Hazardous safety conditions and incidents were operationally defined for an assembly division at an automotive plant. The conditions were observed and recorded on two different employee shifts for an 11 week period. The experimental design used had three distinct phases. In the first phase baseline data were recorded on the number of hazardous safety conditions by two safety observers. In the second phase two shift supervisors used the safety checklist to record hazardous safety conditions. In the last phase data were taken but the supervisory safety checklist was not used. The data from all observations were discussed in safety meetings near the end of each shift. Results indicated that the frequency of hazardous safety conditions declined 32% for the morning shift and 21% for the afternoon shift when comparing baseline figures to those recorded during the last phase. The results indicated that the use of a safety checklist in safety meetings may be effective in reducing unsafe working conditions.
