In an explosion in a compressor in factory, 5 persons died.
For preventing excessive pressure, atleast a safety relief valve will be used, set to release at a pressure above maximum allowable working pressure. In pressure vessels coming under SMPV rules, generally, two relief valves are used. These valves need to be tested every twelve months by competent person.
Also, the material of construction for valves shall be suitable for the service.
Regarding air compressors, we find tyre repair many shops having along the road. Poor maintenance of such equipment are a hazard to passersby.
