Indoor environmental asthma may be triggered by: - Secondhand smoke - Dust Mites - Mold
ASTHMA cont. Environmental factors that stimulate asthmatic conditions: Air we breathe Surfaces we touch
INDOOR AIR QUALITY IAQ Standards Good Indoor Air Quality Poor Indoor Air Quality Resolving/Correcting
IAQ STANDARDS Climate controlled environments can improve indoor air quality
GOOD INDOOR AIR QUALITY (IAQ) Introduce/distribute adequate air ventilation Control airborne contaminants Maintain acceptable temperature and relative humidity
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.
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
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
POOR INDOOR AIR QUALITY-- Indoor Sources of Poor IAQ (cont.) Use of Building: Portions used for specialized purposes - Restaurants - Print Shops - Dry Cleaning
POOR INDOOR AIR QUALITY cont. Neglect of Maintenance -Basic custodial duties -Reports of Hazards -Basic maintenance duties
POOR INDOOR AIR QUALITY EQUIPMENT -HVAC Dust/dirt in ductwork Microbiological growth Improper use of cleaning compounds Improper venting Refrigerant leakage
RESOLVING INDOOR AIR QUALITY PROBLEMS HVAC UNIT PATHWAYS DUCTWORK PATHWAYS DUCTWORK OCCUPANTS SOURCES OF CONTAMINANTS
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
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.
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
OCCUPANTS Employees, clients, visitors –Groups possibly more susceptible: Allergic or asthmatic individuals Individuals with respiratory disease Individuals w/suppressed immune systems
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
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
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
WHAT IF I HAVE A PROBLEM? MOST IMPORTANTLY EVER DO NOT IGNORE A REPORTED COMPLAINT – EVER
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
WHAT IF I HAVE A PROBLEM? If has not been corrected within 30 days, Report to the Office of Risk Management
HIRING A PROFESSIONAL CHECK - Company/individual’s experience - Knowledge of local codes and regional climate conditions
REMEMBER: A perceived hazard can create as many problems (with employees) as a real hazard Report all suspicions of possible mold and/or asbestos
