1.4  DEFINITIONS

Air Purifying Respirator - A respirator in which ambient air is passed through
an air-purifying element that removes the contaminant(s). Air is drawn through
the air-purifying element by means of the breathing action. These types of
respirators are variously called disposable air purifying, particle removing,
dust masks, cartridge type, negative pressure, and air purifying.

Confined Spaces - A space that, by design, has limited openings for entry and
exit, could have unfavorable natural ventilation that could contain or produce
dangerous air contaminant levels, and is not intended for continuous employee
occupancy.

Contaminant - A harmful, irritating, or airborne nuisance material present in
ambient air.

Disposable Respirator - A respirator for which maintenance is not intended and
is designed to be discarded after excessive resistance to breathing develops,
there is sorbent exhaustion, physical damage, it is soiled from use, or end
of service life renders it unsuitable for use. At a minimum, these respirators
shall be approved for toxic dusts. Nuisance dust respirators shall not be
permitted.

Engineering Controls - These are the preferred methods of control of exposure
to contaminants. They may include, but not be limited to any of the following
or a combination of local exhaust ventilation, enclosures, isolation, and wet
methods.

Exposure Limit - The maximum allowable concentration of a contaminant in the
air to which an individual may be exposed. These concentrations may be time-
weighted averages, short-term limits, or ceiling limits.

Immediately Dangerous to Life or Health (IDLH) - Any atmosphere that poses an
immediate hazard to life or poses immediate irreversible debilitating effects
to health.

Powered Air-Purifying Respirator (PAPR) - A respirator in which ambient air
is drawn through an air-purifying element that removes contaminant(s). Air
is drawn through the air-purifying element by means of a battery operated
blower. These can be half or full face or hoods and provide air under positive
pressure.

Pressure-Demand self-contained Breathing Apparatus (SCBA) - An atmosphere
supplying respirator in which the breathing air is carried by the wearer in
a cylinder. Such a respirator maintains a constant positive pressure within
the faceplate supplying additional breathing air when the positive pressure is
reduced inside the faceplate by inhalation.

Qualitative Fit Test - A pass or fail fit test that relies on the subject's
sensory response to detect the test material, such as irritating smoke
or banana oil, and therefore tests the effectiveness of the respiratory
protection.

Quantitative Fit Test - A fit test that uses an instrument to measure
the challenge agent and, therefore, the effectiveness of the respiratory
protection. A numerical protection factor is determined for each respirator
user.

2  PROGRAM REQUIREMENTS

2.1  RESPIRATOR SELECTION

Respirator selection shall be according to the following criteria:

o  Be based on hazard(s) to which employees are or may be exposed.

o  Be appropriate for the specific hazard and only for use in specified
locations.

o  Selection considerations shall be defined and include, but not be limited to
the following: (See Appendix A.)

Determined prior to respirator selection and periodically reviewed during
respirator use

Type and concentration of air contaminant

Location, frequency, and physical aspects of the job

o  Available Respirator Types: The type, concentration of contaminant present,
and situation will determine the type of respiratory protection required.
This equipment shall be used under the conditions for which it was designed
and approved.

Disposable Air Purifying Masks or Dust Masks are single-use disposable
respirators. They shall, at a minimum, be approved for toxic dusts.

Air Purifying, Cartridge/Canister, and Negative Pressure Respirators
consist of a full- or half-face mask and are equipped with cartridges
specific to the contaminant that is present.

NOTES ON AIR-PURIFYING RESPIRATORS

The proper choice of the cartridge or canister is critical. The
use of the wrong cartridge or canister will cause the wearer to be
unprotected.

They shall not be used under IDLH conditions.

They shall not be used in atmospheres where the concentration of
oxygen is less than 19.5% by volume.

They shall not be used in atmospheres where the manufacturer's
recommended maximum use concentration of the cartridge will be
exceeded.

