Compressed air commonly used to blow foreign material out of crevices must be
operated at a pressure of less than 30 p.s.i. and be designed so that if you
place your hand over the end of the nozzle (dead heading) the air will vent out
somewhere else, which will reduce/eliminate the chance for an air embolism in
the skin. Typically the nozzles have a hole at the tip and 2 or 3 holes around
the circumference of the nozzle near the tip.

I hope this helps some,

Rob

Rob -

I followed your very thorough reply except for the part about being
sure not to have a "dead-headed" air line. Can you explain what
"dead headed" means.

Thanks
