NFPA 22-2023 PDF Download

The NFPA 22-2023 standard aims to enhance building safety by providing guidelines for water tanks that supply private fire protection systems. This standard encompasses various aspects, including the design, construction, installation, and maintenance of these tanks and related equipment.

The 2023 edition of NFPA 22 includes notable revisions to improve the standard's usability and align it with modern practices. Redundant sections have been removed to ensure clarity, and the requirements for external loads, such as wind, snow, and live loads, have been updated to reference other standards and replace outdated design approaches.

Additionally, the sizing requirements for water tanks have been amended to consider the pump suction pressure during the tank's design. The construction features of the tanks have also been modified to align with newly referenced standards and acknowledge other applicable standards.

To enhance maintainability, the standard now incorporates additional valve requirements. Moreover, to prevent cavitation in the fire pump, specific separation distances between fill lines and suction pipes have been included.

Furthermore, the NFPA 22-2023 standard includes editorial corrections, such as unit conversions, where necessary. The referenced codes and standards have also been updated to ensure compliance with the latest industry practices.
