Finger injury: diver caught finger in bell door

What happened?

A diver suffered an injury when his finger got caught between the top of the bell door and the retaining latch.  The incident occurred at the end of the dive, when both divers had been recovered to the bell and were preparing for return to surface.  The dive team were attempting to close the bell door; however, the racked umbilical was stopping the door from fully closing.  Diver 1 placed his hand on top of the door and leant onto it to steady himself as he tried to reposition the umbilical.  At that point, the door moved back slightly, pinching his finger between the top of the door and the retaining latch.  He suffered a deep cut to his finger which lead to him being decompressed from the system as a precaution against possible infection.

What went wrong?

The investigation for this incident highlighted a number of contributory factors:

• Incorrectly stored umbilical interfering with the closing of the bell door;
• Lack of awareness/perception of risk;
• Lack of hazard markings on the pinch point location.

What actions were taken?  What lessons were learned?

• There needs to be a thorough check of work areas for potential pinch points, and where these cannot be removed, ensure that they are physically highlighted and identified in task risk assessments (TRAs), and communicated to all personnel during toolbox talks (TBTs);
• There was a review of equipment stowage in the bell, which resulted in the repositioning of the bell scrubber, improved stowage of rebreather and repositioning of divers’ seats within the bell.
