What color in the NFPA system represents flammability?

In the National Fire Protection Association (NFPA) labeling system, the color red is specifically designated to indicate flammability hazards. This color-coding is part of a broader hazard identification system that utilizes a color-coded diamond shape to convey information about various hazards associated with chemicals.

In the NFPA system, the four diamonds represent different types of hazards: health, flammability, reactivity, and specific hazards. Red, being the color for flammability, signals that the material can catch fire easily and poses a risk of fire-related incidents. This is crucial information for employees handling chemicals, as it helps them understand the potential risks and the need for appropriate safety measures, such as proper storage away from ignition sources, using appropriate personal protective equipment, and understanding fire emergency procedures.

Understanding the meaning of these colors is essential for workplace safety and compliance with OSHA's Hazard Communication Standard, which requires that employees be informed about the hazards of chemicals they may encounter on the job. Therefore, recognizing red as the color representing flammability is vital for ensuring that employees can make informed decisions regarding safety practices in relation to flammable materials.
