Understanding DSEAR - Risk Assessment Requirements

What is a Dangerous Substance?

When you hear the term "dangerous substance," you might think of things like gasoline or chemicals. But did you know that dangerous substances can be found in almost every workplace? These substances, when not properly controlled, can lead to fires, explosions, or other serious incidents. They include common items like solvents, paints, varnishes, flammable gases, and even dust from foodstuffs or sanding. While not everything that can catch fire is classified as dangerous, certain materials like cellular plastic foams can rapidly escalate a fire if handled improperly.

So, how do you know if your workplace is safe? Identifying dangerous substances and knowing how to handle them safely is critical. It’s not just about preventing a fire—it’s about keeping your employees, customers, and business safe from potential disaster.

What is an Explosive Atmosphere?

An explosive atmosphere occurs when a dangerous substance (gas, mist, dust, or vapour) mixes with air and has the potential to ignite or explode. While an explosion might not happen every time, when it does, the flames spread rapidly. If this occurs in a confined space, the pressure can build up and cause a devastating explosion.

Simply put, these risks are present in many workplaces, but they aren’t always easy to spot. The real danger is when these substances combine with a source of ignition, like an electrical spark or a hot surface. This is why it’s so important to assess your workplace for risks and take action to mitigate them.

When Does DSEAR Apply?

The Dangerous Substances and Explosive Atmospheres Regulations (DSEAR) apply to most work environments, especially when dangerous substances are present. If you store or use flammable materials—whether it's liquids, gases, or dust—you are likely required to follow DSEAR. This includes activities like:

• Storing and using flammable liquid-based paints and inks
• Welding with acetylene
• Handling flammable solvents in laboratories
• Storing LPG or oxygen
• Transporting flammable substances

If your business is involved in any of these activities, it's essential to conduct a thorough risk assessment. This is where professional assistance is invaluable. We can help ensure your workplace is not only compliant with the regulations but also safe from potential hazards.

Steps You Should Take

DSEAR places a legal obligation on employers to assess and manage risks associated with dangerous substances. It’s not just a one-time check—you need to continually review and update your risk assessment as things change in your workplace.

Here’s a simplified breakdown of the five key steps you need to follow:

1. Identify the hazards – Recognise the dangerous substances and how they could lead to fire, explosions, or similar incidents.
2. Determine who could be harmed – Consider employees, contractors, and the general public who could be at risk.
3. Evaluate the risks and precautions – Decide whether you can eliminate or reduce the risks by using safer alternatives or putting effective control measures in place.
4. Implement and record your findings – Document the results and ensure you have control measures, such as ventilation, fire prevention systems, and safe storage.
5. Review and update regularly – Keep your assessment current, especially if there are changes to substances or processes in your workplace.

While these steps might seem straightforward, they can quickly become complicated. You need to consider everything from how substances are stored, handled, and disposed of, to how employees are trained. Assessing risks related to dangerous substances is not just a tick-box exercise. It's about ensuring your business is fully protected from potential hazards that could lead to costly and dangerous incidents.
