Regulation 50. Discharge from safety valves.
The discharge from any safety valve or rupture disc fitted to an unfired pressure vessel which
contains any poisonous, noxious or inflammable substance shall be led to a position of safety.
Such discharge shall not be led to a condenser or closed receiver unless such condenser or
closed receiver is itself fitted with a safety valve or rupture disc of sufficient capacity to prevent
the pressure therein exceeding its authorised safe working pressure and the connections
between such safety valves or rupture discs, as the case may be cannot become obstructed.
