University of New Mexico in accordance with Occupational Safety and Health
Administration (OSHA) regulation 29CFR 1910.134. The program ensures those personnel required
to wear respiratory protection are medically cleared, trained and fit tested
with the proper respirators.
A. SCOPE
Employees
required to wear a respirator at the
B. DEFINITIONS
Cartridge/Canister – A container with a filter, sorbent, or catalyst, or
combination of these items, which remove specific contaminants from the air
passed through the cartridge or canister.
Dust -
Material created when solid material breaks down or is crushed to produce fine
air-borne particles.
Employee - Any person who receives compensation from the University for his/her
work.
Facepiece – The portion of the respirator that covers the face.

prohibited by OSHA regulations from wearing all respirators except for
loose-fitting, hood type PAPRs.
1. All employees
required to wear a must be medically evaluated by EOHS prior to training,
fit-testing and use of the respirator.
Employees using respirators on a voluntary basis must be medically
evaluated by EOHS prior to being provided a respiratory by their
supervisor. Employees will fill out a
medical questionnaire and, if necessary, complete additional screening at the
discretion of the PLHCP. A written medical determination of the employee’s
ability to wear a respirator will be provided to the employee’s supervisor.
This evaluation will be provided to UNM employees free of charge.
2. Frequency
a. Additional medical evaluations will be performed if an
employee reports medical signs or symptoms that are related to their ability to
use a respirator.
b. Observations made during fit testing or periodic program
evaluation indicates that an employee needs to be re-evaluated.
c.
A change occurs in the
workplace conditions that may result in a significant increase in physiological
burden on the employee.
d.
When the EOHS provider,
supervisor or program administrator informs the employer that an employee
should be reevaluated.
e.
All employees who may
use a respirator in Immediately Dangerous to Life and Health (IDLH) scenarios
must be medically certified on an annual basis.
1.
Respirators will be
selected based on the respiratory hazards to which employees are exposed. With the assistance of SHEA, supervisors will
identify the potential respiratory hazards in their work area. SHEA will evaluate the respiratory hazards in
the workplace and determine which respirator and cartridges are
appropriate. This evaluation will
include workplace conditions, chemicals used and a reasonable estimate of the
concentrations of the chemicals. Air
monitoring for the contaminant will be conducted as deemed necessary by SHEA.
2.
All respirators,
including disposable particulate respirators (N,R, or P-95, 99, or 100
filtering facepieces), used at the University of New Mexico must be NIOSH
approved. Prohibited are masks such
as the 3M 8500 Comfort Masks, or any other unapproved nuisance dust mask
offered for sale by any other manufacturer.
3.
A sufficient number of
respirator models and sizes are available at SHEA to ensure that a respirator
is acceptable to, and correctly fits, the user.
1.
Standard Operating Procedures (SOPs)
Supervisors,
with the assistance of SHEA, will be required to develop area-specific standard
operating procedures (SOPs) that list what procedures require respiratory
protection. These SOPs must also list
the appropriate respirators and cartridges/filters for each procedure. Templates for these SOPs are available in
Attachment A.
2.
Fit-Checks
Employees
will perform user fit-tests each time they put on their respirators:
a. Exhaust Valve Positive Pressure Test: Place palm over the exhalation valve in front
of the mask and exhale gently to cause a slight positive pressure buildup
inside of the facepiece. If leakage is
detected, reposition the respirator on the face and/or adjust the tension of
the headbands to eliminate leakage.
Repeat test. If the facepiece
bulges slightly and no air leakage is detected around the edges or around the
nose, a positive fit has been achieved..
b.
Negative Pressure Test: Place palms of hands over the
cartidges and/or filters, inhale gently so that the facepiece remains in a
slightly collapsed condition. If air
leakage is detected, reposition the respirator on the face and/or adjust
tension of the headbands to eliminate leakage.
If the facepiece remains in a slightly collapsed condition and no inward
leakage of air is detected, the fit is considered satisfactory.
3.
Air-Purifying Respirator Limitations
Half-face,
full-face and powered air-purifying (PAPR) respirators are air-purifying
respirators. These respirators use a
cartridge/filter to remove a specific contaminant from the air that the wearer
is breathing. Air-purifying respirators
only protect against the hazards that the cartridge/filter is designed to
remove. The cartridges/filters have a
limited life span and must be changed regularly, based on a designed changout
schdule or if exposure symptoms are experienced. Air-purifying respirators must not be used in
an oxygen deficient atmosphere.
a.
Filtering facepiece
respirators (N-95) are not to be used for paint spray, gases, vapors, asbestos,
or sand-blasting, as these masks provide only limited protection from very
small dust particles, gases, vapors, mists, and aerosols.
b.
Tight fitting
respirators (half or full face) cannot be used if the employee has a beard or
facial hair that interferes with the face to respirator seal.
c.
PAPR (powered-air
purifying respirator). This type of
respirator, with a loose-fitting hood
attachment, can be used by employees that have beards or other facial hair. PAPRs with a tight-fitting facepiece will be
fit tested in the negative pressure mode.
