  1. INDOOR AIR QUALITY A CUSTODIAL APPROACH Presented By: KENWAY DISTRIBUTORS

  2. Causes of IAQ Problems • Reduced Ventilation • Dampness • Inadequate Maintenance

  3. Why is IAQ a Problem? Since the energy crisis of the 70’s, buildings are built tighter ... have less ventilation... and common pollutants are trapped inside.

  4. Why is IAQ a Problem? EPA STUDIES SHOW THAT INDOOR POLLUTANTS ARE 10 –100 TIMES GREATER THAN OUTDOOR

  5. Why is IAQ a Problem? AMERICANS SPEND 80% - 90% OF THEIR TIME INDOORS COST OF EMPLOYEE ABSENTEEISM IS ESTIMATED BETWEEN $6 - $9 BILLION EACH YEAR

  6. Indoor Air In Schools “ Aging schools are our biggest problem now.” “1 in 10 schools have health problems reported by students and employees.”

  7. GAO Report A survey of 10,000 U.S. schools found ... IAQ to be a problem in 1 in 5 schools. Inadequate ventilation in 35% of schools. Persistent leaks in 26% of schools.

  8. “Long ago the schools cut back on maintenance; now there are health problems caused by leaking roofs ... water seepage ... and mold.”

  9. HEALTH EFFECTS OF IAQ • SICK BUILDING SYNDROME HEADACHES, FATIGUE, NAUSEA ITCHING / BURNING EYES, SKIN IRRITATION, NASAL CONGESTION AND IRRITATED THROAT • BUILDING RELATED ILLNESSES RESPIRATORY ALLERGIES LEGIONNAIRES DISEASE

  10. NIOSH NATIONAL INSTITUTE OF OCCUPATIONAL SAFETY & HEALTH SURVEYED 480 BUILDINGS AND SITED FIVE MAIN AREAS OF CONCERN

  11. NIOSH SURVEY • INADEQUATE VENTILATION • INDOOR CONTAMINATES • OUTSIDE ACTIVITIES • INDOOR MOISTURE • BUILDING MATERIALS

  12. INADEQUATE VENTILATIONNew Construction:Reduced Air Exchange...80% of HVAC Systemsare improperly installed and maintained

  13. IAQ INDOOR CONTAMINATES

  14. Common PollutantsBecome Trapped Indoors • Odors (VOCs) • Dust • Allergens (biological)

  15. Chemical Odors (VOCs) • Paint, varnish, solvents • Glues, adhesives • Cleaning chemicals • Particle board • Tobacco smoke • Auto exhaust • Gasoline fumes

  16. How to Reduce VOCs REMOVE SOURCE Mix Chemicals Properly – Use Proportioning Equipment Use - User Friendly Chemicals (Green) Do not mix several Chemicals together Always Clean Equipment Do not leave Containers open Always Clean and dry mops

  17. Precautions During Special Cleaning Procedures STRIPPING HARD FLOORS • Make everyone aware special procedures are being performed • Make sure there is proper ventilation • Dilute strippers properly • Only dilute the amount of stripper that will be used

  18. Precautions During Special Cleaning Procedures Shampooing and Wet Extracting • Make everyone aware special procedures are being performed • Make sure there is proper ventilation • Dilute products properly • Let carpet dry completely • Vacuuming carpet when dry is critical to IAQ

  19. IAQ IN RESTROOMS

  20. Odor SOURCES In Restrooms • Bacteria • Human & Natural odors • Urine • Drains • Maintenance odors Stale air, caulking, tile replacement and replacing grout

  21. Drain Maintenance Problems • Clogs and blockages • Slow Drains • Odor

  22. How to Reduce VOCs IF WE CAN’T REMOVE THE SOURCE WE NEED TO MODIFY THE SOURCE Increase Ventilation Clean Vents for good air flow

  23. DUST

  24. What is Dust? Anything small enough to float in air. • ash, soot, dirt • cotton, paper, fibers • asbestos, fiberglass • paint, metal, mineral • plaster, chalk • dander, pollen, spores

  25. Size of Airborne Dust • Very small (1 - 100 microns) • 1/100,000 to 1/10,000 inch • Cannot be seen by • “naked eye”

  26. Over 85% of Building Dust WALKS in the door

  27. To Reduce Dust • Walk off Mats • Filters, filters, filters... • Treated Dust Cloths • Dust Mopping • Always dust mop after buffing • Dust air vents • Effective Vacuuming with good vacuum

  28. Top Indoor Allergens • Dust Mites & Cockroaches • Mold - airborne spores • Cats & Dogs - airborne dander

  29. YOU CAN’T SEEALLERGENS ... you can only see the reactions to them.

  30. Allergic Reactions • sneezing • runny nose • congestion • headache • fatigue • nausea • sore throat • asthma attack

  31. HOUSE DUST MITES FOUND IN mattresses, pillows, upholstered chairs and carpet. .

  32. TO REDUCE DUST MITES • Effective Vacuuming • Use Tools to Vacuum Upholstery • Change Vac Bag when needed • Keep Vacuums Clean

  33. COCKROACHES • Found in food areas, grease traps … and in general distribution around food service areas.

  34. TO REDUCE COCKROACHES Remove Protein and Food Source Clean, Clean, Clean Have Infested area Treated

  35. MOLD • The most common indoor allergen • Grows on any damp surface • Growth begins in only 24 hours • Optimal conditions, 77 to 88 degrees F, 70 to 93% humidity

  36. Like all plants and animals, mold needs moisture.

  37. Indoor Mold Spores are Normal • They come from the outside air. • Indoor levels should be less than outdoor levels.

  38. If Mold Spores are Higher Inside ... • There is poor ventilation , or • There is indoor growth. MOLD grows on any damp surface.

  39. Indoor Moisture comes from ... • Roof Leaks • Wet pipes • Humid air • Condensation • Cooking/Baths • Damp basements

  40. Control Biological GrowthAttack the Source Keep all surfaces clean – The slightest amount of soil is a medium for mold to grow Limit or prohibit smoking Pick up water spills & leaks promptly – should be dry within 24 hours Maintain indoor plants properly

  41. Control Biological GrowthAttack the Source Maintain HVAC system properly - clean and sanitize regularly Don’t block supply vents or return grills Provide adequate supply of non polluted outdoor air Keep temperatures below optimal range Control Condensation – Proper Drainage / Pan Strips Keep relative humidity below 50%

  42. Control Biological GrowthAttack the Source Control Condensation – Proper Drainage / Pan Strips Keep relative humidity below 50% - Use Dehumidifiers

  43. IAQ Research Conclusions • IAQ complaints in classrooms are related to high relative humidity. • Carpet ... is not related to IAQ complaints.

  44. IAQ Research Conclusions • Carpet traps and holds allergens. • There is no release of allergens from carpet. • Carpet is a benefit for indoor air.

  45. Airborne allergens eventually fall down.

  46. Allergens Stay Down remain trapped in carpet fibers ...

  47. One HOST cleaning removes : • Dust mites - 78% • Dust mite allergen - 75% • Cat Allergen - 85% • Mold Spores - 85% • Bacteria is also reduced dramatically

  48. Thank YouTHE END
