That’s why we’re going to explore what COSHH means and how important COSHH training is for the health & safety of your workplace.

What does COSHH stand for?

COSHH stands for The Control of Substances Hazardous to Health. There are many types of chemicals and substances used and or generated within work activities in a wide range of industries.

From products containing chemicals to fumes, dusts, and gases, COSHH covers a range of hazardous substances. According to the HSE these substances include:

  • Dusts

  • Fumes  

  • Vapours

  • Mists

  • Gases

  • Biological agents

  • Germs that can cause disease

  • Chemicals as well as products which contain chemicals, such as cleaning products

Businesses can conduct a COSHH assessment to identify the hazards and risks from hazardous substances within the workplace. This can be done either by a competent member of staff or an external professional.

The eight principles of good control practice

The HSE has outlined eight principles to follow for the control of hazardous substances. They’re in no particular order, with each principle just as important as another:

  • Minimise emission, release and spread

  • Consider routes of exposure

  • Choose control measures proportionate to the risk

  • Choose effective control options

  • Personal protective equipment – the final control option

  • Review the effectiveness of controls

  • Provide information and training

  • New measures, new risks

One of these principles is to provide information and training for your employees. This is an important element of helping to implement control measures, protect staff from hazards, reduce risks, and keep your business compliant with COSHH regulations.

Failure to comply is a crime and could lead to a hefty fine.

The basics of COSHH training

Basic COSHH training must outline and explain the following information:

  • What hazards and risks employees face

  • The exposure limit required to protect staff

  • How to monitor exposure and the outcomes of doing so

  • Health surveillance

  • What to do if there is an accident or emergency in the workplace

Who needs to complete COSHH training?

Whether or not your employees require COSHH training will depend on their specific role. If they’re exposed to hazardous substances or products, or if they oversee the work of staff which generates hazardous substances, such as dust or gases.

COSHH training isn’t just applicable in typically “dangerous workplaces”, it can be required in places such as hair salons, bakeries, school canteens, and for cleaning roles.

Other types of substances hazardous to health:

While COSHH training is detailed and educational, it doesn’t cover all types of hazardous materials and substances.

Other relevant training courses for employees exposed to hazardous substances include:

  • Asbestos awareness training
