What should be done if two or more systems protect the same hazard?

In a situation where two or more extinguishing systems protect the same hazard, it is critical for them to operate simultaneously. This ensures that the coverage and effectiveness of fire suppression are maximized. By having all systems function at the same time, there is redundancy in the fire protection strategy, providing a greater likelihood of successfully extinguishing a fire should it occur. Additionally, simultaneous operation can lead to a quicker and more effective response to a fire, thus minimizing potential damage.

Some systems may be designed to complement each other, for instance, a dry chemical system might be used alongside a water-based system. Operating them together ensures that the strengths of each system can be leveraged effectively, providing a comprehensive approach to fire suppression in the protected area. The coordination of multiple systems working in tandem is vital for achieving optimal safety and property protection.
