The Pipeline and Hazardous Materials Safety Administration (PHMSA) is seeking public feedback on its proposed tests for composite overwrapped pressure vessels (COPVs) with different pressure relief devices (PRDs). These tests aim to help develop better safety guidelines for COPVs, especially those transporting flammable gases, by assessing the effectiveness of PRDs under fire conditions. The agency invites comments on the proposed test setups, including the duration of bonfire tests, the adequacy of sample size, and the selection of PRDs. PHMSA also asks for input on the potential impacts of using thermal activation PRDs compared to pressure/temperature-activated ones.
Simple Explanation
PHMSA wants to know if special safety devices on containers carrying gases can keep them safe during a fire. They are asking people for ideas on how to do this testing better.
