Blue

The NFPA (National Fire Protection Association) label uses a color-coded system to convey critical information regarding the hazards of chemical substances. The blue section of the NFPA label specifically represents health hazards. This part of the label provides a numerical rating from 0 to 4, with 0 indicating no hazard and 4 indicating a severe hazard or a high level of health risk associated with exposure.

Understanding the significance of the blue color is essential for those working with hazardous materials, as it helps quickly assess the potential health risks involved in handling or being exposed to various substances. Knowing that blue indicates health hazards allows individuals to take appropriate safety measures and personal protective equipment to mitigate risks during their work with hazardous materials.
