On June 11, 2008 at the Goodyear plant in Houston, TX, a heat exchanger violently ruptured due to an over pressurization caused by the isolation of a pressure relief valve. An employee walking nearby was killed by the hurtling debris from the explosion. An understanding of the importance of these valves and their proper positioning could have prevented this incident. In this module, several types of these valves and their common components will be briefly discussed, as well as the proper mounting and installation guidelines.
