1. A crash bag propellant composition comprising, in combination,(a) a metal azide salt component of a group 1(a)- or 2(a)-type metal;

  • and(b) an oxide of a non-toxic transition metal element sufficient to react with up to about 70% of said metal azide salt component; and

    (c) an effective amount of a modifier component represented by the formula
    
    
    space="preserve" listing-type="equation">Me.sub.x (An).sub.o whereinMe is defined as a cation of iron or copper;

    An is defined as phosphorus containing anion group which is chemically compatible with Me and capable of reacting with said metal azide salt component to obtain non-toxic by-products less basic than a metal hydroxide corresponding to said metal azide salt component; and

    x is defined as a positive number of about 1-4; and

    o is defined as a positive number not exceeding about 3, the sum of which does not exceed about 7.
