Testing of Foam Water Deluge Systems

Question asked by jared.stolin on Sep 20, 2015

What is the expectation for testing of foam water deluge systems as it pertains to full flow foam test and concentration testing. What I am hearing from fire protection contractors is that this test is only being done for the initial acceptance. Annual system testing usually inovles taking a foam sample and doing a water only trip/flow test.


However, NPFA 25 implies that the foam concentration test should be done annually. Concerns with this are cost of discharging the foam and removal of the foam water which is an environmental concern.


Any feedback would be appreciated.
