Why Is Fire Protection Required?

Arc Fire ProArc Firepro Ltd specialize in passive fire protection, all employees have attended training courses and gained certification for the application and knowledge of penetration sealing to Firas standards

Steel Work

The fundamental purpose of fire protection systems whether active or passive is to firstly, prevent the passage and spread of smoke and fire, from one area of the building to another, to allow for the safe escape of the building occupants. Secondly to prevent / reduce the amount of damage to the building structure, neighbouring structures and reduces the risk of collapse for the emergency services.
A number of the fundamental requirements of fire protection are specified in approved document B of the Building Regulations.
Means of escape, Internal surface spread of flame to linings, Structural integrity of the building. Fire compartmentation, Access and facilities for emergency services


Other more commercial reasons for the use of fire protection systems, is to reduce the amount of damage and prevent collapse of the building. This in turn can help to:
•    Reduce the possible risk to the fire fighters.
•    Reduce the rising cost of insurance policies.
•    Protect capital investment.

Passive Fire Protection

Passive systems in the form of fire rated doors, barrier, ceilings and structural fire protection.
The overall aim of passive systems is to contain the fire by:
Use of fire rated partitions and doors to prevent the fire and smoke from moving from one compartment to another.
Delaying the collapse of the structure.
Delaying the growth of the fire.

Intumescent coatings for the protection of structural steelwork

During a fire situation the temperature within a building can rise from ambient around 20oC, up to 1000 oC. As the temperature in the building increases, so does the temperature of the steel structure that supports the building. All steel sections have what’s known as a critical steel temperature. This is the temperature at which the steel section begins to lose its strength and buckle.
The building regulations require that structural steel is protected against fire, to ensure that the load-bearing strength of the steel is not decreased as the temperature increases.
There are 3 main systems to protect structural steelwork against the risk of fire:
•    Boarding: In the form of plasterboard / mineral fibre / Calcium silicate etc.
•    Spray: In the form of cementitious, mineral fibre or gypsum systems.
•    Intumescent: Thin film intumescent basecoats.

Determination of fire protection measures

The type of protection to use normally comes down to the following factors:
Fire performance required, 30/60/90/120 or 240 minutes.
•    Type of steel member to be protected.
•    The design and aesthetic requirements.
•    Weight restrictions.
•    Construction time.
•    Cost considerations.
•    Steel location, Internal or External
Cementitious spray systems are generally the cheapest method of protecting steelwork at 90 up to 240 minutes fire performance.
