C Protection from Fire
Two acceptable solutions for two kinds of building. C/AS1 is for risk group SH: detached houses, townhouses with their own escape routes, small boarding houses and outbuildings. C/AS2 is for every other risk group, from apartments and hotels to offices, schools and car parks. A building with complex features goes to C/VM2, a verification method for a fire engineer, which has no tool here.
