Extremely flammable gas

SECTION 2: Hazards identification

Principle Routes of Exposure

Eyes; Inhalation; Skin; Target Organs: Nervous system; Respiratory system; Inhalation: Inhalation of high methane concentrations may cause central nervous system depression with dizziness, disorientation, in-coordination, nausea, and narcosis. High concentrations may also cause cardiac sensitization resulting in irregular heartbeat and may make the individual more susceptible to cardiac effects of substances such as epinephrine and adrenaline. Skin Contact: Contact with rapidly expanding gas near the point of release may cause frostbite with redness, skin color change to gray or white, and blistering. Eye Contact: Contact with rapidly expanding gas near the point of release may cause frostbite. Ingestion: Not anticipated. Product is a gas at normal conditions.
