Advanced, people-safe fire protection for passenger areas of buses, coaches & public transport systems — compliant with national fire safety standards
Fire safety inside passenger buses is no longer optional—it is a critical life-safety requirement. With increasing passenger density, extensive electrical wiring, HVAC systems, interior furnishings and the growing integration of EV components, the risk of fire in bus passenger compartments has significantly increased.
LIFEGUARD® Bus Passenger Fire Suppression System using Watermist is an engineered, automatic fire protection solution designed specifically to detect, control and suppress fires in the passenger area of buses while ensuring maximum safety for occupants. The system is developed in line with applicable Indian national fire safety standards, best practices, and transport safety guidelines, making it suitable for public transport fleets, school buses, intercity coaches, electric buses, rail coaches, and other mass transit vehicles.
Unlike engine fires, passenger compartment fires pose direct and immediate risk to human life due to:
Limited evacuation time
Enclosed space with smoke accumulation
Presence of children, elderly and differently-abled passengers
Upholstery, plastic panels and luggage contributing to fire load
Manual firefighting inside a moving or crowded bus is often impossible. Hence, automatic detection and suppression becomes essential.
Watermist technology uses ultra-fine water droplets to control and extinguish fires through multiple mechanisms, making it ideal for occupied spaces.
Fine mist absorbs heat efficiently, reducing fire temperature rapidly and preventing flashover.
Mist droplets convert to steam at the flame zone, locally displacing oxygen without creating suffocation risk.
Uses up to 90% less water than conventional sprinklers, preventing water damage and slip hazards.
No chemicals, no residues, no inhalation hazards—ideal for passenger compartments.
Effective on Class A fires and safe around live electrical systems commonly present in buses.
The LIFEGUARD system is a fully integrated, automatic solution, consisting of:
Early Fire Detection Sensors (smoke / heat / linear detection)
Electronic Control & Alarm Unit
High-Pressure Watermist Cylinders / Pump Module
Stainless Steel Watermist Piping Network
Precision Atomizer Nozzles strategically placed across the passenger area
Manual Override & Emergency Activation Switch
Visual & Audible Alarms for Passengers and Driver
The system is designed to activate within seconds of fire detection, suppressing the fire at its incipient stage.
Watermist nozzles are designed and positioned to ensure:
Uniform mist distribution across seating rows
Coverage of luggage racks, ceiling panels and HVAC zones
Protection under seats where wiring and battery modules may be present
Typical configurations include 8–14 atomizer nozzles, depending on bus length and seating layout.
LIFEGUARD Bus Passenger Watermist Systems are designed in line with:
AIS (Automotive Industry Standards) applicable to bus fire safety
CMVR (Central Motor Vehicle Rules) fire safety requirements
NBC (National Building Code) – principles of watermist fire suppression
BIS & PESO referenced safety practices (where applicable)
Fire safety recommendations by State Transport Authorities & Urban Transport Bodies
System design, components and installation documentation support type approval, fleet audits and statutory inspections.
Government and private bus fleets
Sleeper and semi-sleeper coaches
Electric and hybrid buses
Enhanced safety for children
Automatic response without driver intervention
Passenger area protection independent of battery chemistry
Safe coexistence with engine/battery fire suppression systems
Passenger saloons
Driver cabins and vestibule areas
Airport shuttle buses
Staff transport buses
Tourist coaches
LIFEGUARD follows a zonal fire safety philosophy:
| Bus Zone | Recommended Technology |
|---|---|
| Passenger Area | Watermist Fire Suppression |
| Engine Compartment (Diesel/Petrol) | Mechanical Foam |
| EV Battery Compartment | HMS (Hydrated Mica Suspension) |
| Driver Cabin | Watermist / Clean Agent |
This ensures maximum effectiveness with minimal collateral impact.
