Health
This product is a gas at normal temperature and pressure, and in ultra-low quantities, this makes
inhalation or ingestion very unlikely. No harm is expected from contact of gas to the skin and eyes,
however, liquid may cause frostbite.
Personal Safety
Information
If handling cylinders, wear gloves and OSHA approved eye and foot protection.
Inhalation
Asphyxiation. Effects are due to lack of oxygen. Moderate concentrations may cause headache,
drowsiness, dizziness, excitation, excess salivation, vomiting and unconsciousness. Lack of oxygen
can kill.
