HOW RELIABLE IS POST-FIRE TESTING?
When there is a fire or an explosion incident where gas is possibly involved, it is standard practice to test the operation of gas system regulators that are present and in a condition that allows them to be tested. In some cases, regulators are catastrophically destroyed and no operational testing can be performed. Yet, in other cases, a regulator that is subject to some degree of fire exposure may not be considered catastrophically destroyed. Great care should be exercised prior to concluding that a regulator which has been exposed to uncontrolled fire conditions either failed or was in a defective condition prior to the exposure.
