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