Skull caps under respirators

["Brian Rees" <brees@lanl.gov>]

I have been told that the ANSI (or similar) standard states that nothing 
shall be worn underneath a respirator.  Thanks to the interpretation of 
this, by people who will never wear a respirator occupationally, this has 
been interpreted at some facilities to include skull caps under 
respirators.  I KNOW that the important part of wearing a respirator is 
keeping a seal, and interference with the seal is the point, BUT, some 
people are much more interested in their own agendas than the real issues 
of health physics.
