What Type of Gas is in an Airbag?
1 Answers
Automobile airbags are filled with nitrogen gas, which inflates the airbag within 0.1 seconds. Relevant information is as follows: 1. The airbag contains solid sodium azide (NaN3), which rapidly decomposes upon severe impact to generate a large amount of nitrogen gas. 2. The airbag system is a passive safety protection system (see automotive safety performance). When used in conjunction with seat belts, it provides effective collision protection for occupants. In a car collision, airbags can reduce head injury rates by 25% and facial injury rates by approximately 80%. 3. The airbag system mainly consists of sensors, a microprocessor, a gas generator, and the airbag. Sensors and the microprocessor are used to determine the severity of a crash and transmit signals. The gas generator, upon receiving the signal, ignites the solid fuel to produce gas that inflates the airbag, causing it to expand rapidly.
