The long awaited NZS 8510:2017 Testing and decontamination of methamphetamine-contaminated properties has been released. The purpose of this standard is to provide guidance on reducing people’s risks of exposure to harm caused by the presence of unacceptable levels of methamphetamine contamination in properties including vehicles and caravans. It establishes contamination levels to guide the decontamination of affected properties. It also sets out procedures for testing properties for contamination and the steps needed to decontaminate and dispose of any contaminated waste. Reference to this standard may be helpful in situations such as change of ownership or tenancy of properties particularly properties where contamination by methamphetamine is known or suspected.
