1 Action Kit

2 IAQ Basics IAQ Management Plan Resolving IAQ Problems Appendices - - - -

3 Action Kit Overview n IAQ Coordinator needed n Less expense and effort to prevent problems than resolve n IAQ problems can be prevented by educating staff and students about factors that create them

4 Importance n Indoor pollutants 2 - 5 times higher than outdoor n People spend 90% of their time indoors

5 Importance n Decrease health complaints u Cough u Eye irritation u Headache u Asthma episodes u Allergic reactions u Severe asthma attacks u Legionnaire’s disease u Carbon monoxide poisoning

6 Importance n Reduce spread of infectious disease n Produce favorable learning environment n Increase productivity n Reduce absenteeism n Better maintenance of equipment

7 Importance n Improve relationships n Reduce liabilities

8 IAQ Coordinator n Team leader

9 IAQ Coordinator n Implements the IAQ Management Plan (Sections - ) n Prepares and coordinates emergency response (Sections - )

10 IAQ Coordinator n Central information location u Complaints u Information l Renovation projects l HVAC activities l Chemical use

11 Team Members n Faculty u Art, science, etc. classes generate sources n Staff u Printing/office equipment generates sources u Temperature/humidity controls n HVAC personnel

16 Understanding IAQ n Sources u Inside, outside, or from mechanical system u Can vary by time and location u Appendix lists by contaminant and describes sources

17 Sources* n Occupants u CO 2 u Bioaerosols u Heat u VOCs l Hairspray l Dry-cleaning solvents l Perfume

18 Sources* n Standing water/floods u Mold u Bacteria n Combustion u CO u CO 2 u NO X (diesel) u Particulates u Heat

25 Understanding IAQ n HVAC system u Takes in fresh air u Mixes with return air u Filters u Tempers l Temperature l Humidity u Distributes n Video

26 Understanding IAQ n HVAC system u Central air u Unit ventilator (fan coil unit)

27 IAQ Backgrounder (4)

28 IAQ Backgrounder (3)

29 IAQ Backgrounder (5)

30 IAQ Backgrounder (3) Supply only Usually a return Could be either

31 Understanding IAQ n Thermal comfort u Temperature u Humidity

32 Thermal Comfort (11)


34 Understanding IAQ n Ventilation for occupant needs u ASHRAE Standard 62 l Contaminant concentrations l Fresh air supply

35 Fresh Air Ventilation Recommendations (12)

36 Understanding IAQ n Pollutant (and fresh air) pathways u Air flow u Positive/negative pressure u Blockage l Covered ducts l Cubicles

37 Understanding IAQ n Occupants u Susceptibility l Allergy/asthma l Chemical sensitivity l Respiratory disease l Suppressed immune system l Contact lenses l Heart disease (CO) l Children (tobacco smoke)

38 Understanding IAQ n Complaints u Headache u Fatigue u Shortness of breath u Sinus congestion u Coughing u Sneezing u Eye/nose/throat/skin irritation u Dizziness u Nausea

39 Understanding IAQ n Causes other than IAQ u Thermal comfort (hot causes fatigue) u Lighting/glare (causes headaches) u Job stress u Illness clusters (get health department and/or medical* advise)

40 Other Causes* n Do not dismiss because YOU think there is no IAQ problem without fully investigating n Act of investigating may mitigate problem n Investigation may uncover “root” cause, which should be discussed with supervisor

41 IAQ Management Plan n Fix any existing IAQ problems n Instill IAQ awareness for prevention n Resolve IAQ issues as they occur

42 IAQ Management Plan n Select IAQ Coordinator n Become familiar with kit

43 IAQ Management Plan n Gain top administrative support u Note to School Officials (page i of guide) u IAQ Backgrounder u Sections,, u Supposed to be little or no impact on school budget/ time resources (except for ventilation checklist)

44 IAQ Management Plan n Obtain information on radon* n Obtain information on integrated pest mgmt. u Reduce use of chemicals u EPA 735-F-93-012 n Obtain information on lead* n IAQ Checklist interval u 1-2 times/year

45 IAQ Management Plan n Plan for emergency response n Inform appropriate committees and groups u PTA u Safety Committee u Staff/Faculty Senate* u Employee Liaison*

46 IAQ Management Plan n Establish written policies as needed u Smoking u Pest control u Ventilation system operation u Painting u Spill response* u Chemical use* (Checklist on page 5-6 of IAQ Coordinator’s Forms tab)

47 IAQ Management Plan n Assess Current Status u Start the Checklists Log (page 9 of IAQ Coordinator’s Forms tab) u Decide who will get Action Packets (checklists + info) l Teachers l Staff l Facility operators l Custodians l Health officers l Log tracks checklist returns
