Last updated: September 30, 2018

What Does Control of Substances Hazardous to Health (COSHH) Mean?

The Control of Substances Hazardous to Health (COSHH) regulations were put in place by the U.S. Health and Safety Executive in 2002.

Substances hazardous to health that fall within the regulations include chemicals, products containing chemicals, fumes, dust, vapors, mists nanotechnology, gases, and biological agents. Lead, asbestos, and radioactive substances are not covered because they have their own separate regulations.

Safeopedia Explains Control of Substances Hazardous to Health (COSHH)

A COSHH assessment focuses on the hazards and risks posed by substances in the workplace. The first step is to identify where in the workplace potential hazardous substances are located. Then determine in what way the substance is harmful to health, as well as what jobs or tasks lead to exposure. Notes of any areas of concern arising from the accident book should also be taken.
