What type of hazard does the color red indicate in NFPA labels?

In NFPA (National Fire Protection Association) labels, the color red specifically indicates a flammability hazard. This coding system uses numbers and colors to provide quick visual references for the potential risks associated with various materials. A red label indicates that the material has characteristics that pose a fire hazard, which is crucial for workers to recognize to ensure their safety and the safety of those around them.

Flammability ratings are typically assigned a number from 0 (not flammable) to 4 (extremely flammable), providing a clear understanding of how easily a substance may ignite and burn under standard conditions. This emphasis on flammability is essential in promoting safe handling practices and preventing fire-related accidents in the workplace. Therefore, recognizing red as a signal for flammability allows individuals to take appropriate precautions when working with or near potentially volatile substances.
