Hazard communication is a key element of basic plant safety programs. Which statement best describes its purpose?

• A. Hazard communication involves labeling and communicating chemical hazards to workers.
• B. It ensures energy isolation during maintenance.
• C. It controls wastewater pH.
• D. It trains employees in PPE.

Answer: (A)

Hazard communication is about informing workers of the chemical hazards they may encounter and giving them the information and tools to protect themselves. Its purpose is to ensure that at the point of use chemicals are labeled so hazards are visible, and the safety data sheets provide details on handling, storage, exposure risks, and emergency steps. With this information, workers can choose the right controls and protective measures and respond appropriately to spills or exposures. While energy isolation during maintenance, pH control, and PPE training are important safety practices, they address different goals. Hazard communication specifically centers on conveying chemical hazard information so workers understand and can act to stay safe.
