Pictograms 5-8

The final four pictograms are as follows:

5. Corrosion
6. Gas Cylinder
7. Health Hazard
8. Skull and Crossbones

Each indicates a different class of chemicals.

The Corrosion pictogram identifies chemicals that cause skin corrosion/burns, eye damage, or metal corrosion.

The Gas Cylinder pictogram identifies the class of chemicals called "gases under pressure," which includes compressed, liquified, dissolved, and refrigerator liquified gases.

The Health Hazard pictogram identifies a chemicals' carcinogenicity, mutagenicity, reproductive toxicity, respiratory sensitization, target organ toxicity, or aspiration toxicity.

The final pictogram, the Skull and Crossbones, identifies chemicals that can cause acute toxicity and possibly death. The HCS defines acute toxicity as "those adverse effects occurring following oral or dermal administration of a single dose of a substance, or multiple doses given within 24 hours, or an inhalation exposure of 4 hours."
