This is the second in a series of published documents (PDs) in support of BS 7974 a British Standard providing a framework for developing a rational methodology for designs that protect people, property and the environment from fire. The standard uses an alternative fire safety engineering approach, based on applying scientific and engineering principles. The PDs contain guidance and information on how to
