What color on the NFPA label indicates a reactivity hazard?

The color yellow on the NFPA (National Fire Protection Association) label specifically indicates a reactivity hazard. This labeling system is designed to quickly communicate the hazards associated with materials in a straightforward and visual manner.

In the NFPA label, the colors represent different types of hazards:

• Yellow signifies the potential hazards related to reactivity, meaning that the material can undergo violent chemical reactions under specific conditions, such as exposure to heat, light, or other chemicals.

Understanding the significance of the color coding on the NFPA label is crucial for safe handling and emergency response. The system helps emergency personnel assess the risks when dealing with hazardous materials, enabling them to take appropriate safety measures to prevent accidents or exposure.
