Role of Warning Signs in Accidents Severity and Accidents Frequency and The Rate of Using Personal Protective Equipment in an Auto-Part Manufacturing Company Download PDF

Accidents and damages have always been an important challenge of factories and work places. The aim of this study is to evaluate the role of warning signs on accidents severity and accident frequency as well as the rate of using personal protective equipment (PPE) in an auto-part manufacturing company. Method This is a cross sectional-intervention study evaluating occupational accidents from one year before interventions to one year after interventions in an auto-part manufacturing company with 296 labors located in Sabzvar. This study uses Pearson correlation test, linear regression and square t-test. Results Accident frequency and accident severity rates were 50.34 and 143.05, respectively prior to interventions. They reduced to 19.4 and 79.59 within 6 months after interventions. In addition, frequency-severity indicator showed a significant decrease from 2.68 to 1.23 while the rate of educated workers’ use of PEEs showed a significant increase (p-value=0.0000). Conclusion Warning signs can reduce accidents in terms of frequency and severity. It should be noted that this effectiveness may change over time and decrease.
