• When removing the power cable, hold onto the plug and not the cable.
• Do not block the air intake or air discharge vents used by the FPSE (See pictorial
on Page 10 for locations.)
• Ultra low temperature freezers are different from home freezers in that at -86°C
frostbite can occur instantly.
• For the personal safety of freezer users, safe operating procedures are essential.
—
Never 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.
• Permeable gloves are dangerous because frozen materials can contact skin
and cause damage.
— Be especially careful that materials at low temperatures are not spilled onto
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 ULT 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.
