Which color is not found on an HMIS label?

The HMIS (Hazardous Materials Identification System) label is a color-coded system used to indicate the hazards associated with chemicals. The label features four quadrants, each representing different categories of hazards.

Red signifies flammability, indicating the chemical's potential to ignite and catch fire. Blue represents health hazards, indicating the level of risk to a person’s health from exposure to the chemical. Yellow denotes reactivity, showing how reactive or unstable the chemical might be under certain conditions.

The absence of green on an HMIS label signifies that it does not correspond to any hazard category defined by this labeling system. Therefore, the correct answer is the color green, which is not part of the standardized HMIS system's hazards representation. This highlights the importance of understanding the specific color codes used in hazard communication to ensure proper handling and safety.
