Fire Proofing and Intumescent Coatings

By dciflooringUncategorized

Fireproofing plays a critical role in protecting personnel, equipment, and infrastructure from collapse and failure in both the public and private sectors. These materials are used to maintain the integrity of structural elements, protecting them from collapse for a given amount of time when exposed to fire. Fireproofing system selection is similar to materials selection in that many factors need to be considered, including types of exposure, operating conditions, substrate, application conditions, environmental regulations, cost, time constraints, and design/fabrication considerations. When an environment is at substantial risk for fire – such as in petrochemical plants, refineries, or offshore oil and gas platforms – the incorporation of a passive fireproofing coating must be considered and implemented. These fireproofing systems are commonly used along with an appropriate corrosion-resistant primer to provide fire protection as well as corrosion resistance.

Applying Intumescent Coatings

Interior
Application is performed through a three step process.
  1. The first step of the intumescent system is the application of a compatible steel primer to the steel substrate.
  2. Next, the intumescent base coat is applied to the primed steel substrate to the required thickness. This layer provides the fire protection to the structural member.
  3. Finally, a decorative and protective top coat may be applied over the installed intumescent coating. This finish coat can be any color and gloss level and should be a material that will protect the intumescent coating against high humidity and other potentially harsh interior environmental conditions, while providing a smooth, attractive, architectural finish.

 

Exterior
Application is performed through a four step, process.
  1. The first step of the intumescent system is the application of a compatible steel primer to the steel substrate.
  2. Next, the intumescent base coat is applied to the primed steel substrate to the required thickness. This layer provides the actual fire protection to the member.
  3. Then, SprayFilm® WB 4 is coated with two coats of SprayFilm Topseal.
  4. Finally, a decorative and protective top coat shall be applied over the installed Topseal. The exterior finish coat can be any color and gloss level and must be specifically approved for use by Isolatek International. This exterior finish coat will protect the SprayFilm WB 4 system, while providing a smooth, attractive, architectural finish.

Maintenance

Intumescent Fireproofing, also known as Intumescent Fire Resistive Materials (IFRMs), is designed to provide hourly fire resistance ratings to the structural steel framework of a building. Routine inspection of IFRMs ensures that the product will be in-place for the design life of the structure and will perform in actual building fire conditions. IFRMs are typically specified and installed in areas where structural steel columns and beams will be exposed to view and where high amounts of foot traffic and contact are prevalent, due to their ability to resist damage, impact and abrasion. Severe impacts to IFRMs caused by the operation of heavy equipment, transportation of goods, etc. may damage the IFRM and if so, will require inspection and remediation in those areas.

 

The procedures outlined below are intended as a guide for the inspection of IFRMs while conducting your periodic maintenance program.
  1.  Identify all areas throughout the structure that are subjected to severe impact. In addition, identify all areas that are susceptible to periodic or regular maintenance traffic and periodic or regular public traffic.
  2. Visually inspect the aforementioned areas and note all IFRM deficiencies such as material that has been damaged.
  3. Inspect surrounding IFRM near the damaged areas to ensure the required thicknesses are maintained.
  4. Identify the type of IFRM utilized to protect the structural steel framework; i.e. beams and columns. The type of IFRM can usually be determined by reviewing construction documents or by contacting IFRM Manufacturers.
  5. Obtain instructions from the applicable IFRM Manufacturer detailing the repair procedures.
  6. Secure a sufficient quantity of IFRM from the applicable Manufacturer or contact the Manufacturer for names of qualified installers of the IFRM type. Repair of the existing IFRM shall be performed in accordance with the Manufacturer’s published installation instructions.