1. IDLH
Atmospheres
IDLH
atmospheres include:
·
Atmospheres in which the
contaminant concentration exceeds the IDLH concentration or is unknown but may
be life threatening; and/or
·
Oxygen-deficient
atmospheres
If
employees are required to enter an IDLH atmosphere, the buddy system must be
followed. Entry will only occur with two
persons entering the IDLH environment and with at least one person located
outside of the IDLH atmosphere. Visual,
voice or signal line communication must be maintained between the persons
inside and the person outside. The
employee located outside must be trained and equipped with the same level of
respiratory protection to enable him/her to provide emergency rescue, if
necessary.
2. Procedures
To Ensure Adequate Air Quality, Quantity, And Flow Of Breathing Air
a.
All compressed breathing
air will meet the ANSI/CGA requirements for Grade D breathing air (G-7.1-1989).
b.
Purchased cylinders used
to supply breathing air must be tested and maintained as described in the
Shipping Container Specification Regulations of the Department of
Transportation (49 CFR part 173 and 178) and must not be more than 15 years
old.
c.
Breathing air couplings
must be incompatible with outlets for nonrespirable worksite air or other gas
systems.
All
personnel working in job classifications identified as requiring negative or
positive-pressure respirators will be educated on the use of their respirators
and will be qualitatively or quantitatively fit tested at least annually for
the same make, model, style. size, and type of respirator they have been issued.
Only those personnel who have been trained and fit-tested are authorized to use
respirators. No employee will be fit
tested or allowed to wear a respirator with a beard or facial hair that
interferes with the face-to-facepiece seal or interfees with valve
function. Additional fit testing is
required if there are significant changes (i.e. facial scarring, dental
changes, cosmetic surgery, or an obvious change in body weight) in the
employee’s physical condition that may affect the respirator fit.
The
respective supervisors will be notified by memo when training and fit-testing
is required for their employees.
Training dates will be provided at that time. Supervisors are responsible for ensuring that
their employees are scheduled for a class.
Until SHEA has determined
that the exposure is below the action level, particulate respirators must be
fit-tested. All air-purifying and
particulate respirators must be NIOSH certified.
See
Attachment B for Fit-Testing Procedures.
Voluntary
Use
Fit-testing
is not required for particulate respirators (filtering facepieces) as set forth
in 42 CFR 84 if the following conditions are met:
a.
The exposure level has
been evaluated by SHEA and it is determined that the level of exposure to the
contaminant is below the PEL or TLV for the contaminant; and,
b.
The use of the
respirator does not itself pose a hazard.
1.
Cleaning and Disinfecting
a. The
maintenance and cleaning program must ensure the requirements provided in the
manufacturer’s inspection procedures are adhered to as a minimum acceptable
program.
b. The
actual cleaning and maintenance of a collective/multiple use respirator may be
performed by the individual using the respirator or the task may be assigned to
the section responsible for the storage and issuing of collective use
respirators. Respirators used by more
than one employee will be cleaned and disinfected before being worn by a
different individual.
c. Individually
issued respirators shall be cleaned and disinfected by the assigned user as
often as necessary to be maintained in a sanitary condition.
d. Respirators maintained
for emergency use shall be cleaned and disinfected after each use.
e. Respirators
used in fit testing and training shall be cleaned and disinfected after each
use.
f. Procedure
for Cleaning:
·
Remove filters,
cartridges, or canisters. Disassemble
facepiece by removing components such as valve covers and diaphrames, or other
components as recommended by the manufacturer.
Replace defective parts if necessary, or call SHEA for assistance with
repair.
·
Wash components in warm
(110o F maximum) water with a mild detergent or with a cleaner
recommended by manufacturer. A soft
bristle brush (not wire) may be used.
·
Rinse all components
thoroughly with clean, warm water.
Drain.
·
Air dry in a clean
area. Excess water may be absorbed by a
clean paper towel. Do not use hair
dryers or compressed air to speed the drying process.
·
If the cleaner doesn’t
contain a disinfecting agent, respirator components should be immersed for two
minutes in a fresh solution of one (1) part bleach in 1000 parts water.
·
Rinse parts thoroughly
in clean, warm water. Drain.
·
Allow them to air dry or
wipe dry with a paper towel or clean, lint-free cloth.
·
Reassemble and place the
facepiece in a “ziplock” type plastic bag for storage.
Respirators must be stored in a clean and sanitary
condition. The respirator must be
completely dry before storage.
·
Never use alcohol to
clean the respirator. Alcohol will dry the respirator surface and cause
immediate deteriation.
2.
Storing
a. Do not store
respirators and parts near or in:
·
Dusty areas. Dirty respirators can cause dermatitis. OSHA regulations require that respirators be
stored in a clean and sanitary condition.
·
Direct sunlight. Excessive heat will deform the respirator and
prevent it from having a good face to mask seal.
·
Temperature
extremes. Excessive heat will deform the
respirator and prevent it from having a good face to mask seal. Excessive cold can cause cracks in the facepiece
causing leaks.
·
High humidity
areas. Extremely humid conditions will
make it difficult to maintain a good mask to face seal.
