Timber is often treated with chemicals to preserve it, prevent fungus or insects taking hold, and to prevent staining. These chemicals can be hazardous to both produce and use, and particular care needs to be taken to ensure adequate ventilation of areas where timber is being treated.
We have produced guidance with the EPA and the New Zealand Timber Preservation Council on the safe manufacture and use of timber treatment and preservative chemicals.
Timber preservatives and anti-sapstain chemicals describes the preferred design and layout of treatment plants and practices when using timber preservatives and anti -sapstain chemicals.
While this guidance has not been updated to reflect current work health and safety legislation (the Health and Safety at Work Act 2015 and regulations), it may still contain relevant information and practices to keep workers and others healthy and safe.
Please read this guidance in conjunction with all relevant industry standards that apply to you as a PCBU. This guidance will be progressively reviewed and either updated, replaced with other guidance, or revoked.
