I’m reviewing the compliance of pull station covers with ADA and NFPA 72 standards. Specifically, the covers protrude about 5.2 inches from the wall(Surface Mounted), which exceeds the ADA guideline of 4 inches for objects in circulation paths. The vendor has stated that the pull station is ADA compliant for operation but not for the projection, and they mentioned that the final determination should be up to the Authority Having Jurisdiction (AHJ). Note these pull station covers are used everywhere. However clarification and an exception explanation will be good to have.
I’m looking for clarification on a few points:
I’m looking for clarification on a few points:
- Does NFPA 72 allow for the AHJ to make the final call on whether protrusions beyond the 4-inch limit are acceptable, and does it provide any guidance on how the AHJ should interpret or approve these situations?
- Does the ADA contain any specific language that suggests the AHJ has the authority to approve deviations from the 4-inch protrusion limit, or should the design strictly adhere to the 4-inch rule?
- If an exception is allowed by the AHJ, what kind of documentation or justification would be needed to support the decision?
