Which of the following is a key element of an effective hazard communication program?

Maintaining proper labeling of hazardous materials is a key element of an effective hazard communication program because it ensures that all employees are aware of the potential dangers associated with the materials they may encounter in the workplace. Labels act as a vital source of information, communicating the hazards and safe handling procedures directly to workers. This helps prevent accidents, injuries, and health issues by making it clear which substances are hazardous and how to safely work with or around them. Proper labeling complements other elements of a hazard communication program, such as safety data sheets (SDS) and employee training, and forms a comprehensive approach to workplace safety.

While providing a list of all employees, offering rewards for reporting safety concerns, and scheduling social events may contribute to a positive workplace culture, they do not directly address the core objective of informing and protecting employees from chemical hazards.
