606 - Cryogenic Liquid Containers
- All cryogenic liquids are extremely cold. The liquids and their vapors can rapidly freeze human tissue and can cause many common materials such as carbon steel, rubber, and plastics to become brittle or even break under stress.
- Vaporization of a cryogenic liquid, except oxygen, in an enclosed area can cause an oxygen deficient atmosphere. Vaporization of liquid oxygen in an enclosed area can cause oxygen enrichment. Monitoring for oxygen is essential for worker safety.
- Handle cryogenic liquids carefully to avoid spills. Avoid contact with skin and eyes. PPE for handling cryogenic liquids includes a full-face shield over chemical goggles, loose-fitting thermal insulated or leather gloves, long sleeve shirts, and full-length cuff less pants that extend over shoes tops. Safety shoes are required for workers handling the containers.
- Refer to the SDS for specific requirements based on the cryogenic liquid.
