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

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

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

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

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

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

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

12. INADEQUATE VENTILATION New Construction: Reduced Air Exchange... 80% of HVAC Systems are improperly installed and maintained

13. IAQ INDOOR CONTAMINATES

14. Common Pollutants Become Trapped Indoors l Odors (VOCs) l Dust l Allergens (biological)

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

16. Compare Product VOCs VOCs (mg/m 2 ) Total Release in First 24 Hours. Air Quality Sciences, Inc.

17. VOCs of Installed Carpet VOCs (mg/m 2 ) Days After Installation

18. VOCs of Floor Adhesives VOCs (mg/m 2 ) Floor Covering Adhesive Air Quality Sciences, Inc. Total Release in First 24 Hours Floor Covering Adhesive

19. 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

20. 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

21. 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

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

24. Problems n Clogs and blockages n Slow Drains n Odor Drain Maintenance

26. 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

27. DUST

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

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

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

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

32.  Dust Mites & Cockroaches  Mold - airborne spores  Cats & Dogs - airborne dander

33. YOU CAN’T SEE ALLERGENS... you can only see you can only see the reactions to them. the reactions to them.

34. Allergic Reactions Allergic Reactions n sneezing n runny nose n congestion n headache n fatigue n nausea n sore throat n asthma attack

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

38. COCKROACHES n Found in food areas, grease traps … and in general distribution around food service areas.

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

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

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

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

45. Control Biological Growth Attack 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

46. Control Biological Growth Attack 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% below 50%

47. Control Biological Growth Attack the Source  Control Condensation – Proper Drainage / Pan Strips  Keep relative humidity below 50% - Use Dehumidifiers below 50% - Use Dehumidifiers
