Equip yourself to confidently assess equivalency or evaluate the adequacy of life safety measures with the latest edition of NFPA 101A, Guide on Alternative Approaches to Life Safety. This essential resource for facility managers, inspectors, and code enforcers is used in conjunction with NFPA 101, Life Safety Code, to support equivalency requests through numerically-based fire safety evaluation systems (FSESs). The mandatory values in each FSES align with the requirements outlined in the 2018 edition of NFPA 101.
