According to NFPA guidelines, what are the two main components of fire suppression systems?

The two main components of fire suppression systems, as outlined by NFPA guidelines, are indeed active and passive fire protection systems. Active fire protection refers to systems that require some kind of action to control or extinguish a fire, such as sprinklers, fire extinguishers, and fire alarms. These systems actively work to detect and mitigate fire incidents.

On the other hand, passive fire protection involves materials and building designs that help contain fires and prevent their spread without any active intervention. This includes elements like fire barriers, fire-resistant walls, and structural components designed to withstand fire. By combining both active and passive measures, a comprehensive fire safety strategy is created that aims to minimize risk and enhance overall safety in buildings.

The other options presented focus on specific systems or supportive measures rather than the broader categories of fire protection, which is why they do not accurately capture the main components as defined by NFPA.
