タイトル（英文）

Study on measures for safety rule introduction that promote safety behaviors(Part 3) - A procedure for introducing safety rule in the process of developing corrective actions on an incident and measures for rule management-

概要 （図表や脚注は「報告書全文」に掲載しております）

本研究の目的は，安全行動選択の阻害要因を考慮に入れた安全ルール導入方策を体系化・提案することである。まず，実験参加者40名に，モデルタスクを記述詳細度の異なる複数の安全ルールで実施させた後，安全行動選択に至る心理プロセスを評価する質問紙に回答させることで，記述詳細度が及ぼす影響を調査し，以下を明らかにした。１）詳細度の高い What+When+How記述は必要な場合に限るのが望ましい。２）詳細記述が不要な場合でも，What記述にHow, When等に係る最小限の追記が望ましい。次に，前報まで及び上記で示唆される，安全行動選択の阻害要因及び安全ルール導入方策例が心理プロセスへ及ぼす影響を踏まえて，事象対策立案時の安全ルール導入検討手順（検討のフローと着眼点）を考案した。また，先行研究の知見及び上記手順に基づき，作業者の関与，安全ルール有効性評価，といった安全ルール具体化・展開の支援方法を提案した。

概要 （英文）

The purpose of this study is to systematize measures for safety rule introduction that takes disincentives of a safety behavior into account. At first, in order to investigate an effect of level of rule detail on a psychological process of safety behaviors, 40 subjects were requested to do model tasks with different level of safety rule detail, and to answer the questionnaire about the psychological process. As a result, it was suggested that 1) While "What", "When" & "How" description leads to the confidence towards the result of a safety behavior, it also leads to the supposition of decrease in work efficiency and increase in mental workload, so limiting this type of description is desirable. 2) Because the recognition of efficiency of a safety behavior and the confidence towards its result are weak only by "What" description, addition of "How" or "When" description is desirable. Then, based on the effect of disincentives of a safety behavior and example measures for safety rule introduction on the psychological process suggested by previous studies and above, a procedure for introducing safety rule in the process of developing corrective actions on an incident was devised. This procedure comprises two steps (step1: judging necessity of safety rule introduction, step2: deciding level of rule detail) and each step has viewpoints (i.e. "What", "When" & "How" description should be limited to the safety behaviors with specific characteristics such as low frequency) .Measures for rule management were also suggested based on previous studies and above procedure.
