How many spare sprinklers should be maintained on the premises for prompt replacement?

Maintaining a specific number of spare sprinklers on the premises is crucial for ensuring an efficient and prompt replacement in case of system activation or maintenance. According to NFPA 13, the standard recommends having a minimum of six spare sprinklers available. This guideline is intended to ensure that a sufficient quantity is on hand to replace any sprinkler heads that may need to be changed due to malfunction or damage, without causing significant downtime or risk to safety.

Having six spare sprinklers allows for immediate response and support for various types of heads that may be installed in a system, accommodating different styles or types as necessary, depending on the occupancy and hazard level. This proactive approach minimizes the risk associated with extended outages due to sprinkler replacement needs, enhancing the overall safety of the protected property. It reflects best practices in fire protection and property management to ensure continuity and effectiveness in safeguarding against fire hazards.
