A Study of Preventive Measures against Mountaineering Incidents Based on Analysis of Main Causes and Background / Indirect Factors of Near Misses or Incidents

Abstract

Mountaineering incidents usually proceed from the interaction of various, sometimes scattered causes or contributory factors sequentially. This study examined the relations between main causes and background / indirect factors in near misses or incidents recognized by Japanese mountaineers. In addition, we examined what situation of incidents and personal attributes were relevant to the main causes. As a result, analyzed data showed variations in the selection between main and background / indirect factors, and several patterns in the relationship between main and indirect factors. Also, the possibility of development in examining sequential linkage of factors was shown. It should be noted that variations among personal attributes affecting the selection of the main causes and among relations to the situations at near miss or incidents occurring.
