Fire Survival Cables – The Ultimate Guardian

According to India Risk Survey Report 2017, fire is one of the top 3 risks across Education, Hospitality, Infrastructure, Media, Healthcare Facilities and Retail industries.

The major cause of fire outbreak in infrastructure could be due to Cable Short Circuit, Faulty Equipment and Appliances, Flammable materials, Negligence, Inadequate training of staff, Poor wiring and maintenance, faulty circuits in electrical panels, and circuit breakers. As per the report, electricity is the most common cause of fire in buildings and infrastructure.

In India, National Building Code (NBC) provides guidelines for regulating the building construction activities across the country. It revolves around four major pillars of safety, i.e. structural safety, health safety, fire safety & public safety. Part 8 on Building Services of the Code elaborates on the essential requirements for electrical and allied installations in buildings to ensure efficient use of electricity including safety from fire and shock.

Fire protection and safety requirements are clearly laid out in NBC on Fire and Life Safety.

However, one of the most important components of any infrastructure is the wiring. There have been many developments in the wire and cable technology, in terms of cable design and advance technology Today, we have house wires that are Flame retardant with low smoke properties. These have risen primarily due to requirements of low smoke & toxicity in case of fire, as against the popular notion that fire kills more people, but it is smoke that kills.

Polycab fire survival cable (low smoke halogen free – LSHF) are suitable for use in various indoor & outdoor applications where continuity of power supply during the event of fire, is highly essential and corrosive gas evaluation could be a cause of hazard to the people or the precision instruments in high rise building , schools, hospitals, hotels, Malls, Subways etc..

Polycab Fire Survival cable is a result of continuous research & development and innovation in highly sophisticated and modern R& D centre which conforms to various IEC and BS specification. The cables are tested in leading labs and approved by many Indian public sector company and other industries.

In today’s building & installation, electrical cables & wires have a significant role in fire safety. Generally electrical insulation and sheathing compound catch fire unless it is fire retardant or fire resistant. This results in overheating of wires & cables arching, short circuit or electrical fault. Cables contribute significantly to the spread of fire and heat emission, increased smoke emission, increased carbon monoxide level, production & release of corrosive gasses.

In order to meet the latest demands of environmentally friendly cables with increased safety in the event of a fire, Polycab offers a high range of product that meets:

  • The green & healthy environment
  • Halogen free environment which contributes to less corrosive gases and prevents the damage of human beings and equipment near the fire.
  • No emission of toxic gases which allows fire fighters to work and people to exit.
  • No release of dense smoke that improves the visibility of the exit routes and facilitates the rescue operation.
  • Takes much more time than the traditional cables to catch fire which helps in the evacuation of operation.
  • Excellent flame retardant properties that prevent the spreading of fire.
  • Maintains the circuit integrity of those vital instruments which help in the rescue operation, fire fighting and exit as follows:
  • Booster pump system
  • Rescue elevators
  • Water sprinkling system
  • Alarm hooters
  • Emergency lighting
  • Ventilation system
  • Fire & smoke detector system

Performance of cables in the event of Fire

In the event of fire, the cable develops hazards in respect of flame propagation, evaluation of smoke, heat development and toxic gasses etc. To evaluate the potential performance of the cable, many tests have been developed over the years.

The performance of the cable under fire condition is specified in several international standard as follows:

  • Flame Propagation Test: IEC 60332-1, BS EN 60332-1
  • Flame spread test: IEC 60332-1, BS EN 60332-3
  • Fire Resistance test: IEC60331, BS 6387
  • Resistant to Fire with water: BS 6387
  • Acid Gas emission test: IEC 60754, BS EN 50267
  • Determination of Acidity: IEC 50754, BS EN 50267
  • Smoke emission test: IEC 61034, BS EN 61034
  • Limiting Oxygen Index(LOI): BS EN ISO 4589, ASTM D 2863
