Undesired safety conditions were operationally defined for a large retail drug store. The recording of unsafe conditions were conducted for two different employee shifts for ten weeks. A multiple baseline design (ABC-ACB) was used in which three conditions were introduced: (a) baseline, (b) public posting of a safety performance chart, and (c) individual employee inspections. Results indicated that the frequency of safety hazards declined 23% from baseline for the public post-condition and declined 44% for the employee inspection condition (averaged across both shifts). An advanced analysis of variance indicated significant mean differences (p < .01) between baseline and employee inspection for both shifts. An additional measure was taken correlating photograph ratings by employees on a safety dimension and an attractiveness dimension. The coefficient of correlation was statistically significant (r = .76; p <.05). The results indicate that a training program involving employee inspections may be an effective way of reducing undesirable safety conditions.
