High or Triangle Bang Bars are Best
It is important to protect the health of crewmembers on crab fishing vessels and this work illustrates the benefits of banger bars and how the height of the bang bar can further reduce risk of injury among crewmembers.
Ultimately, our results revealed that the straight high bar and triangle bar (both 24 inches tall above the sorting table) resulted in greater stability, less side bending and shoulder flexion, and lower muscle activity.
Our results showed that the right-side activity was greater than left side activity due to the direction the crew was working the pot, so changing sides at the sorting table may reduce unbalanced overuse of back and arms and therefore provide better protection from back and arm injury.
Cross training to ensure that all crew can run the block would allow crew members to rotate jobs on the deck. Swapping sides at the dump box would decrease the duration and even out the strain on muscles so both sides of the body are carrying the load rather than just on one side.
This cross training takes time but may have multiple benefits. Changing positions on deck helps reduce the risk of injury and has the potential to improve morale by having fishermen fully understand and share in all tasks.
