What precautionary measures must be established in the HazCom program?

The correct choice highlights the need for emergency procedures in the event of a chemical accident as part of the Hazard Communication (HazCom) program. This is crucial because accidents involving hazardous chemicals can occur unexpectedly, and having established emergency procedures can significantly enhance employee safety and mitigate potential risks. The procedures provide guidelines on how to respond effectively to spills, leaks, or exposure incidents, ensuring that employees are prepared to act quickly to protect themselves and others.

While employee training sessions, formal assessments of chemical knowledge, and safety videos may contribute to overall awareness and preparedness, they do not directly address the immediate actions needed during an emergency. The focus of the HazCom program is to ensure safe handling of chemicals, and understanding the proper emergency response protocols is a fundamental aspect of that safety framework. This emphasis on preparedness minimizes the impact of unfortunate incidents and promotes a safer working environment.
