Hazard communication in hazardous waste management primarily involves which elements?

• A. Vehicle fuel efficiency standards.
• B. Public tax reporting and audits.
• C. Labels, safety data sheets, training, and other information to protect workers and the community.
• D. Employee recruitment procedures.

Answer: (C)

Hazard communication is the system that ensures people who handle or are exposed to chemicals know the hazards and how to protect themselves. The best answer focuses on the core tools that make this possible: labels on containers so the hazard is identified at a glance; safety data sheets that provide detailed hazard information and safety measures; training that teaches workers how to handle, store, transport, and respond to spills or exposures; and other accessible information such as site procedures and safety guides. Together, these elements help prevent injuries, exposures, and environmental releases by ensuring everyone understands the risks and the correct protective actions. The other options don’t involve communicating chemical hazards or protecting people through information and training.
