# 153.361 Arrangements for removal of valves from venting systems having multiple relief valves.A venting system having multiple relief valves may be arranged to allow the removal of a valve (for repair, as an example) provided the venting system:(a) Has valves that are interlocked, so that the removal of a valve does not reduce the venting system relieving capacity below the minimum relieving capacity required by § 153.358; and(b) Is arranged so that cargo vapor will not escape through the opening left after a valve has been removed.[CGD 78-128, 47 FR 21208, May 17, 1982; 47 FR 27293, June 24, 1982]
