- Irrespective of the the type and intensity of collision, the decentralised safety systems in BMW cars are designed to react in an accident in a split second, coordinating the deployment of all necessary safety features, from airbags to seat belt pre-tensioners to active headrests.
The front-impact airbags protect the head during a frontal crash while the side impact airbags for the front seats protect the torso during a side impact collision. The overhead airbags protect the passengers' heads in case of a side collision or rollover and the knee airbags help to protect the lower extremities from serious injury.
The seat belt pretensioners automatically tighten seat belts to place the occupant in the optimal seating position during a collision.
The anti-whiplash head restraints react to rear collision forces and craddle the passengers' head in an effort to reduce the likelihood of an injury.
- The sensors in the A and B columns and in the doors of the vehicle register an accident at the earliest. The correct airbags are deployed to the appropriate degree, inflated to the optimum level depending on which seats are occupied and the severity of the impact. Seatbelt pre-tensioners and the optional active headrests are activated at the right moment.
- If necessary, the battery and generator are disengaged and fuel pump deactivated to reduce the danger of fire. The central locking system unlocks all the doors and the cabin light and warning lights are illuminated.
- In an accident, sensors measure the severity of the forces involved. The Advanced Safety Electronics (ASE) system uses a fail-safe optic fibre network to co-ordinate the safety system's response. ASE recognises which safety measures are needed and which are superfluous.
A mechanical failure, such as a stuck strap or brake pad causes massive overheating through friction can burn the car up in flames.
Electrical malfunction or short circuit can also cause fire in a car.
Loose connections in the fan pumps, radiator, accessories, plug and ignition wires can cause car fires since they do not have a proper grip system.
A fuel leak can cause the liquids to come into contact with areas of the vehicle which are hot enough to ignite them. This could have perhaps lead to the fire mishap in Sundar's case.
- In case the car is not well maintained and serviced, the ASE might not function properly in case of an accident hence causing fire. The diesel pipes, hose pipes and rubber tubes crack due to delayed servicing in many vehicles.
Seat belt: First, get your seat belt off before the heat of the fire fuses the metal of the buckle. Use a piece of cloth to release the buckle in case it is very hot. In case that does not work, push the shoulder strap.
Tools as saviours: It is important to unlock the doors and windows at the earliest. It is, therefore, adviced to keep tools like fire extinguisher and hammer in a car.
- The last resort: In case it becomes difficult to break the window and unlock the door to exit the car, a wool or flame-retardant or flame-resitant blanket can be used to protect you from burns and scalding.
