the possibility of insurance cover being rendered null and void in the event of an accidents.

2. Compliance with SOLAS regulations on containers shipped by sea:

Jan - Feb 2023

Weighing up risk

Validity of Transporter's Third Party insurance cover called into question without proof of compliant axle loading and total loading

IMO SOLAS regulations require that, for every container to be transported by sea, the owner of that cargo must determine the gross mass of the container on an approved weighing device, and must generate documentary proof thereof in a specied format.

Failure to comply with these regulations will prevent containers being allowed into departure ports risking delays and added costs.

3. Controlling in transit stock losses

The volume and value of goods transported around SADC countries by road are vast.

Stock losses in transit can only be controlled and managed if volumes of goods load and the point of loading and the volume of goods discharged at the point of loading are determined with great accuracy

Weighing is the obvious way of establishing these values, and is highly effective when these values are integrated into an overall ERP system so as to make real time reconciliations possible.

Solutions to Mitigate Weighing Related Risks

Weighing related risks can only be mitigated through management having access to accurate and compete weighing data on a real-time basis. The provision of these types of solutions are therefore key

While a number of software companies have sought to provide these solutions, they have generally lacked the base weighing knowledge and understanding of weighing devices, which has curtailed their success.

With one notable exception, most of the scale companies that historically focused on the supply, servicing and

repair of scales, in the “mundane age” of weighing have continued to focus on service and repair of scales.

The notable exception is Sasco, which traded as during the mundane age” of weighing as the South African Scale Company Sasco commenced trading in 1910 and was the market leader during both the mechanical age of weighing and in the in subsequent electronic analogue age of weighing

Sasco transformation into the leading weighing data systems provider has been achieved by securing rights to the most advanced digital weighing technologies, integrating these devices with micro-computer systems capable of providing fully automated weighing solutions and the complete integration of this data to real- time ERP and cloud based solutions.

Legrand AlphaRex 3 and MicroRexadvanced programmable time switch technology

Legrand's AlphaRex³ and MicroRex me switches are designed for easy programming and ensure high-clock precision in industrial, commercial and domesc environments. Legrand devices, with advanced me switch technology, are used to switch an electric circuit on or off at selected mes during a pre-programmed me period. These analogue and digital me switches also have an automac return facility and a permanent forced switching on or off override control.

The AlphaRex³ series has a user-friendly standardised text guided programming facility, with a high-resoluon digital display and backlight. There is a standard, single data key for all devices in this range to allow quick and easy transfer of programmes to other me switches and for creang back-up copies.

Programming with clock precision to the second is controlled directly on the me switch, or outside the distribuon board using a PC and Legrand's AlphaSo programming soware. Other features include an EEPROM memory, which prevents sengs being lost and the facility to programme the clock prior to despatch. Once the unit has been programmed, the informaon will remain installed even if the

switch is not connected to power. The baery can be removed without having to uninstall the me switch from the distribuon board. AlphaRex³ me switches are available with standard and mulple funcons, with a daily or weekly programme facility and a clock working reserve of six years. Typical applicaons for this series include industrial pump staons, security alarms, indoor and outdoor lighng, air condioners, heang and venlaon systems and swimming pool heaters. These me switches are also compable with alternave renewable energy systems, like photovoltaic panels.

MicroRex me switches offer easy plug and play installaon for daily and weekly programming. By simply seng the analogue switching dial during start up, the me is automacally set using the fast-run mode. In the event of a power failure, the me is automacally reset.

MicroRex devices, with analogue and digital dials, are 24 hour and seven day me switches for DIN rail and wall mounng, with a five year running reserve. These units have the capability for mulple programmes, which ensures opmum me seng flexibility. MicroRex me switches have an

LED status indicator, a precision clockwork of 0.2 s/day and are controlled by either a quartz or synchronous motor. For increased safety and user convenience, there is an automac and manual and advance/over-ride facility

The MicroRex series is designed for dependable use in many applicaons, including periodic lubricaon of machines or regularly repeated switching of pumps, feed conveyors and sprinkler systems. This device is also suitable for short periods of controlled defrosng.

