Oxygen
A Colorless gas, one of the main components of the air. Oxygen is necessary for the
breathing of humans and animals, oxygen deficiency is harmful to health.
Strong oxidizer, sustains combustion.
Strong oxidant. May reacts with combustible and
reducing materials (oils, solvents, etc), causing fire and
explosion hazards. Oxygen enriched atmospheres
(>22% O
2
) present a significant fire and explosion risk.
Oxygen deficiency in the air may lead to loss of
concentration, reduced coordination, fatigue. At very
reduced levels fainting and death may occur.
Breathing of oxygen at increased concentrations may
lead to hyperoxia (seizures, respiratory problems,
disorientation).
