This standard provides information
that is useful for the medical evaluation of
respirator users. This standard does not
deal with medical surveillance or biological
exposure monitoring. It is understood
that local circumstances vary, that no set
of guidelines can cover all situations, and
that specific programs and procedures
should be modified for each individual
workplace. Medical evaluation is only one
element of a complete respiratory protection
program. A complete respiratory protection
program is defined in ANSI
Z88.2?1992.
