This incident report is predicated on a security flash revealed by the Worldwide Marine Contractors Affiliation (IMCA), detailing a Misplaced Time Harm (LTI) that occurred throughout upkeep work on a capstan aboard a vessel.
What Occurred
A crew member sustained a severe hand harm throughout routine upkeep of a capstan. The incident occurred whereas the crew member and an officer have been greasing the unit. The greasing level was positioned on the underside of the capstan, requiring the crew member to work in a restricted place.
After the crew member signaled the officer to interact the capstan, the rotating movement precipitated the crew member’s hand to turn into trapped between a wire clamp beneath the capstan and the deck. The harm required medical help, and the crew member was transported ashore for hospital therapy.
Why It Occurred
The harm occurred attributable to a mix of poor tools design and unrecognized hazards. Accessing the greasing level required the crew member to lie on their again and attain right into a confined space beneath the capstan, the place visibility was restricted. The design of the grease gun inspired glove elimination, growing the chance of hand publicity.
A wire clamp on the rotating underside of the capstan—troublesome to detect—was not recognized within the danger evaluation. Regardless of a toolbox discuss and risk-based planning, the crew member’s hand entered the road of fireside, highlighting a essential failure in each design issues and hazard recognition.
Actions Taken
The wire clamp beneath the capstan was eliminated, and detachable fiberglass grating was put in close to the capstan space to reinforce security. Grease factors have been prolonged to permit entry with out inserting arms beneath rotating tools. Upkeep procedures have been revised to incorporate extra exact directions for work involving rotating equipment and to handle dangers related to line-of-fire hazards. A complete inspection was carried out throughout the vessel and fleet to determine and mitigate comparable hazards.
Classes Realized
Even with comparable tools onboard, minor design variations can create sudden hazards. Common comparability and standardization of apparatus format and entry are important.
Danger assessments should think about hidden or hard-to-see mechanical parts that might pose security threats throughout routine operations.
A assessment of 1 hazard could reveal unrelated security considerations; groups ought to stay vigilant and aware of all noticed dangers.
Accidents typically consequence from a mix of systemic and design components. Satisfactory security requires addressing each human habits and engineering controls to eradicate alternatives for hurt.
