Using the National Fire Protection Agency code, what color diamond represents reactivity?

In the National Fire Protection Agency (NFPA) labeling system, the color that represents reactivity is yellow. This system uses a diamond shape with different colors to indicate various hazards associated with materials. Each color on the diamond corresponds to a specific type of hazard—health (blue), flammability (red), reactivity (yellow), and special hazards (white).

The yellow section specifically indicates how reactive a substance is with other materials or under certain conditions. High reactivity can signify that the material can explode, polymerize, or undergo violent reactions under certain conditions, which is critical information for safety in handling and responding to emergencies. This understanding is essential for medical technologists and anyone involved in laboratory settings to ensure proper safety protocols are followed when working with potentially hazardous materials.
