Respiratory Terminology

S-10

Respiratory Terminology

• Tight fitting facepiece – a respirator inlet covering that forms a complete seal with the face

• Positive pressure respirator- a respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator.

• Negative pressure respirator – a respirator in which the pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator.

S-11

Respiratory Terminology

• Atmosphere-supplying respirator – a respirator that supplies the user with breathing air, such as: SCBA, Rebreather or SAR

• Pressure demand respirator – a positive pressure ASR that admits breathing air to the facepiece when the positive pressure is reduced inside the facepiece by inhalation.

• Air-purifying respirator – a respirator with an air-purifying filter, cartridge, or canister that removes air contaminants by passing ambient air through the element.

• Powered air-purifying – an air-purifying respirator that uses a blower to force the ambient air through the element to the inlet covering.

S-12

Respiratory Terminology

• Fit test – the use of a protocol to quantitatively or qualitatively evaluate the fit of a respirator on an individual.

• Qualitative fit test (QLFT) – a pass/fail test to assess the adequacy of respirator fit that relies on the individual’s response to the test agent.

• Quantitative fit test (QNFT) – an assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator.

S-13

A facepiece that forms a complete seal with the users face is referred to as what type of facepiece?

Tight fitting facepiece.

Respiratory Protection Program

S-15

Respiratory Protection Program

Sub paragraph C of 29 CFR 1910.134 requires the employer to develop and implement a written respiratory protectionprogram with required worksite-specificprocedures and elements for required respiratoruse.

* In any workplace where respirators are necessary* Administered by a suitable trained program administrator* Voluntary use

S-16

Respiratory-Use Requirements Flow Chart 29 CFR 1910.134 (c) Are respirators:

* necessary to protect the health of the employee; or

* required by the employer ?Yes No

Must establish & implement a written respirator program withworksite-specific procedures

Does the employer permitVoluntary use of respirators ?

Yes No

STOP

Does the only use of respirators involve the voluntary useof filtering facepieces ?

Yes No

* Employer determines respirator doesn’t create a hazard* Provide info in Appendix D* No respirator program required

* Employer determines respirator doesn’t create a hazard* Provide info in Appendix D* Must establish & implement those elements of a written respirator program necessary to ensure that employee is medically able to use that respirator

S-17

Written Respiratory Protection Program

• (c)(1)(i) Procedures for selecting respirators in use in workplace

* Evaluate Hazards* NIOSH Certified Respirator

• (c)(1)(ii) Medical evaluations of employees required to use respirators

• (c)(1)(iii) Fit test procedures for tight fitting respirators

S-18

Written Respiratory Protection Program

• (c)(1)(iv) Procedures for proper use of respirators in routine and reasonably foreseeable emergency situations

• (c)(1)(v) Procedures and schedules for cleaning, disinfecting, storing, inspecting, repairing, discarding and otherwise maintaining respirators

• (c)(1)(vi) Procedures to ensure adequate air quality, quantity, and flow of breathing air for ASR

S-19

Written Respiratory Protection Program

• (c)(1)(vii) Training of employees in the respiratory hazards to which they are potentially exposed during routine and emergency situations

•(c)(1)(viii) Training of employees in the proper use of respirators, including putting on and removing them, any limitations on their use and their maintenance

•(c)(1)(ix) Procedures for regularly evaluating the effectiveness of the program

Respirator Fit Testing

S-22

Qualitative(QLFT)• Isoamyl Acetate Protocol

* Requires an odor threshold screening

• Saccharin Solution Aerosol Protocol * Requires a taste threshold

screening

•Bitrex Solution Aerosol Protocol * Requires a taste threshold

screening

• Irritant Smoke Protocol * Requires a sensitivity screening

Qualitative(QLFT)

Isoamyl Acetate (banana oil)

Bitrex

Sodium Saccaharin

Irritant Smoke

Qualitative(QLFT)

Advantages Disadvantages

* Inexpensive up-front cost * Imprecise

* Low maintenance * Easy to do wrong (tedious)

* Limited to fit factor of 100

* Subject to deception

* No documentation of results

* People dislike wearing the hood

* Slow (because of threshold test)

S-25

Quantitative(QNFT)• Generated Aerosol Quantitative Fit Testing Protocol

• Using a non-hazardous aerosol such as:

* corn oil * polyethylene glycol * sodium chloride * di-2-ethyl hexyl sebacate

Overall Fit factor = number of exercises….

Quantitative(QNFT)

S-28

Quantitative(QNFT) Advantages Disadvantages

* No fit factor limit * More expensive up front cost

* Precise * Requires probed respirator or

* Faster a Sampling adapter

* Annual factory recalibration

* No chance of deception

* recommended

* Easy to do right

* Useful for employee respirator training

* Hard copy documentation of results

S-29

Fit Test Record

• The employer shall establish a record of the qualitative and quantitative fit test administered to an employee.

• The record shall include:* employee name or ID* type of fit test* specific make, model, style of

respirator* date of test* pass/fail for QLFT* fit factor for QNFT

S-30

Fit Test Record•The fit test record will be maintained until the next administered test:

* Annual test

* Changes in respiratory protection

* Changes in the employee

S-31

Check on Learning

Which type of Fit Test requires a threshold screening?

Qualitative(QLFT)

S-32

Medical Evaluation

S-33

Medical Evaluation

• The employer shall provide a medical evaluation to determine the employee’s ability to use a respirator.

• Prior to fit testing and use

• May be discontinued when employee is no longer required to use a respirator

S-34

Medical Evaluation Procedures

• The employer shall identify a physician or other licensed health care professional (PLHCP)

• The medical evaluation shall obtain the information requested by the questionnaire in section 1 and 2, part A of appendix C.

• The employer shall ensure that a follow up medical evaluation is provided for an employee that give a positive response to questions 1- 8, or gives indication that a follow up is needed.

S-35

Medical Evaluation Procedures

The medical questionnaire and examination * administered confidentially

* during the employee’s normal working hours

* or at a time and place convenient to the employee.

S-36

Check on Learning

Who is authorized to administer medical screening?

The employer shall identify a physician or other licensed health care professional (PLHCP)
