Security personnel may also perform access control at building entrances and vehicle gates; meaning, they ensure that employees and visitors display proper passes or identification before entering the facility. Security officers are called upon to respond to potential hazards (such as broken lights or doors, disturbances, lost persons, minor injuries, etc.) and to assist in serious emergencies (medicals, fires, crime, etc.) by securing the scene to prevent further loss or damage, summoning emergency responders to the incident, helping to redirect foot traffic to safe locations, and by documenting what happened on an incident report to give their client an idea of how to prevent similar situations from occurring. Armed security officers are frequently contracted to respond as law enforcement until a given situation at a client location is under control and/or public authorities arrive on the scene.