Chemical/cartridge or canister respirators shall not be used for
protection against air contaminants that cannot be detected by odor or
irritation at concentrations below the occupational exposure limit, or
for which olfactory fatigue may occur rapidly at high exposure levels.

Chemical cartridges or canisters shall be approved for the particular
contaminant of concern.

Powered Air-Purifying Respirator (PAPR) is similar, in function, to
negative pressure cartridge respirators.  The difference being that air
is mechanically filtered rather than being drawn through the filters by
breathing action. See above "Notes on Air-Purifying Respirators."

Pressure-Demand self-contained Breathing Apparatus (SCBA) consist of a
full-faceplate mask attached to a fully portable compressed breathing
air tank worn by the user. SCBAs to be used in an emergency response
only shall be wall mounted or otherwise easily available in pairs near
where they may be needed. SCBAs may also be required for non-routine
tasks, such as confined space entries. Designated SCBAs may be used for
non-routine operations potentially involving oxygen deficient atmospheres
and IDLH conditions.

Special Site or Process Requirements may justify the need for other types
of respiratory protection. These types of respirators may include:

o  Supplied air pressure demand airline

o  Supplied air pressure demand airline with escape SCBA (Hip-pak)

o  Supplied air continuous flow.

o  EH&S must approve the use of these types of equipment and will detail
any special precautions.

2.1.1  Issuance of Respirators

The following restrictions apply to the issuance of respirators.

o  Respirators shall only be issued to those employees approved by 
EH&S.  Anyone issuing respirators must check the approval list first.

o  SCBAs shall be used for emergency response and other
specifically predesignated tasks.  Regardless of the application,
certification is required for the use of SCBAs.

o  Medical staff may be cleared by the College physician for N95 masks only.

2.2  HAZARD EVALUATION FOR RESPIRATOR SELECTION

Respirator usage shall be based on the review of an operation or location with
the potential for actual exposure to harmful levels of contaminants in the work
environment.

The evaluation of a hazard shall be conducted before commencing a routine
or non routine task that has the potential to require the use of respiratory
protection.

Respirators shall be used only with prior (EH&S) authorization until feasible
engineering controls can be instituted. Situations include, but are not limited
to the following.

o  In response to an existing condition.

o  In the event of a process change that could potentially generate unknown
levels of workplace environmental contaminants.

o  In response to complaints regarding chemical odors, irritation, or other
symptomatic factors that indicate unknown and potentially excessive levels
of airborne chemical vapors, mists, fumes, gases, or particulate are present
in the work environment.

o  For a designated and required emergency response activity.

Prior to the issuance of a respirator, an evaluation of the environment in
question shall be conducted by department management or supervision and EH&S to
determine whether respirators shall be required. The evaluation shall include,
but not be limited to, a review of the following areas. (See Appendix A.)

o  The work area including its size, equipment layout, the type of ventilation
and its effectiveness, additional contaminant control measures, and the
general environmental conditions

o  Employee activity including the number of people involved, job routines,
work location, amount of time spent in the area, and work rates

o  Known potential inhalation hazards including chemical components, type of
contamination, and toxicity and occupational health hazard data

o  Available industrial hygiene data including measurements of levels of
contaminant performed by a competent person

Respirators shall not be used in lieu of feasible engineering controls that
may include, but are not limited to local exhaust ventilation, enclosures,
isolation, and wet methods.

2.2.1  Mandatory Use of Respiratory Protection

o  A list of  construction (shop), maintenance, and emergency response activities that
require the use of respiratory protection shall be developed and
maintained by EH&S.

o  Specialized programs for construction, maintenance, and emergency activities
that require the unique use of respiratory protection shall be developed and
maintained.

2.2.2  Authorized Use of Respirators

o  Employees may elect to request the use of a respirator for certain
maintenance activities for which the use of a respirator
is not mandatory.

o  Authorization shall be obtained from the EH&S.

o  A list of construction, maintenance, and emergency response activities where
respiratory protection is authorized shall be developed and maintained.

o  Such use of respirators shall comply with all requirements of the written
Respiratory Protection Program.

o  Non mandatory use of respirators is discouraged.

