ABLE SEAMAN WORKING ALOFT/HIGH AREAS. SAFETY GEARS TO WEAR. PERMIT REQUIREMENT PRIOR WORKING ALOFT.

The term “aloft” refers to anywhere 15 feet or higher, to the point where a harness is required. This applies to Seaman working not only on the mast, but over the side of the ship as well. While a few different departments go aloft.
Wherever there is a risk of falling, it should be considered as working aloft or working at a height. Work should be carried out only if there is no other alternative. Supervision or assistance from a fellow crew member alone may not improve height safety.
Use PPE like helmet, safety belt, working rope, safety rope, safety shoes.
