What does the color white primarily indicate regarding chemical hazards?

The color white is primarily used on chemical hazard labels to indicate contact hazards. This designation alerts individuals to the potential risks associated with direct interaction with the substance, such as skin contact or inhalation of airborne particles. It serves to highlight the need for protective measures when handling materials that could harm an individual upon contact.

While other colors correspond to different types of hazards—like blue for health hazards and red for flammable hazards—white specifically focuses on the need for caution regarding direct interactions with chemicals. Therefore, recognizing white as signifying contact hazards is crucial for ensuring safety in environments where such substances are handled.
