Indoor Air Quality from Underwriters Lavatories

With Indoor Air Quality identified as a risk to public health, UL is advancing new testing methods, new insights and new equipment that are helping minimize its adverse effects. We are researching the effects of flame retardants on the environment and creating advances in environmental chambers that enable equipment of all sizes to be tested for chemical emissions. UL is also innovating ways to measure toxicity of both volatile organic compounds and semi-volatile organic compounds. Specifically, our work with phthalates resulted in the creation of a first-of-its-kind technique involving the collection of indoor air in specialized sorbent tubes, followed by gas chromatography mass spectrometry analysis.

Quick Facts...

  • Indoor air quality can be worse than that of outdoor air.
  • Problems can arise from moisture, Insects, pets, appliances, radon, materials used in household products and furnishings, smoke, and other sources.
  • Effects range from minor annoyances to major health risks.
  • Remedies include ventilation, cleaning, moisture control, inspections, and following manufacturers' directions when using appliances and products.

Research has shown that the quality of indoor air can be worse than that of outdoor air. Many homes are built or remodeled more tightly, without regard to the factors that assure fresh and healthy indoor air. Our homes today contain many furnishings, appliances and products that can affect indoor air quality.


Air Quality for Appartments

Apartments can have the same indoor air problems as single-family homes because many of the pollution sources, such as the interior building materials, furnishings, and household products, are similar. Indoor air problems similar to those in offices are caused by such sources as contaminated ventilation systems, improperly placed outdoor air intakes, or maintenance activities.

EPA on Indoor Pollution

(From EPA website original post here... http://www.epa.gov/iaq/ia-intro.html)

If too little outdoor air enters a home, pollutants can accumulate to levels that can pose health and comfort problems. Unless they are built with special mechanical means of ventilation, homes that are designed and constructed to minimize the amount of outdoor air that can "leak" into and out of the home may have higher pollutant levels than other homes.
