What is a crucial aspect to check before starting operations on a ship’s hoist?

Before commencing operations on a ship's hoist, it is essential to check the condition of safety devices. Safety devices are critical components that ensure the safe operation of the hoist and protect personnel and equipment from potential accidents or failures. These devices may include limit switches, emergency stop buttons, safety locks, and alarms that provide necessary safeguards during lifting operations.

Ensuring that safety devices are in proper working condition is vital because they serve as the last line of defense in preventing accidents. For instance, if a limit switch fails, it could result in the hoist moving uncontrollably, posing significant risks to the crew and the integrity of the cargo being handled. Regular maintenance and inspections of these devices are mandatory to ensure they function effectively and comply with safety regulations.

While checking hydraulic fluid levels, noise levels, and the branding of fine bearings are also important aspects of hoist maintenance, they do not directly address the immediate safety concerns associated with the operation of the hoist. Safety devices specifically mitigate risks during operation, making them the most crucial aspect to verify before use.
