Which of the following is a COSHH hazard?

• A. Magnetic field exposure
• B. Flammable
• C. Loud noise
• D. High temperature exposure

Answer: (B)

COSHH hazards are hazards that come from substances that can affect health. A chemical that is flammable can ignite easily, creating fire and explosion risks as well as potential health effects from vapors or exposure. That makes it a COSHH hazard because it involves a hazardous substance and the ways workers could be exposed to it. The other options describe hazards that are physical or environmental rather than hazards from substances—for example, magnetic fields are EMF/physical hazards, loud noise is a noise/ototoxic risk, and high temperature exposure is a thermal hazard. In a COSHH assessment, flammable chemicals would be controlled through proper storage, ventilation, elimination or substitution if possible, engineering controls, appropriate PPE, and clear labeling and handling procedures.
