respiratory terminology1
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.
respiratory terminology2
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.
respiratory terminology3
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.

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

Tight fitting facepiece.

respiratory protection program1
Respiratory Protection Program

Sub paragraph C of 29 CFR 1910.134

requires the employer to develop and

implement a written respiratory protection

program with required worksite-specific

procedures and elements for required respirator


* In any workplace where respirators are necessary

* Administered by a suitable trained program


* Voluntary use

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 ?



Does the employer permit

Voluntary use of respirators ?

Must establish & implement a

written respirator program with

worksite-specific procedures




Does the only use of respirators involve the voluntary use

of filtering facepieces ?



* 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

written respiratory protection program
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
written respiratory protection program1
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
written respiratory protection program2
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

What are the nine components of a Written Respiratory Protection Program?

(c)(1)(i) thru (c)(1)(ix)

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 check
qualitative qlft1

Isoamyl Acetate (banana oil)


Sodium Saccaharin

Irritant Smoke

qualitative qlft2

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)

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….
  • 1/ff1+1/ff2+1/ff3+………1/ff8
quantitative qnft2

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

fit test record
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

fit test record1
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

Which type of Fit Test requires a threshold screening?


medical evaluation1
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
medical evaluation procedures
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.
