The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) first came into force in 2002 but many businesses are still falling short of the requirements. Whilst the number of breaches identified during lockdown has dropped, manufacturing companies continue to receive more than 65% of the notices issued, suggesting this is where help might be needed most.

Regulation 5 requires all employers and self-employed to assess potential risks to employees and others whose safety may be affected by the use or presence of dangerous substances in the workplace. This requires knowledge of the properties of substances, circumstances of the work, maintenance activities, effectiveness of risk reduction measures, likelihood of flammable atmospheres and presence of ignition sources, and scale of the anticipated effects.

The Health and Safety Executive (HSE) identifies dangerous substances as any substances used or present at work that could, if not properly controlled, cause harm to people from fire or explosion. Given that this includes such things as solvents, flammable paints, varnishes and dusts, as well as gases under pressure and corrosives, and the fact that manufacturing often encompasses a range of complex operations, we should not be too surprised by the attention the sector receives in relation to DSEAR.

However, Regulation 6 covering elimination or reduction of risks from dangerous substances, seems to be presenting a particular problem [1].

Compliance with Regulation 6 requires duty holders to consider the hierarchy of controls and where possible look to eliminate or reduce hazards at source before considering the use of engineering controls, administrative controls or personal protective equipment. It also calls for mitigation of detrimental effects from fire, explosion or other harmful physical effects.

In order of priority, consideration of risk control measures should include:

  • reduction of the quantity of dangerous substances to a minimum;
  • avoidance or minimisation of releases;
  • control of the release at source through means of safe isolation;
  • prevention of formation of explosive atmospheres;
  • collection and safe containment and/or removal of released substances;
  • avoidance of ignition sources and other conditions that could give rise to harmful physical effects; and
  • segregation of incompatible substances.

Whereas mitigation of detrimental effects should include consideration of:

  • number of people exposed;
  • avoidance of propagation of fires or explosions;
  • explosion pressure relief;
  • explosion suppression;
  • containment; and
  • personal protective equipment.

Completion and regular review of risk assessments can be time consuming. Couple this with registration, regular maintenance and review of the physical and procedural measures in place, it is easy to understand why some businesses lose sight of where they are in terms of compliance with the regulations.

Here are five simple questions that you can ask yourself and those around you to spot signs of non-compliance:

  • Do you know what substances you have in your workplace?
  • Do they have the potential for fire or explosion?
  • Do you understand the risks?
  • Are you aware of the latest standard for hazardous area classification?
  • Do you have appropriate measures in place and are they being maintained?

If the answer is no, or you are unsure then why not contact us to find out how we can help.
