AP 14 - Control of Substances Hazardous To Health (COSHH)

General

  • Using chemicals or other hazardous substances at work can put people’s health at risk. ​​​​​​​ These include:

    • Skin irritation or dermatitis as a result of skin contact

    • Asthma as a result of developing an 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 has caused it

    • Infection from bacterial and other micro-organism

There are generally three main routes of exposure from hazardous substances and they are:

  • Absorption – contact through skin/eyes

  • Inhalation – breathing in

  • Ingestion – swallowing​​​​​​​

  • No substance should be used or introduced into the workplace unless it has been provided with a COSHH Assessment for the product has been completed.

  • Store the product as per the manufacturers instructions.

  • Wear the correct PPE as identified as per the COSHH assessment.

  • The storage of hazardous products is extremely important.  Advice should be taken from the Materials Safety Data Sheet (MSDS). 

  • Flammable and highly flammable materials must be stored in metal cabinets away from heat or direct sunlight.
