2 Hazards Identification

2.1 GHS Classification

Hazard Classification Description
Gas under pressureLiquefied gas, transported and stored in pressure cylinders or ISO tanks.
Specific target organ toxicity - single exposure(Health hazards)Inhalation at high concentrations may cause central nervous system depression (narcotic effects) with dizziness, drowsiness and headache; very high concentrations may cause cardiac arrhythmia.
Flammable gas (where applicable)ASHRAE safety classification A1 (low toxicity, non-flammable); a release may form a flammable mixture in confined spaces.

Note: frostbite from liquid contact with skin or eyes is a physical cryogenic injury; GHS has no separate frostbite hazard class.
