Part of that label may be pictograms - a black symbol inside of a red diamond border. Each pictogram has a specific meaning to convey health, physical, and environmental hazard information for a chemical's hazard class and category.
OSHA requires the use of nine different pictograms. Since you will be working with these labels, it's important that you become familiar with the pictograms.
Flame Over Circle represents oxidizers.
Flame represents flammables, self-reactives, pyrophorics, self-heating materials, substances that emit flammable gas, and/or type B, C, D, and F organic peroxides.
Exploding Bomb is used to represent explosives, self-reactives, and type A and B organic peroxides.
Skull and Crossbones represents acutely toxic materials.
Corrosion represents skin corrosives, eye corrosives, and materials corrosive to metals.
Gas Cylinder represents gases under pressure.
Health Hazard is used to represent carcinogens, respiratory sensitizers, reproductive toxicity, target organ toxicity, mutagenicity, and aspiration toxicity.
Exclamation Mark is used for irritants, skin sensitizers, acute toxicity, narcotic effects, and respiratory tract irritants.
Environment is used for aquatic toxicity.
