The airbag system consists of components such as collision sensors, control systems, ignition elements, and nylon airbags. The entire airbag is usually folded and placed in the steering wheel cover and the dashboard opposite the front passenger seat. Some vehicles also have airbags built into the roof, doors and seats, etc.

An airbag will not block the driver's vision in a crash – it inflates and deflates faster than you can blink.

• Airbags are not soft. They inflate incredibly quickly – the front of an airbag moves towards you at between 160 to 320km/h.
• Airbags can't be added to a car like some other equipment. They are designed to work with the safety system of a specific car model.
• Some are bigger than others. Driver airbags in European cars are usually about 30–45 litres; American models may be up to 70 litres. Passenger airbags are typically much bigger.

A life-saving 0.03 seconds

How does the airbag system containing sodium azide work?

When an accident occurs, the collision sensors located at the left and right ends of the front of the vehicle will sense the stall state of the vehicle body and then send out electrical signals through the control system. After receiving the transmitted electrical signal, the ignition element initiates the electric heating program. The sodium azide in it will explode within just 0.03 seconds after being heated.

After the explosion, the nitrogen gas released will quickly expand, fill and eject the folded airbag, blocking the steering wheel, dashboard, driver and front passenger. Not only that, there are also tiny air holes on the airbag, which can gradually release the nitrogen in the airbag, allowing it to fully exert its buffering effect without affecting people's activities.

Studies show that when airbags are used correctly in a car accident, the fatality rate of the driver inside the vehicle can be reduced by 29%, and that of the passenger in the front passenger seat can be reduced by 32%. It can truly be said that "the explosion saved lives!"

Airbags can cause injury. To reduce this risk, newer airbags inflate more slowly. Some adjust to different types of crash or passenger size.

• Always wear a safety belt.

• Don't sit too close to the steering wheel or slide the seat a long way forward.

• Don't rest anything over the airbag cover or put anything between you and the airbag (except a safety belt).

• Never put a rear-facing child restraint in the front seat of a vehicle with a passenger airbag.

• If your car crashes and the airbag inflates, legally you must replace the airbag if the car is less than 14 years old.

• Read your vehicle manual for any other information about its airbags.
