CURTIN INDUSTRIAL SAFETY TRIAL - METHODS AND SAFE PRACTICE AND HOUSEKEEPING OUTCOMES

Introduction: Behavior-based safety programs have been well tested und er controlled circumstances but less is published on their effectivene ss in uncontrolled conditions. The aims reported in this paper were to evaluate a behavior-based safety program in terms of effectiveness to improve safe work practices and good housekeeping, and the effect of mode of administration upon program effectiveness. The compliance of c ompanies in implementing the intervention was also investigated. Metho ds: Nine work areas in seven companies were selected in Western Austra lia A quasi-experimental within-group before-after design with a multi ple baseline was employed. The behavior-based safety intervention was based closely upon that described by Komaki, Barwick and Scott, J. App l. Psychol. 63(4) (1978) 434-445. Baseline observations continued for a minimum of four weeks and post-intervention observations for a minim um of ten weeks. Observations were conducted by employees, and feedbac k administered jointly by the company and the researchers. Observer ag reement was monitored throughout. The outcome variables were the safe practice rate and the good housekeeping rate. Results: Three out of ni ne work areas demonstrated a statistically significant improvement in both safe practices and good housekeeping. Three had a significant imp rovement in housekeeping but a nan-significant improvement in safe pra ctices. One was worse in safe practices and improved in housekeeping ( both non-significant). Two were worse in both safe practices and house keeping (not significant). There was no association between programs c oordinated by employees on the floor versus supervisor-coordinated pro grams. Discussion: The behavior-based safety program did not perform a s well in this trial as has been previously documented. Further field trials in uncontrolled industrial conditions are needed to better unde rstand the practical usefulness of behavioral-based safetyprograms. (C ) 1997 Elsevier Science Ltd.
