Respiratory Protection Program
of the Respiratory Protection
Program is to ensure that all employees have adequate respiratory
protection in the workplaces on the Oklahoma State University
campus where engineering controls or work practices are inadequate
or not feasible to reduce the exposure to airborne contaminates.
In all cases,
engineering controls must be considered and implemented to the extent that they are
are found in Appendix C of this document.
shall cover all Oklahoma State University employees on the Stillwater campus who wear
respiratory protection during work activities and those who anticipate wearing respiratory
equipment during an emergency incident. This Respiratory Protection Program
specifically excludes those employees whose primary job function is to abate or work with
asbestos. A separate Asbestos Respiratory Protection Program has been developed to
specifically address asbestos and asbestos employees.
Oklahoma State University shall provide respirators, training, fit testing, and medical evaluations at no cost to the employee.
- The Designated Program Administrator shall be the Environmental Hazards Coordinator (EHC) of the Environmental Health & Safety Department, or his/her designated respresentative.
- The EHC shall have the authority to make decisions and implement changes to the Program as necessary.
- The EHC shall administer/oversee the Program.
- The EHC shall conduct the required evaluations of Program effectiveness.
- The EHC shall ensure that all respirator users are properly trained and fit tested.
- The EHC shall ensure that all employees who wear a negative or positive pressure tight-fitting facepiece shall be fit tested before use in the workplace.
- The EHC shall provide a copy of the Respiratory Protection Program to the OSU Wellness Center (Employee Health Clinic).
- The EHC shall assist departments in identifying, evaluating, and surveying work areas that require respiratory protection.

of Respirators - General Requirements
shall use NIOSH-certified respiratory equipment. A Certified Equipment List can be
found on the NIOSH website.
- OSU shall use respirators and cartridges that are:
approved by the Mine Safety and Health Admininstration (MSHA) and NIOSH as specified in 30
CFR 11, and manufactured after any date; or
- Approved by IOSH as specified in 42 CFR 84. Only those
cartridges manufactured after July 10, 1998, shall be used.
shall select and provide an appropriate respirator for the hazard. OSU shall use the
following as guidance in the selection: 29 CFR Parts 1910.134. 1910.135, 1910.1001,
1926.1101, 1910.1017, 1910.1045, and 1910.1051; the ANSI Standard for Respiratory
Protection Z88.2-1992; and any applicable federal and/or state regulations.
OSU shall identify and evaluate respirator hazards. Where OSU
cannot identify or reasonably estimate the employee exposure, OSU shall consider the
atmosphere to be IDLH. Criteria for this shall be based on the following:
activity or process the employee will be engaged in,
type of respiratory hazard. This would include the physical, chemical, and
physiological properties of the respiratory hazard or air contaminant;
concentration of the air-borne contaminate that would be encountered in the work area;
time spent wearing respiratory equipment;
published TLV, PEL, EDLH, C (ceiling), STEL or any other available exposure limit for the
existence of a specific standard for a particular process or chemical that may require
specific respiratory protection equipment;
actual and potential oxygen content in the work area's ambient air, i.e., the
determination of an oxygen-deficient atmosphere;
capabilities and limitations of respiratory protection equipment used;
ability of the cartridges to protect the wearer from the air-borne contaminants; and
The respirator-assigned protection factors.
OSU shall select respirators from a sufficient number of respirator
models and sizes so that the respirator is acceptable to and correctly fits the user.
If OSU determines that the atmosphere is an IDLH atmosphere, then OSU shall provide one of the following respirators for the employee:
demand SCBA minimum 30 min; or
with auxiliary self-contained air supply; or
Respirator provided only for escape from IDLH atmosphere shall be
NIOSH-certified for escape from that atmosphere.
Oxygen deficient atmospheres shall be considered IDLH, unless
demonstrated that the oxygen concentration is 16.0-19.5% by volume. (Elevation for

workplace. OSU will discontinue an employee's medical evaluations when the employee
is no longer required to use a respirator.

The PLHCP shall provide a written recommendation regarding the employee's ability to use a respirator. In this recommendation, the PLHCP shall provide the following information:
Any limitations on respirator use related to the medical condition of the employee, or related to the workplace conditions in which the respirator will be used, including whether or not the employee is medically able to use the respirator.
The need, if any, for follow-up medical evaluations.
A statement that the LHCP has provided the employee with a copy of the PLHCP's written recommendation.
If the respirator is a negative-pressure respirator and the PLHCP finds a medical condition that may place the emloyee's health at increased risk if the respirator is used, OSU shall provide a PAPR if the PLHCP's medical evaluation finds that the employee can use such a respirator. If a subsequent medical evaluation finds that the employee is medically able to use a negative-pressure respirator, then OSU is no longer required to provide a PAPR.

If available, the respirator wearer shall use the
End-of-Service-Life Indicator (ESLI) to determine when to change out air-purifying
elements. If no ESLI is available for the selected air-purifying elements, then EHS
shall be consulted to determine a change-out schedule to ensure that the air-purifying
elements are changed out before the end of their useful service life.
The following factors may be utilized to estimate ESLI:
relative humidity of the work area. Humidity above 85% can reduce an air-purifying
element's estimated service life by approximately 50%.

factor of ten (10), the service life of an air-purifying element can be increased by a
factor of five (5).

work stresses, the shorter the air-purifying element's serivce life.

If the respirator wearer experiences any odor, taste, or irritation,
or experiences excessive breathing resistance, the wearer shall:
leave the contaminated area,

the change-out schedule to shorter times, and
Contact EHS for possible changes to the existing change-out
The respirator wearer shall change-out and discard any air-purifying
elements that have reached their ESLI, failed during use, become damaged or wet, or become
difficult to breathe through.
If conditions are causing the air-purifying elements to fail before
their ESLI, then EHS shall be contacted to determine if the job function requires the use
of a supplied-air respirator.
For those cartridges that do not have an
