In this study, the provisions for means of escape in the codes and regulations of several countries are collected, and compared among countries. The concept and the engineering basis of these provisions are discussed for developing performance based standards. In every country, the minimum number of means of escape required is principle two. Single means of escape is allowed if a room or part of floor has not more than fifty occupants. The maximum travel distance varies depending on many factors, such as occupancy, building height and number of different directions of means of escape. The limitation of common path of travel is nearly one half length of the maximum travel distance in many countries. The capacity of means of escape is required based on the occupant load factors, except Japan. Required stairs widths for phased evacuation are in the range of 0.8 -1.2 cm per person.
