Title: RESPIRATORY PROTECTION


1
RESPIRATORY PROTECTION
  • From Hazardous Atmospheres
  • 29 CFR 1910.134

2
EFFECTIVE DATES
  • January 8, 1998 - OSHA Publishes Standard
  • April 8, 1998 - Effective Date
  • September 8, 1998 - Determination Date That
    Respirators Are Required And Who Will Wear Them
  • October 5, 1998 - Total Compliance With All
    Provisions Of Standard

3
REVISIONS TO STANDARDS
  • Respirators Deleted From All Other Substance
    Specific Standards
  • Previous Respirator Standard Renumbered As .139
    And Designated Temporarily As M. tuberculosis
    Standard
  • All Respirator Issues Are Now In 1910.134

4
RESPIRATOR PROGRAM
  • Requires A Written Program With Worksite-Specific
    Procedures When Respirators Are Needed
  • Must Keep Updated As Needed
  • A Program Administrator Is Required For The
    Entire College
  • College Must Provide Respirators, Training, And
    Medical Evaluations At No Cost To Employees

5
RESPIRATOR PROGRAM ELEMENTS
  • Selection
  • Medical Evaluation
  • Respirator Use
  • Maintenance And Care
  • Fit Testing
  • Breathing Air Quality And Use
  • Training
  • Program Evaluation

6
WHERE RESPIRATORS ARE USED BUT NOT REQUIRED
  • If Respirators Will Not Create A Hazard And If
    Requested, College May Furnish Respirators
  • If Approved, Employees May Wear Their Own, But
    Must Follow Program Requirements
  • Voluntary Use Of Filtering Facepieces (Face
    Masks) Does Not Have To Be Included In The
    Written Materials

7
PERMISSIBLE PRACTICES
  • Engineering Controls (Enclosures, Confinement Of
    Operations, Ventilation, Use Of Less Toxic
    Materials) Are Primary Means To Control Hazards
  • When Effective Engineering Controls Are Not
    Available, Respirators Will Be Used
  • Respirators Will Be Applicable To And Suitable
    For The Purpose Intended
  • Employer Will Be Responsible For Program

8
SELECTION OF RESPIRATORS
  • College Will Select And Provide An Appropriate
    Respirator Based On The Respiratory Hazards To
    Which The Worker Is Exposed, Workplace Factors,
    And User Factors That Affect Respirator
    Performance And Reliability
  • Respirators Will Be Selected From A Sufficient
    Number Of Models And Sizes To Ensure Correct Fit
    And Comfort

9
RESRIRATOR PROTECTION TRAINING
  • Employers (Managers And Supervisors) Must Provide
    Appropriate And Effective Training To Employees
    Who Are Required To Use Respirators

10
RESRIRATOR PROTECTION TRAINING
  • Employees That Use Respirators Must Be Trained
    And Demonstrate Skill Or Knowledge Of At Least
  • Why It Is Necessary And How Improper Use And Care
    Can Compromise Its Effectiveness
  • Its Limitations And Capabilities
  • How To Put On, Remove, Use, And Inspect
  • How To Maintain And Store
  • General Requirements Of This Standard

11
RESRIRATOR PROTECTION TRAINING
  • Training Must Be Provided Prior To Use
  • Retraining Required Annually, And When
  • Prior Training Becomes Obsolete
  • Employees Skill Or Knowledge Is Inadequate
  • Other Situation Arises In Which Retraining
    Appears Necessary

12
EMPLOYEE EXPOSURE
  • Exposure To A Concentration Of An Airborne
    Contaminant That Would Occur If The Employee Were
    Not Using Respiratory Protection

13
RESPIRATORY INLET COVERING
  • That Portion Of A Respirator That Forms The
    Protective Barrier Between The Users Respiratory
    Tract And An Air-Purifying Device Or Breathing
    Air Source
  • May Be A Facepiece, Helmet, Hood, Suit, Or
    Mouthpiece Respirator With A Nose Clamp
  • May Be Tight Fitting Or Loose Fitting

