Inspect all accessible sprinkler heads for damage, obstructions, corrosion, paint, and proper clearance from storage.

  • Are all visible sprinkler heads free of paint, corrosion, foreign material, or physical damage?
  • Are all sprinkler heads maintaining a minimum 18-inch clearance from the top of stored materials?

  • Are all alarm check valves, retard chambers, and alarm test valves in proper operating condition?
  • Are all audible and visual fire alarm notification devices in the warehouse area operational and unobstructed?
  • Is the main drain test port accessible and has a main drain test been conducted within the last 12 months?
  • Has the inspector's test valve (end-line test) been operated to confirm alarm activation within the last quarter?

Storage Height, Rack Configuration, and Clearance Compliance

Confirm that storage configurations, rack placement, and commodity types match the sprinkler system design parameters.

  • Does current storage height comply with the maximum height permitted under the sprinkler system hydraulic design?
  • Is the commodity class (Class I-IV or high-hazard) of materials stored consistent with the sprinkler system design classification?
  • Are storage racks arranged to allow water distribution from sprinklers to reach the floor level without obstruction from solid rack decking?
  • Are there any new palletized storage, rack additions, or commodity changes since the last inspection that have not been evaluated for sprinkler adequacy?
  • Is a current floor plan showing sprinkler coverage zones, valve locations, and hazard areas posted at the riser?

Dry System / Pre-Action Components (if applicable)

For warehouses with dry-pipe or pre-action systems, inspect air pressure, trip valves, and low-point drains.

  • Is this warehouse equipped with a dry-pipe or pre-action sprinkler system (vs. wet pipe)?
  • Is the air or nitrogen pressure in the dry-pipe system within the range specified on the system data plate?
  • Are all low-point drum drip drains on the dry-pipe system free of trapped water and have they been drained this quarter?
  • Is the dry-pipe valve enclosure maintained above 40°F (4°C) to prevent freezing?
  • Current dry system air pressure reading?

Documentation, Deficiencies, and Corrective Actions

Record all deficiencies found during this inspection, previous corrective action status, and required follow-up actions.

  • Are the records from the previous quarterly inspection available on-site and have all noted deficiencies been corrected?
  • Has this warehouse received a sprinkler system inspection from a licensed fire protection contractor within the last 12 months?
  • Have any impairments (e.g., system shutdowns, valve closures) occurred since the last inspection and been properly documented with an impairment tag?
  • Photo documentation of any deficiencies or areas of concern identified during today's inspection?
  • List all deficiencies identified during today's inspection with location, description, and recommended corrective action?
  • Has a copy of this completed inspection report been submitted to facility management and the AHJ (Authority Having Jurisdiction) as required?
