Sprinkler Head Too Close To Slab

Article Number

4.7

Condition

SPRINKLER HEAD TOO CLOSE TO SLAB

Acceptable Performance/Condition

Upright sprinkler head deflectors are required to be located a minimum of 25 mm and a maximum of 300 mm below the slab per NFPA standards referenced in the Code.

Warranty

One-Year - Work and Materials. Two-Year - Ontario Building Code Health and Safety Violation

Action

Sprinkler heads not meeting the acceptable performance standard shall be moved or the elevation of the sprinkler head is to be modified to provide the required clearance.

Remarks

Head spacing limitations and restrictions must be considered when relocating sprinkler heads. This includes the maximum permitted spacing between sprinklers as well as the minimum spacing requirements (minimum requirements to prevent cold soldering of adjacent sprinkler heads). The hydraulic design of the sprinkler heads must also be considered. Pipe drainage issues must be considered when lowering the elevation of a sprinkler head or sprinkler pipe in a dry pipe type sprinkler system. NFPA 13 addresses specific requirements.
