How should an inspector handle an unapproved substitution of fireproofing material?

Explanation:
When a fireproofing material substitution isn’t approved, the inspector must reject it and require a path that keeps the installation in line with the project specs. This means either using an approved alternative that is specified for the job or applying patching to bring the area up to the required fire-resistance rating, and documenting the decision thoroughly. Fireproofing is specified for specific materials, thickness, density, bonding, and cure requirements because these factors determine the actual fire resistance. Substituting without approval can alter those properties and compromise safety and code compliance, so it must be reviewed and validated before proceeding. If an approved alternative exists, implement it per its approval and verify the installation meets the spec. If substitution isn’t approved, use a patching approach that restores the original performance requirements and document the patch method, material, and verification. Documentation is essential for accountability, traceability, and future inspections. Approving the substitution to save time, delaying the decision until after final inspection, or patching over with no documentation would all undermine safety and record-keeping, which is why this is the correct approach.
