NFPA 99 2026 Worksheet 10
After a final tie in on an active vacuum system, each vacuum joint shall be tested with a
BLANK leak detector or other means that will allow detectant on an active vacuum
system - answer Ultrasonic
After the final tie in each joint shall be leak tested by the source gas. New work and the
existing system at the normal operating pressure shall be leak checked with a leak
detectant that is safe for use with oxygen and does not contain - answer Ammonia
After the piping system, the blow down test shall be done. Then the installer must
perform which test? - answer Initial pressure test
Alarm panels and shutoff valves labeling shall be ____________ when modifications
are made, changing the areas serviced - answer Updated
Area alarms shall be tested to verify the warning signals for all vital life support and
critical care areas if the pressure in the piping system increases or decreases by
BLANK - answer20%
At the sample port a demand of approximated 25% load shall be created to cause the
compressors to cycle on and off continuously and the dryers to operate for the ______
period. - answer12 hour
Before the piping system is put into use, who is responsible for the ascertaining that the
gas delivered to the outlet/inlet has the proper labels and connecting fittings. -
answerFacility Authority
Breached portions of the systems subject to inspection and testing shall be confined to
only the specific altered zone or area that is downstream for pressure gases at the point
of intrusion. Where a system shall be declared breached? - answerPhysical separation
of pipeline
System component removal
Replacement or addition of system components
Category 1 facility, testing, and calibration procedures shall be established to ensure
carbon monoxide monitors are calibrated __________. - answerAnnually or more often,
if recommended by the manufacturer
