NFPA 13 states miscellaneous storage on racks up to how many feet tall?

• A. 15 feet
• B. 20 feet
• C. 25 feet
• D. 30 feet

Answer: (D)

In NFPA 13, the height of miscellaneous storage placed on racks is limited to ensure the sprinkler system can still deliver adequate coverage and maintain the designed hydraulic performance. The maximum height allowed for miscellaneous rack storage is 30 feet. This height keeps the design assumptions (sprinkler type and spacing, design density, and discharge) valid for protecting the rack area; going higher would require additional protection measures such as in-rack sprinklers or a different system configuration. The other given heights are typical limits for different storage scenarios, but for miscellaneous storage on racks, 30 feet is the standard upper limit.
