scope:

Introduction: This manual consists of a number of different alternative approaches to life safety. Each chapter is a different system independent of the others and is to be used in conjunction with the 1991 edition of NFPA 101, Code for Safe€) to Life in Buildings and Structures.

This edition of NFPA 101M contains alternative approaches that are tied into NFPA 101, Life Safety Code. Each of these systems is recognized by the Life Safety Code in its Appendix A as a method that can be used to assist the authority having jurisdiction in determining equivalent compliance to various chapters of the Code.

For further information on alternative approaches to fire safety see "Systems Concepts for Building Fire safety" Section 1, Chapter 3 of the seventeenth edition of the NFPA Fire Protection Handbook and the SFPE Handbook of Fire Protection Engineering, Section 2 "Hazard Analysis Calculations."
