Some air bag technologies use compressed nitrogen or argon gas with a pyrotechnic operated valve ("hybrid gas generator"), while other technologies use various energetic propellants. Propellants containing sodium azide (NaN3) were very common in early inflator designs. However, propellants containing sodium azide were widely phased out during the 1990s in pursuit of more efficient, less expensive and less toxic alternatives.The azide-containing pyrotechnic gas generators contain a substantial amount of the propellant. The driver-side airbag may contain a canister which is 5,0 cm (2") in diameter, 3,8 cm (1.5") long, and contains about 50 grams of sodium azide. The passenger side container is 15 cm (6") long and contains 200 grams of sodium azide. [8] The incomplete combustion of the charge due to rapid cooling leads to production of carbon monoxide (CO) and nitrogen(II) oxide as reaction byproducts. [9]The alternative propellants may incorporate eg. a combination of nitroguanidine, phase-stabilized ammonium nitrate (NH4NO3) or other nonmetallic oxidizer, and a nitrogen-rich fuel different than azide (eg. tetrazoles, triazoles, and their salts). The burn rate modifiers in the mixture may be an alkaline metal nitrate (NO3-) or nitrite (NO2-), dicyanamide or its salts, sodium borohydride (NaBH4), etc. The coolants and slag formers may be eg. clay, silica, alumina, glass, etc.[10] Other alternatives are eg. nitrocellulose based bipropellants (which have high gas yield but bad storage stability, and their oxygen balance requires secondary oxidation of the reaction products to avoid buildup of carbon monoxide), or high-oxygen nitrogen-free organic compounds with inorganic oxidizers (eg. di or tricarboxylic acids with chlorates (ClO3-) or perchlorates (HClO4) and eventually metallic oxides; the nitrogen-free formulation avoids formation of toxic nitrogen oxides).From the onset of the crash, the entire deployment and inflation process is faster than the blink of an eye (about 0,2 seconds). Airbags deploy in about 0,05 seconds. Because a vehicle changes speed so fast in a crash, air bags must inflate rapidly if they are to help reduce the risk of the occupant hitting the vehicle's interior.Once an air bag deploys, deflation begins immediately as the gas escapes through vent(s) in the fabric (or, as it's sometimes called, the cushion). Deployment is frequently accompanied by the release of dust-like particles and gases in the vehicle's interior (called effluent). Most of this dust consists of cornstarch or talcum powder, which are used to lubricate the air bag during deployment. Newer designs produce effluent primarily consisting of harmless talcum powder/cornstarch and nitrogen gas (about 80% of the air we breathe is nitrogen). In older designs using an azide-based propellant (usually NaN3), varying amounts of sodium hydroxide nearly always are initially present. In small amounts this chemical can cause minor irritation to the eyes and/or open wounds; however, with exposure to air, it quickly turns into sodium bicarbonate (baking soda). However, this transformation is not 100% complete and invariably leaves residual amounts of hydroxide ion from NaOH. Depending on the type of air bag system, potassium chloride (a table salt substitute) may also be present.Uglavnom je punjeno azotom i ostalim gasovima koji se sire ogromnom brzinom i na taj nacin se napumpa jastuk u vremenu od 0,2 do 0,5 sec... ne da mi se prevoditi
