An apparatus and method for detecting leaks in blowout preventors provides a capsule which forms an envelope about a portion of the blowout preventor where leaks exterior to the blowout preventor might occur. The capsule preferably is formed by a plurality of curved capsule segments which abut and radially assemble about flanges of the BOP system. The capsule segments carrying mating flanges which bolt together upon assembly to secure the capsule segments about the BOP stack. The interior of the flanges provides an inner space which collects leaks which might occur. The interior space is pneumatically connected to a relay which is attached to the capsule means for responding to the occurrence of the accumulated leak within the capsule.
