Indoor Air Quality
The Indoor Air Quality program has three main functions.
1) Enforce 410 IAC 33 “Indoor Air Quality in Schools and State Agencies”. When we receive a complaint about the air quality in a school or state agency we will inspect the facility and report our findings.
2) Provide technical assistance to local health departments in support of their investigations. We have instrumentation that we can use to measure various indoor air pollutants. This information is then provided to the local health department to aid in their investigations.
3) Educate and consult with the public regarding their concerns for Indoor Air Quality. If you have questions on indoor air quality that are not answered on these web pages you can contact our office and we will be happy to answer your questions.
Beyond 410 IAC 33 for schools and state agencies there are no laws or regulations that can be enforced for indoor air quality. There are several published guidelines from federal agencies and other organizations that can be used to make suggestions and recommendations to improve a building’s air quality.
Schools and State Agencies
The ISDH will inspect a school or state agency to ensure they are in compliance with 410 IAC 33.
Indoor Air Quality Best Practices for Schools:
The State Dept. of Health has created several best practices resource documents to assist schools in meeting the requirements of 410 IAC 33.
Have questions about “Toxic Black Mold”?
Do NOT use a broom or vacuum to clean up a mercury spill. It will spread the mercury and increase your exposure to the mercury vapor. If you break a mercury thermometer or have a mercury spill and have questions you can contact our office at 317.351.7190, or call the Indiana Department of Environmental Management’s Emergency Response 24 hour spill line at 888.233.7745
This cleanup guide was written for schools but can be useful for residential cleanup of small amounts of mercury such as from a broken thermometer.
Formaldehyde is found in a wide range of products from permanent press fabric to composite wood products. Formaldehyde can cause irritation of the skin, eyes, nose, and throat. High levels of exposure may cause some types of cancers.
