HazCom is about communicating chemical hazards to workers. The “Com” stands for Communication, highlighting that the focus is on sharing and conveying hazard information rather than creating a separate system or dataset. In practice, this means the standard expects chemicals to carry clear labels, other hazard information provided through Safety Data Sheets, and training so employees understand risks and how to protect themselves. The other phrased options don’t align with how the acronym is used in workplace safety: they imply a system, information, or data communication, rather than the established term Hazard Communication.
