1 INTRODUCTION

The North Model 7190N99 Respirator is a low-profile, air-purifying respirator
intended to be used for respiratory protection against particulate contaminants
not containing oil.

The Model 7190N99 has a large filter area to provide low breathing resistance.
The coaxial valve system prevents exhaling through the filter, prolonging the
filter’s useful life.

1.1 IMPORTANT INFORMATION

inants and their concentrations against which protection is required,
or a failure to follow North’s instructions and Warnings, as well as the
Cautions and Limitations contained within the NIOSH Approval Label
on the back page of these instructions will subject the user to the
risk of serious injury, illness or death from exposure to hazardous
materials.

2. Do NOT use this respirator under any of the following conditions:

• For protection against particulates containing oil.

• For protection against Arsenic, Asbestos or Lead in any concentra­tion.

• For protection against gases or vapors; or against unknown conta­minants.

• In atmospheres where the concentration of the contaminant
exceeds the respirator’s Maximum Use Concentration of 10 times
the contaminant’s permissible exposure limit established by applic­able OSHAor other government regulations.

• While performing or observing abrasive blasting (sandblasting)
operations.

• In oxygen-deficient atmospheres (any atmosphere having less than

19.5% oxygen by volume at sea level).

• In atmospheres where the concentrations of contaminant are
unknown, or are Immediately Dangerous to Life or Health (IDLH).
An IDLH atmosphere is any atmosphere which has a concentration
of any toxic, corrosive or asphyxiant substance that poses an
immediate threat to life, which would cause irreversible debilitating
effects on health, or which would interfere with the ability to escape
from a dangerous atmosphere.

• In confined spaces such as tanks, small rooms, tunnels or vessels,
unless the confined space is well ventilated and the concentration

WARNING (CONTINUED)

of toxic contaminants is known to be, and will continue to be,
below the Maximum Use Concentration recommended for this res­pirator.

• For fire fighting.

3. Do NOT use this respirator when conditions prevent a good face-

piece-to-face seal. For example:

i) the growth of beards, mustaches or sideburns which will pass

between the facepiece sealing area and the face;

ii) the use of spectacles, goggles or other devices which interfere

with the respirator;

iii)the use of head or face coverings which contain materials which

will pass between the facepiece sealing area and the face; and

iv)missing teeth or dentures, facial deformities or deep scars.

4. Immediately leave the contaminated area if:

i) breathing becomes difficult;
ii) dizziness or other distress occurs;
iii)you smell, taste or sense irritation from the contaminants; or
iv)the respirator becomes damaged.

5. Any air purifying respirator, when properly selected and fitted, will sig-

nificantly reduce, but will not completely eliminate, the breathing of
contaminant(s) by the respirator wearer. When working in atmos­pheres containing substances which are reported to cause cancer in
amounts below their permissible exposure standard, you will obtain
better protection from a continuous flow or positive pressure air sup­plied respirator.

6. This respirator does not provide protection to exposed areas of the

body. If the contaminated atmosphere contains vapors, gases or air­borne particulate matter which may either irritate or burn the eyes or
the skin, or can be absorbed by the body through penetration of the
skin, the use of specialized eye, hand and/or body coverings may be
required for protection.

G
L

I
S
H

Industrial Hygienist, or follow the hazard determination steps as outlined
in paragraph 7.2.2.1 of American National Standards Institute (ANSI)
Standard Z88.2-1992, American National Standard for Respiratory Pro-
tection.)

2) That this is the respirator approved for use against those contaminants
and at those concentrations. (Carefully read the NIOSH Approval Label
on the back page of this manual.) If you have any doubts prior to using
the respirator, consult an Industrial Hygienist, or North Safety Products
Customer Service in the United States at 1-800-430-4110 or 1-401-943­4400 or in Canada 1-888-212-7233 or 1-514-351-7233.)

3) That the contaminated atmosphere is not Immediately Dangerous to Life
or Health (IDLH). For the definition of IDLH see Warning #2 of the pre­ceding list of General Warnings.

4) That this respirator fits you properly. (See Warning #3 of the preceding
list of General Warnings and the section on Fit Testing.)

5) That you do not have any physical limitations or illness which would pre­clude you from using this respirator or which would be aggravated by an
increase in breathing resistance. (Ask your Safety Director or physician.)

You should not enter any potentially contaminated atmosphere unless
you have confirmed all of these factors.

1.1.4 TRAINING PROGRAM

These brief written instructions cannot substitute for a formal Respirator Train­ing Program. Such training should include an opportunity for you to handle the
respirator, learn how to inspect it, have it properly fitted, test its facepiece-to­face seal, wear it in normal air for a long familiarity period, and finally, to wear it
in a test atmosphere. The Training Program should be based on ANSI Z88.2­1992, and should familiarize you with OSHARegulation 29CFR Section

1910.134 and other regulations promulgated by various regulatory authorities.

