Ford Fiesta Air Bags

Hi there,
Is it possible for the air bags to pop out without a
collision. Domething stramge happened to me on
wednesday 4th Dec on my way back from work as
ot was peak hour there was heavy traffic cars were
moving at about 20-30kms as it was slow moving
i was looking around then all i could remember
was my air bags poped along with the foot bag in
a shock which made me hit accelerator and hit the
car infront of me. Is this a posibility ??
