1.0 PURPOSE

The primary objective of this program is to prevent respiratory injury due to atmospheric contamination. As far as feasible this shall be accomplished by accepted engineering controls (i.e., enclosure, confinement, ventilation, and substitution). When effective engineering controls are not feasible, or while they are being instituted, occupational  respiratory injuries and illnesses caused by breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes sprays or vapors, will be controlled by the use of appropriate respiratory protection equipment. This program will outline the training, inspection, and utilization of respirators.

4.0 Medical Evaluation

4.1 (Alternate) BYU-Idaho personnel will not be assigned to tasks requiring use of respirators unless it has been determined that they are physically able to perform the work and use the equipment. A BYU-Idaho physician shall determine what health and physical conditions are pertinent. (This is the OSHA 29 CFR 1910.134)

4.1.1 A physician shall determine if employees are indeed physically able to wear a respirator as part of their work assignment. (This is from ANSI Z.88.6 a good idea but not mandated)

4.2 Frequency. This medical examination should be conducted every five years up to age 35, every 2 years up to age 45, and annually thereafter. (This goes with previous one)

4.3 Pulmonary Function Test. Spirometry will be used to screen individuals that use respirators incidentally to their job performance. If the FVC (forced vital capacity) is less than 80 percent or the FEV1 (forced expiratory volume - 1 second) is less than 70 percent, restriction from respirator use will be considered.

4.4 Medical History. A medical history questionnaire will be utilized to identify the following:

4.4.1 Previously diagnosed diseases, especially cardiovascular or respiratory diseases

4.4.2 Psychological conditions that might effect respirator use (claustrophobia)

4.4.3 Problems associated with breathing during normal work activities

4.4.4 Past problems with respirator use

4.4.5 Past and current usage of medication

4.4.6 Known physical deformities or abnormalities which may interfere with respirator use

4.4.7 Previous occupations

4.4.8 Susceptibility to tachycardia (rapid beating of the heart) produced by breathing heated air.

4.5 A determination will be made by the examining physician into which of three possible categories the respirator user falls:

Class 1 No restrictions

Class 2 Limited Restrictions (Specifically identified by the physician)

Class 3 No respirator use allowed under any circumstances (This goes with medical exam )

4.6 Corrective Lenses. Because of the potential of serious fitting problems by individuals wearing corrective lenses, ONLY the BYU-Idaho Safety Department can authorize respirator use to these individuals.

4.6.1 The wearing of contact lenses in contaminated atmospheres is not allowed.

5.0 Monitoring.

5.1 A representative of the BYU-Idaho Safety Office or other competent person shall perform all required air monitoring.

5.2 The competent person shall make a reasonable determination as to which substances to monitor and how frequently to monitor

5.3 Air sampling data are important in the selection of the proper respirator and should include:

5.3.1 Identification of the contaminant

5.3.2 Nature of the hazard

5.3.3 Concentration in the breathing zone.

6.0 Selection of Respirators.

6.1 The selection of the appropriate respirator will be made only after considering a wide assortment of contaminant variables. Among them are the following:

6.1.1 The physical state of the contaminant -- dust, mist, vapor, fume, or gas

6.1.2 Its physical properties such as molecular weight, water solubility and vapor pressure

6.1.3 Physiologic effects on the body, such as eye irritation, skin adsorption or dulling of the sense of smell.

6.1.4 Measured concentrations compared to permissible exposure level

6.1.5 Warning properties and odor thresholds.

6.2 Job and individual requirements shall be considered in the selection of respirators. These include:

6.2.1 Length of time respirator will be worn

6.2.2 The activity of the wearer

6.2.3 Additional requirements of eye protection

6.2.4 Communication

6.2.5 Temperature

6.2.6 Personnel acceptance and face fit

6.3 Unusual factors should be anticipated in selecting respirators. Some examples include:

6.3.1 Adsorption through or irritation of the skin

6.3.2 Radiation of the skin and whole body

6.4 Air Purifying Respirators

6.4.1 Air purifying respirators will not be worn in atmospheres containing less than 19.5% oxygen by volume.

6.4.2 Air purifying respirators will not be used where the contaminants are unknown.

6.4.3 Air purifying respirators will not be used where high or moderate levels of exposure are expected.

6.4.4 Air purifying respirators will not be used when any of the following contaminants are present:

carbon monoxide
hydrogen cyanide
hydrogen fluoride
hydrogen sulfide
methylene chloride
nitrous oxides
ozone
Aisocyanates"
vinyl chloride
(This list is not all inclusive)

6.4.5 Only NIOSH/MSHA -- certified respirators will be used.

6.4.6 The selection of respirators will be made by the BYU-Idaho Safety department or its' qualified designee.

Table of Contents

7.0 Training.

7.1 Minimum training shall include the following:

7.1.1 Instruction in the nature of the hazard and an appraisal of what may happen if the respirator is not worn.

7.1.2 A discussion of the respirators capabilities and limitations.

7.1.3 Every respirator wearer shall receive fitting instructions including demonstrations and practice in how the respirator should be worn, how to adjust it, and how to determine if it fits properly. (Respirators shall not be worn when conditions such as facial hair, temple pieces on glasses, or absence of one or both dentures, prevent a good face seal.)

7.1.4 Training shall provide individuals an opportunity to handle the respirator, have it fitted properly, test its facepiece-to-face seal, wear it in normal air for a long familiarity period, and, to wear it in a test atmosphere.

7.2 Fit Testing.

7.2.1 A qualitative fit test will be conducted initially and as part of the regular medical evaluation.

7.2.2 A fit check will be conducted by employees each time they don a respirator. This check can be performed in either of 2 ways:

7.2.2.1 Positive Pressure: the wearer covers the exhalation valve and breathes out. If a slight positive pressure is felt inside the facepiece, the respirator is adjusted properly.

7.2.2.2 Negative Pressure: The wearer covers both cartridges with his hands and inhales. The test is deemed acceptable if the facepiece collapses slightly, and stays collapsed while the wearer holds his breath.
