BUMP GAS TESTING
BUMP TESTS:
Gas test (or “bump test”) each zone using the bump gas method
described below to ensure that the monitor is operating properly, the alarms operate, and
that each zone’s gas path is clear.
a. This procedure uses “bump gas” (dilurothane) as an inexpensive test gas.
Virtually any brand of keyboard cleaner or “canned air” (readily available at most
computer and variety stores) contains this refrigerant and is sufficient to perform a
bump test.
