Safe (re)fuelling

IECEx Schemes help reduce risks

Ex or explosive atmospheres are not restricted to oil refineries, offshore oil rigs, gas plants or mines. Many other industries also operate in potentially hazardous environments: sugar refineries, flour mills, grain silos and the paper and textile sectors, to name a few. Ex risks also exist in transportation.

IECEx in China

Chinese Testing Laboratory promotes the system at major event

China has seen huge economic changes in the past three decades. The state began to reform its economy at the end of the 1970s, shifting from a state-planned to a market economy. This move gave many industry sectors free rein to develop and grow, locally and internationally. Chinese industry is now a major player in the global market. China is also the country that has the world’s largest population.

From the very big to the very small

Robotic applications in Ex environments

Potentially explosive environments are obvious terrains in which to choose to deploy robots. During the 2010 oil spill in the Gulf of Mexico, robotic submersibles were sent underwater to contain and ultimately cap the spill on the sea floor, where direct human intervention was impossible. But most robots used in Ex atmospheres don't operate in such difficult and extreme conditions.

Taming the Ex factor

Kerry McManama plays major role in IECEx development and growth

Oil and gas refining, chemical processing, coal mining, paper and textile manufacturing, grain handling and storage, sugar refining. These are very different industrial sectors that have one thing in common. They all have hazardous areas in which flammable liquids, vapours, gases or combustible dusts present a fire or explosion hazard. The use of on-site electrical equipment just adds another spark to this dangerous mix. IECEx, the IEC System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres, is globally recognized as helping companies tame hazards in Ex (explosive) areas.

LEDs for Ex

IECEx-certified lighting fixtures for hazardous areas

Offshore oil platforms, refineries, shipyards, gas and oil tankers operate 24 hours a day. Most human activities may go at a reduced pace at night but the tanker will continue to trace its route across the ocean, the rig will continue to drill or pump oil, and refineries never stop refining crude oil. Night-shift crews need powerful and reliable lighting to be able to work when it is dark. Lighting fixtures, as with any other piece of equipment or device used in hazardous areas, have to be explosion-proof.

From singing to sensing

IECEx certifies modern gas detectors and sensors

A BBC News item dated 30 December 1986 announced that more than 200 canaries still employed in UK mines were to be made gradually redundant throughout 1987. The article stated that “new electronic detectors will replace the birds because they are said to be cheaper in the long run and more effective in indicating the presence of pollutants in the air otherwise unnoticed by miners.”

Failure can lead to disaster

IECEx International Conference in Malaysia

In explosive areas, seemingly small failures can have disastrous effects. To meet the world’s ever increasing demand for energy, the oil and gas industries have built larger and more complex installations for extraction, processing and distribution, requiring increasing levels of capital investment. To protect these investments and the people working in the installations, compliance with International Standards is paramount.

Exploding silos

Staple support from IECEx

Wherever cereals are grown in large quantities it is common to see silos used to store grain. Not so common is the knowledge that in these silos, or with any of the food processing equipment likely to be found alongside them, the thin layer of dust resulting from the processing has the potential to make a farm go up in flames.

Minimizing risks

IECEx ensures the safety of personnel and equipment in fossil fuel extraction

While many countries throughout the world are integrating renewable energy sources into their energy mix, they still rely heavily on fossil fuels. According to the IEA (International Energy Agency), as primary sources of electricity generation, oil, gas and coal together account for the lion’s share (67,4%) of the world’s supply (IEA 2010).

The ultimate safeguard in Ex areas

IECEx is a trusted partner for the Ex industry

IECEx (IEC System for Certification to Standards relating to Equipment for use in Explosive Atmospheres) has continued to grow in the past year. The IECEx International Conferences – in 2012 in the UAE (United Arab Emirates), and in 2014 in Malaysia – have contributed to increase awareness and visibility in the Middle East and Asia. The IECEx Certified Persons Scheme, launched in late 2010, has really taken off since 2013, benefitting from the support of several majors in the oil and gas industry.

Containing explosions

The Ex sector can rely on IECEx testing and certification for explosion prevention

More than a century ago, the introduction of electrical apparatus for signalling and lighting in coal mines provoked many electrically-induced explosions of flammable gases and dust. Consequentially, specific types of protection were developed to prevent explosions by eliminating contact between an explosive atmosphere and an ignition source.

