How is the water supply for residential sprinklers categorized according to NFPA standards?

The categorization of water supply for residential sprinklers according to NFPA standards emphasizes that single-family residences are required to have a sufficient water supply to support the operation of residential sprinkler systems. This requirement ensures that these systems can effectively mitigate the risk of fire in homes, protecting both life and property.

NFPA guidelines delineate the specifications for various types of buildings and their respective life safety systems. In the context of residential properties, having an adequate water supply is crucial, as it allows sprinklers to operate effectively in the event of a fire, leading to quicker suppression and enhancing safety for occupants. Although the other options focus on specific building types or situations, they do not reflect the general requirement for single-family residences, which is explicitly acknowledged in the NFPA standards. This inclusion reinforces the importance of fire safety measures in residential settings, ensuring that all homes are equipped to handle potential fire emergencies adequately.
