What does a red color indicate on the NFPA label?

The red color on the NFPA (National Fire Protection Association) label specifically indicates flammability hazards. This system uses a color-coded scheme to quickly convey information about the material's hazards. The red section of the label rates the substance's capability to ignite and burn, with higher numbers indicating greater flammability risks.

For instance, a substance rated with a high number in the red section signifies that it can easily ignite at normal temperatures, representing a significant fire risk in various environments. Understanding the significance of the red color allows emergency responders and workers to assess the flammability of materials quickly and act accordingly in the event of a spill or fire. Proper recognition of these hazards is critical for maintaining safety standards in hazardous materials management and responses.