Fuelling safety

IECEx certification helps keep explosions or fires at bay

Anyone of us can be in close contact with Ex or explosive atmospheres. They are not restricted to oil refineries, offshore oil rigs, gas plants or mines. While many industries operate in potentially hazardous environments, risks are also present in transportation: gas station or aircraft refuelling zones fully qualify as Ex areas.

Ex aspects of food safety

How to protect food processing from explosion risks

Do you realize that your local bakery may be a potentially hazardous location? In fact any area where flour, sugar, or any other type of powder is stored or processed is a potential risk area. Your kitchen as well, if you think of it, since you’re bound to regularly use a wide variety of ingredients in powder form.

Covering all bases

Safety of electrical and non-electrical equipment in Ex areas

Miners had learnt the hard way that their jobs were fraught with risks – fire damp, methane accumulation or suspended coal dust – when electric power was introduced. All it took to ignite methane for instance was a spark emitted by a lighting fixture or a motor. And the rapid growth of the oil and gas industry in the 20th century and the numerous accidents and explosions that occurred in oil drilling operations and refineries raised awareness of the dangers facing those working in this sector.

Powering devices and equipment

Very strict constraints for batteries, their containers and battery-powered devices in Ex areas

Batteries come in all forms and shapes and are probably the most common and widespread means of energy storage. From the AA or AAA type you buy at your local supermarket to the highly-sophisticated new generation of batteries used in smart portable devices, there are millions of products on offer. Not to forget electric vehicles (EVs). To increase their capacity and minimize their size, the batteries that power them are the focus of intense research and development throughout the world.

Keeping an eye on Ex risks

Video surveillance is a key asset for the Ex industry

Closed-circuit television (CCTV) is increasingly used in locations that need constant monitoring – banks, casinos, airports, military installations or shopping malls, to name but a few. A great number of municipalities around the world have installed CCTV cameras in sensitive areas of their cities to deter criminality and monitor traffic. Many industry sectors resort to video surveillance in their manufacturing processes. And video cameras are playing a major role in the monitoring and management of explosive (Ex) areas.

Ex-proof from A to Z

IECEx issues first certificates for non-electrical equipment

The interoperation between electrical and mechanical energies has existed for a long time. In standardization and conformity assessment, the need to provide a holistic solution to cover both is vital for industry and the community. While this may have been a given for most industries, the Ex sector has, for many years, focused exclusively on electrical equipment for its standardization and conformity assessment needs. This is no longer the case.

The dynamics of success

IECEx is thriving despite the many challenges posed to the oil and gas sector

The oil and gas industry sector has faced many challenges in recent years. The severe drop in oil prices has affected companies and economies throughout the world. In parallel, the need to for developed and developing countries to tackle climate change, introduce cleaner energy sources – renewables such as solar and wind, hydro – into the mix and become more energy efficient has seen some significant results when the Paris Agreement entered into force on 4 November 2016.

Dusty business

IECEx-certified equipment key in mitigating explosion risks

Some industry sectors are automatically associated with explosive (Ex) atmospheres – oil and gas, petrochemical plants, mining and in particular coal mining. Many others won’t necessarily come to mind although the risk of fire and explosion exists and needs to be heeded. Food processing, sugar refineries, grain handling and storage, printing, paper and textile industries, sawmills, woodworking areas or waste treatment operations are all potential hazardous areas. Not to mention gas stations or aircraft refuelling and hangars.

The Ex sector turns to EVs

Ex-proof vehicles are increasingly used in hazardous areas

When the term electric vehicle (EV) comes up, it usually brings to mind electric cars and possibly buses or other means of urban transportation. Seldom do we see the mention of industrial vehicles, although they represent 60% of the global EV market. Even rarer is the mention of Ex-proof industrial EVs, which are increasingly used in hazardous areas, replacing diesel-powered vehicles.

Dealing with known unknowns – and knowns

Preparing for catastrophes and mitigating their impact

Natural and industrial or accidental disasters can take many forms and have devastating human and material consequences. Some may be forecast, others not, and there may be a range of significantly different outcomes. Standardization activities by a number of IEC technical committees (TCs) and subcommittees (SCs) may help warn of impending disasters as well as aid in assessing and mitigating their human and economic impact.

Mitigating the risks and impact of explosions

IEC Standards help reduce the number of casualties from accidental industrial explosions

Explosions in a wide range of industrial or other installations can be caused by the wrong or faulty equipment, and/or by poor operating procedures or mistakes. Risks can be significantly reduced if equipment and systems that meet IEC Standards developed by IEC Technical Committee (TC) 31: Equipment for explosive environments, are used.
