| Safety Profile |
Human systemic effects by inhalation: cough and other pulmonary changes. Human teratogenic effects by inhalation: developmental abnormalities of the fetal cardovascular system. Mutation data reported. Not toxic as gas. In liquid form it can cause severe "burns" and tissue damage on contact with the slun due to extreme cold. An oxidant. Though itself nonflammable,it is essential to combustion. Even a slight increase in the oxygen content of the air above the normal 21% greatly increases the oxidation or burning rate (and the hazard) of many materials. Exclusion of O2 from the neighborhood of a fire is one of the principal methods of extinguishment. Avoid smoking, flames, electric sparks. Liquid O2 can explode on contact with readdy oxidizable materials, especially at high temperatures. Under the proper condltions of temperature, pressure, and reagent concentration it can react violently with acetaldehyde, acetylene, acetone, secondary alcohols (e.g., 2-propanol, 2-butanol) aluminum, Al(BH4)3, AH3, aluminumtitanium alloys, alkali metals @hum, cesium, potassium, rubidlum, sodlum, potassium), ammonia, ammonia + platinum, asphalt, ccl4, chlorinated hydrocarbons, cyanogen, barium, benzene, 1,4-benzenediol + 1-propanol, benzoic acid, Be(BH4)2, biological materials + ether, BAszBr3, B2H10, diH6, boron tribromide, boron trichloride, bromine + chlorotrifluoroethylene, butane + Ni(CO)4, carbon disulfide, carbon disulfide + mercury + anthracene, carbon monoxide, CsH, calcium, calcium hosphide, copper + hydrogen sulfide, Cl0H14, cyclohexane-l,2-done biskhenylhydrazone), cycl0℃tatetraene, dborane, diboron tetrafluoride, dimethoxymethane, dimethylketene, dimethyl sulfide, diphenyl ethylene, disilane, ethers (e.g., diethyl ether, diisopropyl ether, tetrahydro furan, dtoxane, ethyl ether), fibrous fabrics, fluorine + hydrogen, fuels, germanium, glycerol, halocarbons (e.g., l,l,l-trichloroethane, trichloroethylene, chlorotrifluoroethylene, bromotrifluoroethylene), hydrazine, hydrocarbons (e.g., 1,l-dphenylethylene, gasoline, cyclohexane, ethylene, cumene, pxylene, but-3-yne), hydrocarbons + promoters (e.g., methyl nitrate, nitromethane, ethyl nitrate, tetrafluorohydrazine), hydrogen, hydrogen sulfide, lithiated dalkylnitrosoamines, magnesium, metals, metal hydrides (e.g., sodtum hydride, uranium hydride, lithium h ydride, potassium hydride , rubidium hydride, cesium hydride, magnesium hydride), methane, methoxycycl0℃tatetraene, 4-methoxytoluene7 Ni(CO)4 + butane, nonmetal hydrides (e.g., diborane, tetraborane(lO), phosphine, pentaborane(1 l), pentaborane(9) , decaborane(l4), aluminum tetrahydroborate), oil films, organic matter, (OF2 + H20), phosphorus, phosphorus tribromide, phosphorus trifluoride, phosphorus(IⅡ) oxide, polymers [e.g., foam rubber, neoprene, polytetrafluoroethylene (teflon)], polytetrafluoroethylene + stainless steel, polyurethane, polyvinyl chloride, propylene oxide, K2O2, rhenium, trirhenium nonachloride, rubber + ozone, rubberized fabric, selenium, NaH, sodium hydroxide + tetramethyldsiloxane, strontium, tetracarbonylnickel, tetracarbonylnickel + mercury, tetrafluoroethylene, tetrafluorohydrazine, tetrasilane, titanium and alloys, trisilane, CH2Cl2, oil, paraformaldehyde, wood, charcoal. Compressed O2 is shipped in steel cylinders under hgh pressure. If these containers are broken due to shock or exposed to high temperature, an explosion and fire may result.
