OR LASS EWARS
Use a plastic stirring rod when stirring substances in a Dewar containing liquefied gases (or
n
other materials of extremely low temperature). Do not use a glass or metal stirring rod unless it
has a protective coating.
Do not handle heavy objects above the Dewar. If unavoidable, place a protective cover over the
n
Dewar opening. If an object of sufficient weight is accidentally dropped into the Dewar, shat-
tering may occur.
If the Dewar has a protective mesh covering, do not remove it. This cover minimizes the risk of
n
flying particles should the Dewar be knocked over, dropped, or broken.
