For protected facilities with under 300 sprinklers, how many spare sprinklers should be kept?

• A. 12
• B. 6
• C. 24
• D. 3

Answer: (B)

Spare sprinklers are kept on site so replacements can be made quickly if a sprinkler is damaged, corroded, or removed during maintenance or testing, without delaying service or compromising the system’s protection. For protected facilities with under 300 sprinklers, keeping six spare sprinklers is the standard practice. This amount provides enough replacements to handle several maintenance events or tests while avoiding excessive inventory for smaller systems. Larger systems typically need more spares to account for longer lead times and more frequent replacements, while a very small setup would require fewer. Ensure the spares match the installed type and rating and are stored properly in their original packaging.
