In case of accidential spillage, ventilate the area. Always call LOX by its proper name, not to confuse it with compressed air. Never use oxygen in place of compressed air for any reason. Prior to filling the converter, check safety wire and relief valve and pressure closing valve for security. Discuss the safety precautions associated with gaseous oxygen.
Gaseous oxygen is extremely hazardous when used in the presence of readily combustible materials.
Do not permit oil, grease, gasoline, kerosene, aviation fuel or any other readily combustible material to come in contact with oxygen. Only oxygen conforming to MIL-27210, Type I shall be used in aircraft gaseous oxygen systems. Exercise care that compressed oxygen does not become contaminated in anyway with hydrogen, hydrocarbon gases, or oil base liquids as a serious explosion can occurr. Oil or grease must never be allowed to come into contact with or be used in the presence of open cylinders, valves, regulators, gages or fittings. Fire or explosion can result.
