analysis of Parameter related to electrocution accidents based on evaluation of electrical safety performance in small-scale industries

Electrocutions have a low frequency and severe consequences. The purpose of this study was to analyze the parameters related to electrical accidents, and evaluation of electrical safety performance of small-scale industries.

This study was conducted in 2019 on 232 small-scale industries. Electrical accidents over a 7-year period were studied. The tools used included electrical accident report forms and a researcher-made checklist for evaluating the study industries based on electrical safety. Data were analyzed using Chi-square, Fisher and regression tests.

The incidence of electrocution in 125 small-scale industries without safety measures was approximately 10 times that of 107 industries have safety measures. poor housekeeping in the first and second groups was 79.5% and 75.0%, respectively. Perceptual error had the most role in the incidence of electrocution in the two study groups (64.1% and 50.0%, respectively). the rate of personal protective equipment training in the two groups was 3.2% and 44.0%, respectively. the rate of using these PPE in both groups was 5.6% and 55.1%, respectively. In addition, there was a significant difference between the two groups in terms of safety measures (P<0.05). the results of modeling the parameters affecting electrocution showed that electrical safety training had the highest correlation with other variables.

However, it has been found that electrical safety was poor in small-scale industries, so it is recommended to use practical electrical safety training as well as implementing safety systems such as earthing system and circuit breaker switches to help reduction of electrocution accidents.
