Code of Practice for Exempt Laboratories 2007

Under the Hazardous Substances and New Organisms Act (HSNO), teaching and research laboratories may be exempted from certain parts of the Act, provided the laboratories meet the requirements of the Exempt Laboratories Regulations 2001.One means of complying with these regulations is to conform to an Approved Code of Practice.

A Code of Practice for schools has been developed by NZASE and approved by ERMA NZ. 10 January 2007 If schools do not follow this code, school managers should ensure they comply with The Health and Safety at Work (Hazardous Substances) Regulations 2017.

Hazardous Substances Regulations 2017

STANZ has been working with the Ministry of Education, WorkSafe, NZASE and a number of other interested parties on the issue of the Hazardous Substances Regulations 2017.

We have secured a continuance for our Code of Practice for School Exempt Laboratories.  However, due to changes in the new Hazardous Substances Regulations linked to the new Health and Safety at Work Act 2015, schools are no longer be able to use adherence to the CoP as a legal defence in the event that an incident occurs. Under HSWA 2015 EVERYONE in a workplace is considered to be responsible for health and safety not just the PCBU (employer) and must take all practicable steps to prevent an incident from occurring. Other than that the new regulations are pretty similar to HSNO.

This continuance means that you can continue to use the CoP (and the guide to the CoP) as a guide of best practice for hazardous substance management.

NZASE in conjunction with the Ministry of Education and WorkSafe are working on a new Safety and Science document that will replace the Code of Practice, Guide to the Code of Practice and the Safety and Science: A guidance manual for New Zealand schools. This document will cover the Health and Safety at Work Act 2015 and the Health and Safety at Work (Hazardous Substances) Regulations 2017. A release date has not been announced for this document yet.

We will  be keeping you updated as things change.
