LifeGuard 4Front™ frontal collision protection, the first advanced protection system of its kind for fire apparatus, helps protect firefighters in the most common type of collision – one that hits the apparatus head-on. 

How it works: 

1. A sensor inside the cab monitors the truck’s longitudinal accelerations
2. If the sensor detects a frontal crash of significant magnitude, it sends a signal to inflate an airbag on the steering wheel. Some systems also include a knee bolster airbag on the front passenger side that is inflated simultaneously.    
3. These three subsystems work together to dramatically reduce the risk of fatality or severe injury in a frontal collision.
