My familiarity
with this
term:
<
/DIV>
Refers to thin
gs that are
liquid at or near room temperature but have a low boiling point and expand
to a
gas at slightly elevated temperatures - hence causing the build-up of press
ure
when stored in a sealed container.

Over simplifie

but you get the idea.

Last week one of our investigators threw me a curve ball. She had an
inquiry from an employer or consultant regarding "pressure-generating liqui
ds".
The term is new to me. I have a mental picture based on the words in the ph
rase
which may or may not be accurate. The only reference I have found so far re
gards
the old-fashioned soda acid and self-generating foam water-type extinguishe
rs in
the federal portable fire extinguishers standard. I have searched the feder
al
OSHA, NIOSH and ACS Web sites with no luck. Anyone familiar with such chemi
cals?
Thank you.
