As per the requirements of the IMDG code, a pressure relief valve is fitted to the top of the tank. It consists of a 2.5” BSP (65mm nominal bore), fitted with both pressure and vacuum relief facilities. The whole unit is encircled with fireproof gauze. In the event of an emergency the wire gauze prevents flammable contents from catching fire in the case of fire engulfment.
This valve is designed to relieve pressure in the tank at a setting of 4.4 bar (converts to 63.82 psi) large enough relieving air flow capacity in the case of complete fire engulfment (IMDG Code section 188.8.131.52.2). The valve is an independent safety device and should not be connected or relied upon, within the process for performing other relieving or regulating functions.
The relief valve is also fitted with a vacuum relieving spring set at 0.21 bar (converts to 3.0 psi) Once more, this is an independent safety device and should not be used or relied upon for any other function. It is merely designed to function in the event of an overvacuum situation.
