As part of the introduction of the NZS8510 a revision was conducted on the contamination levels that were in place. It was determined that it would be safe to lift the levels for contamination to the levels listed below. Any areas above these levels are determined uninhabitable and require decontamination by an experienced decontamination company, using a product that has been determined as fit for purpose.
- 1.5 µg/100cm2 – Dwelling either use or Manufacture all high use areas
- 3.8 µg/100cm2 – determined for low use areas such as ceiling cavities *
* NB – low use areas are areas that do not have easy access for children and adults and predominantly used for storage. It is important to note that storage of goods in these areas is NOT recommended.
The introduction of this standard has meant that there are some rigid guidelines around the testing procedures and steps which have increased on average the number of sites that are required to be tested. Our samplers will discuss with you what will be required.
At all times we will evaluate the situation based on circumstance and back ground presented for each and every job we undertake. We are committed to delivering a high standard of both sampling services and advice to our clients based on our depth of experience.
