Chemical hazard label

|
A chemical hazard label is a pictogram applied to containers of dangerous chemical compounds to indicate the specific risk, and thus the required precautions. There are several systems of labels.
The National Fire Protection Association (NFPA) has a standard using a diamond with four colored sections each with a number indicating severity 0-4 (0 for no hazard, 4 indicates a severe hazard). The red section denotes flammability. Blue is health risks. Yellow is instability (tendency to explode). The white section denotes special hazard information
