Government has issued notification for Fire Alarm system and Fire protection system in passenger compartment in buses. Road Transport and Highways Ministry said, at present, fire detection, alarm and suppression systems are notified for fires originating from the engine compartment. It said, studies on fire incidents indicate that injuries to passengers are mainly due to heat and smoke in the passenger compartment.<br />''<br />'' These injuries can be prevented if the heat and smoke in the passenger compartment is controlled by providing an additional evacuation time to occupants by thermal management during fire incidents. A water mist- based active fire protection system and a standalone fire alarm system for buses has been designed to manage the temperature in the passenger compartment within 50 degrees centigrade. The Ministry said, this amendment has been undertaken in consultation with stakeholders and experts from the Centre for Fire Explosive and Environment Safety.<br />
