3. HAZARDA INDENTIFICATION

This product does not contain oxygen and may cause asphyxia if released in a confined area.
Simple
Hydrocarbons can cause irritation and central nervous system depression at high concentrations.
Extremely
Flammable

EYE EFFECTS:

None anticipated as product is a gas at room temperature.

SKIN EFFECTS:

None anticipated as product is a gas at room temperature.

INGESTION EFFECTS:

Ingestion is unlikely.

INHALATION EFFECTS:

Product is relatively nontoxic. Simple hydrocarbons can irritate the eyes, mucous membranes and
respiratory system at high concentrations.
Inhalation of high concentrations may cause dizziness, disorientation, in coordination, narcosis, or
nausea or narcotic.

This product may displace oxygen if released in a confined space. Maintain oxygen levels above

19.5% at sea level to prevent asphyxiation. Effects of oxygen deficiency resulting from simple

asphyxiate may include: rapid breathing, diminished mental alertness, impaired muscular
coordination, faulty judgment, depression of all sensations, emotional instability, and fatigue. As
asphyxiation progresses, nausea, vomiting, prostration, and loss of consciousness may result,
eventually leading to convulsions, coma, and death.

Oxygen deficiency during pregnancy has produced development abnormalities in humans and
experimental animals.
