“What does that multi-color diamond near each chemical symbol represent?”

 

Have you ever noticed how this a multi color diamond near many chemical containers? And have you ever wondered what it represented? Well, it turns out that that geometric object is simply a chemical hazard diamond. A chemical safety diamond is an indicator of the types of hazards that are found in the contained chemical. The yellow diamond on the left indicates the reactivity, the red diamond on the top indicates the flammability, the blue diamond on the left indicates the toxicity, and the white diamond indicates the specific hazard. The first three use a 0-4 numbering system to indicate the danger level, 0 being the lowest and 4 being the highest, while words and symbols will be written on the bottom white diamond to attest to it’s specific danger. Manufacturers by law are required to print the diamond on each container to inform the users about the safety precautions they must make.
