Asthma and Air Quality
Asthma is a serious problem in our society. It kills about 4,000 people a year. Asthma
is the leading chronic illness of children in the United States and the leading cause of
school absenteeism due to chronic illness. Asthma deaths and the number of Americans
diagnosed with asthma continue to increase each year. Asthma can be aggravated by exposure
to pollutant "triggers" such as certain components of vehicle exhaust and
industrial emissions, tobacco smoke, pollen and allergens from animals and insects.
Asthma affects children disproportionately. Five times more children than adults die
from asthma each year. Engineers can help prevent asthma episodes by reducing or avoiding
exposure to potential triggers such as pollution.
Simple Steps for Reducing or Avoiding Pollutants That May Trigger Asthma Episodes
- Clean or change filters every month during periods of use. Consider installing higher
efficiency filters to reduce the number of particles in the air.
- Try to keep humidity levels between 30 and 50%, because high humidity can promote growth
of biological agents that may trigger asthma episodes.
- Use exhaust fan or open windows in kitchen or bathroom areas.
- Keep the school clean to reduce allergy-causing agents like microscopic dust mites,
animal dander, and pollen.
- Get rid of cockroaches.
- Some people with asthma may be sensitive to allergens from classroom pets such as birds
and gerbils. Keep cages clean and don't let animals roam.
- Strong-smelling chemicals in laboratories or art supplies can trigger asthma episodes.
Make sure ventilation is adequate.
- Gyms, locker rooms, and libraries may be a source of dust and mold; make sure they are
cleaned regularly and humidity levels are kept between 30 and 50%.
