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

  14. PROTECTING SKIN 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. Air-purifying Respirator Cartridges 1. dust/mist-filtering • replace filters when difficult to breathe

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

  22. Air-purifying Respirator 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
