flameproof regulations

[kmk]

Hi! Wonder if anyone can help me...I get a bit confused when theatres say sets and need to be flameproof as this doesn't seem to always mean you have to use class 1 timber (am I right about this?). Also re canvas - does this also come in different classes of fire retardency? I would be very glad to finally sort this out once and for all! Also, if I do want class 1 timber, do I get this from normal timber merchants? Any names of places in London that do it much appreciated! Thanks a lot in advance!

You can buy fire retardent chemicals from Rosco to treat wood and canvas [I have no connection to them but there products work well enough] there may be cheaper companies if you can find one as Rosco tend to be expensive.You do not need to buy expensive wood for most set work it is a waste, we are in the business of illusion.In theatre all that glitters is usually glitter.

Thanks David,

Does this mean then that if a theatre says all set materials must be flameproof it is sufficient to use these chemicals? I know Flambar. What is class 1 wood then? Cheers

class one timbere is 'straight and free of defects' and using those chemicals makes the sets comply if used in accordance with the directions

Cheers again David!

Um, as far as 'flameproof regulations' go, Class 1 refers to BS 476 Pt 7 (Surface spread of Flame)
