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

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

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?

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

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

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...

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

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

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

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

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

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

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

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

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

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

DUST

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.

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

WALKS in the door Over 85% of Building Dust

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

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

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

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

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

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

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

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

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

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%

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