What is a COSHH assessment?

A COSHH assessment is a systematic examination of a task or process that involves using a potentially hazardous substance. A COSHH Assessment is carried out for the purpose of identifying hazardous substances you may use, whether the precautions you have taken are acceptable and what control measures are in place.

We have detailed these further below:

  • Identifying the substances that you use that are potentially hazardous (a hazard is something that has the potential to cause someone harm or ill health).
  • Deciding whether the precautions you have already taken reduces the risk of someone being harmed to an acceptable level, and if not;
  • Deciding on what further control measures you must take to prevent or control the exposure to an acceptable level.

HAZARDOUS SUBSTANCES

Hazardous substances include;

  • Substances used directly in work activities (e.g adhesives, paints, cleaning agents)
  • Substances generated during work activities (e.g fumes from soldering and welding)
  • Naturally occurring substances (e.g grain dust)
  • Biological agents such as bacteria and other micro-organisms.

Effects of Hazardous Substances Examples of the effects of hazardous substances include;

  • Skin irritation or dermatitis as a result of skin contact;
  • Asthma as a result of developing allergy to substances used at work;
  • Losing consciousness as a result of being overcome by toxic fumes;
  • Cancer, which may appear long after the exposure to the chemical that caused it;
  • Infection from bacteria and other micro-organisms (biological agents).
