Safety Precautions
To prevent personal injury, injury to others, or damage to property,
read these safety precautions carefully before use.
Do not
•
disassemble, modify or repair. There are no user serviceable parts inside the freezer unit.
Do not
•
immerse in water or pour water on the unit.
Do not
•
put ice or liquid water directly in the freezer box, always use suitable containers.
Do not
•
use glass containers when the contents might freeze and break.
Do not
•
store flammable items such as gasoline, thinner or solvents in the freezer.
The freezer is NOT rated as an explosion-proof freezer.
Do not
•
use hard and/or sharp objects, such as knives, screwdrivers, etc. to remove any frost or ice which
has accumulated on the inside of the freezer. The inside panels are heat exchangers and can be damaged.
Do not
•
cut, change or modify the power cable.
When removing the plug, hold onto the plug and not the cord.
•
Do not
•
block the air intake or air discharge vents.
Do not
•
drop, throw or abuse the freezer.
Do not
•
operate under extreme environmental conditions, such as in a car trunk,
in very high humidity environments, in rain or other severe weather.
Do not
•
use solvents to clean the panel or the outside or inside of the freezer.
An ultra low temperature freezer is qualitatively different than a home freezer.
•
At -80º C frostbite can occur in seconds.
The user should establish and follow a protocol for safe ULT operating procedures.
•
This should include (but not limited to):
—
Never
handle samples or freezer accessories with bare hands.
—
Do not
use gloves which become brittle at ultra low temperatures.
— Nitrile and latex gloves are inadequate.
Liquid permeable gloves are dangerous because ULT liquids can contact skin and cause damage.
•
— Be especially careful that liquids at ULT are not spilled onto skin or clothing.
— Use only sample containers that have been approved or tested for ULT use.
— Some plastics shatter at ultra low temperatures. Avoid splinter hazards.
— Biological and chemical hazards are still hazardous at ULT. Always wear
—
proper protective equipment and follow appropriate isolation protocols.
— Many types of labels will fall off and/or break at ULT. Some types of ink which stick to glass
—
and/or plastic at room temperature lose adhesion at ULT.
In addition to the ULT hazards above, there are also physical hazards to consider:
•
— Be cautious when closing the lid to avoid a pinching hazard.
—
Be careful when loading the box with heavy items.
—
Always
use the handles to carry the freezer.
