What does the white color in the HMIS signify?

In the Hazardous Materials Identification System (HMIS), the white color is used specifically to indicate the type of personal protective equipment (PPE) that should be utilized when handling a particular hazardous material. This visual cue helps ensure that individuals who may be exposed to hazardous substances are fully aware of the necessary precautions to protect themselves from harm.

Each color in the HMIS serves a unique purpose: blue typically denotes health hazards, red signifies flammability, yellow represents reactivity, and white identifies the protective equipment required. By knowing that white correlates to PPE, workers can quickly ascertain what gear or equipment they need to wear to maintain safety when working with or around hazardous materials. This knowledge contributes to a safer working environment, aligning with the goals of training programs like Basic Orientation Plus.
