Why It's Important
  • Asthma is the leading cause of children’s absence from school.
  • Numerous environmental triggers can cause asthma attacks, such as:
    • Mold, excess moisture, and dust
    • Pests and animal dander
    • Diesel exhaust
    • Chemicals in some cleaning products
  • Addressing asthma triggers can reduce the number of nurse visits and keep children focused on school work.
What You Can Do
  • Perform regular and thorough cleaning and building maintenance to help children avoid environmental triggers.
  • Avoid using cleaning products containing strong odors or fragrances that might trigger asthma symptoms.
  • Implement an integrated pest management program to reduce the risk of triggers.
  • Ensure the school has policies in place to reduce unnecessary car and bus idling.
  • EPA's Model School Environmental Health Program addresses key components that can reduce asthma triggers.
