Respirator Inspection Before each use:
Make sure you have
the right respirator
for the job
Inspect it for wearand damage.
7/29/2019 Respirator requirements
5/34
Inspection Points Check for worn or
frayed Straps &
Hoses.Look for wear or
damage on the seal
of the facepiece.
7/29/2019 Respirator requirements
6/34
Also CheckBe sure all the screws
are tight.
Check rubber and
plastic parts forflexibility.
7/29/2019 Respirator requirements

And Check Valves should be clean and seated
perfectly.
Check for cracks or deformities in theface shield.
Check condition of filters, cartridges orcanisters.
Damage to speaking diaphragm, if there isone.

Correct Filters & Canisters Ensure you have the correct Filters &
Cartridges for the job
NOTE: Color codes on cartridges & filters areonly a guide. Read the label to be sure youhave the right kind. If a combination of
elements is required check to ensure you havethe right combination on each side of therespirator.

Full Face Respirators Check the face
shield for clear
view
No cracks, gaps
or distortions.

Respirator Fit Check Conduct prior to each use.
For a respirator to work properly it must sealtightly to the face.
Before entering an area or conducting work thatrequires a respirator, conduct a fit check to ensure
it will keep out the air contaminants.
7/29/2019 Respirator requirements
13/34
Positive Pressure Check Close off the exhalation valve and exhale
gently into the facepiece.
The face fit is considered satisfactory if a
slight positive pressure can be built upinside the facepiece without any evidenceof outward leakage of air at the seal.
For most respirators, this method of leaktesting requires the wearer to first removethe exhalation valve cover before closingoff the exhalation valve, and then carefully
replacing it after the test.
7/29/2019 Respirator requirements
14/34
Negative Pressure Check Close off the inlet opening of the
canister or cartridge(s) by covering it
with the palm of the hand(s) or byreplacing the filter seal(s).
Inhale gently so that the facepiececollapses slightly, and hold your breathfor ten seconds.
7/29/2019 Respirator requirements
15/34
Safety Note: The design of some cartridges may require the
test be performed by covering the inlet opening
of the cartridge with a thin latex or nitrile gloveto effectively seal the inlet.
If the facepiece remains in its slightly collapsed
condition, and no inward leakage of air is
detected, the tightness of the respirator is
considered satisfactory.

Manufacturer's Procedures The respirator manufacturer's
recommended procedures for performing
a user seal check may be used instead ofthe positive and/or negative pressurecheck procedures, provided that they areequally effective in detecting seal leakage
compared to the positive pressure andnegative pressure checks previouslydescribed.

Respirator Cleaning Remove and clean filters, cartridges, valve
assemblies and any other detachable parts.
As you clean and dry each part of the
respirator, inspect carefully to be sure it is
in good condition.
7/29/2019 Respirator requirements
19/34
Basic Procedure Make sure flexible parts
are still flexible, and
check the stretch ofelastic bands.
Generally, a mild
detergent and a soft
brush are used for
cleaning.
7/29/2019 Respirator requirements
20/34
Rinse the respirator Thoroughly in clean, warm water. Rinsingis extremely important because a residue of
the cleaning agent can damage the
respirator and irritate skin.
Be sure all parts are thoroughly dry before
putting the respirator back together again.
Use a soft, lint-free cloth to absorb most of
the water and a fan to speed up the drying
process.

21/34
Disassemble Respirator Remove filters, cartridges, or canisters.
Disassemble facepieces by removingspeaking diaphragms, demand orpressure-demand valve assemblies, hoses,or any components recommended by the
manufacturer.
Discard or repair/replace any defectiveparts.
7/29/2019 Respirator requirements
22/34
Wash All Parts Wash components in warm
(43C/110F maximum) water with a
mild detergent or with a cleanerrecommended by the manufacturer.
A soft bristle (not wire) brush may beused to facilitate the removal of dirt.
7/29/2019 Respirator requirements
23/34
Rinse All Parts After Washing Rinse components thoroughly in clean,
warm (43C/110F maximum),
preferably running, water.
Drain the parts to remove excess water.
7/29/2019 Respirator requirements
24/34
Disinfect All Parts When the cleaner used does not contain a
disinfecting agent, respirator components
should be immersed for two minutes inHypochlorite solution (50 ppm of
chlorine) made by adding approximately
one milliliter of laundry bleach to oneliter of water at 43C/110F
7/29/2019 Respirator requirements
25/34
Or Use Liquid solution of iodine (50 ppm iodine)
made by adding approximately 0.8
milliliters of tincture of iodine (6-8 gramsammonium and/or potassium iodine/100
cc of 45% alcohol) to one liter of water at
43C/110F
7/29/2019 Respirator requirements

Also acceptable are Other commercially available
cleansers of equivalent
disinfectant quality when used asdirected, if their use is
recommended or approved by the
respirator manufacturer.

Rinse All Parts After Disinfecting Rinse components thoroughly in
clean, warm (43C/110F
maximum), preferably running,water.

Drain the parts The importance of thorough
rinsing cannot be
overemphasized. Detergentsor disinfectants that dry on
facepieces may result in
dermatitis.
7/29/2019 Respirator requirements

Disinfectant Note In addition, some disinfectants
may cause deterioration of
rubber or corrosion of metalparts if not completely
removed.

Reassemble & Test After Drying Reassemble facepiece,
replacing filters, cartridges, and
canisters where necessary.

YOUR respirator
The respirator you
use is designed to
protect your healthand life but only
if you use, clean and
store it properly
