They argue that accidents are a result of the interaction between environmental dangers,objective hazards that arise from the local environment, and human dangers - subjective perils within human control. To illustrate this, consider an alpine ascent where objective dangers exist in the from of crevasses. High temperatures cause these ice formations to be less stable, resulting in a greater accident potential. This can be reduced by crossing the danger zone at night when temperatures are lowest. The authors propose a ten-step plan for assessing dangers in outdoor education environments (seetable 8.1), although these procedures are not always adhered to due to a
