What does an Asterisk on an HMIS label indicate?

An asterisk on an HMIS (Hazardous Materials Identification System) label specifically indicates a chronic health risk associated with the material. This symbol serves a critical purpose in safety protocols, as it draws attention to potential health hazards that might not be immediately apparent but can develop over time with exposure. Chronic health risks include long-term health effects such as cancer, respiratory issues, or other serious conditions resulting from prolonged or repeated exposure to the hazardous substance.

In contrast, other symbols on the HMIS label denote different types of hazards. For instance, flammability risk is indicated by a separate symbol that signifies the potential for the material to catch fire, while immediate health hazards are represented distinctly to alert users about dangers that could pose immediate threats upon contact. Radioactive materials have their own specific hazard identification, which is crucial for handling these substances safely. Understanding these designations is essential for effective workplace safety and compliance with health regulations.
