## Narrative

A Tire Shop repairman was preparing to air up the #1 tire on a haul truck and connected the ""big air"" hose connection onto the valve stem.  As they made the connection, they noticed the big air hose bleeding off, so they tightened it, and as they were doing it, air bled through with enough pressure to make the hose whip around and strike them on their chin.
