What type of hazard is indicated by the NFPA red diamond?

The NFPA (National Fire Protection Association) red diamond specifically represents flammability hazards. This designation is part of the NFPA's labeling system, which uses a color-coded diamond to communicate the hazards associated with materials. The red section of the diamond is used to indicate the degree of flammability, with a scale ranging from 0 (minimal hazard) to 4 (extreme hazard).

The emphasis on flammability serves as a crucial safety measure for first responders, workers, and others who may encounter these materials. Understanding the specific hazards indicated by the red diamond helps ensure that appropriate precautions and response measures are taken to prevent fires and protect both personnel and property.
