In the media, brominated flame retardants are considered as very dangerous, often in terms such as PBB and PBDE, but boric acid is also listed on the REACH list as a hazardous substance. Woodsafe Timber Protection use two different fire retardants produced by Koppers Performance Chemicals Inc., USA, and Hoover Inc., USA.
- Koppers FirePRO® contains no brominated compounds, but contains a small amount of boric acid in the finished product. The threshold for labelling requirements and restrictions is 5.5 percent by weight of boric acid. This limit is not exceeded and thus Woodsafe FirePRO™-treated wood and plywood does not require labelling. The product is approved by an approval certificate in accordance with the issue requirements for indoor environments.
- Koppers/Hoover Fire-X® contain no brominated compounds or boric acid.
None of Woodsafe's treated wood products are subject to restrictions for downstream users, other than recommendations such as AMV and our product fact sheets. Disposal is performed according to the principle of sorting waste wood as combustible timber. Burning the wood yourself is not recommended due to deteriorated combustion characteristics, which can damage small biomass boilers (e.g. a coke coating may be formed).
