1.0 Purpose
The purpose of this Respiratory Protection Program is to establish safety guidelines for
Clarkson University employees who may be exposed to airborne respiratory hazards on
the job. The use of a respirator is required only when engineering and administrative
controls fail to maintain airborne contaminants at or below human exposure limits.
2.0 Scope and Applicability
The respiratory system provides the most direct route of human exposure to toxic,
airborne materials. This Respiratory Protection Program applies to employees who, as a
result of his/her job duties, may be exposed to hazardous environments where
contaminants exceed the human exposure limits or that regulatory authorities have
determined to be immediately dangerous to life and health.
This program presents guidelines for the use of respiratory protection and includes
provisions for training, hazard assessments, respirator selection, medical monitoring, fit
testing, record keeping, and equipment care and storage. This program also details the
responsibility for Managers, Supervisors, competent persons and employees.
3.0 Reference

The Occupational Safety and Health Standards for General Industry (29 CFR
1910.251 - 1910.257).
4.0 Program Mission
To provide a place of employment free from recognized hazards that may cause or are
likely to cause death or serious physical harm to employees or the public. When
respiratory hazards exist in the work place that cannot be eliminated by administrative
and engineering controls, the Respiratory Protection Program will be implemented. Only
NIOSH approved respiratory protection equipment, provided by the University, will be
used.
5.0 Definitions

6.0 General Provisions
6.1 Training
Mangers and Supervisors will assure that training is provided to each employee prior to a
task/assignment that may require the use of a respirator. Training shall include:










Review of the Clarkson University Respiratory Protection Program
Identification of respiratory hazards that may be encountered on the job
Purpose/application of respirators
Proper selection and use of respirators
Limitations of respirators
Maintenance and care of respiratory protective equipment
Fit testing
Inspection
Medical conditions potentially limiting the effective use of respirators
Medical monitoring program
Employees should be trained annually and are required to demonstrate their
understanding through a written test and/or hands on exercises. Employee training shall
be documented on a Training Attendance Form.
A written copy of this program will be available for employee review upon request.
6.2 Hazard Assessment
The purpose of a Hazard Assessment is to determine if hazards exist which would
endanger employees assigned to a job or work area, and what methods or best practices
may be available to neutralize or eliminate those hazards.
A competent person(s) shall perform a hazard assessment and make recommendations for
administrative or engineering controls. Where administrative and/or engineering controls
will not reduce employee risk to an acceptable level, the hazard assessment shall include
recommendations for PPE and/or special procedures that may further assure safety.
Employee exposure assessments shall consider air monitoring, process information, the
physical work environment, historical data, and best practices relative to the type of
hazard. With regard to specific airborne contaminants, the proper respirator and
cartridges shall be selected to control exposures above the Threshold Limit Value (TLV).
Page 5 of 17
The TLV of an air contaminant does not have to be exceeded for an employee to use a
respirator. The employee may request the use of a respirator because of a nuisance
exposure or for personal reasons. However, if exposure limits are exceeded, mandatory
use of respiratory PPE is not negotiable.
Clarkson University’s Respiratory Protection Program is limited to the use of half face air
purifying cartridge type respirators. Any use of air supplied or full face respirators
designed for use in atmospheres of less than 21% oxygen is beyond the scope of this
program and is therefore prohibited. Likewise, use of respirators for entry into an
atmosphere where airborne concentration may exceed 25 percent of the lower explosive
limit is prohibited.
6.3 Respirator Selection
The common types of cartridges used on air purifying respirators at Clarkson are:


