We are all too familiar with the effects of outdoor air pollution such as smog and particulate matter (pollen, soot, dust, etc) on our health. However, most of us are unaware of the pollution that exists indoors. Since most children spend a great deal of time indoors, the quality of the air they breathe is extremely significant. Be alert of the following indoor air pollutants:

Second-hand Smoke:
The greatest threat to the quality of indoor air is tobacco smoke. Although smoking is prohibited in many indoor facilities according to city by-laws in certain areas, without exception, smoking must not be permitted in any child care facility. 

Carbon Monoxide:
This colourless, odourless, tasteless, but treacherous gas that results from the burning of fuel can seep into your child care facility from many sources including idling cars, gas ranges, fireplaces, poorly adjusted or unvented gas stoves, slow burning wood stoves and kerosene heaters. High levels of carbon monoxide can cause lung ailments, impair vision, headaches, dizziness, nausea and weakness. New facilities by law must have a carbon monoxide detector, if your facility does not, have a carbon monoxide detector installed immediately. Carbon monoxide detectors can be purchased at your local hardware store or home improvement store.

Radon:
This colourless, odourless, radioactive gas is a naturally occurring product of the decay of uranium in rocks and soil. Radon can be found in soil, building material, natural gas and water. The greatest concentration of radon is found in the basement or ground floor of buildings. High levels of radon over many years can cause lung cancer. To determine if your facility has high levels of radon, purchase a radon test kit from your local hardware store or home improvement store.

Formaldehyde:
This gas can be found in the resins in particleboard furniture, decorator fabrics and the adhesives in carpeting. The levels of formaldehyde gas released are at their highest when an item is new, however the gas continues to be released throughout the years. High levels of formaldehyde gas can cause nasal cancer, respiratory problems, rashes and nausea. To reduce levels of formaldehyde gas in your facility, purchase formaldehyde-free products. Also, indoor plants (approximately 15-20) can apparently absorb the formaldehyde gas in a 1, 600 square foot facility.

Asbestos:
Asbestos was once used on ceilings, pipes and other surfaces in buildings. It is no longer used in new construction because it causes cancer and serious lung problems. If you suspect that your facility may have asbestos-lined building materials, contact your local health department immediately. Do not attempt to remove it yourself. Have a professional examine your facility and perform the necessary removal.

Miscellaneous Fumes:
Fumes from cleaning fluids, aerosol sprays, turpentine and other painting-related materials can be highly toxic. Always use these products in a well-ventilated area and never use them when children are nearby. Once used, store in a safe place and out of children's reach.
