What should a sanitation worker do when they hear someone calling for help from a building?

A sanitation worker hearing someone calling for help should prioritize the safety and well-being of the individual in distress. Calling 911 is the most appropriate action because it ensures that trained professionals, equipped to handle emergencies, can respond quickly. This response is essential because emergency situations often require medical attention or police involvement, which sanitation workers are not trained to provide.

By contacting emergency services, the sanitation worker facilitates immediate help while also ensuring they do not put themselves in harm's way. This action also follows the legal and ethical obligation to report emergencies, contributing to a safe and cooperative community environment.

While trying to enter the building to assist or asking for help from coworkers could seem helpful, those actions come with risks, especially if the situation is dangerous or involves unknown factors. Ignoring the call for help is not an option as it neglects the responsibility to act in the face of potential harm to others.