Other me switches in the Legrand range are designed for precise control in security installaons – for access points; electric fences and alarms – as well as for use in industrial installaons, including pump staons, filters and conveyors. Legrand me switches are also used for the lighng of commercial boards and signage, as well as for street lighng. Time switches in agricultural applicaons are used for irrigaon and sprinkler systems and for cyclical programmes, like animal feed systems.

Solutions for Recovery boilers and Coal red boilers

The solutions used by Heat Management are:

· Infrasound fouling prevention

· Optimized steam soot blowing

Infrasound fouling prevention

Recovery boilers typically suffer from build-up of deposits in the duct between ECO and ESP (electrostatic precipitator). Infrasound cleaning (low frequency acoustic cleaning) is a fouling prevention method with unique power and cleaning range.

Typical results are:

-Solving clogging issues

-Drastically reduced need for manual cleaning

-Stable pressure drop over the duct

In coal red boilers the applications are mainly Economizers, Rotating Air Preheaters (RAPH) and SCR catalysts.

Typical results are:

-Stable pressure drop over RAPHs and SCRs

-Heavily reduced or eliminated use of steam soot blowing

-Reduced wear of heat exchanging surfaces

Infrasound system operation

The infrasound (15-30 Hz sound) is typically generated for 2 seconds every 4 minutes, keeping the heat transfer surfaces of catalyst surfaces clean continuously during boiler operation.

Compressed air, 6-8 bar(g) (85-115 pis(g)) is used.

The powerful infrasound waves are transferred to the ue gas, increasing the turbulence temporarily and ushing ash from surfaces before it has accumulated/sintered into thick layers.

The infrasound has a cleaning range and cleaning effect far superior to other types of acoustic cleaning, typically using 75-300 Hz. 12 infrasound generator are enough to cover a large cleaning area, such as a whole goose-neck duct after a recovery boiler or a whole SCR reactor on a coal red boiler

Optimized steam soot blowing of retractable soot blowers

Soot blowers in recovery boilers are generally operated non-stop, to keep the ue gas path clean and prevent the fouling and sintering of accumulations on heat exchanger surfaces. In many cases this is not enough, with resulting downtime for manual cleaning. Heat Management's optimization can increase soot blowing capacity by 100 %, without installing more soot blowers or steam headers. By introducing a simple local control on each soot blower steam (poppet) valve, existing soot blowers can be upgraded to one-way soot blowing, without taken the boiler down and disrupting the chemical recovery process. During boiler shutdown, the control system is upgraded to achieve overlapping operation of soot blowers. The

technology constitutes a step-change in soot blowing technology, doubling the capacity (starts per day) without installing more soot blowers or consuming more steam. If more starts is not top priority, the technology can be used for saving 50 % of the steam consumed by sootblowers.

To sum up, by equipping the sootblowers with our actuators for regulating the steam ow locally we can obtain:

-Up to 50 % reduced steam consumption of the steam soot blowers

-Double the soot blowing frequency

-A combination of above

Building design must incorporate effective disaster management

All building designs must incorporate effective disastermanagement systems to allow for safe escape and the control of re and smoke. A minor design aw could potentially place people, equipment, and property at risk of death and destruction, ASP Fire CEO Michael van Niekerk warns.

All buildings in South Africa need to comply with the requirements of the National Building Regulations and Building Standards Act, 1977 (Act No. 103 of 1977), Fire Protection, as set out in SANS 10400 Part T: 2011 Effective re-safety solutions take into account the dimensions and construction of the building, the materials used, and the occupancy and storage of items. These all fall within the prescriptive requirements set out in SANS 10400-T

Any digression from the prescriptive requirements requires a rational design to be completed in accordance with the re engineering methodology framework requirements of BS 7974. The Application of Fire Safety Engineering Principles to the Design of Buildings, supported by the published documents form an integral , part of the BS 7974 framework.

