Which best describes the function of COSHH in dental practices?

The best description of the function of COSHH in dental practices is that it controls exposure to hazardous substances. COSHH, which stands for the Control of Substances Hazardous to Health, is a piece of legislation that requires employers to assess and manage the risks associated with hazardous substances that staff may encounter in the workplace, including dental practices.

In the context of dental practices, COSHH ensures that appropriate measures are taken to minimize the risk of exposure to substances such as dental materials, disinfectants, and other chemicals that could pose health risks to both dental professionals and patients. This includes implementing safety protocols, providing training on safe handling procedures, and ensuring proper use of personal protective equipment (PPE).

The other choices do not accurately reflect the core role of COSHH. Regular supply of dental materials pertains more to inventory management, while regulating operating hours and dictating patient treatment plans are outside the scope of COSHH's purpose, focusing instead on health and safety regulations regarding hazardous substances.
