Which of the following signifies that a structure is equipped with the necessary fire protection systems?

A structure equipped with the necessary fire protection systems needs to include various measures that collectively enhance safety and compliance with fire codes. Fire alarm systems, sprinkler systems, and emergency lighting each play a critical role in comprehensive fire protection.

Fire alarm systems are essential for detecting smoke or fire and alerting occupants, allowing for timely evacuation and intervention. They are typically the first line of defense in fire safety.

Sprinkler systems provide active fire suppression. When a fire is detected, sprinklers can automatically release water to control or extinguish the flames, significantly reducing the potential for extensive damage and the risk to life.

Emergency lighting is crucial for guiding occupants safely out of the building during a fire or other emergency. These lights illuminate exit paths in case the primary power is lost, helping ensure that everyone can evacuate safely.

Each of these components supports a robust fire protection strategy, highlighting the importance of an integrated approach. Therefore, the correct answer encompasses all of these systems, as a well-equipped structure must incorporate fire alarms, sprinklers, and emergency lighting for effective fire protection.
