What precaution should be taken when working in the hoistway while someone is working above?

When working in a hoistway while someone is working above, it is crucial to ensure that proper protection measures are in place. This typically involves implementing safeguards such as barrier systems, safety nets, or other protective equipment that can help prevent falling objects from causing harm to individuals below.

This precaution emphasizes the importance of creating a safe working environment, as various hazards can arise in such situations, including tools or materials accidentally dropping from above. By having appropriate protective measures established, the risk of injury is significantly reduced, allowing both workers above and below to perform their tasks more safely.

Other choices do provide some safety considerations, but they do not encompass the comprehensive risk management that comes with having proper protective measures in place. For instance, wearing a helmet can provide some level of protection, but it is not a substitute for implementing broader safety measures that address the risks of a hoistway environment.
