Extreme Cold - Cover Eyes and Exposed Skin
Accidental contact of liquid oxygen or cold issuing gas with the skin or eyes may cause a freezing
injury similar to frostbite. Handle the liquid so that it won't splash or spill. Protect your eyes and
cover the skin where the possibility of contact with the liquid, cold pipes and cold equipment, or the
cold gas exists. Safety goggles or a face shield should be worn if liquid ejection or splashing may
occur or cold gas may issue forcefully from equipment. Clean, insulated gloves that can be easily
removed and long sleeves are recommended for arm protection. Cuffless trousers should be worn
outside boots or over the shoes to shed spilled liquid. If clothing should be splashed with liquid
oxygen or otherwise saturated with the gas, air out the clothing immediately, removing it if
possible. Such clothing will be highly flammable and easily ignited while the concentrated oxygen
remains, and should not be considered safe for at least 30 minutes.
Replacement Parts Must be Suitable for Oxygen Service
Many materials, especially some non-metallic gaskets and seals, constitute a combustion hazard
when in oxygen service, although they may be acceptable for use with other cryogenic liquids.
Make no substitutions for recommended spare parts. Also, be sure all replacement parts are
thoroughly "Cleaned For Oxygen Service" in accordance with Compressed Gas Association (CGA)
Pamphlet G-4.1 "Cleaning for Oxygen Service" or equivalent industrial cleaning specifications.
Observe Safety Codes When Locating Oxygen Equipment
Before locating oxygen equipment, become thoroughly familiar with National Fire Protection
Association (NFPA) Standard No. 50, "Bulk Oxygen Systems", and with all federal, state and local
safety codes. The NFPA Standard covers the general principles recommended for the installation
of bulk oxygen systems on industrial and institutional consumer premises.
CAUTION: When installing field fabricated piping, make certain a suitable safety valve is
installed in each section of piping between shut-off valves.
For more detailed information concerning safety precautions and safe practices to be observed when handling
cryogenic liquids consult CGA pamphlet P-12 "Handling Cryogenic Liquids" available from the Compressed
Gas Association, 1235 Jefferson Davis Highway, Arlington, Va. 22202.
