COSHH basics

What COSHH is

The law requires you to adequately control exposure to materials in the workplace that cause ill health. This is the Control of Substances Hazardous to Health Regulations (COSHH).

Harmful substances

Many materials or substances used or created at work could harm your health. These substances could be dusts, gases or fumes that you breathe in, or liquids, gels or powders that come into contact with your eyes or skin. There could also be harmful micro-organisms[61] present that can cause infection, an allergic reaction or are toxic.

Harmful substances can be present in anything from paints and cleaners to flour dust, solder fume, blood or waste. Ill health caused by these substances used at work is preventable. Many substances can harm health but, used properly, they almost never do.

Substances not covered by COSHH

COSHH does not cover the following substances as they have their own specific regulations:

The hazards

Some substances can cause asthma or other diseases, including cancer. Many can damage the skin, and some can cause serious long-term damage to the lungs.

The effect can be immediate, such as dizziness or stinging eyes, or can take many years to develop, such as lung disease. Many of the long-term or chronic effects cannot be cured once they develop.

What you have to do

You can prevent or reduce workers exposure to hazardous substances by:

  • finding out what the health hazards are
  • deciding how to prevent harm to health (risk assessment[65])
  • providing control measures to reduce harm to health
  • making sure they are used
  • keeping all control measures in good working order
  • providing information, instruction and training for workers and others
  • providing monitoring and health surveillance[66] in appropriate cases
  • planning for emergencies
