Installing Dewars

Precautions

Always handle Dewars with care. Any product with a glass vacuum flask is a potential safety
hazard and should be treated with caution.
We recommend the following be observed when handling Dewars containing liquefied gases:
• Protect yourself by wearing 1) goggles (or a face shield), 2) an insulated or rubber apron,
and 3) insulated gloves.
• When pouring liquefied gases from one container to another: 1) cool the receiving
container gradually to minimize thermal shock, 2) pour the liquefied gas slowly to
prevent splashing, and 3) vent the receiving container to the atmosphere.
• Use a plastic stirring rod when stirring substances in a Dewar containing liquefied gases
(or other materials of extremely low temperature). Do not use a glass or metal stirring
rod unless it is coated with some form of protective coating.
• Do not handle heavy objects above the Dewar. If unavoidable, place a protective cover
over the Dewar's opening. If an object of sufficient weight is accidentally dropped into
the Dewar, shattering may occur.
