The yellow section of the hazmat diamond is used to represent what characteristic?

The yellow section of the hazmat diamond represents reactivity, indicating the material's potential to undergo dangerous chemical reactions under certain conditions. This section uses a numerical scale from 0 to 4, where 0 means the substance is stable under normal conditions, while higher numbers indicate increased levels of reactivity and risk. Such information is crucial for first responders and those handling hazardous materials, as it helps them take appropriate precautions and prepare for potential incidents.

The other characteristics represented on the diamond include health hazards, flammability, and special information, which are shown in different colored sections (blue for health, red for flammability, and white for any special information). Understanding the significance of each color is essential for safety procedures in handling hazardous materials.
