1. Healthy Homes Overview Ventilation

2. Learning Outcomes Upon completion of this module you will be able to:  Identify the basic operating principle of ventilation  Recognize some of the health impacts of poor ventilation  Determine what is known as the ‘silent killer’

3. Basic Operating Principle Of Ventilation  The replacement of stale or noxious air with fresh air  Requires air exchange between the interior and exterior of the building  Ventilation can reduce:  Moisture  Environmental tobacco smoke (ETS)  Mold spores  Carbon monoxide  Volatile organic compounds (VOCs)  Radon

4. Ventilation  Poor ventilation can result in increased incidences of:  Colds  Influenza  Pneumonia  Bronchitis  Respiratory irritation

5. Exhaust Ventilation  Bathrooms  Clothes dryers  Kitchen ranges  Boilers  Furnaces  Hot water heaters

6. Kitchen Ventilation  Decreases:  Moisture and odors  Carbon monoxide (gas ranges)  Gas ovens or ranges must vent to the outdoors

7. Carbon Monoxide (CO)  Gas stoves or furnaces can give off CO  Charcoal grills, gas space heaters, portable kerosene heaters give off CO (do not use indoors!)  CO is a ‘silent killer’

8. Carbon Monoxide (CO) Alarms  Place near sleeping area  Place on all floors of home for better protection  Do not install above or beside fuel burning appliances

9. Summary In this module we have discussed:  The basic operating principle of ventilation  Some of the health impacts of poor ventilation  Carbon monoxide, what is known as the ‘silent killer’
