Care should be taken in selecting the most appropriate scaffold board treatment. There are three types of fire retardant treatments: DI – Dry Interior: these types are not suitable for the treatment of scaffold boards as the salts will leach out over time. HR – Humidity resistant: this treated timber can be used in most interior, semi protected or short term exterior situations. Scaffold Boards fall under this description. (note, …

What defects should I look for in wooden scaffold boards?
To ensure maximum life, scaffold boards must be checked regularly. It should be noted that cross cutting a graded board to a shorter length does not affect the structural integrity or grade of the board and as a result, it will still comply with BS 2482:2009; if the board has been either visually or machine graded it will have been graded along the full length. Any defects (unless outlined below) …
What standards exist for fire treating scaffold boards?
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 …
