What must be done to rotating shafts, regardless of their protrusion?

Adding end caps to rotating shafts is a critical safety measure because it effectively helps prevent accidents by covering the ends of the shafts, which may be exposed during operation. This simple action reduces the risk of a worker coming into contact with the sharp edges or moving parts of the shafts, which can lead to serious injuries. End caps not only enhance safety but also can reduce the accumulation of debris and contaminants inside the shaft, promoting better performance and longevity of the equipment.

In contrast, while safety labels are important for communication of hazards, they do not physically protect workers from the dangers associated with protruding shafts. Painting bright colors may increase visibility, but it does not prevent contact or injury. Regularly checking for wear and tear is certainly a critical maintenance practice, but it does not address the immediate safety risks posed by exposed rotating shafts. Therefore, ensuring that end caps are used provides both proactive protection and contributes to a safer working environment.