A rational design is the performance-based design of re safety and prevention mechanisms and strategies in a building in order to provide the same or better re safety levels of the National Building Regulations, where the prescriptive requirements cannot be applied. This process is not elective, inasmuch as that only certain parts of the framework may be used, or that the results of the process are subjective or optional.

A rational design commences with a re risk consultantsuch as ASP Fire visiting the premises, or reviewing a set of new building plans, to undertake a comprehensive evaluation of all areas of the property to inspect all areas of re safety and risk in detail.

Correct and proper re engineering principles are appliedto ensure that the design complies with the life, building, re behavioural and environmental re safety objectives ,required by law According to Van Niekerk, the three main causes of re are electrical, arson and heating equipment. “In the event of a major re that results in immense damage and the possible death of occupants, the re engineer will be held liable. Rational design takes into account the behaviour of a building during a re, meaning the structure must be designed accordingly, thereby minimising any potentially devastating impact.”

Fires can be dealt with through three main actions. The rst is controlling the growth of the re to prevent it from spreading. The next is suppression, which involves cooling the re rapidly Finally, extinguishing the re means that there is no heated substance remaining Evacuation should also be safe and easy while allowing , unrestricted access for emergency services. The installed re detection system must be able to detect the re assoon as possible, warn occupants and allow them to , escape in time

The qualitative review under rational design includes an architectural review, re safety objectives, re hazardsand risks, trial re safety designs, and worst-case rescenarios for analysis. For example, consultants often ignore the building roof's geometry and the required ,

substitute rectangular volume used in smoke-ll formulae.

The next step is quantitative analysis according to BS7974. Here the main focus is on the development of re within the enclosure of origin, the spread of smoke, structural response and re spread beyond the enclosure of origin, detection of re and activation of re-protection systems, re services intervention, and evacuation ofoccupants.

Assessment against criteria is the nal step, where the re safety designs developed during the engineeringanalysis are assessed to ensure that the objectives established at the beginning of the process are in fact , , met.

Upon the completion of the re risk assessment anddrafting the rational design report, ASP Fire provides the client with practical actions to implement The report comprises a detailed and documented objective re-risk assessment, as well as re engineering calculations andanalysis where required, covering all aspects of re risk and safety

“This guides the client in protecting its business, employees, and customers by providing prioritised recommendations for action, in order to rectify problem areas and strengthen existing re-safety procedures. This also ensures that the client complies with re-safety regulations for the protection of life, property, and the environment,” Van Niekerk elaborates.

As part of its value-added service, ASP Fire also works closely with insurance brokers and underwriters to address a client's re risk based on the outcomes of the

Surveillance System from Secu-Systems

Charles Harrison of Secu-Systems says that in essence there has been a fundamental change from traditional perimeter intruder detection systems. Typically, mining operations now tend to spend less money on installing physical barriers such as fences and have moved towards investment in bre based technology, wireless point to point , camera following camera or beams, typical intrusion solutions on critical infrastructure internally, due to the complexity of operations and the sheer distances that need to be covered.

He adds that another prompting factor towards additional technology adoption is that once an intrusion has been detected, the time taken for a reaction team to nd and reach that point is often excessive, with criminals having entered the facility and further detection proving nigh impossible due to the vast area to be covered. The trend is to institute the peeling-onion strategy from the

inside out , says Harrison. This allows for 360° wide area surveillance solutions On large sites that include opencast mines or even country borders, physical barriers do still play a role but detection options such as high-end thermal and day/night HD camera solutions are being strategically deployed in high-site locations.

This deployment is often coupled with Australiandeveloped Panoptes military type Moving Target Indication software This allows long-range ground-based surveillance sensors to cover 20 to 30 times more area with the same assets. Further, it allows for multiple target identication and tracking autonomously and simultaneously Cameras can easily detect movement down to 4 pixels.

This software can also be coupled with ground radar in areas that allow for it, such as fairly at areas whereby slew to cue options can be used. The cost benets are that it is the surveillance system cheapest per square

kilometre available on the market.

Thermal tags issued to enrolled users and utilised in conjunction with thermal cameras, allow mines to differentiate friend from foe Harrison cautions that because this is a military application, end user certication is required.

