10th Edition (Nov 2018) WorkSafe "WES Book" published on-line : Water New Zealand

New 10^th Edition of WES Book

Please note that WorkSafe New Zealand’s 10^th Edition of the Workplace Exposure Standards and Biological Exposure Indices Special Guide was published in November 2018, and has been available on line since that time. The published Workplace Exposure Standards (WES) and Biological Exposure Indices (BEIs) in the 10^th Edition have been in place since the date of publication.

Changes to Exposure Standards

The majority of the recommended values that were proposed in the individual proposal documents were adopted, however some values do differ from those recommended in the proposal documents that were made available on-line to stakeholders during the consultation phase.

(Three substances that were under review in 2018 remain under review - these are nitrogen dioxide (NO₂), hydrogen sulphide (H₂S) and synthetic mineral fibre (SMF).)

The main changes in the 10^th Edition are signalled in the Preface, which is reproduced below for your information:

2019 Consultation

Please also note that WorkSafe will commence a period of consultation for a further 35 substances in 2019. The probable commencement date will be some time in March 2019. Those (and others) who have received this email will be advised at the time of commencement.
