contents may 2018 On March 15, a worker dragging his foot along a factory floor sparked an explosion at a Texas chemical plant that killed one and injured another two. Fears of further explosions and toxic chemical fumes prevented fire crews from battling the ensuing blaze and a large part of the Tri-Chem Industries plant in Cresson, about 80 kilometers southwest of Dallas, burned to the ground.

With the plant still ablaze and a toxic haze hanging over the area, the Texas Commission on Environmental Quality, the state agency responsible for coordinating the cleanup, declined to produce a list of the plant’s on-site chemicals, telling a reporter to file a public information request.

In recent years, Texas leaders have made it increasingly difficult for the public to find out about the chemicals manufactured and stored at such plants. After a fertiliser plant explosion in the city of West, Texas, killed 15 people in 2013, Greg Abbott, who was then attorney general and is now governor, ruled that state

agencies could withhold information about hazardous chemicals because of “ongoing terroristic activity.”

This happened in Cresson as well as in Houston last August when Hurricane Harvey came to call and flooded the Arkema chemical plant, also covering a whole neighbourhood in poisonous fumes that local authorities refused to identify.

The Hazardex 2018 Event saw a strong conference programme focused on cybersecurity, with the Awards ceremony another highlight

So, the official message is: we can’t tell you what poisons you’re breathing right now as, if we did, the terrorists would win.

But terrorists didn’t blow up an entire town - an unregulated fertiliser plant did.

After each of these incidents the number of people claiming their health has been wrecked by toxic fumes rises higher. It seems likely that, if this absurd situation continues, deregulation will cause more casualties across the country than terrorists ever will. …Alan Franck, Editor, Hazardex

cranes are used to move workers and supplies from the Gulf up to the decks of the platforms.

More than 50 inspectors conducted surprise inspections on about 40 offshore platforms and drilling rigs, said Jason Mathews, the head of offshore safety management for the Gulf of Mexico at BSEE. The results were still being compiled, he said, but the inspectors found serious problems, including some that were potentially life threatening.

The Interior Department and its offshore safety bureau have been under a spotlight since the agency was ordered by President Trump to re-evaluate regulations enacted during the Obama administration.

These were introduced in the aftermath of the Deepwater Horizon accident in 2010, which killed 11 offshore workers

Interior Secretary Ryan Zinke had discussed plans for the inspection push this month after the safety bureau issued an alert to offshore oil and gas operators in the Gulf. It warned about a series of

The New York Times reported on March 10 that several of the independent companies seeking a lightening of the regulatory burden had been cited for workplace safety violations in recent years at a rate much higher than the industry average.

Interior Department records released to the NYT show the rate of lift-related offshore accidents last year increased by more than 4%, reaching the second-highest annual level in the past decade. On average, there was one incident for every 13.5 offshore platforms or drilling rigs, according to agency data.

the Drilling Safety Rule and the Safety and Environmental Management Systems Rule.

The SEMS approach rightly moves operators toward a performance-based safety approach, allowing the government, industry and independent third parties to focus on improving safety outcomes.

There have also been allegations that the Trump administration’s appointment of Scott Angelle as BSEE Director could lead to conflicts of interest, given his close links to the oil and gas sector.

Angelle rejected the criticism as unfounded, said his agency was committed to safe operations in the Gulf and that the regulatory changes would remove a burden on companies while maintaining standards.

is to propose revisions that could potentially reduce burdens on operators without impacting safety and protections of the environment. Our changes will never reduce safety, and will in some cases improve safety.

Secretary Zinke announced this month that a risk-based program was formally in place, but the NYT says questions remain about the agency’s commitment to safety.

Last month, a group of 19 Senate Democrats wrote to Zinke questioning why the agency had issued a stop-work order for a study by the National Academy of Sciences that was looking at ways to reduce offshore accidents.

In late December, BSEE sent the White House a proposal to overhaul the Obama well-control

“We are also strengthening our inspection program by implementing risk-based process that focus our efforts on potential safety problems. I am confident that we will be able to achieve the goal of integrating a risk-based

“Our agency enforces dozens of regulations, but we are currently seeking public input on changes to one: the Production Safety Systems Rule. Enacted in late 2016, this regulation is not related to the Deepwater Horizon incident. The changes we propose are common sense - reducing unnecessary notifications, clarifying when operators must provide documentation, and specifying that safety and pollution prevention equipment that meets required industry standards have achieved third-party verification. We propose to codify 17 updated standards so they bear the force of law as another sign of our commitment to safety. We are examining other rules, but have not reached the publiccomment phase.

of the Gulf.

Approximately 240 platforms in the shallow waters of the Gulf, serving over 2,000 oil and gas wells as of last year, are listed by the Interior Department as “idle iron.” This means that they are severely damaged, not operating and no longer economically viable, and that they pose environmental and safety hazards.

Most of these platforms are controlled by smaller operators.

