Passive Fire Protection Services

Concept of Fire-Resistant Cable Coating

Cables are prone to self-igniting locally due overheating caused by short circuiting. They can also be overheated due to external factors such as fires. Fire-resistant cable coatings are used to prevent the propagation of fire along internal electrical cables and to protect the functionality of those cables .These coatings are used worldwide in a wide variety of structures, including service tunnels, power plants, substations, and electrical and plant rooms.

OMNIV offers application of spray and brush-applied fire-resistant coatings on cables and cable-trays, preventing the spread of fire for 30 minutes and the ignition of cables for at least 40 minutes, even with a direct flame and surrounding temperature higher than 260°C. The applied coatings retard any direct flames travelling through horizontal and vertical cables and cable trays. OMNIV offers its expertise in application of cable coatings in accordance with the project specifications, industry standards, and manufacturers’ recommendations.

OMNIV offers application of four basic types of fire resistant ductwork that could be required or have special use under fire conditions. The following terms are used in identifying varying performance criteria for such ducts.

  • Ventilation fire ductwork
  • Smoke Extract ductwork
  • Non-domestic kitchen extract ductwork
  • Pressurization ductwork

OMNIV provides two kind of tunnel fire protection systems

Fire Board Panel Systems

Fire board panel systems have been developed to create a protective membrane either directly fixed to the structure or to a steel framing system. This framing system can be suspended from the load-bearing structure or, depending on the span of the ceiling, can be suspended along the walls of the tunnel only. From below the Fire board panels will be screwed or bolted to the suspended steel frame to enable the removal for inspection at a later date. In case of refurbishment of the tunnel, the protective membrane system is both technically and commercially the most feasible option.

Fire Spray Systems

Fire spray systems have been developed as a proven method of fire protection for the tunnels industry. They include a range of integrated coating systems that restrict the effects of hydrocarbon fires on tunnel structures, and improve the sound absorption performance on the tunnel linings.

Fire spray systems are an applied, single package factory controlled premix, based on vermiculite and Portland cement, producing a monolithic coating able to withstand the thermal shocks experienced in a high intensity hydrocarbon fire. Concrete structures in particular, will be protected from explosive spalling when coated with fire spray products. Minimum practical thicknesses of 8mm unreinforced and 15mm reinforced, can be achieved offering the designer advantages should the traffic clearance envelope be critical within the road tunnel.

Dependent upon the road tunnels design requirements, fire spray systems can be trowelled smooth and coated to withstand the severe sulfur laden atmospheres encountered in road tunnels, whilst enabling ease of cleaning, increased light reflectance, and protection of the concrete from exhaust deposits, de-icing salts etc.

Fire Barriers

Fire barriers systems are slabs of high density rock wool with a white endothermic, ablative coating designed to stop the spread of fire through openings in fire resistant walls or floors. Fire barriers provide an enhanced acoustic performance and up to 240 minutes fire protection.

Fire Compounds

Fire compound systems are gypsum based with thermal and acoustic properties, which provide a fire seal around service penetrations in walls and floors. Fire compound systems are particularly designed for use where a loading of the penetration is applicable, such as service risers and plant room floors. Fire compounds are quick setting to provide a smoke seal offering up to 240 minutes fire resistance.

Intumescent Sealants

Intumescent Sealant systems are water based acrylic intumescent or silicone based fire protection sealants. Adhering to most types of surface, which when cured form a non-hardening seal; preventing the passage of smoke, toxic gases and fire for up to 240 minutes fire protection.

OMNIV Technical team can provide the following services

  • Bill of Quantities preparation and study.
  • System design to manage the process of documenting all fire barrier penetrations and firestops within a building.
  • System maps the location of all walls and floors, inventories each firestop (along with a picture of the installation) and records when it was installed, what materials were used and its ULC System number.
  • Labeling system on fire-rated walls and floors provide a permanent record of firestop locations for contractors doing renovation work.Our staff’s knowledge of firestop systems is impeccable and the workmanship, scheduling and quality control system are every time beyond our client expectations.

OMNIV specializes in application of intumescent fireproofing coatings for hydrocarbon-fires and jet-fires in the Oil & Gas environment. OMNIV PFP applies both solvent-based and water-based intumescent fireproofing coatings.

There are two common types of fire that may occur in a hydrocarbon-processing complex: The first is a pool fire and this occurs when a flammable liquid leaks from a vessel or pipeline to form a fluid reservoir, which then ignites; The second, and potentially more dangerous type, is a jet fire which can happen following the rupture of a pressurized vessel and/or gas line.

A hydrocarbon pool fire will generate temperatures of more than 1000 Celsius within ten minutes of ignition with heat fluxes of around 150kW/m2, while a jet fire will exhibit the same temperature rise, but the heat flux could be double that of the pool fire. Three distinct types of passive fire protection products are normally used in hydrocarbon-processing complexes:

  • Cementitious products generally based on Portland cement plus lightweight aggregates. Cementitious materials protect the steel in two ways. Firstly, they contain trapped moisture, which in a fire situation will boil and keep the steel temperature around 100 Celsius until all the water has disappeared. The product then acts, secondly, as an insulator.
  • Intumescent coatings generally epoxy based spray or hand applied. In the event of a fire these coatings intumesce (i.e. they swell to many times their original thickness) to form a tough insulating char.
  • Blanket systems made from man-made fibers which use insulation as their primary fire protection mechanism. They are used primarily for cable tray and valve protection

OMNIV can accommodate every aspect of fireproofing needs.

We hold licenses for most of the fireproofing products and our highly experienced professional installers and management team are trained and certified for the application of the industry’s most requested products.

We are skilled in the application of :

Thin-film Intumescent Fire Protective Coatings

Thin film applied Intumescent paint is a fast method of providing up to 180 minutes fire protection to structural steelwork. Intumescent coatings provide an appearance similar to that of paint, with basic to high gloss finishes now available. At ambient temperatures Intumescent paint systems remains stable. However in a fire condition, the increase in temperature activates a chemical reaction which then causes the intumescent coating to expand many times its original thickness.

Cementitious Fire Spray

Cementitious fire spray is a fast and efficient method of providing up to 240 minutes fire protection to structural steelwork. Used in the commercial, petro-chemical and tunnels markets, cementitious fire sprays withstand impact and abrasion, yet remain flexible to accept design changes without incurring major cost and time delays.

Cementitious fire sprays may be applied within environments where limited exposure to the elements is likely throughout the building phase of the project. They can also be used for application to steel and concrete frames, metal floors or roof decks and return air plenums.

Boarded Fire Protection Systems

Boarded fire protection systems offer a non-combustible and cost efficient method of providing up to 240 minutes fire protection to structural steelwork. As the original means of affording structural fire protection, this method has seen major developments in the types of boards available today.

Boarded fire protection systems can be durable, resistant to water and beneficial to acoustic performance. Certain fire boarded systems are able to accept decorative applications, such as paint or plaster, providing an aesthetic finish without the need for further preparation.
