My property needs to be decontaminated, what stays and what goes?
In most cases where methamphetamine contamination levels exceed 0.5 micrograms per 100 square centimeters, all porous materials will need to be removed as they can not effectively be decontaminated. Other nonporous items may or may not be able to be decontaminated. Following is a brief guide as to the removal of contaminated materials and hazardous waste disposal.
- Removal/Disposal of all porous materials where necessary including
- Carpets, linoleum, floating laminates
- Blinds & curtains
- Non-restorable contents
- Removal/Disposal of all electrical items where necessary including
- Electrical fittings, switches, lights, ceiling fans
- Ovens, refrigerators, and dryers
- Air conditioning and ducting
- Terminate all exposed wiring
- Removal/Disposal of structural components where necessary including
- Structural components that are not cost-effective to remediate are to be removed and disposed of. This may include cabinetry, internal doors, and skirting boards, ceiling linings, gyprock with wallpaper applied, timber trimming with gloss varnish, gyprock or timber with paint or other damage that may have allowed methamphetamine to penetrate.
- Structural components may be removed and disposed of where removal is required to gain entry to enclosed low access spaces, where methamphetamine levels exceed 2.5 µg/10cm2. This may include roof cavities and crawl spaces.
- Components must be rendered unusable after removal
- Hazardous waste disposal, Methamphetamine waste can not be disposed of in regular landfills. Waste disposal must be carried out as per the instructions from a hazardous waste disposal contractor that is licensed by the EPA
