Scaffold board treatment should now be done to BS EN 13501-1:2007 (fire classification of construction products and building elements), rather than the old BS 476 classifications. Euroclass test methodologies are more robust in evaluating fire performance as they are based on a measure of heat release, fire growth rate, flame spread, smoke and flaming droplets.
There are then two classes of treatment:
- Euroclass B (old class 0)
- Euroclass C (old class 1)
For almost all situations Euroclass C is recommended for scaffold boards, however, in certain high risk situations (including for offshore use) Euroclass B should be used.
Interestingly, London Underground has its own specification:
- Metronet/London Underground Standard 2-01001-002 Fire Safety Performance of Materials Ref DPM-0735 July 2007.
- Treated material should be colour coded or hot branded to conform to the standard and only approved treaters should be used.
