Waste Handling, Decontamination, and Disposal
What to know
Asbestos waste is bagged in labeled, leak-tight containers (typically 6-mil or heavier polyethylene bags, double-bagged), with the bag exterior wiped or HEPA-vacuumed before it leaves the work area. Labels must identify the material as asbestos-containing and warn of the hazard; NESHAP requires specific labeling and handling for regulated asbestos-containing material (RACAM). Waste goes to a permitted landfill that accepts asbestos; manifests and disposal records are retained.
Decontamination is the worker's exit path: remove gross contamination, remove and bag coveralls in the dirty room, shower in the shower room, dress in the clean room. Equipment leaving the enclosure is HEPA-vacuumed and wiped. Water used in decon and cleanup is filtered or treated as contaminated.
Traps
Questions test whether you know waste bags must be decontaminated on the outside before transport, and that a landfill must be permitted to accept asbestos. Another trap: assuming ordinary dumpsters or recycling are acceptable, or that decon is optional for short jobs. Watch for confusion between the dirty room (remove PPE) and the clean room (dress).
Rule of thumb
Double bag, label, wipe the outside, and manifest to a permitted landfill: if the outside of the bag is dirty, it is not ready to leave.
