pressure.air-purifying.respirator.face.piece.with.the.same.sealing.surfaces.as.a.sur-
rogate.for.the.atmosphere-supplying.or.powered.air-purifying.respirator.face.piece.
Quantitative.it.testing.of.these.respirators.must.be.accomplished.by.modifying.
the.face.piece.to.allow.sampling.inside.the.face.piece.in.the.breathing.zone.of.the.
user,.midway.between.the.nose.and.mouth..This.requirement.shall.be.accomplished.
by.installing.a.permanent.sampling.probe.onto.a.surrogate.face.piece,.or.by.using.
a.sampling.adapter.designed.to.temporarily.provide.a.means.of.sampling.air.from.
inside.the.face.piece.
Any.modiications.to.the.respirator.face.piece.for.it.testing.must.be.completely.
removed,.and.the.face.piece.restored.to.NIOSH.approved.coniguration,.before.that.
face.piece.can.be.used.in.the.workplace..Fit.test.records.shall.be.retained.for.res-
pirator.users.until.the.next.it.test.is.administered..Written.materials.required.to.be.
retained.must.be.made.available.upon.request.to.affected.employees.

Respirators.will.only.be.used.following.the.respiratory.protection.safety.procedures.
established.in.this.program..The.operation.and.use.manual.for.each.type.of.respirator.
must.be.maintained.by.the.respiratory.program.administrator.and.be.available.to.all.
qualiied.users.
Surveillance,. by. the. direct. supervisor,. shall. be. maintained. of. work. area. condi-
tions.and.degree.of.employee.exposure.or.stress..When.there.is.a.change.in.work.area.
conditions.or.degree.of.employee.exposure.or.stress.that.may.affect.respirator.effec-
tiveness,.the.company.must.re-evaluate.the.continued.effectiveness.of.the.respirator.
For.continued.protection.of.respirator.users,.the.following.general.use.rules.apply:
.
1.. Users.shall.not.remove.respirators.while.in.a.hazardous.environment.
.
2.. Respirators.are.to.be.stored.in.sealed.containers.out.of.harmful.atmospheres.
.
3.. Store.respirators.away.from.heat.and.moisture.
.
4.. Store. respirators. such. that. the. sealing. area. does. not. become. distorted. or.
warped.
.
5.. Store.respirators.such.that.the.face.piece.is.protected.
To. ensure. face. piece. seal. protection,. the. company. should. not. permit. respira-
tors.with.tight-itting.face.pieces.to.be.worn.by.employees.who.have.facial.hair.that.
comes.between.the.sealing.surface.of.the.face.piece.and.the.face.or.that.interferes.
with. valve. function.. The. same. applies. to. employees. who. have. any. condition. that.
interferes.with.the.face-to-face.piece.seal.or.valve.function.
If.an.employee.wears.corrective.glasses.or.goggles.or.other.personal.protective.
equipment,.the.company.shall.ensure.that.such.equipment.is.worn.in.a.manner.that.
does.not.interfere.with.the.seal.of.the.face.piece.to.the.face.of.the.user.

their.faces.and.respirator.face.pieces.as.necessary.to.prevent.eye.or.skin.irritation.
