Automatic, rapid-response fire protection for diesel, petrol, CNG & EV bus engine compartments — compliant with national safety standards
Engine compartment fires are among the most frequent and most dangerous fire incidents in buses. Fuel leaks, overheated components, electrical short circuits, turbocharger failures and oil mist ignition can cause fires that spread within seconds—often while the vehicle is in motion.
LIFEGUARD® Bus Engine Fire Suppression System is a fully automatic, engineered fire protection solution designed to detect and suppress fires at the source inside the engine compartment, minimizing risk to passengers, drivers and assets. Developed in alignment with Indian national fire safety standards and transport safety requirements, the system is suitable for city buses, intercity coaches, school buses, electric buses, and public transport fleets.
Bus engine compartments present a high-risk fire environment due to:
Presence of flammable fuels (diesel, petrol, CNG)
Hot engine surfaces and turbochargers
Hydraulic oil and lubricants
Dense electrical wiring and battery systems
Restricted airflow and limited manual access
Once a fire starts, manual intervention is unsafe and often impossible, making automatic detection and suppression critical.
The LIFEGUARD system is designed as a standalone or integrated module, consisting of:
Automatic Fire Detection
Linear heat detection tube / heat sensors
Suppression Agent Storage Cylinder
Agent selected based on engine type
High-Integrity Piping & Nozzles
Engineered for uniform discharge
Control Valve & Actuation Mechanism
Manual Actuation Option for Driver
System Status Indicator (Cabin Alert)
The system activates within seconds of fire detection, suppressing the fire before it spreads beyond the engine bay.
Smothers flammable liquid fires
Cools hot engine surfaces
Prevents re-ignition of fuel vapors
Specifically engineered for lithium-ion battery fires
Cools and encapsulates battery modules
Provides re-ignition resistance
Agent selection is customized to the fuel type and engine architecture.
LIFEGUARD Bus Engine Fire Suppression Systems are designed in compliance with:
AIS (Automotive Industry Standards) for bus fire safety
CMVR (Central Motor Vehicle Rules)
NBC principles for fixed fire suppression systems
PESO-referenced safe practices (for pressure vessels)
Guidelines issued by State Transport Authorities (STUs)
Documentation supports type approval, fleet tenders and statutory inspections.
