During a trial of fire-fighting equipment, a hose expansion joint or bellows failed. 

What happened?

The release of pressurized water hit a crewman who was standing nearby, slamming him backward and knocking him unconscious. The fire pump was shut down and help was sought. CPR was administered; subsequently the injured person was medevaced.

This incident was considered by our member to be a potential fatality. The injured person was in hospital for some weeks.

Failed hose expansion joint

What went wrong? What were the causes?

Some identified issues were:

  • There was inadequate management of significant risk.
  • There was no understanding of the life time of the expansion joint or bellows.
  • There was no installation procedure provided for this bellows by the manufacturer.
  • There was no preventive maintenance or inspection/testing of the failed equipment.

What actions were taken? What lessons were learned?

Our member drew the following lessons:

  • There had been a similar rupture of a bellows some years previously; this earlier incident was not investigated. Had it been investigated, it might have helped in preventing reoccurrence.
  • Engineering and design of critical equipment during new building should take into consideration personnel safety as well as equipment protection.
  • There needs to be a better design review of pressurised equipment, particularly where different components are in use.
