I can think of our experiences with “piranha solution” as an example.   As a result we’ve developed detailed procedures for our campus users – see  

Think: chemical reactions which are exothermic and/or evolve gas.

Subject: [DCHAS-L] Pressure-Generating Liquid

Last week one of our investigat ors 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 porta ble fire extinguishers standard. I have searched the federal OSHA, NIOSH and AC S Web sites with no luck. Anyone familiar with such chemicals? Thank you.
