3. Home Environment Health Risk Factors:
•Climate
•Building site
•Building materials & practices
•Furnishings, finishes & household products
•Resident lifestyle of greatest concern for children,
elderly & others with weakened immune systems
4. Basic principle of a healthy home is that all things
are connected.
Systems approach requiring a holistic
understanding of how home design, construction &
operational elements interact to create a dynamic
system
5. The process or act of supplying a house or
room continuously with fresh air.
The replacement of stale or noxious air with
fresh air.
The mechanical system or equipment used to circula
te air or to replace stale air with fresh air.

8. Excess moisture is a potential problem for both a
building and the people who live in it.
Excess moisture in building materials leads to
structural problems such as peeling paint & rusting
metal
9. Damp building materials tend to attract dirt &
therefore require more cleaning & maintenance.
Damp spaces make good environments for the
growth of many biological pollutants
10. Preventing problems
• Good ventilation, especially using exhausts
• Limit interior moisture sources
• Keep materials clean
• Hard surface or nonabsorbent material
• Sealers
• Vapor retarder material
• Antimicrobial finishes or additives
12. Potentially harmful materials:
• Formaldehyde & other volatile organic compounds
(VOCs) such as particle board
• Petroleum-based products such as wood finishes
• Aerosol containers
• Pesticides
13. Help to control home indoor air quality by the choices
you make in using household chemicals and products:
• Use the least amount of a product possible
• Read labels & follow safety precautions
• Do not use a potentially hazardous chemical unless
necessary
• Use household chemicals & products only for their
intended purpose
14. • Choose product packaging that reduces the chance of spills
and leaks (child-proof if needed)
• Keep household products in original containers
• Always use household products in well-ventilated areas
15. It is also a good idea to reduce the need for potentially
hazardous household chemicals in the first place by
practicing preventative maintenance:
• Clean spills & stains quickly
• Remove food wastes promptly
• Control excess moisture to reduce the likelihood of
problems with mold or household pests
16. The choices that people make affect the quality of
the air & environment in their homes
Environmental tobacco smoke (ETS), or second
hand smoke from cigarettes, pipes, or cigars, can
have devastating effects on a home and its residents
Do not allow smoking in your home
17. Household Pests
Any bug that is living in the house rather than
accidentally getting in from the outside, represents a
potential health & safety problem that should be
addressed
• Roaches can get into food and spoil it; roach feces
cause pollution of the indoor air & can be a major
trigger for asthma attacks, especially in children
18. Dust mites live all over people’s homes—in carpets,
upholstered furniture, bedding & stuffed animals
Dust mites thrive in moist places & wherever they can
feed on dead human skin cells
Many people are allergic to the feces of dust mites &
for some people they serve as a trigger for asthma
attacks
19. Pets that live indoors can result in potential health
risks to household members
Dander is the major problem
Keep pets out of carpeted areas & bedrooms
