Cryogenic storage facilities handle liquefied gases at temperatures below -150°C, presenting unique hazards including cold burns, asphyxiation, and pressure vessel failures. Implementing robust safety practices is essential.
Operators must wear cryogenic-rated gloves, face shields, and protective clothing when handling liquefied gases. Standard PPE is insufficient for temperatures below -150°C.
Cryogenic liquids expand up to 700 times when vaporised. Enclosed spaces require continuous oxygen monitoring and forced ventilation to prevent asphyxiation hazards.
All cryogenic vessels must have properly sized pressure relief valves and vent lines. Regular inspection ensures these safety devices function correctly under emergency conditions.
Personnel must receive specialised training on cryogenic hazards, emergency shutdown procedures, and first aid for cold-related injuries.
Scheduled inspections of vacuum insulation, valve seals, instrumentation, and structural integrity prevent failures before they become dangerous.
