What Is A COSHH Assessment?

 

A COSHH assessment is a form produced for any substance people come into contact with at the workplace. The assessment is to determine whether the substance may be damaging to their health, and the COSHH acronym stands for Control of Substances Hazardous to Health.

What Substances Require A COSHH Assessment?

One key element in deciding what substances need a COSHH assessment is understanding what the regulations define as a substance. These include chemicals, liquids, fumes, vapours, dust, gases, bacteria, viruses, and even nanoparticles. Also, it must be noted that substances that we may consider safe and inert still need a COSHH assessment carried out if they are substances that people may encounter at the workplace. It is only by assessing a substance, that we find out if it poses any potential hazards, and a substance which is considered hazardous is any type of substance that can have a harmful effect on a person's health. Here's a brief description of some substance categories:

  • Chemicals: Everything is a chemical, so for this category, we are focusing on liquid or powdered substances such as dried chilli powder, powder coatings, cleaning products, adhesives, paints, bleach, and thinners.
  • Fumes: These are any fumes that employees may encounter and may include, amongst others, paint fumes, exhaust fumes, welding fumes, and smoke.
  • Vapours: Although vapours and fumes may seem the same, they are two separate substances. One of the most common vapours found within workplaces is solvent vapour, which is released from substances such as paints or adhesives.
  • Dust: Dust is a common hazardous substance found in many workplaces. It may be created from materials like wood, metal, rubber or stone. Dust is considered hazardous because it may contain microscopic droplets of liquid or solid particles that can cause health problems, particularly in the lungs.
  • Gases: Hazardous gases include carbon monoxide or chlorine, which, when exposed for a certain amount of time, can be extremely toxic. Other types of gases that would be considered hazardous include those that are flammable, toxic, or corrosive.
  • Germs (That Cause Diseases): In this instance, COSHH covers any germs that cause diseases or germs that are used within laboratories. These germs may cause diseases such as legionnaires and leptospirosis.
  • Other substances that COSHH covers include mists, nanotechnology, and biological agents.

Yet surprisingly, not all hazardous substances are covered by COSHH, and this is because some substances had their own specific regulations in place prior to the implementation of the 2002 COSHH Regulations. These include:

Carrying out COSHH assessments lets employers know which products and substances pose the potential to harm. This enables an employer to design and implement control measures, which is essential as in most work environments, people use hazardous substances every day, so procedures and control measures must be in place to prevent unnecessary injury and harm. A COSHH assessment is a lawful requirement for any business where employees come into contact with substances which may potentially cause harm or companies that create new substances in the working environment. The assessment must show how to eliminate or reduce potential harm to an acceptable level.
