What does a Red Diamond in the hazard identification system indicate?

In the hazard identification system, a Red Diamond specifically indicates flammability hazards. This system, often associated with the National Fire Protection Association (NFPA) label system, uses colors and numbers to convey information about the risks associated with various materials. The Red Diamond signifies that the substance is flammable or has the potential to ignite easily when exposed to an ignition source.

Understanding that the Red Diamond relates to flammability is crucial for safety when handling, storing, or working with hazardous materials, as it informs individuals about the fire risk associated with a given substance and prompts them to take appropriate precautions to prevent fire hazards. The other colors and their respective meanings help identify different types of hazards, such as health or instability, but the Red Diamond is clearly designated for flammability risks.