2.2.3  Other Uses for Respirators

A requirement for temporary, non routine use of respirators may arise. The
requirement shall be added to the documented list of activities where
temporary, non routine use is either required or authorized.

2.3  RESPIRATOR CERTIFICATION-TRAINING AND FIT TESTING

Respirator users shall be certified as having successfully fulfilled medical
evaluation, training, and fit testing requirements prior to respirator use.

2.3.1  Requests for Certification

o  Individuals requiring or requesting certification to use a respirator shall
first notify their Manager/Supervisor.

o  A Manager/Supervisor is responsible to ensure
that employees are wearing the proper respiratory protection while
performing tasks that require mandatory or authorized respiratory protection.

o  The employee must have current respirator medical approval before attending
required respirator training and fit testing.

o  Certification with the associated training, medical clearances, and fit
testing shall be required upon initial assignment and, thereafter, at least
annually or sooner should the conditions of use change, or there is a change
in the physical condition of the user.

2.3.2  Medical Approval

Medical evaluation is required prior to employee certification and use of
respiratory protection in accordance with this policy.   

Certain usage of respiratory protection does not require medical evaluation. 
Exceptions are determined by EH&S on a case by case basis, such as for the
non-mandatory use of  dust respirators or  N95 masks for Medical personnel.

The doctor will certify the employees ability to wear a respirator.
All medical information collected as part of this exam will be kept confidential.

Recommendations regarding use of respirators will be communicated to the
EH&S Coordinator. 

Doctor’s exam required on initial application and every five years thereafter for negative pressure respirators.  SCBS require an annual exam.  Employee will certify medical condition annually or when there is a change in medical condition that could have an adverse effect on wearing a respirator.

*Upon completion of the exam, the doctor can notify EH&S of the
results via the Respirator Evaluation Notification form (see appendix).

Employee health issues that may arise during the course of respirator use will
be managed by EH&S and recommendations will be made regarding
continued ability to use respirators.

2.3.3  Training

Training shall be documented and presented to the appropriate groups.

Note to Physician

The Occupational Health & Safety Administration (OSHA) and Vermont OSHA (VOSHA) permits the use of respirators under their regulation 29 CFR 1910.134  in the control of those occupational diseases caused by breathing air contaminated with harmful dust, fogs, fumes, mists, gases, smoke, sprays, or vapors.

The regulations also state that persons should not be assigned to tasks requiring use of a respirator unless it has been determined that they are physically able to perform the work and use the equipment.  The local physician shall determine what health and physical conditions are pertinent at the time of application.  The respirator user’s medical status should be reviewed periodically with the employee by the safety officer after physician’s initial exam.

Since our employee, your patient, comes under these regulations we are requesting a medical evaluation for the use of a half face/full face negative pressure or a positive pressure self contained breathing apparatus (SCBA)  or Positive Air Pressure Respirator (PAPR) as indicated on the front of this form.

Any questions may be direct to my attention at  443-5726

MIDDLEBURY COLLEGE
SCBA INSPECTIONS

Self-contained breathing apparatus (SCBA).  Requiring monthly inspections, making sure the air and oxygen cylinders that are available for immediate use are maintained in a fully charged state (i.e., pressure is not below 90% of the manufacturer’s recommended level).  You must also activate the regulator and low pressure warning devices to ensure that they function properly.

Emergency use respirators.  Inspect at least monthly, checking for proper functioning before and after each use.  When inspecting these types of respirators you must:
1.  Document the date of inspection, name or signature of inspector, inspection findings, any remedial action required, and serial number or other identification of the respirator.
2.  Retain this information with the respirator, storage compartment, or inspection report until next certification.  You may use tags to document the inspections.

Emergency escape-only equipment.  Must be tested before being carried into the workplace for use.

