What does the color white on an NFPA label signify?

The color white on an NFPA (National Fire Protection Association) label signifies special hazards information. These special hazards can include specific dangers associated with the material that are not covered by the general categories of health, flammability, or reactivity. For example, this could be used to indicate corrosives, radiation hazards, or other unique warnings that require specific handling precautions.

The NFPA labeling system utilizes a color-coded scheme where each color represents a different type of hazard. Health hazards are indicated by blue, flammability by red, and reactivity by yellow, making it easy to identify the nature of the hazards quickly. However, the white section is specifically reserved for communicating additional risks that may not fit into the standard categories. This helps ensure that individuals handling the material are fully informed of all potential dangers.
