  3. IAQ Jeopardy Ventilation 100 Studies show that over half the time indoor air quality problems are due to inadequate ventilation. True or False NIOSH Study - U.S. Dept. of Labor OSHA Technical Manual

  4. Inadequate ventilation in a classroom can cause the level of what air contaminant to increase? Carbon Dioxide (CO2) Levels about 700 ppm above outside levels are recommended by ASHRAE. Ventilation 200

  5. Ventilation 300 You respond to an IAQ complaint from this office. Determine the primary problem with this environment that may affect IAQ. Ventilation 300 This is an old shower room that was converted into a workstation. No supply air ventilation.

  6. Ventilation 400 Below is an HVAC schematic of supply and return air locations in a classroom. Discuss potential IAQ problems with this setup. No Air Short –Circuiting No Air No Air

  7. By studying approximately 500 indoor air quality investigations, the National Institute for Occupational Safety and Health (NIOSH) identified primary sources of indoor air quality problems and derived percentages of occurrence. Using the available percentages to the right of the Table, correctly complete the Table below. Ventilation 500 5 % 52 % 16% 52 % 10 % 16 % 5 % 10 % Reference - U.S. Dept. of Labor (OSHA Technical Manual)

  8. Mold growing on indoor building materials is natural and should not be investigated. True or False Clean up the mold Fix the water problem Dry out the area Mold 100

  9. If you find mold indoors it is generally a good idea to have it tested to see what type it is. It’s more important to find the water source, fix it, and clean up the mold. Mold 200 True or False

  10. Mold is everywhere No government standards identifying acceptable or hazardous levels Different levels of sensitivities between individuals Testing methods are not standardized Although it can be very expensive, sampling for airborne mold is the most reliable method for determining whether you truly have a mold problem or not.True or False Mold 300

  11. What two main things are needed for mold to grow? Water Food (plywood, drywall, furring strips, carpets, and carpet padding, papers) Optimal Temperatures (70-90o F) (Mold can grow in 32-120o F) High humidity (above 50%) Stagnant Air Mold 400

  12. Mold 500 You identify 35 Square Feet of Mold contaminated Wallboard. Review the following work practices and decide which are considered Good or Bad. Good Good Bad Good

  13. Asthma 100 For some, Asthma is a psychological condition and is not a real health hazard. True or False

  14. List 3 potential Asthma Triggers • Cigarette smoke • Pet dander • Mold • Dust • Various Chemicals • Perfumes, Fragrance • Pollen • And many more Asthma 200

  15. Asthma 300 According to the CDC, Asthma accounts for 1 million lost days of school each year. 14 Million True or False

  16. According to the CDC, if a child with asthma wants to play with a stuffed toy it should be washed in hot water (about 130 degrees to kill mites) • Every 2 Weeks • Every 2 Months • Every year • Never, just thrown away when soiled. Asthma 400

  17. List 3 things your school can do to help control asthma triggers • Ventilate well • Control dust • Keep the school dry • Don't keep pets in classrooms • Pest Management : Prevent insects and other pests from entering • Practice good chemical management Asthma 500

  18. Is odor an indication of a hazard? Investigation / Testing Methods 100 Not Always

  19. Investigation / Testing Methods200 You receive an odor complaint believed to be caused by the restroom. What is a simple test that can be done to see if the restroom’s HVAC is functioning properly?

  20. Are elevated CO2 levels a health hazard? YES or NO Investigation / Testing Methods300 Goal for classroom: 1000-1200 ppm Dept of L&I 8-hour exposure limit is 5000 ppm Levels up to 10,000 parts per million can be tolerated without ill effects by healthy people.

  21. If you receive a complaint about IAQ what are some things you can evaluate? Investigation / Testing Methods400 • Vents are clear/ Check with EMS • Clutter in the classroom/stuffed animals • Recent water damage/stains on ceiling tiles or walls • Unapproved chemical use • Drain traps • Air fresheners • Check the refrigerator

  22. Investigation / Testing Methods 500 This is the most important step in identifying a potential IAQ problem. Visual Inspection Or Site Visit

  23. View the image and name this. Common Sources 100 Dust Mite FACTS Live on dead skin shed from humans and pets Beds, pillows, stuffed animals, upholstery are prime habitats for dust mites The feces and skin shedding of the dust mites cause the allergic reaction, not the mite itself

  24. Common Sources 200 Name three potential sources or conditions in Mr. H’s classroom that could negatively impact IAQ.

  25. Common Sources 300 Study the photo and identify a condition that could affect IAQ Air Intakes

  26. Common Sources 400 Ozone generating air cleaners actually do reduce indoor particulate levels and can reduce occupant symptoms. True or False However, Ozone is a respiratory irritant and these types of air cleaners should not be used in occupied spaces.

  27. Cover up odor by numbing our sense of smell About 95% of these synthetic compounds are made from petroleum products Fragrances can trigger asthma and other respiratory conditions due to the irritant effect Can these help clean the air? Common Sources 500 NO
