1. Personal Protective Equipment (PPE)

2. FACTORS AFFECTING CHEMICAL RESISTANCE 1.Length of exposure time thin materials for one application –disposable

3. FACTORS AFFECTING CHEMICAL RESISTANCE 2. Exposure situation depends on task, sharp or rough objects

4. FACTORS AFFECTING CHEMICAL RESISTANCE 3. Type of chemical Some are corrosive

5. CHEMICAL RESISTANT MATERIALS Materials NOT resistent: cotton leather canvas

6. CHEMICAL RESISTANT MATERIALS rubber or plastic non-woven fabric

7. PROTECTING SKIN most exposure long-sleeved shirt and long-legged pants

8. PROTECTING SKIN Body Coveralls clothes underneath loose to provide air layers

9. PROTECTING SKIN Body Chemical-resistant suit chemical is very hazardous “rain suit” heat stress

10. PROTECTING SKIN Body Chemical-resistant apron mixing and loading

11. PROTECTING SKIN Hand and Foot Gloves hands and forearms whenever handling pesticides if working overhead or below to wear glove in or out of suit

12. PROTECTING SKIN Hand and Foot exposure occurs when gloves removed briefly –adjusting equipment –scratching face always wash gloves before removed

13. Hand and Foot Latex for minor handling and single use PROTECTING SKIN

14. Hand and Foot Footwear Chemical-resistant shoes Not canvas, cloth, and leather –Unless shoe covers

15. PROTECTING SKIN Head and Neck Working overhead wide-brim resistant Greenhouse or trees Hood is for drift from booms

16. PROTECTING EYES goggles, safety glasses, or face shield shield in addition to goggles during mixing

17. PROTECTING RESPIRTORY Respiratory protection - must be NIOSH and MSHA approved enclosed area long period of exposed

18. Air-supplying Respirator air-supplying - air is from independent source –oxygen supply is low –fumigation supplied - limited by the length of hose self-containing - canister of air, 30 - 45 minutes

19. Air-purifying Respirator air-purifying - filter contaminants dusts, mists, gases and vapors

20. Cartridges 1. dust/mist-filtering replace filters when difficult to breathe Air-purifying Respirator

21. Cartridges 2. vapor-removing material –Activated charcoal change when noticing odor or taste replace after 8 hours use Air-purifying Respirator

22. Non-powered air-purifying respirator require operator to draw air through filters exhausting

23. Air-purifying Respirator Powered air-purifying respirator (PAPR) assist operator in drawing air not air-supplying

24. Air-purifying Respirator Face-sealing respirators tight seal –no facial hair full-face styles better than half-face

25. Air-purifying Respirator Face-sealing respirators fit test: testing whether operator can detect substance fit check: –#1, close inlet, breathe in, hold 10 seconds with mask collapsed –#2, cover outlet and exhale until mask inflates

26. Air-purifying Respirator Loose-fitting respirators Pump through filter into helmet or hood –Facial hair allowed

27. MAINTAINING PPE Disposables: not be washed latex gloves shoe covers non-woven coveralls cartridges and filters

28. MAINTAINING PPE Reusable: reused several times rubber and plastic equipment

29. MAINTAINING PPE Reusable gloves holes (ballooning) replace gloves after 5 to 7 days of work –heavy-duty: 10 to 14 days

30. MAINTAINING PPE fabric coveralls: clean after every use throw away if drenched with chemical labeled “DANGER” or “WARNING”

31. MAINTAINING PPE Cleaning equipment detergent and hot water sanitize: 2 minutes in 2 tbs bleach in one gallon of hot water then rinse

32. MAINTAINING PPE Personal equipment wash clothes in hot water separate from regular laundry Dry outdoors –Sunlight
