Waste Handling, Transport, and Disposal
What this domain tests
This domain tests how asbestos waste is wetted, packaged, labeled, stored, transported, manifested, and disposed of. Expect questions about bag thickness, double-bagging, sharp debris, visible dust, and whether a dumpster or ordinary landfill is acceptable.
Core rules and concepts
- Keep waste wet and package it in leak-tight containers. Asbestos waste is commonly double-bagged in 6-mil bags, sealed, and placed in a rigid container if it contains sharp objects or heavy debris.
- Label each container with the generator's name and address, an asbestos warning, and the date. Containers must show no visible dust and must be handled without tearing or compressing the contents.
- Store waste in a secured, covered area. Do not leave bags outside overnight where they can be weathered, punctured, or accessed. Do not put asbestos waste in an ordinary open dumpster.
- Transport must follow DOT requirements for the shipment and any state or local requirements. NESHAP requires disposal at a landfill that meets 40 CFR 61.154; in Hawaii, use a permitted solid waste facility.
- Where a waste manifest or shipment record is required, complete it accurately and retain copies. Record the quantity, date, transporter, and disposal facility.
- Do not compact, incinerate, recycle, or salvage asbestos waste unless the specific method is authorized.
Worked example
A contractor generates 15 bags of pipe insulation and plans to stack them outside the containment overnight. What must be done?
Reasoning: the bags must be sealed, labeled, and free of visible dust. If they must remain on site, store them in a secured, covered area or inside the containment with weather protection. Do not leave them exposed or in an open dumpster. Arrange transport and disposal at a permitted facility, and complete the required waste records. If a bag is torn, rewet, re-bag, and clean the area before moving it.
Traps that cost marks
- Single-bagging or using thin, unlabeled bags.
- Putting asbestos waste in a regular dumpster or leaving it uncovered outside.
- Ignoring sharp debris that can tear bags.
- Shipping without DOT-required packaging or paperwork.
- Disposing at a non-permitted landfill.
- Failing to retain manifests or shipment records.
