Verified grounding for safety in hazardous locations

Verified grounding for safety in hazardous locations

The generation of static electricity is an inevitable by-product of day to day operations. Processes ranging from drum filling operations, to pneumatic conveying of powders, to mixing operations have the capability to generate huge amounts of static electricity.

When static electricity accumulates on plant equipment like drums, piping, vessels, trucks and flexible intermediate bulk containers there is a very real risk that a spark will be discharged. The only additional factors that will influence an ignition are whether or not a flammable/combustible atmosphere is present in the path of the spark discharge and if the energy in the spark exceeds the minimum ignition energy of the atmosphere.

The transportation of flammable products by rail, whether that be as a result of the shale driven boom in crude by rail or the transportation of chemicals from petrochemical manufacturing centres to end user markets, is still one of the most flexible and cost effective methods by which to move flammable products across the continent of North America in bulk quantities. And while this industry has a host of safety and environmental regulations to contend with, one area of safety that is often misinterpreted or misunderstood, is the ignition hazard associated with static electricity and the measures that can be put into practice to control this risk.

IEC publishes guidance for the avoidance of hazards due to static electricity

The International Electrotechnical Commission has published a new Technical Specification called IEC 60079-32-1: “Explosive atmospheres - Part 32-1: Electrostatic hazards - Guidance”. This Technical Specification is a guidance document which is the latest addition to the IEC series of 60079 “Explosive Atmospheres” standards that are designed to limit fires and explosions caused by electrical malfunctions within hazardous locations.

Protecting workers and company assets from ignitions caused by static electricity can’t be left to chance. In facilities where flammable and combustible products are processed, there’s a very high probability that static electricity is generated by the movement of gases, liquids and solids. The risks of a fire or explosion caused by a discharge of static electricity in an EX/HAZLOC area are just too significant to ignore. To emphasise its significance static electricity is identified in North American and European legislation as a potential source of ignition in potentially flammable and combustible atmospheres.

Hazop assessments, and the reports that follow on from them, are a great way of capturing and identifying processes and
practices that could lead to the ignition of flammable atmospheres through discharges of static electricity. What Hazop reports are not so great at doing is identifying what the grounding solution to eliminate the risk should look like.