He adds that commercial cameras can attain detection radiuses of only 2.5 km, whereas military-spec cameras, such as the FLIR HRC-X, can attain detection distances of up to 17.8 km or the FLIR PT-602CZ can attain target detections up to 9.2km. This makes these cameras extremely benecial on large sites and in ambient conditions of total darkness, smoke, dust and light fog Worth noting is that while thermal cameras give users the ability to see what is going on, irrespective of the level of light and in adverse weather conditions (since they rely on heat to detect movement or motion), they cannot be used

for personal identication purposes Therefore, a combination of thermal and traditional cameras is suggested as best practice.

Return on investment through surveillance camera adoption is guaranteed. Harrison cites the case of a mine that is currently installing new cameras. “The actuaries have performed calculations on the four new cameras in terms of their cost effectiveness and in only three weeks the cameras paid for themselves twice over This was primarily due to the fact that each week their footage led to the arrest of between 80 and 100 Illegal miners. Incurred losses from illegal mining have been totally obliterated. The successes we have experienced here have led to us embarking on a drive to enter the anti-poaching arena with our technology solutions.”

FENCE INTRUSION DETECTION SYSTEMS

movement to people and animals, while protecon remains h24 acve. This is an important advantage on other tradional soluons both in industrial and residenal areas, where people can pass by the fence and vehicles can be parked very close to it without triggering any alarms. Besides, the plasc fiber woven through the fence is safe, because only light is transmied, not electricity, so it doesn't aract ground loops or electromagnec interferences.

There is a well-established, reliable technology for perimeter intrusion protecon on flexible fences which enables the owner to react promptly, because the system detects real intrusion aempts before the intruder has got inside the property. The system LiteFENCE, which is 100% made in Italy by Naria Security, has proven extremely effecve over the years, as well as easy to install in every environment. The same technology can be also applied to barbed wire or metal rope running on top of perimeter walls.

The LiteFENCE system combines an analysing board (LiteFENCE) with a performing, sunlight resistant plasc opcal fiber (LiteWIRE) and specific tensioning bolts. LiteFENCE reveals the intrusion aempts which result in a flexion of the fence: climb over and li of the fence, as well as aempts to create a breach. The analysing board communicates to any alarm panel via a normally closed relay. Aer an alarm, if the fiber has

remained intact, the system resets automacally, and goes on working regularly This intrusion detecon system can easily suit sloping grounds and perimeters of irregular shape because the system runs along the fence and becomes one with it. The plasc fiber cable is “woven” along the mesh in two or more passages and is connected to the analysing board LiteFENCE: this board detects when the fiber is flexed or interrupted, because the intensity of the light signal transmied in the fiber changes. Vibraons do not flex the fiber and do not result in changes in signal intensity, so the whole system is insensive to vibraons: for this reason, it is parcularly robust to false alarms. Unlike other technologies on the market, LiteFENCE is effecve in any weather condions (rain, snow, wind, fog…) as well as in presence of small animals or birds.

As the an-intrusion system and the fence are intertwined, the nearby area remains free and available: this guarantees freedom of

The analysing board is incredibly user friendly: it has a built-in power meter, which help the installer monitor if the plasc fiber is being placed correctly or idenfy any problems. Once the fiber has been installed and the sensivity level set, no further calibraon is needed. Temperature and humidity slow changes are compensated automacally by the board. Vegetaon growing slowly on the fence does not interfere with the system either, so there is no need of regular or constant maintenance Of course, it is good pracce to trim vegetaon when it becomes heavy and interferes with the flexion of the fence. Unlike tradional glass fiber, plasc fiber is very easy to handle, terminate and repair for everyone, because no skills or expensive tools are required. Pung a connector on the cable only requires a few seconds, and the reparaon of a plasc fiber cable can be carried out quickly and inexpensively by any installer everywhere.

Security soluons over plasc opcal fiber have been on the market for more than ten years and have proven very effecve and easy to manage. This perimeter intrusion detecon system is as reliable as all the other security soluons developed by Naria Security, which engineers and manufactures also an-the systems for copper wires, photovoltaic panels, farm and industrial equipment and machines.

