MCAA Guide to Pressure Testing Safety

Guide TO Pressure Testing Safety Guide to Pressure Testing Safety 2013, Mechanical Contractors Association of America, Inc. All rights reserved. 1 Application This Guide applies to the Pressure Testing of standard metal piping systems, excluding cast iron systems. It does not apply to: Cast iron piping systems; Fiberglass piping systems; Plastic piping systems; PVC piping systems; or CPVC piping systems. Forward MCAA receives frequent requests for information about how to safely perform Pressure Testing .

compressed when used in the systems without liquid. To get a feel for how potentially hazardous pneumatic testing can be, take a look at the following comparisons between the stored energy in piping systems, and the equivalent stored energy in Trinitrotoluene (TNT), an explosive that is the standard measure of strength for bombs.

WELDERS? B31.9 permits "interchange" of welders among contractors after they have been properly qualified by one contractor provided the welder’s new employer accepts responsibility for qualification performed by the other contractor. By interchanging qualified welders, contractors do not have to repeat the time-consuming testing of workers.
