These precautions may include, proper grounding, local exhaust ventilation, keeping away from open flames and electrical ignition sources, no smoking, and the discharge of vent gases to a safe location. Closed or flame arrested hydrogen systems should be used to prevent backflow of air and resulting explosion hazards. E xtreme care should be observed when moving cryogenic storage containers. Avoid rolling them by holding the neck, as it is the main support for the inner portion of the container and is very susceptible to damage. Always use hand trucks for moving cryogenic containers.
Extreme cold can drastically alter the basic properties of many materials.
Select equipment designed for use with cryogenics.
