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, for continuous use over 3 years in an exterior environment, the processor should be consulted)
LR – Leach resistant: the treatment is locked within the timber cell by a high temperature curing after-treatment. These treatments are expensive and although suitable for scaffold boards, represent an ‘over specification’ and are impractical.
Currently, there are several third party fire retardant treatments and service providers for scaffold boards available in the UK. Marley Eternit provides a fire retardant scaffold board that delivers a solution to the time constraints and logistical demands of treating your scaffold boards through a third party.
All of these treatments are clear and odourless making it difficult to clearly identify a treated board. It is recommended that additional identification should be added to boards that have received a treatment. This can include painting or branding, and ensures the boards can be identified throughout their lifetime. Marley Eternit brands every fire safe scaffold board identifying the class of treatment as standard practise.