14
HAZARDOUS ATMOSPHERES
  • Oxygen Deficient
  • Toxic Contaminated
  • Environmental Pollution
  • Combination
  • Immediately Dangerous To Life Or Health (IDLH)
  • Note All Can Be Either Acidic Or Alkaline

15
OXYGEN DEFICIENT
  • An Atmosphere With An Oxygen Content Below 19.5
    By Volume
  • Spaces Where Oxygen May Be Depleted By Use
    (Confined Spaces, Boilers, Tanks, Etc.)
  • Space Where Decomposition Of Organic Material Is
    Going On (Sewers, Silos, Basements, Etc.)

16
TOXIC CONTAMINATED
  • Particles
  • Gases
  • Fumes
  • Vapors
  • Mists

17
ENVIRONMENTAL POLLUTION
  • Dust
  • Spray
  • Fumes
  • Vapors
  • Smoke
  • Harmful Gases

18
TWO BASIC TYPES OF RESPIRATORS
  • Air Purifying - Removes Contaminates Before
    Reaching Breathing Zone
  • Atmosphere Supplying - Provides Fresh Air From An
    External Source

19
AIR PURIFYING
  • May Be Particulate Removing
  • Vapor And Gas Removing
  • A Combination Of The Two
  • Uses A Replaceable Cartridge Or Canister

20
AIR PURIFYINGUSE LIMITATIONS
  • Just Enough Oxygen To Sustain Breathing
  • Contaminate Is Known And Cannot Exceed Facepiece
    Limitations
  • Contaminates Are Not IDLH
  • Always Treat Oxygen-Deficient Air As IDLH

21
ATMOSPHERE SUPPLYING
  • Type 1 - Airline Respirator. Air Is Pumped To
    The User From Outside
  • Type 2 - Self Contained Breathing Apparatus
    (SCBA)

22
AIRLINE RESPIRATOR

  • Positive Pressure Provides Protection For Both
    Oxygen Deficient And IDLH

24
RESPIRATOR SELECTION
  • Must Fit The Wearer And Be Comfortable
  • Must Be The Type Which Best Abates The Hazards To
    Be Faced
  • Atmosphere Hazard Evaluation Determines Which One
    To Wear
  • Never Substitute Or Chance Another One Will
    Provide Adequate Protection

25

    Employees

28
FIT TESTING
  • Before An Employee Uses Any Respirator With A
    Negative Or Positive Pressure Tight-Fitting
    Facepiece, The Employee Must Be Fit Tested With
    The Same Make, Model, Style, And Size Of
    Respirator That Will Be Used
  • Must Be Administered Using An OSHA Accepted
    Protocol Such As That Contained In Appendix A

29
FIT TESTING
  • Respirators Rely On Face-To-Mask Seal
  • Fit Testing Determines Which Device Will Best Fit
    And Seal

  • More Often If Facial Features Change Or
  • A Different Respirator Is To Be Used
  • Users Of Tight Fitting Respirators Must Perform A
    Seal Test Each Time They Are Used

31
TYPES OF FIT TESTING
  • Qualitative (QLFT) - Challenge Agent, Vapor, Or
    Aerosol Released
  • Fit Is Inadequate If A Presence Of The Agent Is
    Detected (Irritation, Taste, or Odor)
  • Quantitative (QNFT) - Measures Actual Level Of
    Agent Both Inside And Outside The Respirator

32
FIT TESTING
  • QLFT May Only Be Used To Fit Test Negative
    Pressure Air Purifying Respirators That Achieve A
    Fit Factor Of 100 Or Less
  • A Fit Factor Of At Least 100 For Tight- Fitting
    Half Facepieces, Or 500 For Tight-Fitting Full
    Facepieces From A QNFT Will Be Acceptable

33
FIT FACTOR
