Read the first 6 Hazardous Substances (COSHH) flashcards as text

  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 assess and control exposure to hazardous substances in the workplace, including chemicals, dust, fumes, and biological agents.

  2. What is a Safety Data Sheet (SDS) and when should you consult one?

    Answer: A document from the substance manufacturer detailing hazards, safe handling, and emergency measures

    A Safety Data Sheet (SDS) is provided by the manufacturer or supplier of a hazardous substance. It contains 16 sections covering identification, hazards, composition, first aid, handling, storage, exposure controls, and disposal. It is essential for COSHH assessments.

  3. Which hazard symbol on a container indicates the substance is toxic?

    Answer: A skull and crossbones

    The skull and crossbones symbol (GHS06) on a red-bordered diamond indicates the substance is acutely toxic and can cause death or serious harm through ingestion, inhalation, or skin contact even in small quantities.

  4. What is the primary route of entry for construction dust into the body?

    Answer: Through inhalation into the lungs

    Inhalation is the primary route of entry for construction dust (including silica, wood, and cement dust). Fine particles can penetrate deep into the lungs, causing conditions such as silicosis, COPD, and lung cancer. This is why RPE is critical for dusty tasks.

  5. What must an employer do before any work involving a hazardous substance begins?

    Answer: Carry out a COSHH assessment to identify risks and determine control measures

    Under COSHH Regulation 6, employers must carry out a suitable and sufficient assessment of the health risks from hazardous substances before work begins. This assessment determines what control measures are needed to protect workers.

  6. Exposure to cement can cause which of the following health conditions?

    Answer: Dermatitis and severe skin burns

    Wet cement is strongly alkaline (pH 12-13) and can cause irritant contact dermatitis, allergic dermatitis (from chromium VI), and chemical burns to the skin. Prolonged contact, particularly when cement gets inside boots or gloves, can cause deep, painful burns.
