8. MOLD Definition : Organic substance that requires oxygen & water to grow. Mold breaks down plant matter by digesting for food.

9. WITHOUT MOLD: We would be struggling w/large amounts of dead plant matter. We would not have penicillin

10. MOLD cont. All mold spores cannot, practically, be eliminated indoors Can be managed by controlling indoor moisture

11. MOLD cont. Growth Factors: 1. Moisture 2. ALL Surfaces 3. Temperature

12. MOLD cont. 1.Moisture: –Leaks in pipes, roof, windows, etc. –HVAC systems

13. MOLD cont. 2. Any Surfaces : Mold can exist on any surface!!! Examples include Wood Paper Carpet Food Plastic Rock

14. MOLD cont. 3. Temperature : Decreased temperature--air holds less moisture; p romotes condensation Increased temperature--air retains more moisture; p romotes humidity

15. MOLD cont. ROUTES OF EXPOSURE Sources that allow mold indoors: - Ventilation Systems - Papers & Books - Leaks Attics Behind Walls Ceilings Under Carpeting Behind Furnishings

16. MOLD-- ROUTES OF EXPOSURE cont. Routes of Indoor Exposure

17. MOLD Preventing/Reducing Mold Growth: 1. Find/repair internal leaks ASAP 2. Watch for condensation & wet spots 3. Prevent moisture/ condensation - Increase temperature or reduce humidity (below 60%) 4. Roof/window inspections–repair leaks ASAP

18. MOLD Preventing/Reducing Mold Growth cont. 5. Regular building/HVAC inspections & maintenance 6. Keep heating & HVAC drip pans clean & flowing properly 7. Don’t let foundations stay wet – provide drainage

27. If you only remember one thing: NEVER IGNORE A COMPLAINT-- DO SOMETHING!

28. ASBESTOS

29. Mineral fiber used in construction of insulation AND as a fire retardant Found in: –Older buildings –Pipe & furnace insulation –Millboard –Floor tiles

30. ASBESTOS cont. DANGEROUS ASBESTOS FIBERS ARE TOO SMALL TO BE VISIBLE If inhaled, can remain, accumulate in lungs & can cause: Lung cancer Mesothelioma Asbestosis

31. ASBESTOS cont. Do not cut, rip, or sand asbestos-containing materials Inspect for damage or deterioration Repair or removal should be done by a professional Suspect asbestos, have professional check

32. POSSIBLE ASBESTOS/LEAD EXPOSURE Identify aspects of projects: Redecorating, renovation, remodeling Relocation of personnel or functions New construction

33. ASBESTOS cont. If you suspect presence of asbestos: DO NOT DISTURB!!!!

34. ASTHMA

35. Indoor environmental asthma may be triggered by: - Secondhand smoke - Dust Mites - Mold

36. ASTHMA cont. Environmental factors that stimulate asthmatic conditions: Air we breathe Surfaces we touch

37. INDOOR AIR QUALITY IAQ Standards Good Indoor Air Quality Poor Indoor Air Quality Resolving/Correcting

38. IAQ STANDARDS Climate controlled environments can improve indoor air quality

39. GOOD INDOOR AIR QUALITY (IAQ) Introduce/distribute adequate air ventilation Control airborne contaminants Maintain acceptable temperature and relative humidity

40. VENTILATION HVAC systems typically mix outside air with recirculated indoor air. To conserve heat and a/c, offices typically use a mix of about 20% fresh and about 80% recirculated air.

41. POOR INDOOR AIR QUALITY Indoor Sources of Poor IAQ: Disturbances of asbestos and/or lead, and formaldehyde (in pressed wood products) Carpet Copy machines Dirty ventilation systems Water-damaged walls

42. POOR INDOOR AIR QUALITY-- Indoor Sources of Poor IAQ (cont.) Ventilation Systems: Poorly designed, operated or maintained Not being used to conserve energy Spreading contaminants through building

43. POOR INDOOR AIR QUALITY-- Indoor Sources of Poor IAQ (cont.) Use of Building: Portions used for specialized purposes - Restaurants - Print Shops - Dry Cleaning

44. POOR INDOOR AIR QUALITY cont. Neglect of Maintenance -Basic custodial duties -Reports of Hazards -Basic maintenance duties

45. POOR INDOOR AIR QUALITY EQUIPMENT -HVAC Dust/dirt in ductwork Microbiological growth Improper use of cleaning compounds Improper venting Refrigerant leakage

46. POOR INDOOR AIR QUALITY External Sources : –Pollen, dust, fungal spores –Industrial pollutants –General vehicular contamination vehicle exhaust fumes and gases

47. POOR INDOOR AIR QUALITY External Sources (cont.) Emissions from nearby sources: –Dumpsters –Parking areas or garages –Loading docks –Roads

48. RESOLVING, CORRECTING, & REMEDIATION

49. RESOLVING INDOOR AIR QUALITY PROBLEMS  HVAC UNIT  PATHWAYS  DUCTWORK  PATHWAYS  DUCTWORK  OCCUPANTS  SOURCES OF CONTAMINANTS

50. Resolving Air Quality Problems HVAC System Operation & Maintenance Operate system in manner consistent w/design Maintenance & inspections on regular basis Record Keeping All HVAC problems & routine maintenance & inspections Document complaints & remedies

51. Resolving Air Quality Problems Pollution Control Identify sources Implement removal and/or remedy Occupant Activities Eliminate activities that restrict air movement Building Maintenance Activities Increase # of air exchanges per hr/per day based on daily operation.

52. Resolving Air Quality Problems Ventilation Standards & Codes Keep abreast of revisions to standards & building codes Energy Conservation Re-examine practices w/regard to IAQ, employee health, & productivity costs

53. OCCUPANTS Employees, clients, visitors –Groups possibly more susceptible: Allergic or asthmatic individuals Individuals with respiratory disease Individuals w/suppressed immune systems

54. WHAT ALL EMPLOYEES CAN DO TO PROVIDE GOOD IAQ Do not block air vents or grilles Comply with no smoking policy Clean up water spills promptly Report water leaks immediately Store & dispose of food properly

55. WHAT MANAGEMENT CAN DO TO PROVIDE GOOD IAQ 1.Maintain good working relationship w/Maintenance Dept. 2.Ensure allocation of funds for repair/maintenance 3.Coordinate design, operation & maintenance of HVAC

56. WHAT MANAGEMENT CAN DO TO PROVIDE GOOD IAQ 4. Integrate IAQ concerns into Purchasing Policies 5. Work w/contractors & maintenance BEFORE remodeling and/or renovations 6. Support employee concerns

57. WHAT IF I HAVE A PROBLEM? MOST IMPORTANTLY EVER DO NOT IGNORE A REPORTED COMPLAINT – EVER

58. WHAT IF I HAVE A PROBLEM? 4 steps to Combating Poor Indoor Air Quality: –Solve water problem –Get suspected area tested –Vacate people near area suspected –Get professional remediation help

59. WHAT IF I HAVE A PROBLEM? If has not been corrected within 30 days, Report to the Office of Risk Management

60. HIRING A PROFESSIONAL CHECK - Company/individual’s experience - Knowledge of local codes and regional climate conditions
