Can altering fire proofing in buildings affect insurance and fire proofing of buildings?

• A. No, Alterations Have No Impact On Insurance Or Fire Resistance.
• B. Yes, Adding Encapsulant Or Removing Fire Proofing Can Greatly Reduce The Flame Retardant Nature Of Fire Proofing.
• C. Only If The Building Is Taller Than Five Stories.
• D. It Only Affects Maintenance Schedules.

Answer: (B)

The main idea here is that fireproofing isn’t just a detail to paint or cover; it’s part of the structure’s protective system. Fireproofing keeps critical structural members from losing strength too quickly in a fire. If you alter it—by removing it, encapsulating it with material that changes its heat-transfer characteristics, or otherwise modifying it—you can reduce its ability to resist heat. That means the structure could reach failure temperatures sooner, lowering the time available to evacuate and to control the fire.

Because insurers and code officials rely on maintaining the specified fire resistance, any alteration can trigger a re-evaluation of risk. This can lead to higher insurance premiums, policy conditions, or even a withdrawal of coverage until the fire protection is restored or re-certified. In short, changing fireproofing can significantly diminish its protective performance and have direct insurance and compliance implications.
