Summer Window Replacement
A school district schedules a summer window and floor replacement in a 1955 elementary school. The AHERA management plan identifies asbestos-containing glazing compound at each window and asbestos-containing 12-inch floor tile and black mastic in the corridors. The scope includes removing 28 windows (about 90 linear feet of glazing compound) and 1,200 square feet of floor tile. The district's facilities director wants to use two in-house custodians who have completed two-hour asbestos awareness training to remove the glazing compound and tile during the first week of break, arguing that it is 'small-scale, short-duration' work and cheaper than hiring an abatement contractor. The work would occur while summer school classes are in session in an adjacent wing. The district has not yet notified the state or revised the management plan.
1. Can the custodians perform this work under the O&M exception? Explain.
Read the worked answer
No. The proposed work is far beyond small-scale, short-duration O&M. Removing 1,200 square feet of floor tile and mastic and 90 linear feet of glazing compound is a renovation/abatement project, not a minor repair. Two-hour awareness training does not qualify custodians to perform abatement. The district needs an accredited abatement contractor, an accredited contractor/supervisor, accredited workers, and a project designer for the abatement design. An accredited management planner should update the management plan to reflect the project and any changed conditions. The O&M exception is for minor work such as small repairs or limited cleanup under an O&M plan, not for a corridor-wide flooring removal. Using custodians would create worker exposure, occupant exposure, and enforcement risk.
2. Identify the required project roles, notifications, and occupancy controls before work begins.
Read the worked answer
The district should engage an accredited project designer to prepare the abatement project design, an accredited contractor/supervisor and accredited workers to perform the removal, and an accredited inspector or project monitor for clearance. The district should submit the required state notification at least 10 working days before the work, update the AHERA management plan, and provide any required notice to parents and employees. Because summer school is in session in an adjacent wing, the work area must be isolated with critical barriers and negative pressure as needed, and access controlled. The adjacent wing may need relocation or additional protection if the containment cannot reliably prevent migration. Air monitoring and clearance should be completed before reoccupancy. Records should include notifications, certificates, daily logs, waste manifests, and clearance results.
3. What should the district do if it wants to remove only a 20-square-foot patch of damaged floor tile later in the year?
Read the worked answer
A 20-square-foot patch may be a candidate for O&M if the district's O&M plan covers it, the work is small-scale and short-duration, and trained custodial staff use proper methods. But the district must first confirm the material is ACM and that the patch does not become part of a larger renovation. The work should use wet methods, HEPA vacuuming, and proper disposal; workers should have the training required by the O&M plan. If the patch is part of a larger flooring replacement, or if it cannot be controlled, it becomes abatement requiring accredited personnel. The district should document the scope, method, and waste disposal and update the management plan if response actions change. The earlier corridor project cannot be split into small patches to avoid accreditation.