One abandoned well, formerly operated by a now-bankrupt company, has been leaking oil for 10 years and is considered to be the second worst source of US oil pollution after the Deepwater Horizon incident.

The rule changes include proposals to ease the burden of set-aside payments by operators to pay for the decommissioning and removal of this “idle iron”.

The Gulf generates 97% of offshore oil in the United States, about 18% of the country’s crude oil and $2.8 billion a year in royalty and lease payments to the federal government. In 2017, the Gulf produced a record 1.65 million barrels a day.

The format of a DS usually follows the pattern of an introduction section, providing some background as to why the DS has been created, followed by a discrete Question and a related Answer.

For example, DS 2017/01 was published in June last year, following a proposal from the convenor of one of the MTs, and the

As soon as more than between ten and fifteen terminals are included in a single enclosure, it is necessary to apply a de-rating to the individual terminals in order to control temperatures. This relates not only to the heat produced by the current passing through the terminals, but also the heat produced by the current in the enclosed wiring. In large boxes with many terminals, the rating of the

QUESTION: In arrangements where there is a necessity to de-rate terminals (typically when an enclosure contains more than 10 to 15 terminals) is it necessary to indicate this de-rating in the information provided as part of the certificate?

IEC 60079-0 contains the requirement in 6.1 b) that the equipment should comply with the normal industrial standards for the application, in addition to the specific Ex requirements of the IEC 60079 series. Such industrial standards would be presumed to include a requirement that the rating of the equipment is marked.

Its furnaces are to be equipped with low NOx burners and will be controlled via selective catalytic reduction (SCR).

One 1.5 million tonnes per year ethylene manufacturing line and two gas phase polyethylene manufacturing lines with an output capacity of 550,000t per year will also be part of the facility. In addition, one 500,000t per year slurry technology polyethylene manufacturing line will be installed.

The petrochemical complex will feature facilities to facilitate the handling of polyethylene pellet blending, handling, storage and load-out processes.

These facilities include one recovery oil storage tank, one spent caustic storage tank, two equalisation wastewater storage tanks, and one light gasoline storage tank.

Two hexane storage tanks and two pyrolysis fuel oil storage tanks will also be built, along with a variety of miscellaneous storage tanks.

PTT said the proposal included tax credits for job creation, workforce training and infrastructure improvement grants, and local tax credits.

Other than Shell, Thailand-based PTT Global Chemical is also considering building an ethane cracker plant in the area, according to local sources, on the site of a now-demolished coal-fired power plant along the Ohio River in Belmont County, Ohio.

Because of the low cost of US ethane, the cost advantage of plastic made in the United States is significant, compared with Europe or Asia.

investments nationwide as a direct result of shale gas - adding more than 50,000 permanent jobs to a workforce of around 800,000.

One of the conclusions of the International Energy Agency’s (IEA) latest five-year forecast, published in March 2018, is that the rise in the use of ethane and other shale-derived feedstocks will affect traditional refineries.

World oil demand is expected to rise by 6.9 million barrels per day (bpd) by 2023, with a quarter of this growth coming from demand for petrochemical feedstocks ethane and naphtha. “Global economic growth is lifting more people into the middle class in developing countries and higher incomes mean sharply rising demand for consumer goods and services,” the IEA said.

“A large group of chemicals derived from oil and natural gas are crucial to the manufacture of many products that satisfy this rising demand,” it added.

Naphtha is made by oil refineries processing crude, but other petrochemical feedstocks - ethane or liquefied petroleum gas (LPG) are processed outside traditional oil refineries.

“Ethane, liquefied petroleum gases and naphtha, pose a bigger threat to the refiners’ market share than electric vehicles and gas-powered transportation combined,” the IEA said, estimating refiners would see just 4.8 million bpd of the demand growth to 2023, missing out on 30% of it.

The boom in US shale gas has dramatically expanded the availability of ethane, and a string of new projects are underway to process it. In total, the world is expected to add 1.4 million bpd in new petrochemical-producing steam crackers to 2023, the IEA said.

Demand for ethane will expand at the fastest pace in the next five years, rising by 885,000 bpd, followed by naphtha with growth of 495,000 bpd and LPG with growth of 40,000 bpd, it forecast.

Remember, investigation teams are human too and as such subject to HOFs. Investigation methods, training and support from the organisation are all important factors in enabling an investigation team to do a good job.

There are no perfect methods out there, and none that fully integrate human factors.

he 2017 edition of Petrotechnics’ process safety and risk management

(PSM) survey of senior leaders in the fields of process safety, asset integrity, and operational risk management in the hydrocarbon industry produced some interesting and occasionally startling insights into the state of operational risk and safety management.

The survey indicates important gaps in organisations’ ability to develop a single, shared view of the operational reality

evidence from the 2017 survey indicates that companies do not have readily accessible and carefully structured plans in place to achieve that goal. In fact, 61 per cent believe companies do not have well-defined safety performance measures, including leading and lagging safety indicators.

believe that process safety is not always fully incorporated within an organisation’s operational excellence strategy.

