The Building Regulations require certain elements of structure to have fire resistance for a specified minimum period of time. The amount of fire protection to achieve this depends on the following:

1. Duration of fire resistance specified
2. Type of protection used
3. Perimeter of the steel section exposed to fire
4. Shape and size of the steel section

TYPES OF STEEL PROTECTION

Calcium silicate board / Magnesium silicate board will be used to clad the steel beams columns which need to be protected from Fire. Various types of calculations need to be done to determine specifications of the construction system.

Tests in accordance with BS 476 : Part 21 have been performed on loaded beams and columns clad with fire protection material. Steel surface temperatures are monitored with thermocouples to assess the performance of the cladding, since steel fully stressed in accordance with BS 449 or BS 5950, Part 1, begins to lose its design margin of safety at temperatures around 550°C.

Intumscent coating is thin film pain(is it pain or plain) composition that reacts to heat in a fire situation, rapidly expanding to form an insulating foamed char many times the original thickness. The char isolates the steel sections thus reduces the rate of temperature increase and prolongs the load bearing capacity of the section. This allows the designer to use the natural look of steel to enhance the appearance of the structure. The thin film applications increase the opportunities for both Architects and Engineers to be more flexible in design strategies and this can be applied internally and externally. A top coat may not necessarily be required for international application for fire protection purpose.

Spray for fire protection system which restricts the effects of cellulosic fire on building elements and whole structures. In addition, complementary systems are also available to improve the thermal and acoustic performance of structures.

United Fire Stopping can select the manufacturers system that are required to meet Fire safety.

Fire rated tested ceiling systems up to 240 minutes FRL are available for installations. Self supporting or suspended ceilings is generally non-load bearing and are provided horizontal barriers to prevent vertical spread of fire. Fire rated ceilings are to be approved with relevant criteria BS 476 Part 22.

Wall boards with water resistance, with good thermal resistance are used for Fire rated ceilings.

Based on FRL required, the ceiling system will be decided as per tested conditions. GI framing with proper selection of ceiling board (Promat boards/Magnesium silicate) and infill will give (96 Kgs Rock wool) adequate acoustic, water resistance also, apart from integrity and insulations.

Access panel (Fire rated) can also be provided where access to ceiling is required and essential.

Grid ceilings generally are not system tested for Fire ratings, though ceiling boards are often non combustible products.

Duct system should be capable of resisting the ravages of fire for a period of time, so as to perform its intended function.

Ducts can be classified as

• Duct – A - exposed to external fire
• Duct – B - exposed both – External & internal fire

Duct system must satisfy all the relevant performance criteria of stability, integrity and insulation.

Duct works fall in to following categories.

1. Ventilation and air conditioning
2. Natural smoke extract
3. Fan assisted smoke extract pressurization of escape routes and fire fighting lobbies

Fast and interrupted smoke extraction during fire, preventing spread of smoke is a key factor in protection of ducts. Fire rating of the duct shall be achieved using Fire Rated constructions / protection to the duct work.

Smoke kills more people than fire – hence protect ducts against fire

Openings are necessary in any part of the building area to accommodate for the services running across. Structural elements also require space to allow for natural expansion / contraction which acts as opening for spread of fire and smoke.

It is a matter of life safety to seal and stop spread of Fire and smoke by effective and tested Fire Stop Systems..

Fire stopping systems can be broadly classified as

1. Permanent
2. Semi permanent
3. Temporary
4. Closing of small gaps.

Permanent and long lasting fire stopping system is achieved through one of the following