P100, Organic Vapor
Combination P100/OV/Acid Gas- welding with fluxes containing acids
Only the National Institute of Occupational Safety and Health (NIOSH) approved type
respirators and cartridges shall be used by Clarkson employees to protect themselves
from airborne contaminants. The respirators and cartridges shall be selected to provide
the adequate protection from specific airborne contaminants in concentrations above the
established TLV for substances known to be present.
6.4 Purchasing
6.2.8 Purchasing
Only NIOSH approved type respirators shall be purchased and kept in stock along with
an adequate supply of cartridges, replacement parts, and cleaning supplies. Unapproved
respirators shall be removed from inventory. To maintain consistency throughout the
University, the Environmental Health and Safety Committee recommends North brand
respirators be used.
6.5 Medical Monitoring
6.2.9 Medical
Employees who may be required to wear a respirator must first be medically certified to
do so. A Medical Evaluation will be scheduled by the University for each employee so a
Physician or Other Licensed Health Care Professional may determine if they are fit to
wear a respirator as part of their job. Any employee refusing the medical evaluation will
not be allowed to work in an area or on a job where a respirator is required and may be
subject to discipline. Follow-up or additional medical evaluations may be required as
determined by the Physician. The University will provide additional evaluations if:
Page 6 of 17
1. An employee reports new medical conditions, signs or symptoms that could
impact his/her ability to use a respirator;
2. A Physician, informs the University that an employee needs to be reevaluated;
3. Observations made during fit testing or program evaluation, indicate a need
for employee reevaluation;
4. A change occurs in workplace conditions that may result in a substantial
increase in the physiological burden placed on an employee; and/or
5. An incident resulting in over-exposure to a chemical/contaminant or an
employee showing signs of over-exposure to a chemical/contaminant.
6.6 Fit Testing
Fit testing is required for employees required to wear respirators. The employee must be
fit tested with the exact make, model and size of respirator that will be used on the job.
Fit testing of cartridge filter respirators shall be accomplished by performing quantitative
or qualitative fit testing under positive and negative pressure. Fit testing may not be done
until employees are cleared to wear a respirator by a Physician.
Employees are prohibited from wearing a respirator under conditions that might prevent
them from achieving a good face seal such as: certain styles of facial hair, interference
by corrective eye wear, or the absence of one or both dentures. Clean-shaven skin under
the respirator sealing surfaces is a must, even a mild growth of whiskers might interfere
with this seal.
Fit testing will be done annually as well as any time there are changes in the employees
physical condition that could affect the fit (i.e. significant weight gain or loss, facial
scarring).
Seal checks of the respirator:
The individual who uses a tight-fitting respirator is to perform a user seal check to ensure
that an adequate seal is achieved each time the respirator is put on. Both the positive and
negative pressure checks listed below shall be used.
A.
Positive pressure seal check
Close off the exhalation valve and exhale gently into the face piece. The face fit
is considered satisfactory if a slight positive pressure can be built up inside the
face piece without any evidence of outward leakage of air at the seal.
B.
Negative pressure seal check
Close off the inlet opening of the canister or cartridge(s) by covering with the
palm of the hands. Inhale gently so that the face piece collapses slightly, and hold
the breath for ten seconds. If the face piece remains in its slightly collapsed
condition and no inward leakage of air is detected, the tightness of the respirator
is considered satisfactory.
Page 7 of 17
6.7 Recordkeeping
6.2.7
Records shall be maintained by the Safety Office on each employee who participates in
the respiratory protection program. A sample medical questionnaire and sample
physician’s evaluation form are included in the Appendix. The completed medical
questionnaire is confidential and when completed should be given to the physician at the
time of medical evaluation. A physician’s evaluation concerning the employee’s ability
to wear a respirator will be issued by the physician to the Clarkson University Safety
Office. The physician’s evaluation and fit testing records will be kept by the Safety
Office.
6.8 Respirator Care
Clarkson University employees are responsible for maintaining their respirator, which
includes cleaning the respirator, changing filters or cartridges, and inspection.
Employees will take care of their respirator as follows:
Inspection:
The wearer of a respirator will inspect it prior to each use and check for proper fit, usage,
and condition. The use of a defective respirator is prohibited. If a defective respirator is
found during inspection, it must be repaired with manufacturer parts or returned to the
stockroom for replacement. Worn or deteriorated parts will be replaced prior to use.
Respirators are to be properly maintained at all times in order to ensure they function
properly and adequately protect the employee.
Before each use, the respirator will be inspected by the wearer for the following:
Inspection Procedure:
1.
Check for worn or frayed straps.
2.
Look for wear or damage on the seal of the face piece.
3.
Be sure all parts are tight.
4.
Check rubber and plastic parts for flexibility.
5.
Valves should be clean and seated perfectly.
6.
Be sure filters and cartridges are the right kind for the atmosphere in
which work is to be done.
7.
Review entire respirator for cleanliness and missing parts.
Change Schedule:
Employees wearing air-purifying respirators shall change the cartridges on their
respirator if they begin to experience difficulty breathing or note the odor of a potential
contaminant.
Cleaning Procedure:
Respirators will be cleaned after each use. Each employee shall clean their own
respirator. When cleaning a respirator, remove filters, cartridges, valve assemblies, and
any other detachable parts. Clean and dry each part of the respirator and inspect it
carefully to be sure it is in good condition before reassembling. Follow the
Page 8 of 17
manufacturer's instructions for cleaning and disinfecting the respirator. Generally, a mild
detergent and soft brush are used for cleaning. Rinse the respirator thoroughly
in
clean, warm water. Rinsing is extremely important because a residue of the cleaning
agent can damage the respirator and cause skin irritation the next time the respirator is
worn. Use a soft, lint-free cloth to absorb most of the water. Be sure all parts are
thoroughly dried before reassembling the respirator.
Repair:
Respirators that do not pass inspection will be removed from service and will be
discarded or repaired. Repair of the respirator must be done with parts designed for the
respirator in accordance with the manufacturer’s instructions. No attempt will be made to
replace components or make adjustments, modifications or repairs beyond the
manufacturer’s recommendation.
Storage Procedure:
The respirator should be placed in the storage area in such a way that no part of it will be
stretched, bent, or compressed. Do not put anything on top of it that will affect its shape.
Respirators stored incorrectly can easily become distorted and develop leaks. The
respirator and cartridges must be stored in separate air-tight containers to prevent
contamination. When storing a respirator, even overnight, first flex the rubber parts to
make sure they are not twisted or bent. Store the respirator where it will be protected
from the following elements:
 Physical Damage
 Sunlight
 Extreme Heat
 Dust
 Extreme Cold
 Moisture
 Damaging Chemicals
Failure to properly care for and maintain an assigned respirator can jeopardize the
respirator’s effectiveness to protect against the containment or hazard.
