1/05 School Safety Training Respirators A Program Overview WISHA WAC WAC OSHA 29 CFR

2 NOTICE  This presentation is provided to all Educational Service District 101 (ESD 101) schools at no cost.  This presentation contains copyrighted materials purchased by ESD 101 for the exclusive use of training school personnel within ESD 101.  This presentation may not be reproduced except to print “handouts” or “notes pages” for use during training within ESD 101 school districts.  If the school district does not have Microsoft’s PowerPoint software available, a PowerPoint viewer can be downloaded from the internet at no cost.  Questions may be directed to the ESD 101 Risk Manager.

3 Why respiratory protection is necessary  Air contaminants/hazardous atmospheres come from a variety of sources Dusts Aerosol mists Metal fumes

4 Why respiratory protection is necessary  Air contaminants/hazardous atmospheres come from a variety of sources Evaporated vapors Released gases Oxygen-deficient atmospheres

5 Why respiratory protection is necessary  Many operations generate air contaminants Filling bins with flour Degreasing metal parts Spraying operations Welding

6 Why respiratory protection is necessary  Find out how much contaminant is in the air  Test the air to find out what the exposures are

7 Why respiratory protection is necessary  If results show an overexposure, take steps to control the hazard Engineering controls Administrative controls PPE

8 Respirator types  Atmosphere-supplying Supplied air Self-contained breathing apparatus (SCBA) Demand Positive pressure Escape-only

9 Respirator types  Air-purifying Filter Canister or cartridge

10 Respirator types  Air-purifying Negative pressure Powered air-purifying

11 Fit, usage, and maintenance  Employees must pass a fit test Quantitative fit (Irritant smell) Qualitative fit (porta-count)  Use the respirator as it was designed

12 Fit, usage, and maintenance  Follow operating instructions  If respirators are used to enter an IDLH atmosphere: one trained, rescue-equipped employee must remain outside an attendant must maintain communication contact (ESD 101 School Program NEVER allows employees to enter into IDLH atmospheres)

13 Fit, usage, and maintenance  During interior structural firefighting: at least 2 employees with SCBA must enter together and stay in contact with each other at least two people trained and equipped for rescue must remain outside (ESD 101 School Program NEVER allows employees to engage in firefighting activities)

14 Fit, usage, and maintenance  A dirty, inoperative respirator will not protect you

15 Inspection, donning, doffing respirators  Inspect respirators before each use and during cleaning  Inspect SCBAs monthly and keep cylinders fully charged  (ESD 101 School Program NEVER allows employees to use SCBA respirators)

16 Inspection, donning, doffing respirators  Emergency-use respirators: inspect monthly tags must show inspection results  Follow manufacturer’s instructions for donning/doffing equipment  (ESD 101 School Program NEVER allows employees to use emergency-use respirators)

17 Inspection, donning, doffing respirators  Perform seal checks after donning respirator Positive pressure test Negative pressure test Review Appendix B-1 (WAC )  Never enter a work area without a good respirator seal

18 Cleaning, maintenance, and storage  Respirators must be cleaned to remove contaminants/prevent irritation  Shared respirators must be cleaned before each use  (School administrators and/or managers assign individual-use respirators to employees who are authorized for respirator use)

19 Cleaning, maintenance, and storage  Emergency-use respirators must be cleaned after each use  Review Appendix B-2 (WAC ) for cleaning/disinfecting instructions  Only use manufacturer’s replacement parts

20 Cleaning, maintenance, and storage  Damage  Contamination  Dust  Sunlight  Temperature extremes  Excessive moisture  Chemicals  Deformation of the facepiece Storage helps prevent respirators from:

21 Responding to Emergencies  If the respirator malfunctions, immediately leave the work area  Activate auxiliary self-contained air supply  (ESD 101 School Program does not use auxiliary air supply since no self-contained respirators are utilized in the program)

22 Responding to Emergencies  If a sudden hazardous release occurs, don emergency escape-only respirators as you exit the area  (ESD 101 School Program does not use emergency escape-only respirators since no self-contained respirators are utilized in the program)

23 Responding to Emergencies  Some employees must be trained and authorized to respond to emergency situations (Not in ESD 101 School Program) Confined space rescue Release of hazardous chemicals Interior structure firefighting (SST Program NEVER allows employees to enter into IDLH atmospheres)

24 Medical signs and symptoms  Know how to recognize and report medical signs and symptoms that may limit or prevent the effective use of respirators  Shortness of breath  Dizziness

25 Medical signs and symptoms  Coughing  Wheezing  Chest pain

26 Medical signs and symptoms  Chest injuries  Lung diseases  Cardiovascular conditions

27 Medical signs and symptoms  Heart conditions  Review Appendix C: OSHA Respirator Medical Evaluation Questionnaire (Federal)  WAC Appendix C: WISHA Respirator Medical Evaluation Questionnaire (WA State)

28 Regulations  Review the main paragraphs (“a” through “o”) of 29 CFR (Federal)  Review WAC (WA State)  Review the program “Respirators- Regulatory Requirements” in this training series.
