Construction Health and Safety Technician (CHST) Practice Test 2025 - Free CHST Practice Questions and Study Guide

The correct answer identifies a resource that is not part of OSHA's chemical hazard communication protocol. OSHA's Hazard Communication Standard (HCS) emphasizes the importance of Safety Data Sheets (SDS) and appropriate labeling to communicate hazards associated with chemicals effectively.

Safety Data Sheets provide essential information about the chemical, including its properties, health effects, and precautions for safe handling. Labeling standards require that labels on containers include hazard warnings and precautionary statements to inform workers about the potential dangers. Warning signs serve as visual cues in potentially hazardous areas, further enhancing communication regarding chemical hazards.

In contrast, NIOSH’s Recommended Exposure Limits (RELs) are guidelines that suggest safe exposure levels to specific workplace contaminants. While they are valuable for informing health and safety practices, RELs are primarily research-based recommendations from NIOSH rather than a direct component of OSHA's chemical hazard communication protocol. Thus, the inclusion of this resource does not align with the core components of hazard communication established by OSHA.
