• Cryogenic liquids should be stored in the upright position. Avoid rolling containers (either vertically or horizontally), as this may cause pressure buildup and explosion. For moving cryogenic liquid cylinders, always use a specifcally designed cylinder cart. • Signage may be posted near cryogenic storage freezers, compressed gas storage ...
Chapter 29 – Safe Handling of Cryogenic Liquids
2024年1月8日 · This document addresses cryogenic safety with a primary focus on and specific examples of the inert cryogenic liquids of liquid nitrogen, liquid helium, and liquid argon. Liquid helium, liquid hydrogen and liquid oxygen present additional hazards above …
inert cryogenic liquids have been determined to describe the relative risk and appropriate corresponding control measures. These levels are outlined in Table 1.
The Use and Storage of Inert Cryogenic Liquids
This policy is intended to ensure that facilities where inert cryogenic liquids are used and stored have the proper engineering controls and postings and that university staff are provided with the knowledge and training necessary to work safely when using inert cryogenic liquids.
As cryogenic liquid transitions from a liquid to a gas it expands dramatically. For example, one liter of liquid nitrogen expands to approximately 700 liters of nitrogen gas when warmed to room temperature.

2023年1月31日 · First, gas storage rooms are characterized as either indoor rooms — a room within the interior of the health care facility itself — or outdoor areas — an outdoor enclosure that meets gas storage requirements.
Use tongs to slowly add or remove objects from cryogenic liquids. Storage: 1. Demarcate cryogen storage areas by posting a hazard warning sign (Appendix I) in the storage area. 2. Keep cryogenic liquids segregated from incompatible chemicals, and away from heat/flame. 3. Only store cryogenic liquids in containersdesigned for cryogenic liquid use.
Any room or area in which cryogenic liquids are stored, dispensed or used must display appropriate hazard warning signage – see below. Safety Code of Practice 46, part 5: Cryogenic Gases, 1stEdition, November 2009
• A thin gas barrier forms between the skin and the cryogenic liquid when it is spilled on the skin. This will protect you unless the liquid hits you under force.
