Sample questions
01What does the acronym COSHH stand for?
- AControl of Safety and Health Hazards
- BControl of Substances Hazardous to Health
- CContainment of Substances Hazardous to Health
- DCare of Substances Harmful to Humans
Why: COSHH stands for Control of Substances Hazardous to Health. It is the law that requires employers to control substances that are hazardous to health in the workplace, preventing or reducing workers' exposure to such substances.
02Which of the following is NOT considered a hazardous substance under COSHH?
- ASolvent-based adhesives
- BBiological agents such as bacteria
- CCement dust
- DLoud noise from machinery
Why: Loud noise is a physical hazard, not a substance, and is therefore covered by the Control of Noise at Work Regulations 2005, not COSHH. COSHH applies to chemical substances, biological agents, dust, fumes, and similar hazardous materials.
03COSHH regulations apply to which types of hazardous substances?
- ASubstances classified as flammable, explosive or corrosive, where the hazard is immediate rather than long-term
- BAny substance that can harm health, including dust, fumes, vapours, mists, gases, and biological agents
- CManufactured chemicals supplied with a safety data sheet, but not dusts or fumes created by the work itself
- DSolid materials that release dust when cut or ground, together with any liquid chemical kept in an open container
Why: COSHH covers a wide range of hazardous substances including chemicals, products containing chemicals, fumes, dusts, vapours, mists, nanotechnology, gases, biological agents, and germs that cause diseases such as leptospirosis.
