What does NFPA 20 govern in terms of fire protection?

The National Fire Protection Association (NFPA) 20 standard specifically governs the installation of stationary pumps for fire protection. This standard outlines the requirements for the design, installation, maintenance, and operation of these pumps, which are crucial for supplying water to fire protection systems such as sprinklers and standpipes. Having clear and consistent regulations is essential to ensure the effective and reliable performance of stationary fire pumps in emergency situations, as they help maintain water flow and pressure necessary to extinguish fires.

In contrast, the other options address different aspects of fire protection: hose installation and standpipe systems are covered by other NFPA standards, while emergency exit requirements are established by codes focused on life safety, rather than fire protection systems directly. Understanding this context reinforces why NFPA 20's focus specifically on stationary pumps is vital in the broader framework of fire protection regulations.
