1 Respiratory Protection Instructional Goal To gain a better understanding of the purpose of respirators, their limitations, and the importance of an effective respirator program.

2 Respiratory Protection Program zWritten SOPs for selection and use zSelection based on hazard exposure zInstruction and training zInspection, cleaning and disinfection zStorage

3 Respiratory Protection Program zSurveillance of conditions and exposure zMedical Surveillance - physician's written opinion zFit testing - Qualitative and Quantitative zProgram review and evaluation

4 Respiratory Protection Program Selection of respiratory protection equipment is of primary importance

5 Respiratory Protection Equipment Positive pressure SAR Atmosphere - Supplying Respirators SCBA Pressure demand Continuous flow

Respiratory Protection Equipment APR Negative pressureContinuous Flow PAPR Half Face Full Face

7 Personal Protective Equipment APFRespirator 5 Filtering facepiece (single use dust) 10 Half-facepiece Respirator with Vapor Cartridge or Filter 50 Full-facepiece Respirator with Vapor Cartridge or Filter 1,000 Full-facepiece Supplied Air Respirator operated in Pressure - demand mode. 1,000 toFull-facepiece Self-contained 10,000breathing apparatus operated in Pressure demand mode

8 Personal Protective Equipment zA respirator should ensure that the worker will not be exposed to the chemicals present above the applicable limits yAmerican Conference of Governmental Industrial Hygienists Threshold Limit Values (TLVs) yOSHA's Permissible Exposure Limits (PELs) yNIOSH Recommended Exposure Limits (RELs)

9 Personal Protective Equipment za worker has a high breathing rate zthe ambient temperature is high or low zthe worker has a poor facepiece to face seal Any respirator can be compromised if :

10 Air - Purifying Respirators zselectively remove specific airborne contaminants zNOT for IDLH atmospheres zuse only in atmosphere with sufficient oxygen (19.5%) zusually are a negative pressure device

11 Air - Purifying Respirators zParticulate filters zCartridges and canisters, with specific gas and vapor sorbents zCombination devices

12 Air - Purifying Respirators RESPIRATOR CARTRIDGES/FILTERS COLOR APPROVED FOR Black Organic Vapors YellowOrganic Vapors and Acid Gases Yellow Organic Vapors and Acid Gases White White Acid Gases GreenAmmonia and Methylamine Green Ammonia and Methylamine PurpleHEPA, Dusts, Fumes and Mists Purple HEPA, Dusts, Fumes and Mists Orangestripefor Dusts, Fumes and Mists in combination with vapor or gas Orange stripe for Dusts, Fumes and Mists in combination with vapor or gas

13 Air - Purifying Respirators Warning properties are essential to safe use of air-purifying respirators since they allow detection of contaminant breakthrough should it occur.

14 Air - Purifying Respirators Change your cartridges according to your employer’s change schedule Do Not Wait for Contaminant Breakthrough to Replace Your Cartridges If You Experience Contaminant Breakthrough, You Experience Exposure !

15 Self-Contained Breathing Apparatus Employees engaged in emergency response to spills and releases and exposed to hazardous substances presenting an inhalation hazard or potential inhalation hazard shall wear positive pressure self-contained breathing apparatus (SCBA).

16 Self-Contained Breathing Apparatus zEscape Only SCBAs zEntry and Escape SCBAs yopen circuit - exhale to air yclosed circuit - exhale to scrubber

17 Self-Contained Breathing Apparatus zIs atmosphere IDLH or likely to be? zIs duration of air supply sufficient? zWill bulk / weight of SCBA interfere with task? zWill temperature affect either SCBA or worker? Decision Map

18 Supplies Air Respirators - SARs zSupply AIR, not oxygen zpositive pressure & negative pressure types zless bulky zlonger work period zlimitations

19 Supplied Air Respirators- SARs zContaminant to air source? zHose length and mobility? zHose damage? zIs atmosphere IDLH or likely to be? zInterference with air line? Decision Map

20 Respirator Fit zInterference with fit zRespirator fit testing yquantitative fit testing yqualitative fit testing
