EU recently has cleared conditions for authorization of wood preservative IPBC.
Germany has proposed not to authorize IPBC for automated dipping, considering the products would effects human health through skin contact with treated wood or contaminated surfaces.
After adapted models for exposure assessment, EU concludes that exposure to IPBC of professional operators is not expected to have unacceptable effects for human health. Products with IPBC should be authorized subject to instructions label restricting the use to fully automated dipping.
The instructions are: product contained IPBC must only be used in fully automated dipping processes where all steps in the treatment and drying process are mechanized, and no manual handling takes place, including when the treated articles are transported through the dip tank to the draining/drying and storage (if not already surface dry before moving to storage). The wooden articles to be treated must be fully secured (e.g. via tension belts or clamping devices) prior to treatment and during the dipping process, and must not be manually handled until after the treated articles are surface dry.
