Final answer:
If you come across a contractor on the roof without proper authorization, it is important to properly identify them and contact your supervisor to report the situation. Taking notes and submitting an incident report is necessary to maintain a record. Arresting the contractor or making them leave without involving your supervisor may not be the appropriate action.
Step-by-step explanation:
If you come across a contractor on the roof who cannot provide a work order and you have no record of their presence, the appropriate course of action is to properly identify them and contact your supervisor by radio to report the matter. This is important because it ensures the safety and security of the building and its occupants.
By contacting your supervisor, you are following the chain of command and allowing them to make a decision about how to handle the situation. They may decide to investigate further or ask the contractor to leave if they cannot provide proper authorization. It is essential to maintain a record of the incident by taking notes and submitting an incident report at the end of your shift.
Arresting the contractor for trespassing may not be necessary unless there is evidence of criminal activity or refusal to leave despite being asked. Making the contractor leave and locking the roof access without contacting your supervisor may not be the appropriate action as it may lead to misunderstandings or potential legal issues.
