Effect of Training Interventions on the Reduction of Unsafe Behaviors Using Deming Model

Abstract

Training interventions are regarded as essential managerial strategies in various organizations. The present study investigated managerial interventions in training based on Deming model and their effectiveness to decrease the rate of unsafe behaviors of workers. It was a case study, conducted in a rolling industry and a descriptive- analytic research, done periodically during three years (2012-2015). It was tried to implement training programs based on the Deming cycle. To study the effectiveness of training interventions, safety performance indicators and standardized questionnaires were used. A comparison was also drawn between the rate of unsafe behaviors before and a year after applying the interventions. Sampling safety behavior was used to determine the rate of unsafe behaviors and such behaviors were investigated through checklists and random observations. The mean score of unsafe behaviors was 46%. The most and the least frequently occurred unsafe behaviors were failure to use earmuffs (14.5%) and throwing tools (0.02%) respectively. The results showed that applying interventions were influential in decreasing unsafe behaviors (31%, P=0.006). After interventions, obtained results of safety performance indicators and the status of training came to a desirable level. Findings also proved that training is one of the major cornerstones of improved safe behaviors. Therefore, it is important to hold regular training courses and establish an efficient training system in the workplace to develop safety purposes and professional health.
