“Burrito wrapping” is a method used to contain and transport asbestos-containing materials (ACM) to prevent the release of asbestos fibers during removal and disposal of debris. Wildfire debris was not required to be burrito wrapped until the 2020 fire season. Following the 2020 fires, it became common practice and, in most jurisdictions, a requirement of clean up. In August of 2023, the Gray Fire in Medical Lake and the Oregon Road Fire in Elk brought safe clean up of debris to the forefront and illuminated the massive costs of proper asbestos testing and removal. Funds and programs were supported by the State to help with the proper removal of debris, with burrito wrapping being the primary system used. Medical Lake and the Spokane Region Long Term Recovery Group was one Washington State’s most intensive clean-up programs. It is important that post fire debris is not moved prior to testing for asbestos.
Burrito Wrapping Steps:
- Wetting or coating the item with water to prevent asbestos fibers from becoming airborne.
- Carefully wrapping the items in a leak-tight container(s), often a 6mm plastic bag, to ensure the fibers are contained.
- Sealing all ends with duct tape and attaching asbestos warning labels and other required markings.
- For larger items or materials, the container(s) may be placed in a larger plastic liner or tarp and “burrito” wrapped, ensuring complete encapsulation.