Tubebarrier

The Tubebarrier is a temporary ood defence; quick and easy to deploy to prevent ooding of water in urban and rural environments As well in case of industrial leakage/seepage or temporary water storage.

Which hazard(s) is the innovation designed to mitigate?

Fluvial oods: resulting from discharges that exceed ood protection levels; the high-river discharges are caused by heavy precipitation in the river basin.

Heavy local precipitation (rainfall events): results in 1) (urban) oods due to exceedance of drainage capacity, and 2) ash oods, dened as rapid ooding of low-lying areas, generally within a few hours after heavy rainfall events such as thunderstorms.

How does the innovation work?

The Tubebarrier is an innovative temporary exible ood barrier that can be installed without the use of electricity, pumps, compressed air and / or a lot of manpower The Tubebarrier consists of elements of 10 meters that can easily be connected to each other, by a special design zipper, making the temporary dike as long as necessary

The principle is that we use the upcoming water from the ood to stop the same water So "Fighting water with water".

The Tube consists of a hollow tunnel that is held up by reinforcing slats, with a stability ap in front of it. When the water rises, the water runs on the ap and also in the Tube itself, because there are inlet holes at the bottom of the Tube. Due to the weight and therefore the pressure of the water, the Tubebarrier gets its stability The innovation works through so-called communicating vessels: when the water is high the tube lls up and as soon as the water is gone the tube empties itself

The Tubebarrier is capable for overow (not turning over once the water reaches a level higher than its capacity), which increases the safeguarding properties The Tubebarrier is stored like an accordion (compact) and installed quick with a short installation guideline. The barrier is xed into the ground with ground plates or anchors (depends on the surface), and operates independent from electricity After usage, the Tubebarrier

can be folded back together in the box and easily be transported to a storage facility for reusing This way 100 meter Tubebarrier can fold back to 6 meter Added value / main differentiating element from conventional approach(es)

Quickly to deploy (100 m/hr with 4 people) and to remove. Cheap, efcient and secure. Alternatives are slower, more difcult to organize during times of oods and less exible for different surface conditions.

Critical success factors

Success factors:

- Quick to place; installation doesn't need much people and equipment.

- Relatively cheap; for installation of a permanent ood defence is more complex.

- Reusable; can be used more than once.

- Multi-use on different locations; one Tubebarrier can be used at multiple locations.

LOCK SECURITY DEVICES, SECURITY FOR PROPERTY

A lock is a mechanical or electronic device that is released by a physical object allowing the secured device to open. The history of locks goes as far back as 4000years were the Mesopotamians used locks to secure their properes in ancient Babylon. This was later adopted by the Egypans who used wood and bronze in the design of their locks. As history would reveal, people like Yale and Chubb became renowned because of the security their locks provided. Padlocks were used to secure doors and trunks of very rich people as they were very expensive for the ordinary people. However with the advent of me these simply gadgets became affordable and available to most people both the rich and the poor

Military Armouries had to be secured with Chubb safe locks which made it very difficult for anyone to break into or enter them without a key. The same thing with banks, vaults were secured with Yale or Chubb double bolt locks. This is what made them secure and gave the public confidence in having their precious items and money

deposited in them.

In ancient mes and during the slave trade in Africa people were chained and secured with a lock which needed a key to open. Today handcuffs use the same principle. The use of a key and lock has gone further and is used to start engines in motor mobiles and also to turn the engine system on and off. The key then plays a vital role in the security of property.

Digitalisaon has brought with it digital door locks. A digital door lock is a combinaon door lock which allows a person to enter and exit a room without the need of a key, instead a pin code is used. This solves the use of carrying keys. Most travel bags are fied with combinaon locks. Most hotels in the world now use an electronic card as a key. The card is inserted into a slot in the door and once accepted by the electronic sensor in the door, the door is opened. Finger prints or hand prints are used also as keys to open security vaults and highly secured offices. These gadgets are programed to recognise the finger or hand print of the people allowed access to these

buildings or offices. The advantages of these locks is that, they cannot be picked, they also remove the worry of keeping or carrying keys in safe places and they remove the worry of losing the keys.

