DANSK DS/ISO 16732-1 [ Active ]

This International Standard provides the conceptual basis for fire risk assessment by stating the principles underlying the quantification and interpretation of fire-related risk. These fire risk principles apply to all firerelated phenomena and all end-use configurations, which means these principles can be applied to all types of fire scenarios. This International Standard is designed as a guide for future standards that provide formal procedures for the implementation of the risk assessment principles for specific applications, e.g., situations in which only certain types of fire scenarios are possible. Those future standards will complete the process of full standardization begun by this International Standard, which not only specifies the steps to be followed in fire risk assessment but also provides guidance for use in determining whether the specific approach used for quantification falls within an acceptable range. Principles underlying the quantification of risk are presented in this International Standard in terms of the steps to be taken in conducting a fire risk assessment. These quantification steps are initially placed in the context of the overall management of fire risk and then explained within the context of fire safety engineering, according to ISO/TR 13387. The use of scenarios and the characterization of probability (or the closely related measure of frequency) and consequence are then described as steps in fire risk estimation, leading to the quantification of combined fire risk. Guidance is also provided on the use of the information generated, i.e., on the interpretation of fire risk. Finally, there is guidance on methods of uncertainty analysis, in which the uncertainty associated with the fire risk estimates is estimated and the implications of that uncertainty are interpreted and assessed. This International Standard is not structured to conform with any national regulation or other requirement regarding the use of fire risk assessment or the type of analysis that is to be performed under the name of fire risk assessment.
