What is the stuff that comes out of airbags?

Sodium azide is best known as the chemical found in automobile airbags. An electrical charge triggered by automobile impact causes sodium azide to explode and convert to nitrogen gas inside the airbag.

Do airbags leave residue?

During deflation, the nitrogen gas vents through very small holes in the bag. The deflation can produce a fine powdery cloud of residue that will settle on clothing, vehicle surfaces, hair, and exposed skin. The residue is dissipated very quickly from the airbag. Once the bag has deflated, no more residue is released.

Are air bags toxic?

Sodium azide is an extremely toxic poison, capable of destroying entire ecosystems. An undeployed airbag contains between 50 grams for the driver side and 200 grams for the passenger side. After the airbag reacts, all of the sodium azide should be converted to harmless nitrogen gas.

Is a deployed airbag hazardous?

When an airbag is deployed, sodium azide is converted into harmless nitrogen gas by other chemicals in the inflator. In fact, a fully deployed airbag can simply be handled as solid waste and disposed of in the garbage. But sodium azide in isolation is toxic, dangerous to inhale, and can burn exposed skin.

Why do airbags smell bad?

When an airbag deploys, it is a startling and sometimes frightening situation. The airbag deploys so suddenly that it can almost feel like your initial collision. It makes a loud pop and emits a very distinct smell of burnt rubber or fabric. It is common to sustain minor burns from airbags as well.

Why do airbags have holes?

The bag itself has tiny holes that begin releasing the gas as soon as it’s filled. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck.

How does it feel to be hit by an airbag?

When an airbag goes off, it can be painful. It can feel like being kicked in the face and chest by a very strong but fluffy bunny. Airbags are meant to keep you from hitting the hardest parts of your car, like the steering wheel, dashboard, glass windows, or metal doors.

When an airbag deploys there is often a chalky residue on the person who is in front of that airbag What is the purpose of this powder is it harmful?

Either nitrogen or argon gas is used to inflate an airbag. Both of these gases are non-toxic. Immediately after a deployment, “smoke-like” residue will be present in the air. Most of this residue is talcum powder that is used as a lubricant to help the airbag deploy smoothly.

What happens when a airbag hits you?

Common types of injuries caused by airbags are: Abrasions to the upper portion of the body, including arms, chest and face. Contusions to arms, knees, chest, face and internal organs. Concussions, brain swelling, brain bruising and loss of consciousness.

How bad does airbag hurt?

When an airbag goes off, it can be painful. It can feel like being kicked in the face and chest by a very strong but fluffy bunny. But the force of hitting the airbag can cause (less serious) injuries from abrasions to broken bones. If your airbags deploy, your car may be totalled.

How do you dispose of a non deployed airbag?

Although recycling of airbags is legal, it isn’t free. Generally you will have to locate a recycler in your area or one that will take shipments. There is typically a per-unit fee that has to be paid. In some cases, you may be able to drop your airbag off with a dealership or a salvage yard locally.

Are undeployed airbags hazardous waste?

Undeployed airbag inflators and airbag modules are generally reactive (D003) and/or ignitable (D001) due to the propellant contained in the inflator, and therefore hazardous wastes under the RCRA when discarded.

What are the effects of air bag dust?

In rarer cases, air bag dust can be extremely severe or even fatal. The effects of the air bag dust can vary from person to person 1. Air bag dust often causes irritation to mucus membranes and air passages, which has serious effects on breathing. If sodium azide is breathed in, there can be serious effects.

What to do in the event of an air bag deployment?

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.

What are the chemical reactions in an airbag?

Chemical Reactions Used to Generate the Gas Inside the airbag is a gas generator containing a mixture of NaN3, KNO3, and SiO2. When the car undergoes a head-on collision, a series of three chemical

Why do airbags help reduce the force of injury?

Because the gas can only leave at a certain rate (recall the kinetic theory of gases), the bag deflates slowly, and therefore Δt increases. Additionally, airbags help reduce injuries by spreading the force over a larger area.
