Security officers are employed by corporations and specialised security companies to protect life and property. The Security Officers' Board regulates the industry and provides a grading system for security officers. Different gradings qualify security officers for different levels of responsibility.
There is always an element of danger in security work so it is essential that the security officer is highly trained in some of the following areas of specialisation, such as:
General tasks are to monitor and authorise entrance and departure of employees, visitors and other persons to guard against theft and maintain the security of the premises, to patrol industrial or commercial premises to prevent and detect signs of intrusion and ensure security of doors, windows and gates, and to operate detecting devices to screen individuals and prevent passage of prohibited articles into restricted areas.
They may need to circulate among visitors, patrons or employees to preserve order and protect property, warn persons of rule infractions or violations, and apprehend or evict violators from the premises, using force if necessary. They answer alarms and investigate disturbances. In cases of emergency, such as fire or the presence of unauthorized persons, they call the police or fire department. Some may have to answer telephone calls to take messages, answer questions and provide information during noon-business hours or when the switchboard is closed. They monitor and adjust the controls that regulate the building systems, such as air conditioning, furnace or boiler. Some may have to escort or drive a motor vehicle to transport individuals to specified locations or to provide personal protection.
