The New Zealand Ministry of Business, Innovation and Employment has released a guidance document with the purpose of reducing people’s risks of exposure to harm caused by the presence of unacceptable levels of methamphetamine contamination in properties. It was developed by a committee of experts across relevant industries in the public and private sector, including central and local government. The new Standard is NZS8510:2017 Testing and Decontamination of Methamphetamine-Contaminated Properties.
Application of the Standard provides assurance that screening, sampling, testing, assessing and decontamination of contaminated properties and disposal of their contents are carried out following good practice. Drug Smart is adopting the recommendations set out in the Standard and we are happy to answer any queries you may have regarding these changes and how they relate to your situation.
The Standard separates property into high-use and limited-use areas. High-use areas are easily accessed and are regularly used by adults and children. In these areas the maximum acceptable level of methamphetamine in an affected property is 1.5μg/100cm2. This means that if the test result for an area is above this level then it must undergo decontamination action to reduce the level of contamination to
1.5μg/100cm2 or below.
Limited-use areas are likely to be accessed only by adults and for short periods of time, for example crawl spaces and ceiling cavities. These areas have a contamination threshold of 3.8μg/100cm2. It should be noted, however, that if a limited-use space is contaminated above 1.5μg/100cm2 then this space should not be used to store personal or household items as these could become contaminated to an unacceptable level.
