However, the severe health hazards include developing skin or respiratory diseases, reproductive problems leading to birth effects.

Certain hazardous substances also cause fatal diseases such as cancer.

What are hazardous substances?

While some hazardous substances are obvious, such as acid or bleach, there are numerous others to be aware of. COSHH regulations outline a variety of hazardous substances, which include:

  • Gases – such as carbon dioxide, methane
  • Dust – from things such as textiles and tiny parts of soil and coal
  • Mists – from oils and water-based fluids
  • Biological agents and germs – such as bacteria, viruses, parasites, that works within laboratories, and sewage treatment
  • Liquids – such as cleaning products and pesticides

  • Vapors – such as acetone present in cleaning products and nail varnish removers
  • Nanomaterials and technology – Present in batteries, cosmetics, food products, and anti-bacterial clothing

What are Safety Data Sheets and how do I use them?

If a manufacturer produces a substance that is hazardous, they must supply you with a data sheet for the substance. The safety data sheet will give you information on the substance that is useful when making the risk assessment.

The safety data sheet will describe the hazards that the substance presents. It will also explain how to safely handle and store the chemical, and what to do in the event that an accident occurs.

Employees using chemicals or hazardous substances for work should also be provided with the safety data sheets for each. If an accident does occur, the safety data sheet should be brought along with the COSHH assessment to the hospital, if medical treatment is required

What must be included in my COSHH assessment?

There is not a set form that everyone must submit for a COSHH assessment. Risk assessments will differ depending on the hazards faced. If the substances that you are using in your own workplace are hazardous, you will require a more complex risk assessment. You should use a form that works best for you.

It should cover:

  • What the risks are
  • Who is at risk
  • What control measures are needed to prevent these risks
  • How these controls are implemented

You should also confirm that these control measures are working. If you employ more than five people, this risk assessment must be recorded.
