  1. What does COSHH stand for?

    Answer: Control of Substances Hazardous to Health

    COSHH stands for the Control of Substances Hazardous to Health Regulations 2002. These regulations require employers to control exposure to hazardous substances in the workplace to prevent ill health.

  2. How many sections does a Safety Data Sheet (SDS) contain under the REACH Regulation?

    Answer: 16 sections

    Under the UK REACH Regulation, a Safety Data Sheet must contain 16 sections covering identification, hazards, composition, first aid, fire-fighting, accidental release, handling and storage, exposure controls, physical properties, stability, toxicology, ecology, disposal, transport, regulatory information, and other information.

  3. What is the correct hierarchy of control measures under COSHH?

    Answer: Eliminate, substitute, enclose, ventilate, PPE

    The COSHH hierarchy of control is: eliminate the substance entirely, substitute with a less hazardous alternative, enclose the process, use local exhaust ventilation (LEV), and finally use PPE as a last resort. PPE should never be the first line of defence.

  4. What does the GHS skull and crossbones hazard symbol indicate?

    Answer: Acute toxicity — may be fatal or cause serious harm if inhaled, swallowed, or absorbed through the skin

    The GHS skull and crossbones symbol (GHS06) indicates acute toxicity. Substances bearing this symbol may be fatal or cause serious harm through inhalation, ingestion, or skin absorption. Workers must follow strict COSHH controls when handling such substances.

  5. Under COSHH 2002, who is responsible for carrying out a COSHH assessment on a construction site?

    Answer: The employer or self-employed person

    Under the COSHH Regulations 2002, it is the employer's (or self-employed person's) duty to carry out a suitable and sufficient assessment of the risks to health from hazardous substances and to implement appropriate control measures.

  6. What is a Workplace Exposure Limit (WEL)?

    Answer: The legal maximum concentration of a hazardous substance in workplace air, averaged over a reference period

    A Workplace Exposure Limit (WEL) is the maximum concentration of an airborne substance, averaged over a specified reference period (typically 8 hours TWA or 15-minute STEL), to which workers may be exposed. WELs are listed in HSE publication EH40.
