Air bag dust & effects on breathing
Air bags are used as a safety device in all automobiles. (airbag image by Dimitar Atanasov from

Air bags in automobiles are designed to protect the vehicles' passengers, primarily in front-end or near-front-end collisions. They are designed to deploy when an impact's severity reaches the equivalent of a car hitting a brick wall at about 10 miles per hour.

Dust Particles Released

The dust particles released when an air bag deploys come from the various chemicals used to make the air bag open and fill with air quickly in the event of an emergency. The main dry-powder chemical, sodium azide (NaN3), ensures that the air bag device works effectively as soon as it is triggered by impact.

Effects of Air Bag Dust

The effects of the air bag dust can vary from person to person. Some people may not have a problem with the chemicals released while others will. Air bag dust often causes irritation to mucus membranes and air passages, which has serious effects on breathing. The most common symptoms from air bag dust are throat irritation and itchy, watery eyes. Both of which should be flushed with water and will heal after contact has been broken with the dust. In rarer cases, air bag dust can be extremely severe or even fatal.

Effects on Breathing

If sodium azide is breathed in, there can be serious effects. The deeper it's breathed in, the more severe the side effects will be. When possible, it is important to try to cover your mouth and nose in the event of an air bag deployment so as not to breathe in the dust. By getting out of the vehicle as soon as possible after air bag deployment, you can try to avoid serious effects from the air bag dust.

If airbag dust gets into the lungs, it can cause serious irritation that will lead to slower and shallower breathing. It may become difficult to catch your breath or take in a deep breath. Ingesting or absorbing even a small amount of the chemical can cause an average adult to fall into a coma-like state. If larger amounts are ingested, it can shut the body down completely.