Repairs  If a respirator does not pass inspection, you must remove the respirator from service and discard, repair, or adjust it.  Tagging out of service respirators is a good means for ensuring that defective respirators are not inadvertently used.

Training  Employees are required to be re-certified on an annual basis.  However, it is recommended that certified employees practice donning, removing and testing their respirator quarterly.

1.  Cylinder
a.  Be sure that the gauge needle and the gauge face
are visible and not bent.                                                                _____________
b.  Inspect the cylinder body for cracks, dents, weakened
areas, or signs of heat-related damage.                                          ____________
c.  Inspect the cylinder valve for signs of damage.  If it is
less than full:2216 psig for steel, or composite I or
Composite II cylinders; 2216-3000 psig for Composite III
cylinders; 4500 psig for 4500 psig cylinders, charge the cylinder
before storage.  Cylinder air must be Grade D (or better)
respirable air.                                                                                 ____________
d.  Check the hydrostatic test date.  Composite cylinders must
be tested every three years.  Steel every five years.                         ____________

2.  Facepiece
a.  Ensure that the facepiece does not have rubber distortion, dirt,
cracks, tears, holes, or tackiness.                                                     ____________
b.  Ensure harness head strap does not have breaks, loss of
elasticity, missing buckles or straps.                                                 ____________
c.  Check the strap serrations for signs of wear.                                    ____________
d.  Ensure that the lens has no cracks or scratches and forms
a tight seal with the facepiece rubber.                                              ____________
e.  Check the exhalation valve, it must be clean and operate easily.       ____________
f.  Check exhalation spring.                                                                  ____________
g.  Inspect the facepiece coupling nut for damaged threads.  Also
check to be sure the gasket is present.                                             ____________

3.  Breathing Tube
a.  Inspect the breathing tube closely for perforations, small
cracks, or signs of wear, especially along the corrugations.             ____________
b.  Check the breathing tube for leaks (see manual)                              ____________

4.  Regulator
a.  Be sure the diaphragm cap is hand-tight.  Check that
the cap is not dented or deformed.  Be sure that the small air
holes around the outer edge of the cap are not blocked.                  ____________
b.  Inspect the pressure gauge (see manual).                                        ____________
5.  Audible Alarm
a.  Check that the alarm rings briefly when the cylinder valve is
opened (usually around 540 psig for a 2216 psig cylinder).             ____________
b.  Check that the bell is on tightly and properly aligned.                      ____________
( see manual)

6.  High Pressure Hose
a.  Look for cuts or severe abrasions and tight fittings.                        ____________

Appendix D to 1910.134 (Non-Mandatory) Information for Employees Using Respirators When Not Required Under the Standard

Respirators are an effective method of protection against designated hazards when properly selected and worn.  Respirator use is encouraged, even when exposures are below the exposure limit, to provide an additional level of comfort and protection for workers.  However, if a respirator is used improperly or not kept clean, the respirator itself can become a hazard to the worker.  Sometimes, workers may wear respirators to avoid exposure to hazards, even if the amount of the hazard does not exceed the limits set by OSHA standards.  If your employer provides respirators for your voluntary use, or if you provide your own respirator, you need to take certain precautions to be sure that the respirator itself does not present a hazard.

You should do the following:

1. Read and heed all instructions provided by the manufacturer on use, maintenance, cleaning and care, and warnings regarding the respirator limitations.
2. Choose respirators certified for use to protect against the contaminant of concern.  NIOSH, the National Institute for Occupational Safety and Health of the U.S. Department of Health and Human Services, certifies respirators.  A label or statement of certification should appear on the respirator packaging.  It will tell you what the respirator is designed for and how much it will protect you.
3. Do not wear your respirator into atmospheres containing contaminants for which your respirator is not designed to protect against.  For example, a respirator designed to filter dust particles will not protect you against gases, vapors, or very small solid particles of fumes or smoke.
4. Keep track of your respirator so that you do not mistakenly use someone else’s respirator.
