Application of Proportional Importance Index in Industrial Hazards Identification and Assessment of Safety Measures in the Chemical Industry

The identification of hazards and the creation of a safe working environment is a significant challenge for many industries today. As a result, hazard assessments are carried out in workplaces to detect potentially hazardous events and conditions that may result in workplace accidents. Gap analysis on hazard identification and safety management in the workplace was conducted to highlight the level of incompleteness in recent studies on the subject and the need to fill in the gaps in future studies. This research, which took place in both a petrochemical and an oil refining company in Nigeria, identified industrial hazards and evaluated safety measures in the Nigerian Chemical Industry (CHI). Data was collected using a well-structured questionnaire instrument. The research was conducted among chemical industry technical and management personnel whose day-to-day duties expose them to one or more types of hazards in the industry. The questionnaire was given to 96 technical and management staff at the CHI, with 84 (88%) of them completing and returning it. The study looked at the types of hazards, risk awareness, control measures, and the efficacy of safety risks and risk management programmes in Nigeria’s chemical industry. The data was analysed using the modified Proportional Importance Index (PII) and a four-point Likert scale. The top ranking risks in the chemical industry are loud noise (PII = 3.2; respondents = 92 percent), working at heights (PII = 3.1; respondents = 89 percent), machine and equipment vibration (PII = 3.0; respondents = 87 percent), high voltage areas (PII = 2.9; respondents = 84 percent), and chemical spills (PII = 2.5; respondents = 55 percent). Workers in the industry had a high level of safety hazard awareness (p 0.05, 95 percent Cl.; PII = 3.1-3.5). Chemical Industry Number 1 (CHI-1) improved from 87.90 percent to 98.09 percent, and Chemical Industry Number 2 (CHI-2) improved from 81.53 percent to 95.54 percent in terms of worker understanding of hazard and danger identification and evaluation in the chemical industries. These hazards endanger workers’ safety and should be efficiently managed to keep associated risks as low as reasonably and practically possible (ALARPA).
