DRDO builds fire fighting system for passenger buses

The active fire protection system has been developed as a defence spin-off tech.

New Delhi: Defence Minister Rajnath Singh and Minister for Road Transport and Highways Nitin Gadkari witnessed the demonstration of Fire Detection and Suppression System (FDSS) developed by DRDO for Passenger Buses at DRDO Bhawan here today 09 Nov 2020.

Demonstrations were given on Water Mist Based FDSS for Passenger Compartment and Aerosol Based FDSS for engine fire. They were also briefed about the various other programs and systems.

DRDO’s Centre for Fire Explosive and Environment Safety (CFEES), Delhi has developed the technology, which can detect the fire in passenger compartment in less than 30 sec and then suppresses it in 60 sec thereby reducing the risk to life and property to a significant extent.

The FDSS for passenger compartment comprises of a water tank of 80 litre capacity, a 6.8 kg nitrogen cylinder pressurized to 200 bar installed at appropriate location in the bus and a network of tubing with 16 number of atomizers inside the passenger compartment. The FDSS for engine comprises of aerosol generator with which the fire suppression could be achieved within 5 sec of the system activation.

CFEES has unique competency in the areas of fire risk assessment, fire suppression using different extinguishing mediums, modelling and simulation. They have developed system for Battle tanks, ships and submarines.

The active fire protection system has been developed by CFEES as a defence spin-off technology for providing a solution to the fire incidents in passenger buses. Although, the fire threat is present in all the vehicles, the highest concern emanates from special vehicles particularly the school buses and the sleeper coaches for long distance travel. As on date, only the engine fire is regulated for fire safety.
