Mumbai, September 24: The Ministry of Road Transport & Highways / MORTH has issued a Draft Notification to introduce Fire Alarm System and Fire Protection System in Passenger (or Occupant) Compartment in buses through a modification in AIS (Automotive Industry Standard)-135.
 
MORTH_1  H x W:
 
Currently, fire detection, alarm and suppression systems are notified for fires originating from only the engine compartment.
 
The draft notification is intended for fire detection and protection in the passenger compartment for Type III buses [‘Type III’ buses are those designed and constructed for long distance seated passenger transport] and School Buses.
Studies on fire incidents indicate that injuries to passengers are mostly because of heat and smoke in passenger compartment. These injuries can be prevented if heat and smoke in the passenger compartment is controlled by providing an additional evacuation time (of at least 3 minutes) to occupants by thermal management during fire incidents.
 
 
 
A technical solution to this problem has been developed by the Ministry in consultation with various stakeholders, including DRDO. A water mist-based active fire protection system has been designed, developed along with a fire alarm system.

Simulation studies showed that designed system is able to manage the temperature in the passenger compartment within 50˚ C centigrade in less than 30 seconds of the mist operation.
