What must security guards do when they encounter hazardous conditions during their patrol?

When security guards encounter hazardous conditions during their patrol, their immediate responsibility is to report the situation to their supervisor. This action ensures that the issue is addressed appropriately and that necessary measures are taken to mitigate potential risks. Reporting allows for a coordinated response, which could include notifying emergency services or implementing safety protocols.

While avoiding the area might seem like a precaution, it does not fulfill the obligation to communicate the hazard to those who can take action. Similarly, while calling for emergency services may be necessary depending on the severity of the hazard, it should be done in conjunction with notifying a supervisor who can provide guidance on the proper protocols to follow. Continuing with their duties in the presence of hazardous conditions is not advisable, as it could put the guard and others at risk. Therefore, promptly informing a supervisor is fundamentally the right course of action to ensure safety and compliance with organizational policies.
