Which elements are included in a comprehensive fire suppression system?

A comprehensive fire suppression system is designed specifically to prevent and extinguish fires effectively. The key components of such a system typically include extinguishers and sprinklers, which are both critical in managing and controlling fire hazards.

Extinguishers are portable devices that allow individuals to fight a small fire before it escalates, while a sprinkling system provides automatic suppression by discharging water when a fire is detected. These two elements work together to provide immediate response capabilities in case of a fire, making them essential in any fire suppression strategy.

The other options, while important in their respective contexts, do not contribute directly to the primary function of suppressing fires. Heating units and ventilation might influence fire behavior, but they do not serve as suppression systems. Security cameras and alarms are useful for safety and monitoring but do not extinguish or suppress fires themselves. Similarly, electrical wiring and plumbing pipes are essential systems within a building but are unrelated to fire suppression capabilities. Therefore, extinguishers and sprinklers stand out as critical elements in a comprehensive fire suppression system.
