MO Asbestos Abatement study guide
MO Asbestos Abatement · Work through your exam, one topic at a time.
The Missouri Asbestos Abatement Certification is a state credential administered through the Missouri Department of Natural Resources (MoDNR) for people who work on asbestos demolition, renovation, and abatement projects. The department's own navigation describes its asbestos program simply as "Demolition, renovation, abatement projects and notifications." That one line tells you who the credential serves: contractors, supervisors, and workers on Missouri projects where asbestos-containing material will be disturbed, plus the people who file the required project notifications with the state. This independent study page is not affiliated with MoDNR and does not issue any credential. The exam is organized around two equally weighted domains. Topics on this exam: Asbestos regulations and notification requirements for demolition, renovation, and abatement projects and Asbestos abatement work practices, safety, and compliance. The MO Asbestos Abatement study guide has 2 sections and about 814 words.
01Missouri Asbestos Regulations and Notification
Missouri's asbestos program is built on 10 CSR 10-6.250, which implements the federal NESHAP (40 CFR Part 61, Subpart M). The rule covers demolition and renovation of facilities and asbestos abatement projects. The Missouri Department of Natural Resources (MoDNR) Air Pollution Control Program receives notifications; local air agencies may have separate requirements, so check the site location. For renovation or abatement, notification is triggered when the project removes or disturbs at least 260 linear feet of RACM on pipes, 160 square feet on other components, or 35 cubic feet when length or area cannot be measured.

Missouri's rule and NESHAP require asbestos to be removed using wet methods, HEPA vacuuming, and work practices that prevent visible emissions. Dry sweeping, compressed air, and dropping or throwing debris are prohibited. Before demolition, RACM must be removed. On pipes, glove bags or enclosed glove boxes are common; on large areas, build critical barriers, seal openings and HVAC, and maintain a negative-pressure enclosure with HEPA filtration.