46000532RB.5182 12/20/01 2:17 PM Page 7

1.1.5 FIT TESTING

Arespirator should not be assigned to a person unless the person is given a
qualitative or quantitative respirator fit test and the results of the test indicate
that the facepiece of the respirator fits properly.

Fit tests should be conducted at least annually and more frequently if there are
factors such as weight change or dental surgery which may affect the fit of the
respirator.

Instructions for carrying out qualitative and quantitative respirator fit tests are
given in publications such as ANSI Z88.2-1992, and respirator manuals pub­lished by government agencies such as NIOSH, ERDA, and NRC.

USER SEAL CHECKS (Facepiece-to-Face Seal Checks)

Each time that the respirator is put on and before each entry into a contami­nated atmosphere, as well as periodically while wearing the respirator in the
contaminated area, the respirator wearer should check the effectiveness of the
seal of the facepiece to the wearer’s face by carrying out a positive pressure
seal check. Instructions for carrying out a positive pressure seal check on this
respirator are given in the section of this manual titled TO PUTON THE RES­PIRATOR.

RESPIRATOR DESCRIPTION

This device is an air-purifying respirator consisting of a half mask facepiece
assembly and a replaceable filter which provide respiratory protection against
hazardous particulate matter. Other than filter replacement, no other mainte­nance can be performed on this respirator. The entire respirator must be
replaced when soiled or damaged.

When the respirator wearer inhales, the contaminated air is drawn through the
air-purifying filter, which removes the hazardous particulate matter from the air
before it enters the lungs. During inhalation, the inhalation valve in the face­piece opens and the exhalation valve closes to prevent contaminated air from
entering the facepiece. During exhalation, the exhalation valve opens and the
inhalation valve closes to prevent exhaled air from passing back through the
air-purifying filter.

The following should be performed in an area with uncontaminated air.

1. Remove your eyewear (if worn), then grasp the front of the respirator with
one hand and the upper headband with your other hand. Place the wide
portion of the facepiece under your chin. Position the narrow portion of
the facepiece on your nose bridge, and place the top headband above
your ears, on the back of your head. Place the bottom headband behind
your neck, below your ears, and adjust the position of the facepiece on
your face for best fit and comfort. (See Figure 1.)

FIGURE 1

Putting on the Respirator

2. The lengths of the headbands are adjustable. You may tighten the fit by
holding the respirator body with one hand and pulling on the elastic mate­rial in the appropriate direction with your other hand. To loosen, push out
on the retaining tab with a finger of one hand and pull the elastic material
back through the slot with the other hand.

46000532RB.5182 12/20/01 2:17 PM Page 9

3. Position the facepiece so that the nose section rests as low on the bridge
of your nose as is comfortable, and adjust the upper headband on each
sides just tight enough so that the respirator doesn’t slide down on your
nose. Do not over tighten. If the respirator pinches your nose, loosen
the upper headband slightly. Adjust the lower headband on each sides
just tight enough to secure the respirator under your chin. (See Figure 2).

FIGURE 2

Adjusting the Headband

NOTE

For proper positioning and comfort, the headbands should be adjusted
equally on both sides of the respirator, the upper headband should be
adjusted first, then the lower headband.

4. If you previously removed your eyewear, put it back on at this time.

5. Conduct a positive pressure user seal check as follows:

To conduct a positive pressure seal check, block the opening in the exhalation
valve guard using the palm of your hand and exhale slightly. If the facepiece
bulges slightly and no air leaks between the facepiece and your face are
detected, an effective seal has been obtained. If air is detected to be leaking
out between the facepiece and your face, reposition the facepiece on your face

4.1 SERVICE LIFE

The service life of this respirator will vary depending on the work environment.
Replace the filter after eight hours of use, or more frequently if used in a dirty

environment or if breathing becomes difficult.
The entire respirator should be replaced when soiled or damaged.

TO TAKE OFF THE RESPIRATOR

Go to an area with uncontaminated breathable air.
Loosen the headbands and remove the facepiece.

TURNAROUND CHECKS

After each use, the respirator should be examined by trained personnel.
Check for worn, damaged or missing parts and replace the entire respirator if

worn, damaged or missing parts are observed.
The respirator facepiece should be wiped with a North 7002 respirator wipe

pad to remove facial oils and loose particulates.
If used for eight hours, the filter should be changed. (See FILTER REPLACE-

MENT).

CAUTION

Do not attempt to repair or disassemble the respirator except to replace
the filter. The respirator is intended to be discarded when it becomes

STORAGE

Store in a clean dry area.

CAUTION

Elastomeric parts must be stored in a manner which will prevent them
from taking an abnormal set. Do not expose this respirator, during stor­age, to excessive heat (above 140(F/60(C), oil or airborne particulates.
Excessive heat may distort the facepiece resulting in the inability to
achieve a proper fit. Contaminated air can damage the filter. Either of
these conditions will expose the wearer to the risk of serious injury or
illness.
