STANDARD OF FIRE ZONE AND SEMI- FIRE ZONE BASED ON CITY FIRE PREVENTION PERFORMANCE EVALUATION IN ASAHIKAWA CITY, HOKKAIDO

Abstract

The first specifications for fire zones in Asahikawa City, Hokkaido, were laid down fifty years ago; since then, the city has undergone considerable expansion. Because of changes in the requirements related to urban structures and buildings, the fire zone specifications have changed considerably in comparison with the initial specifications. Consequently, it has become very difficult to assign accurate fire hazard ratings for fire zones and semi-fire zones in urban areas. To overcome this problem, it is necessary to adopt an objectively specified standard. In this study, we evaluated the fire prevention performance of Asahikawa City by using CVF, aiming at a specified review in fire prevention and a semi-fire zone and settled on a specified standard of a fire zone and a semi-fire zone based on the evaluation result.
