1.1.3 USER REQUIREMENTS
To use this respirator you must know:
1) The contaminants and their concentrations. (Ask your
Safety Director or Industrial Hygienist or follow the haz-
ard determination steps as outlined in paragraph 7.2.2.1
of American National Standards Institute (ANSI) Stan-
dard Z88.2-1992,
American National Standard for
Respiratory Protection.
)
2) That this is the respirator approved for use against those
contaminants and at those concentrations. (Carefully
read the NIOSH Approval Label Summary booklet
included with this facepiece. Make sure the part num-
bers on the respirator components match the component
numbers on the NIOSH Approval Label or on the config-
uration chart. 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 1-800-430-4111 or 1-401-943-4400.)
3) That the contaminated atmosphere is not Immediately
Dangerous to Life or Health (IDLH). For the definition
of IDLH see Warning #4 of the preceding list of General
Warnings.
4) That this respirator fits you properly. (See Warning #5
of the preceding list of General Warnings.)
5) That you do not have any physical limitations or illness
which would preclude you from using this respirator or
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-to-face
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 Z88.2-1992, and should familiarize
you with OSHA Regulation 29CFR Section 1910.134 and
other regulations promulgated by various Regulatory
Authorities.
1.1.5 FIT TESTING
A respirator 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.
Both the 5400 Series and 7600 Series respirators are avail-
able in two sizes, medium/large and small. Most faces can
be fit with the medium/large, however some persons with
small faces may get a better fit with the small size.
Fit tests should be conducted at least annually or more
frequently if there are factors such as weight change or
dental surgery which may affect the fit of the respirator.
A fit test adapter is available for conducting quantitative fit
tests. (See Accessories.)
Instructions for carrying out qualitative and quantitative
respirator fit tests are given in OSHA 29 CFR §1910.134,
and respirator manuals published by government agencies
such as NIOSH, ERDA, and NRC.
1.1.6 PERIODIC SEAL CHECKS
Each time that the respirator is put on, before entering an
area containing hazardous atmospheres, and 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 negative or positive pressure seal check. Instructions for
carrying out user seal checks on this respirator are given in
Section 3 of this manual.
1.2 RESPIRATOR DESCRIPTION
This device is an air-purifying respirator consisting of a full
facepiece assembly and a pair of replaceable air-purifying
elements which provide respiratory protection against haz-
ardous vapors, gases and/or particulate matter, depending
upon the type of air-purifying elements used.
When the respirator wearer inhales, the contaminated air is
drawn through the air-purifying elements, which, depending
upon their type and class, remove the hazardous vapors,
gases and/or particulate matter from the air before it enters
the lungs. During inhalation, the inhalation valves in the
facepiece open and the exhalation valve closes to prevent
contaminated air from entering the facepiece. During exha-
lation, the exhalation valve opens, and the inhalation valves
close to prevent exhaled air from passing back through the
air-purifying elements.
This respirator is approved by NIOSH to protect against, and
reduce exposure to the type of air contaminants specified on
the air-purifying elements and in the approval label supplied
with the respirator or the air-purifying elements. Use of the
Back Pack accessory allows the wearer to place the air-puri-
fying elements on his back. See Section 10 for a list of
approved accessories.
