hazard communication

A hazard communication is a structured system for conveying information about dangerous substances, conditions, and practices to persons who may be exposed. It is defined by its regulated format (labels, safety data sheets, training programs), its mandated scope (all hazardous materials within an organization or jurisdiction), and its two-way flow: upward reporting of incidents alongside downward distribution of precautions. It persists through written procedures, posted labels, documented training records, and regulatory enforcement — institutionalized in standards such as OSHA's Hazard Communication Standard (29 CFR 1910.1200) and the Globally Harmonized System (GHS).
