The passive fire protection industry is rapidly growing in South Africa.
Further to my promise to do some more research on intumescent paint, Rayno Frederiks from Genesis Blasting & Coating has been kind enough to send me this: The passive fire protection industry is rapidly growing in South Africa.
It includes the application of intumescent paint to structural steel, and over the past number of years, timber. Due to accidental fires, passive fire protection now plays a major role in compartmentalisation, in both commercial and domestic sector of the building industry.
In cases of intumescent applications to timber, the most common requirement is to achieve a Class 0 and Class 1 spread of flame rate, defined by BS476 Part 7. Class 1: Protection of a surface from the spread of flame. Class 0: Protection of a surface from the spread of flame and limiting the amount of heat released from the surface during a fire.
The decision to meet either of the classifications is usually determined by fire consultants, architects and the fire department.
I am still waiting to hear back from other bodies that I contacted but in the interim, George, a reader, has contacted me about a range of products produced in the US he is involved with, all linked to fire retardation and thermal control. I will get together with him and if any are applicable to the domestic market here I will share the information.
