How much should projecting shaft ends and edges not exceed in terms of their diameter?

One-quarter
One-third
One-half
Three-quarters

The correct answer is: One-half

The correct answer regarding the maximum allowable projection for shaft ends and edges is that they should not exceed one-half of their diameter. This regulation is in place to enhance safety by ensuring that any projecting parts do not pose unnecessary risks to workers. Excessive projection can become a hazard, making it easier for workers to accidentally come into contact with rotating equipment, which may lead to severe injuries. Ensuring that projections are limited to one-half of the diameter helps maintain a safer working environment. It minimizes the chances of snagging or entanglement, which is critical in preventing workplace accidents. This guideline is supported by industry standards and OSHA regulations aimed at promoting safety in construction and operational environments.
