Be ready to assess safety levels and establish equivalencies with assurance. Alternative approaches to life safety are described in NFPA 101A, Guide on Alternative Approaches to Life Safety. The procedures in this guide can be utilized to help determine equivalency when used as part of the technical documentation presented to the authority having jurisdiction. This guide is crucial for facility managers, inspectors, and code enforcers. The purpose of NFPA 101A is to support equivalence requests using numerically based fire safety evaluation systems (FSESs) in conjunction with NFPA 101, Life Safety Code. A system is presented for a distinct occupancy in each chapter. Health care, residential board and care, correctional and imprisonment, business, and education are among the occupations covered.
