How do you fireproof a steel structure?

To fireproof a steel structure there are many techniques that involves applying materials or methods to protect the building from weakening effects of high temperature during the fire breakout.

The main aim of fireproofing structural steel is to delay the rate at which the steel heats up thus maintaining the integrity of the building for longer period during fire and allowing more time for evacuation and firefighting efforts.

Here are some of the things to be considered when planning to fireproof a steel structure –

1. Assess the fireproofing needs: The first thing is to determine the fire resistance rating of the structure. The rating varies based on the building codes, type of occupancy and the design of the structure. The rating is expressed in terms of hours. After knowing the rating, consider the specific aspects that need protection, like beams, columns and floor assemblies.

• Choose fireproofing method: Based on the assessment, choose the appropriate fire proofing method. A dedicated service provider will help you choose the apt method. Some of the common method includes spray applied, intumescent coatings, boards, vermiculate fire boards, flexible blanket system, and concrete encasement.

• Preparation of steel surface: Next method is to prepare steel surface by removing rust, oil, grease or other materials that might interfere with the adhesion of fireproofing materials. Some fire proofing methods like intumescent coatings require a primer to make sure proper adhesion to the steel.

• Application: The service provider then applies the material and ensures uniform coverage and thickness as required for the desired fire resistance rating.

• Inspection: The reliable service providers conduct an inspection after application to make sure the fireproofing material covers all the required areas and meets specific thickness. They also regularly inspect the fireproofing material for damage or deterioration over time and fix them as needed to maintain their effectiveness.

• Compliance and documentation: It is advisable to keep the detailed records of fireproofing materials used, application methods and inspection results. Make sure the building complies with the local building codes and standards. Also ensure the fire safety engineer or the local building inspector has certified the compliance.

By following all the aforesaid steps one can effectively fireproof a steel structure and enhance its fire resistance and safety in case of fire. It is imperative to collaborate with professional fireproofing service provider who will advice you the right fireproofing method for your building and carry out the work effectively.
