Summary
A subsea technician was injured when trapped pressure ejected a sheared indicator rod during blowout preventer pressure testing. Previously damaged rods had remained unrepaired, and a workaround omitted their hazard. BSEE recommends considering OEM maintenance, proper work procedures, avoiding out-of-service equipment and recognising trapped pressure in job safety analyses.
