Specialist cleaners face significant hazards when decontaminating properties affected by methamphetamine. These risks include aggressive dogs, squatters, property theft, and furniture booby-trapped with needles.
Before entering a site, cleaners perform drug sweeps to ensure no people or dangerous dogs are present. They must also conduct health and safety assessments and review the agreed scope of work.
The process often begins with waste removal, which can take two to three days during summer due to heat and personal protective equipment. Common contaminated areas include kitchens, laundries, and bathrooms.
Decontamination involves HEPA vacuuming, chemical treatments, and cleaning surfaces such as walls, ceilings, and plumbing. Once cleaned, the property is dried and undergoes independent testing to ensure contamination is below the threshold.
