Which of the following is listed as a COSHH hazard?

• A. Water contamination
• B. Noise exposure
• C. Radiation exposure
• D. Hazardous to the ozone layer

Answer: (D)

COSHH hazards cover substances that can harm health in the workplace, and that includes chemicals whose effects extend to the environment and human health indirectly. Ozone-depleting substances are recognized as hazards because they damage the ozone layer, leading to increased UV exposure and associated health risks. In a COSHH context, such substances are treated as controlled hazards due to their potential to cause harm to workers and the environment. The other options relate to different regulations—noise is governed by the Control of Noise at Work Regulations, radiation by radiation protection rules, and water contamination concerns general environmental quality rather than a direct COSHH health hazard.
