Composition and process for inflating a safety crash bag

A method for inflating an automobile or aircraft safety crash bag comprising the combustion of a pyrotechnic material, comprising at least one tetrazole or triazole compound containing hydrogen in the molecule, to generate substantially non-toxic combustion products including a gas to inflate said crash bag, said method comprising:

• (a) burning said pyrotechnic material at elevated pressure in admixture with at least one oxygen containing oxidizer compound and at least one metal oxide so as to produce, upon combustion, a substantially non-toxic primary gas mixture and easily filterable solids;
• and
• (b) diluting said primary gas mixture with air to produce a substantially non-toxic final gas mixture by passing said primary gas mixture through at least one venturi so as to aspirate said air, whereby said crash bag, when inflated, contains a final gas mixture comprising about 1 to about 4 volumes of air per volume of said primary gas mixture.
