Abstract

Occupational illnesses and injuries are the partly result of unsafe work practices. Safety training, an occupational health and safety standard, could either reduce or prevent such illnesses and injuries. This quasi-experimental research aimed to examine the effect of integrated safety training on safety work practices among 54 waste collectors working in Su-ngai Kolok and Muang districts in Narathiwat Province. The workers were equally divided into an experimental or a control group (27 in each). The study was implemented during September to November 2021. The research instruments consisted of 1) an integrated safety promotion program on safety work practices which was developed based on the literature review, and 2) a questionnaire on safe working practices among waste collectors modified from a safety work behaviors questionnaire by Sitthichai Jaikhan et al. (2019). The content validity of the questionnaire was confirmed by experts with a content validity index of 0.97 while reliability was at an acceptable level (0.86 - 0.90). Data were analyzed using descriptive statistics and t-test. The findings showed that after receiving the integrated safety promotion program on safety work practices, the mean scores for safety work practices among the experimental group (x ̅ = 73.89, S.D.=1.12) were significantly higher than those of the control group (x ̅ = 47.93, S.D.= 2.45) (p<.001). Furthermore, it was found that the mean score for safety work practices among the experimental group after receiving the integrated safety promotion program (x ̅ = 73.89, S.D.= 2.45) was significantly higher than that before receiving the program (x ̅ = 47.85, S.D.= 2.16) (p<.001). These findings indicate that occupational health nurses and related staff should place great concern on the application of integrated safety promotion programs into their own work. This is anticipated to enhance safety work behaviors, thereby, reducing occupational illnesses and injuries, as well as enhancing the quality of working life among waste collectors.
