COSHH, which stands for Control of Substances Hazardous to Health, is a set of regulations implemented in the United Kingdom to protect workers from exposure to hazardous substances in the workplace. The regulations require employers to control exposure to materials that can cause ill health, such as chemicals, dust, liquids, gases, and biological agents. Employers are mandated to prevent or reduce workers exposure to these hazardous substances by identifying the measures to avoid a hazard or reduce the level of risk associated with it. The COSHH regulations also require employers to conduct COSHH risk assessments to identify and control the hazards and risks from substances in the workplace. Failure to comply with COSHH regulations can result in legal consequences, including fines. It is important for employers to undergo appropriate training to fully understand what is and isnt covered by COSHH and to fulfill their responsibilities under these regulations.
