Signal word

DANGER

Hazard statements

H280 - Contains gas under pressure; may explode if heated H220 - Extremely flammable gas CGA-HG04 - MAY FORM EXPLOSIVE MIXTURES WITH AIR. OSHA-H01 - MAY DISPLACE OXYGEN AND CAUSE RAPID SUFFOCATION.

Precautionary statements

P202 - Do not handle until all safety precautions have been read and understood. P260 - Do not breathe gas. P403 - Storeand use in a well ventilated place. P410+412 - Protect from sunlight. Do not expose to temperatures exceeding 50 °C/122 °F P210 - Keep away from heat/sparks/open flames/hot surfaces. No smoking P377 - Leaking gas fire: Do not extinguish unless leak can be stopped safely. P381 - Eliminate all ignition sources if safe to do so. CGA-PG05 - Use a back flow preventive device in the piping. CGA-PG06 - Close valve after each use and when empty. CGA-PG10 - Use only with equipment rated for cylinder pressure. CGA-PG12 - Do not open valve until connected to equipment prepared for use.

Principle Routes of Exposure

Target Organs Inhalation Skin; Eyes; Inhalation; Respiratory system; Central nervous system; Methane and nitrogen are simple asphyxiants. Oxygen levels should be maintained at greater than 18 molar percent at normal atmospheric pressure which is equivalent to a partial pressure of 135 mm Hg. Exposure to high concentrations of this gas mixture may exclude an adequate supply of oxygen. Effects of oxygen deficiency resulting from simple asphyxiants 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 developmental abnormalities in humans and experimental animals. 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.
