Occupational Safety Climate
Zohar, D. · 1980
別名: Safety Culture (climate operationalisation)
Safety climate is the set of shared perceptions workgroup members hold about how safety is actually prioritised in their workplace — inferred not from written policy but from what management does when safety and production conflict. The construct's central insight is that employees read enacted priorities rather than declared ones, and calibrate their own behaviour to what they observe being rewarded and tolerated. Zohar later distinguished organization-level climate, set by senior policy, from group-level climate, set by the immediate supervisor, and showed the two can diverge sharply within the same company.
Theory that workgroup members hold shared perceptions of how safety is actually prioritized, handled, and valued where they work — by management and by the workgroup itself — and that these shared perceptions predict safety behavior and accident rates beyond formal policies. Climate is measured as perceptions of current practice, not attitudes or self-reported behavior.

歴史的背景
Zohar introduced safety climate in 1980 with a survey of Israeli industrial workers, showing that perceptions of management's safety commitment distinguished plants with different accident records. The construct gained urgency after major industrial disasters in the 1980s, when investigations repeatedly identified organizational rather than technical causes. Zohar and Luria's 2005 multilevel model formalised the organization and group distinction. Safety climate is now among the few organizational constructs with a substantial evidence base linking survey measures to objective injury outcomes.
構成概念
管理者の安全優先・コミットメント・能力
The workgroup's shared perception of whether management genuinely prioritizes safety when it competes with production pressure, is committed to it, and handles it competently (Kines et al., 2011). It reads the collision, not the policy: what management rewards when safety costs something. Low scores contaminate the other dimensions, because workers calibrate to what management actually prioritizes rather than to what it posts.
管理者の安全エンパワーメント
The workgroup's shared perception of whether management empowers and involves workers in safety — consulting the people closest to the risk, trusting their judgment, and backing them when they exercise it (Kines et al., 2011). High empowerment goes with rules that fit the work; low empowerment goes with rules made at a distance and quietly renegotiated on the floor.
管理者の安全に関する公正
The workgroup's shared perception of whether incidents are investigated to find causes rather than culprits, and whether people are treated fairly when they report (Kines et al., 2011). This dimension governs the upward flow of bad news: where justice is perceived as low, incidents do not stop happening — they stop being reported, and the organization loses its early-warning system.
労働者の安全コミットメント
The workgroup's shared perception of its own commitment to safety — whether workers treat safety as their own responsibility, help each other work safely, and take initiative, rather than leaving safety to rules and inspectors (Kines et al., 2011). It is the dimension most shaped by group history and by what the group visibly tolerates.
労働者の安全優先とリスク非受容
The workgroup's shared perception of whether safety outranks getting the job done fast — whether hazards are treated as unacceptable or as a normal cost of the work, and risk-taking as competence (Kines et al., 2011). High scores describe a group that does not accept risk-taking; low scores describe normalized risk, which rarely announces itself.
安全コミュニケーション、学習、同僚の安全能力への信頼
The workgroup's shared perception of whether safety knowledge actually circulates — risks discussed when they appear, help exchanged, lessons drawn from what goes wrong, and co-workers' safety competence taken seriously (Kines et al., 2011). It is the mechanism dimension of the workgroup side: commitment supplies the will, communication turns it into shared practice.
安全システムの有効性への労働者の信頼
The workgroup's shared perception that the safety systems — training, safety representatives, safety rounds, early planning of safety — actually work (Kines et al., 2011). High trust means the systems are used and participated in; low trust means they run as theatre, fully staffed and quietly ignored.

この理論に基づくテスト
実践的応用
Safety climate scores are leading indicators of injury rates, predicting future incidents where accident statistics only record past ones — which is why regulators and insurers in high-hazard industries use them in surveillance. The group-level finding is directly actionable: because supervisors create group climate, supervisor-targeted intervention changes climate faster than policy revision, and controlled studies of supervisory safety communication show reductions in injury rates. Aggregated survey results are also used to identify which units diverge from stated organizational priorities.
測定方法
Measured with self-report Likert perception items aggregated to the workgroup or organization; validity depends on demonstrated within-group agreement, and scores are read as leading indicators against sector benchmarks.
批評と制限事項
There is no agreed dimensional structure: published instruments range from single-factor to nine-factor solutions, which severely limits comparability across studies and industries. Safety climate is conceptually close to safety culture, and the two terms are used interchangeably in much of the applied literature despite denoting different things. Aggregating individual perceptions to a group requires demonstrated within-group agreement that studies often do not report. Predictive validity for injuries, while real, is modest in absolute terms, and injury data themselves are unreliable outcomes because reporting is influenced by the very climate being measured.
