You are right but I think you misunderstood what Sam was explaining. A

Sam E is so right! There have been cases where workers (and kids) have

I mean kids filling push bike not motor bike tyres. It does not take
much air volume to fill the former to bursting point. We have had one
or two accidents over here so gas stations warn you against using their
air lines for such a purpose.

A true story:
A tyre fitter left a new truck tyre and centre on the floor hooked up to
an airline and left it. When he remembered it he rushed back and
unfortunately leaned over the tyre to try and pull the airline off. His
colleagues heard the explosion and rushed to see what had caused it.
