A Fallen Ceiling Tile and a Gouged Pipe
At a K-12 school built in 1968, the AHERA management plan identifies friable asbestos-containing pipe insulation on boiler-room elbows and nonfriable asbestos in 9-inch floor tile and mastic. The last three-year reinspection was completed 39 months ago; the six-month periodic surveillance is current. On a Friday afternoon, a custodian accidentally gouges about 3 square feet of pipe insulation while moving a cart, and a 2x4 ceiling tile in a nearby classroom falls and breaks. The tile is not listed in the management plan as asbestos-containing, but the plan notes that ceiling tiles in that wing are 'presumed ACM' pending sampling. The principal asks the custodian to vacuum the debris with the school's shop vacuum and bag it before students return Monday. The district's O&M plan allows small-scale, short-duration repairs by trained custodial staff.
1. Evaluate the custodian's proposed response for the gouged pipe insulation and the fallen tile. Identify what may be handled as O&M and what may not.

The shop vacuum is not acceptable for either debris pile unless it is a HEPA vacuum. Dry vacuuming with an ordinary shop vacuum can disperse fibers. The 3 square feet of gouged friable pipe insulation may fall within small-scale, short-duration O&M if the district's plan covers it, the custodian is trained, and the work uses wet methods, HEPA vacuuming, proper PPE, and prompt bagging. If the repair is more than minor or cannot be controlled, an accredited worker and supervisor should do it. The fallen ceiling tile is presumed ACM; the area should be isolated, debris wetted and HEPA-vacuumed or wet-wiped, and the tile sampled or treated as ACM. If the damage is more than a minor repair, it is abatement, not O&M. Students should not return until cleanup is complete and the area is visually clean.
2. What AHERA requirement is overdue, and what effect does that have on the management plan?
Read the worked answer
The three-year reinspection is overdue: the last one was 39 months ago. Six-month periodic surveillance does not replace reinspection. The district must arrange a reinspection by an accredited inspector, then have an accredited management planner update the management plan based on the findings. The plan should be revised if conditions, response actions, or presumed ACM designations change. The district should document the overdue status, schedule the reinspection promptly, and notify parents and employees as required. Until the reinspection and plan update are complete, the district should continue O&M and surveillance and should not treat the existing plan as permanently sufficient. The fallen tile also shows why presumed ACM in the plan needs a clear response procedure.
3. What records and notifications should be completed before the classroom is reoccupied?
Read the worked answer
The district should record the incident, the location, the materials involved, the cleanup method, who performed it, and the final visual inspection. If the response is O&M, the record should show that it fit the O&M plan and that trained staff used HEPA equipment and wet methods. If the response is abatement, the district needs the required state notification, accredited personnel, waste disposal records, and clearance before reoccupancy. The district should also consider whether the annual AHERA notification to parents and employees needs updating because of the incident or the overdue reinspection. In either case, do not reoccupy the classroom until debris is removed and the area is visually clean; if there is uncertainty about the tile, treat it as ACM until sampling by an accredited inspector shows otherwise.
