The Effects of Training Intervention on Knowledge Level of Occupational Risk Assessment among Engineering Students in a Public University in Selangor

Abstract

Knowledge on occupational safety is crucial in the engineering field. In addition to reducing workplace risks, solid understanding on the basics of occupational safety and how it corresponds to health in the specific direction of Occupational Safety and Health (OSH) will develop engineers with improved ability to ensure safety and health performance. Current curriculum for engineering requires OSH-specific training to be incorporated in body of knowledge. This study aims to assess the effects of OSH risk assessment training on knowledge level among final year engineering students in a local university in Malaysia. Method: This was a one-group pre-test and post-test quasi experimental design conducted among 70 civil, agricultural and mechanical engineering students in a public university in Malaysia. An OSH risk assessment training module based on Hazard Identification, Risk Assessment and Risk Control (HIRARC) guideline was developed and validated as the intervention tool and a 20-item questionnaire was employed as assessment tool disseminated at pre- and post-test stage to evaluate knowledge level. The intervention was delivered in classroom settings and participants answered a self-administered questionnaire at pre- and post-delivery of the training. Data collected was entered into statistical program and was analysed according to objectives. Results: Majority were males (54%), less than 23 years old (29%) and had cumulative grade of 3.0-3.5 (67%). The average (median ± interquartile range) knowledge scores at pre- and post- test stage were 10 (9-11) to 14 (13-15). There was a significant (p<0.05) increase in knowledge level at the post-test stage. Implications: The HIRARC training module developed has a potential to increase knowledge on risk assessment among engineering students. Knowledge on risk assessment will enable engineers to eliminate hazards in the conceptual or designing phase of engineering work, thus reducing probability of accidents and ill-health from occurring in workplace.
