—
Do not
handle samples or freezer accessories with bare hands. Be especially
careful not to spill ultra-low temperature materials onto skin or clothing.
—
Do not
use gloves that become brittle at ultra-low temperatures.
— Nitrile and latex gloves are inadequate.

skin or clothing.
•
Ultra-low temperatures may adversely impact freezer contents:
—
Do not
put ice or liquid water directly in the freezer box; always use
suitable containers.
— Use only sample containers that have been approved or tested for ultra-low
temperature use.
—
Do not
use glass containers when the contents might freeze and expand.
— Some plastics shatter at ultra-low temperatures. Avoid splinter hazards.
— Biological and chemical hazards are still hazardous at ultra-low temperatures.
Always wear proper protective equipment and follow appropriate isolation
protocols.
— Many types of labels will fall off and/or break at ultra-low temperatures. Some
types of ink which stick to glass and/or plastic at room temperature lose adhesion
at ultra-low temperature.
• In addition to the ultra-low temperature hazards above, there are also physical
hazards to consider:
— Be cautious when closing the door to avoid a pinching hazard.
— Be careful when loading the cabinet with heavy items.