·
Toxic chemicals. Toxic chemicals can cause dermatitis or
facial burns.
b. Store
the respirator in such a manner as to prevent the facepiece from being
deformed. Do not hang the respirator
from the straps. Respirators should be stored face down to prevent bowing or
deformation of the inhalation valves.
c. Store the filters,
cartridges or canisters separately from the facepiece. The weight of these can deform the respirator
over a period of time. These components
should also be stored in a “ziplock” type plastic bag to prevent passive
absorption.
3.
Inspecting
a.
All respirators must be
inspected before and after each use and at least monthly.
b.
Check all parts for wear
and defects. Inspect the head band, mask, valves, connecting tube and
cartridges for deterioration. Rubber
parts should be checked for elasticity and cracks. Stretching and manipulating rubber parts when
stored for several weeks will help prevent deterioration. The valves should be inspected for tears and
any obstructions to proper sealing.
c.
Check approval sticker
(TC#) on filters, canisters or cartridges to verify that the right canister,
filter or cartridge is being used for the hazard encountered.
d.
Replace filters,
canisters or cartridges when change-out schedule indicates or if physical
symptoms are noticed.
e.
When a mask is used only
for emergencies, a record of monthly inspections with dates, findings and
corrective actions shall be maintained by the owning department.
4.
Repairing/Discarding
a. Only
qualified personnel shall replace parts.
b. Only
manufacturers parts designated for that use shall be used. Parts are not interchangeable between
manufacturers. Mixing of different
manufactuer’s parts voids the certification of the respirator and may adversely
effect the function of the respirator.
c. Head
straps must be replaced when damaged or
when the elastic becomes defective. All
other repairs must be made by SHEA or the manufacturer.
f.
If the respirator is
damaged beyond repair or if the facepiece becomes distorted, it must be
discarded immediately.
g.
Filtering facepieces
should be discarded if they are damaged in any way, if they become excessively
dirty or contaminated, or if they become difficult to breathe through.
5.
Replacing Filters/Cartridges
A schedule will be
developed for each area, with the assistance of SHEA, for replacing
filters. The schedule will be based on
the concentrations of air contaminants and the frequency of use.
6. Respirator Inspection, Cleaning and
Maintenance
Supervisors should audit respirator usage periodically
to insure that respirators are being maintained properly by those employees
required to utilize respirators for protection.
Every
University employee required to wear respiratory protection will receive
Respirator Training PRIOR to
respirator use. This training will be
provided by SHEA. It will include the
following:
·
Requirements of the
Respiratory Protection Standard;
·
Why the respirator is
necessary and how improper fit, usage or maintenance can compromise the
protectiveness of the respirator;
·
What the limitations and
capabilities of the respirator are;
·
What to do if the
respirator malfunctions or if the employee becomes ill while wearing it;
·
How to inspect, put on,
remove, use and check the seals of the respirator;
·
How to maintain and
store the respirator; and
·
How to recognize medical
signs and symptoms that may limit the effective use of a respirator.
Employees
will be required to demonstrate that they understand how to wear the
respirator.
Employees
choosing to voluntarily wear a respirator will be provided a copy of 29CFR
1910.134, Appendix D “Information for Employees Using Respirators When Not
Required Under Standard” by their supervisor, or by EOHS following medical
clearance. No other requirements
specified in this program apply to voluntary use, except for sanitary storage
of respirators.
In
addition to the Respirator Training provided by SHEA, employees must be
provided with area-specific training.
This training is to be conducted by the supervisor and will inform the
employees of the following:
·
Procedures in their work
area that require respiratory protection;
·
Areas available for
storage and cleaning of respirators;
·
When cartridges/filters
must be discarded; and
·
Where employees can get
new cartridges/filters.
Respirator
Training will be conducted prior to the employee’s use of any respirator and
annually thereafter. Retraining will
also be conducted if there is any indication that the employee cannot
demonstrate that he/she has the understanding or skill to use a respirator.
Supervisors
are responsible for ensuring that employees that are required to wear
respirators are trained annually.
All
training is documented and maintained by SHEA.
L.
PROCEDURES FOR REGULARLY EVALUATING THE RESPIRATORY
PROTECTION PROGRAM
The Respirator Site
Evaluation Form, Attachment C, will be used to document evaluations of the
effectiveness of the respiratory protection program. SHEA will observe employees using their
respirators and will ask questions to ascertain their knowledge of respirator
use..
This
information will be evaluated and the program will be modified as necessary.
M. Safety Precautions
Before
starting any hazardous operations, be sure to employ the following safety
measures:
a. Be
sure the respirator functions properly.
b. Do
not perform any hazardous duties unless you are medically cleared, properly
trained and fit-tested.
c. When
the wearer detects a resistance in breathing, a taste, an odor, smells the
chemicals being used or an extra effort is needed to inhale, they shall vacate the hazardous area
immediately.
·
DO NOT remove the respirator
until out of the hazardous area because it still offers some protection.
·
DO NOT reenter the hazardous
area until the cause of the problem is identified and repaired.