As already alluded too, keys are there to offer security. It does not maer whether they are mechanical or electronically manipulated they have to be strong and hinder unwanted persons from entering or unlocking were they are not supposed to do so. Some security firms in South Africa and Zimbabwe operate a key and lock service, were they open doors for clients who will have lost their keys or in some cases misplaced them. This come at a high cost. They ensure that their service is thorough and do not damage the locks they work on. In most cases clients are advised to change locks aer this service is done. It will take me for mechanical locks to disappear as most developing countries sll use them because of their affordability and easy to use as compared to the electronic and digital key which is very expensive to install.

pixels, it offers real-me thermographic images in high speed.

The compact and high-performance infrared camera has a temperature range of -20°C up to 900°C, with an oponal upgrade to 1,500°C. It can be delivered with exchangeable opcs, industrial thermal imager equipment and it comes with an extensive license-free thermography soware package.

Areas of applicaon for the thermal imagers

Optris PI 400

Instrotech, local distributor of process control instrumentaon and specialised systems, has on offer two products specifically for applicaon in the measurement and control of temperature, the Optris CSmicro LT pyrometer, for cement manufacture and Optris PI400 infrared camera.

CEMENT MANUFACTURE and Optris CSmicro

LT pyrometer

Temperature is a crically importance component in the process of making of concrete, and specifically, the importance of controlling the temperature before the concrete is deposited. Opmal temperature of the concrete must fall within the range of +5°C and +55°C, a factor which greatly influences the final characteriscs of concrete and performance (cracking, resistance and wear and tear). Concrete temperature is directly related to the development of strength and fresh concrete can be damaged when exposed to very low or very high temperatures.

Key factors to control during the pouring of concrete related with temperature:

· Warm weather affects speed limits

evaporaon

· Cold weather inhibits the hydraon process

Optris' CSmicro LT is equipped with an innovave, miniaturised stainless steel measuring head, the opmally suited for installaon in limited spaces. Its small size and its temperature resistance up to 120°C make the mechanic integraon of the measuring head especially cost-efficient.

The intelligent LED display works oponally as alarm signal, target support, self-diagnosis or temperature-code display. The placement of electronic components within the cable allows for a high temperature resistance of the measuring head. It measures temperature in the range of -40°C to 1,030°C; the spectral range is 8 to 14 µm and the response me is 30 ms - 999 s. The unit can be opmally installed on cement pumps, mixer trucks and cement silos.

Infrared camera Optris PI 400

Optris' PI 400 infrared camera is the smallest thermographic camera in its class. Being equipped with a measurement speed of 80 Hz and an opcal resoluon of 382 x 288

The Optris PI 400 is employed for a variety of tasks in industry. The real-me thermographic images prove especially valuable for surveillance and quality assurance in the , automotivesector plascs, and in the semi-conductor as well as photovoltaic industries.

Due to this type of thermographic cameras' high resoluon and the reacon speed, surveillance and measuring of manufacturing processes that include moving objects poses no problem. Possible areas of applicaon are process automaon of measurement in rotary kilns or measurement of large amounts on conveyor belts during batch processes.

The IR camera also plays an important role in medical diagnosis and prevenon where it detects the slightest of temperature differences. It can even highlight veins under the skin due to its brilliant opcal resoluon of up to 40 mK.

Important Specificaons

· Temperature range: -20°C to 900°C

3D Printing and the Mining Industry – The Age of Innovation

A decline in producvity in the mining industry over the past decade means industry leaders have been forced to look into an overhaul of exisng processes as tradional methods are found wanng in terms of efficiency and cost. Use of technology is one proposed soluon, but it will be innovaon that will make a marked difference in streamlining the mining industry. With 3D prinng (3DP) at the forefront of tech development, it is somewhat unsurprising that proposed usages of 3DP seem set to revoluonise supply chain operaons in the mining industry

WHAT IS 3DP?

