Title: INDOOR AIR QUALITY


1
INDOOR AIR QUALITY
  • OFFICE OF RISK MANAGEMENT
  • LOSS PREVENTION UNIT

2
PRE-TEST
  • Name some building locations where mold can be
    seen.
  • Smoke poses no Indoor Air Quality problem.
  • T / F

3
PRE-TEST
  • Ventilation systems can control and/or cause IAQ
    problems.
  • T / F

4
GOALS
  • Understanding/Reducing Mold Growth
  • Minimize/Prevent Mold Poor Indoor Air Quality
  • Education in Prevention Recurrence

5
OBJECTIVES
  • Educate State agencies on Indoor Air Quality
    Issues
  • Provide control methods
  • Assist in addressing issues

6
INTRODUCTION
  • Keeping your workplace healthy is good business
    for employees

CAN INCREASE PRODUCTIVITY
7
  • MOLD
  • Causes Routes of Exposure
  • ASBESTOS
  • Location Health Hazards

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
  • Moisture
  • ALL Surfaces
  • Temperature

12
MOLD cont.
  • 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
    promotes condensation
  • Increased temperature--air retains more moisture
    promotes 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
  • Find/repair internal leaks ASAP
  • Watch for condensation wet spots
  • Prevent moisture/ condensation - Increase
    temperature or reduce humidity (below 60)
  • Roof/window inspectionsrepair 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. Dont let foundations stay wet
  • provide drainage

  • If you only remember one thing
  • NEVER IGNORE A COMPLAINT--
  • DO SOMETHING!

28
  • ASBESTOS

29
ASBESTOS
  • 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
ASTHMA
  • 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

  • DUCTWORK
  • OCCUPANTS

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
  • Maintain good working relationship w/Maintenance
    Dept.
  • Ensure allocation of funds for repair/maintenance
  • 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
  • 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/individuals experience
  • - Knowledge of local codes and regional climate
    conditions

61
REMEMBER
  • A perceived hazard can create as many problems
    (with employees) as a real hazard
  • Report all suspicions of possible mold and/or
    asbestos

62
