The AHJ can also require evidence of proper installation, procedure, or use to determine acceptance. Therefore, the AHJ has to base approval on, but not limited to, compliance with applicable standards, such as those produced by NFPA, and information from listing organizations.
Note that NFPA does not approve, certify or inspect any service or product directly.
NFPA defines an AHJ as “an organization, office or individual responsible for enforcing the requirements of a code or standard, or for approving equipment, materials, an installation or a procedure.” Examples of AHJ’s include, but are not limited to, fire marshals, electrical inspectors, and insurance company representatives. The term approved is defined as something acceptable to the authority having jurisdiction (AHJ). Listing organizations, such as Underwriters Laboratories (UL) and Factory Mutual (FM) Approvals, maintain databases of listed products and services that not only help you identify which products and services are listed, but also provide you important information on how the products and services can and can’t be used. The current, 2020 edition of NFPA 25 Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, under Chapter 5 Sprinkler Systems, states “except as permitted by all antifreeze systems shall utilize listed antifreeze solutions.” (5.3.4.4).
