(2) They should be periodically tested in accordance with the requirements of the
19.1.3. Appropriate personal protective equipment should be provided to all
seafarers involved in these operations.
19.1.4. Seafarers should be aware that it is usual for capstans, winches, or
windlasses to be designed so as to stall or pay out before exceeding the safe working
load of the weakest part of the system. Seafarers should not tamper with such
19.2.1. Any anchor or chain showing defects should be withdrawn from service
and repaired only by properly qualified persons.

wear goggles and safety helmets for protection from dust and debris thrown from the