3DP is an addive process whereby layers of raw materials are successively laid down to create a tangible object from a digital model. A digital image is looked at as thousands of layers, which are then recreated by printers. In the last decade, 3DP has grown enormously and is now ulised in the medical, automove, and aerospace industries to name a few. Rapid prototyping and rapid manufacturing have won the minds

of industry and, with numerous projected advantages, stand to change the face of producon as we know it. If 3DP evolves as ancipated, its potenal will be rather unrestricted in terms of materials used, scale, strength, and advancement of design.

OUT WITH THE OLD

As it stands, the mining industry is a sector plagued by the demands of high outputs and efficiency weighed against the high cost of downme and the conngencies made for same. These conngencies include the high cost of material inputs, excess inventory and associated warehousing and storage costs onsite, or logiscal costs of urgently transporng parts when operaons have come to a standsll.

Mining operaons rely heavily on original equipment manufacturers to produce precision-engineered parts. This, oen at great cost. It is against this backdrop that industry leaders are tasked with finding soluons that will have the praccal effect of reducing costs, opmising extracon of products, and eliminang unnecessary me

IN WITH THE NEW: HOW CAN 3DP MAKE A DIFFERENCE?

As with all evolving technologies, 3DP will have to prove it can produce high quality and precision-manufactured items out of mulple materials in order to withstand the rigorous demands of the mining industry. This will also have to be done in situ in some remote and unforgiving environments if 3DP is to be chosen over tradional manufacturing –something technology observers believe to be aainable in the next five to ten years. However, proposed adaptaons of 3DP in the mining industry claim to counteract the problems associated with tradional manufacturing methods.

“Mining operators should not put off experimenng with various applicaons of 3DP in their facilies. Developing knowledge and skills, and tesng the impact these technologies can have on their current operaonal strategies, will certainly stand them in good stead in the future.” says David

Parts failures and maintenance

Where downme is related to parts failures, 3DP offers a facility to produce parts on-site and on-demand, allowing for effecve insourcing of parts as and when they are needed. With access to a digital spare parts library and the requisite prinng technology, the remoteness of a site becomes inconsequenal and the high cost and environmental impact of transportaon and warehousing of inventory is drascally reduced. Furthermore, the raw materials used for 3DP are usually in powder form and are thus easier to transport and store. A selfsustaining picture emerges where the operaon itself is responsible for idenfying an equipment failure and prinng the soluon.

3DP also allows designs to be customised to suit the needs of a parcular operaon. This comes off the back of the ease with which 3DP can be used to replicate an item from a digital copy on-site to suit the operaon's

unique requirements. Predicve maintenance has also been proposed whereby a printer could be aached to equipment to fix components, increasing the life span of that component and addressing wear and tear

Sustainability

3DP addresses many quesons of sustainability that have become so topical of late. Not only would transportaon costs be reduced as alluded to above, but evoluon of the technology could make the designs themselves, more energy and fuel efficient. Unlike tradional manufacturing where raw materials are subtracted resulng in waste, the process of addive manufacturing in itself sees reduced waste in terms of energy used for producon and that of raw materials. It is also foreseen that used or faulty parts can be recycled allowing for the re-use of their raw materials further adding to the sustainability of 3DP

Innovation

Simplificaon across the supply chain

The proposals made in terms of 3DP will mean simultaneous changes to the supply chain operaons of the mines using the technology. These changes to the point of manufacture, inventory, equipment, labour, transportaon, and products stand to be significantly simplified, seeing a far more efficient use of financial and material resources in future. As the complexity of the exisng supply chains gives way to true ondemand in-sourcing of parts, operaons strategies and policies would need to be adapted in order to ensure effecveness.

THE WAY OF THE FUTURE

In the coming years, we are bound to see 3DP disseminated and normalised in our daily lives, but not before it radically redefines various stages of producon and manufacturing. In the mining industry, where the focus is output and producvity, 3DP stands to hold the answer to driving efficiency and creang mining-specific soluons in a largely sustainable manner