Simon Jones, head of professional services at Petrotechnics shares some of the survey results below.

A key component in operational excellence The connection between process safety and operational excellence is increasingly recognised. By operational excellence, we mean the pursuit of world-class performance that is delivered by enabling everyone within the organisation to consistently make the most effective operational decisions, taking into account a fully integrated picture of the risk, cost and productivity on operational reality.

www.hazardexonthenet.net

The top driver for improving safety performance was, not surprisingly, reducing operational and major accident hazard (MAH) risk – with 71 per cent of survey participants giving this as one of their drivers.

However, despite the importance placed on reducing MAH risk, 57 per cent of the survey’s respondents said companies do not always have a defined roadmap in place for advancing safety performance.

Although advancing safety performance and risk reduction is almost always a stated goal in company literature and annual reports,

performance and reducing operational costs.

Building a safety culture When asked to rate the factors with the greatest impact on PSM, organisational culture came top of the list – cited by 86 per cent of respondents. It was followed by maintenance and internal procedures (76 per cent each). However, 61 per cent also said that developing a safety culture was a challenge to delivering effective PSM – followed by 57 per cent who said leadership support was a challenge.

Digging a little further into the role of leadership and culture, the survey showed that although corporate board members often say that safety is their highest

Together this information suggests that process safety and frontline operations must be better connected, and the relationship between the two better understood.

They also add evidence to the inherent contradictions between safety culture and safety ambitions previously noted. This is confirmed by 70 per cent of respondents

Operators need to ensure that everyone across the business understands and manages risk against the same criteria — and has a practical understanding of how their decisions directly or indirectly influence the risk picture.

who acknowledge that there are gaps between the intent of process safety planning and what actually happens on the plant or asset.

The majority of respondents (65 per cent) also felt that the C-suite has little to no understanding of the health of process safety barriers and their importance. That said, the majority (51 per cent) also felt that the C-suite is responsible for understanding where there is risk, but not for measuring and evaluating its impact – or for managing and mitigating its impact.

Perhaps more telling are the responsibilities attributed to frontline staff and functional heads respectively. The majority believe frontline staff – including shift supervisors, operations

Recognising the potential sources of risk, and how they can accumulate, is a key challenge that requires a “common currency” approach to managing the disparate sources of data. In this way they can construct leading indicators

This gets to the heart of the PSM challenge.

There is a well-established body of mature engineering science around process safety that defines how to design and operate plants to keep assets and people secure, to keep process fluids in pipes, and to stop loss of primary containment escalating into a major accident. However despite the specifications arising from this body of knowledge, once the facility is built and

pressure when maintaining operations.

Location: Perth, Australia Process Safety is at the heart of what we do and IChemE is pleased to announce that in June 2018, the globally recognised process safety conference, Hazards Australasia will return to Perth and be held for the fourth time.

Since the inaugural Hazards Australasia in 2013, commodity pricing is still under great pressure in the global markets, and this means businesses continue to face

We are still seeing companies reduce employee numbers and strive to increase production at the same time. This has resulted in a need for those remaining and the businesses to be more resilient. We need to think about how we will not just maintain the status quo, but build resilience in our operations, including reviewing capabilities and responsibilities to ensure we can adequately respond to changing demands.

knowledge and competence, engineering and design, systems and procedures, assurance, human factors and culture are fundamental to managing process safety.

You will see these topics reflected across all themes of the conference. www.icheme.org/events/conferences/

IChemE recognises that leadership across

New control panel with built-in SD interface

Han® M23 Power connector from Harting

The Schmersal Group is extending its range of control panels with the new BDF 200-SD model. This product variant now has a built-in SD interface. The BDF 200-SD is also fitted with an EMERGENCY STOP function with electronic OSSD outputs and can be fitted with up to three operational command and alarm devices, such as illuminated push-buttons, illuminated alarms, selector switches and key switches.

Using the built-in SD interface, the non-safe diagnostic signals from the command and alarm devices can be transferred via an SD gateway to the controller. In the safety circuit, different electronic safety switchgear devices, such as sensors and interlocks, can easily be connected in series using the BDF 200-SD.

The Han® M23 Power from HARTING is a new hybrid industrial connector that combines the capability to transmit both power and signals with a high degree of environmental protection.

The new connector extends the Han® M23 series by allowing the industrial lifelines of signal and power to be fully supplied from a single device.

The field of application includes drive technology as well as any areas with increased demands on vibration safety and protection against dust and water as well as other external mechanical influences. Built-in shielding also offers additional protection against electromagnetic interference.

The robust housing of the Han® M23 Power meets IP protection classes 67 and 69K in the closed position, making it particularly suitable for harsh industrial environments.
