The Effectiveness of occupational injury prevention model in relation to occupational incident rate of informal workers: A case study of Trichogaster pectoralis (Snakeskin gourami) processors, Bang Pla sub-district, Bang Phli district, Samut Prakan province

Abstract

The quasi-experimental research with one group pretest–posttest design aimed to evaluate effectiveness of occupational injury prevention model in relation to occupational incident rate of informal workers -- a case study of Trichogaster pectoralis processors. There were 30 samples included into this study by purposive sampling. The study population was evaluated by general and safety behavior questionnaire, safety behavior observation sheet and incident case record. The intervention model was implemented for four weeks. There were 5 elements including (1) hazard identification, (2) safety education, (3) safety behavior observation, (4) safety motivation, and (5) participation. The evaluation of model was performed by measuring behavior-based safety through behavior observation. The incident rates of injury were recorded before and after the intervention on a weekly basis at five different time points. The data were analyzed by descriptive statistics which includes percentage and mean of general data, incident rates of injury, and behavior-based safety. The differences in incident rates pre- and post-intervention were tested by repeated measures ANOVA. The results indicated that following the model implementation the incident rates of injury tended to significantly decrease (p=0.001) and behaviors-based safety continued to increase every week. It can be concluded that the use occupational injury prevention model among informal workers with stakeholder participation is valuable to guide behavior-based safety practices and help reduce occupational incident rates.
