Problem Solving: Are Higher-Order Controls Ignored?

摘要

The two null hypotheses have failed to be rejected. Incident causes, categorized as latent and active failures, identified through incident investigations have not changed over time. Solutions to OSH issues, categorized by the hierarchy of controls, identified through incident investigations also have not changed. The results show that risk-reduction recommendations in incident investigations are shifting slightly to include additional higher-order controls. Perhaps the NIOSH PTD initiative and a focus on ANSI Z10 and the hierarchy of controls are having some effect on problem solving.
