Impact of LPG Cylinder Safety Education on Safe LPG Handling Practices among Food Vendors in Nigeria

Abstract

The use of liquefied petroleum gas (LPG) for cooking is increasingly common among food vendors in Nigeria because of its efficiency, convenience, and suitability for commercial food preparation. However, improper handling, storage, transportation, installation, or use of LPG cylinders may increase the risk of gas leakage, fire, explosions, burns, and other occupational injuries. Food vendors may be exposed to these hazards because of inadequate safety knowledge, poor cylinder maintenance, improper placement of cylinders, unsafe hose connections, overfilling, and inappropriate responses to suspected gas leaks. LPG cylinder safety education provides an opportunity to improve vendors' knowledge of LPG hazards and promote safe practices in the handling and use of LPG cylinders. Against this background, this study investigates the impact of LPG cylinder safety education on safe LPG handling practices among food vendors in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and Protection Motivation Theory. The Health Belief Model explains how food vendors' perceptions of susceptibility to LPG-related accidents, perceived severity of fire and explosion consequences, perceived benefits of safe LPG handling, perceived barriers, and cues to action may influence safety practices. Social Cognitive Theory emphasizes observational learning, behavioural modelling, self-efficacy, reinforcement, and environmental influences in developing and maintaining safe LPG-handling behaviours. Protection Motivation Theory explains how perceived LPG-related threats, response efficacy, response costs, and confidence in one's ability to prevent or respond appropriately to LPG hazards may influence vendors' motivation to adopt protective practices. Collectively, these theoretical perspectives provide a suitable framework for explaining how LPG cylinder safety education may influence safe LPG handling practices among food vendors in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise food vendors who use LPG cylinders for commercial food preparation in selected markets, roadside food vending areas, restaurants, canteens, and other food-service locations across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, markets, food-vending clusters, and eligible food vendors. LPG cylinder safety education will be assessed using indicators such as exposure to LPG safety education sessions, frequency and duration of education, knowledge of LPG hazards, awareness of appropriate cylinder storage, knowledge of safe cylinder positioning, understanding of proper hose and regulator connections, knowledge of leak detection, awareness of appropriate cylinder inspection and maintenance, knowledge of safe transportation and handling, understanding of appropriate cooking-area ventilation, awareness of cylinder filling and refilling precautions, and knowledge of appropriate actions during suspected gas leakage or fire. Safe LPG handling practices will be assessed using indicators such as appropriate cylinder positioning, keeping cylinders away from direct heat and flames, maintaining adequate ventilation, checking hoses and regulators for damage, detecting and reporting gas leaks, avoiding unsafe cylinder manipulation, keeping combustible materials away from cylinders, using appropriate regulators and hoses, ensuring safe cylinder storage, avoiding smoking or open flames near LPG cylinders, and following appropriate procedures during cylinder replacement or refilling. Data will be collected using structured questionnaires, LPG safety knowledge assessment tools, standardized observation checklists, LPG handling practice instruments, and pre-test and post-test assessments where a quasi-experimental intervention is adopted. Descriptive statistics will be used to summarize vendors' demographic and occupational characteristics, LPG usage patterns, previous safety training, workplace conditions, and safety practices. Inferential statistical techniques, including chi-square tests, paired and independent t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of LPG cylinder safety education on safe LPG handling practices. Where a quasi-experimental design is adopted, safety-practice scores before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that LPG cylinder safety education has a significant positive impact on safe LPG handling practices among food vendors in Nigeria. Vendors exposed to structured and practical LPG safety education are expected to demonstrate greater adherence to appropriate cylinder-handling and storage practices than vendors without comparable exposure. Education may improve vendors' ability to identify LPG hazards, position cylinders safely, inspect hoses and regulators, recognize gas leaks, maintain adequate ventilation, prevent contact between cylinders and heat sources, and respond appropriately to suspected leaks or fire incidents. Practical demonstrations and supervised safety exercises may further strengthen vendors' confidence and ability to apply safe LPG practices. However, inadequate access to functional safety equipment, poor maintenance of LPG facilities, overcrowded vending environments, financial constraints, unsafe refilling practices, limited access to trained technicians, and established unsafe behaviours may reduce the effectiveness of education alone. The study therefore expects regular, practical, accessible, and culturally appropriate LPG cylinder safety education, supported by appropriate safety infrastructure, equipment maintenance, and regulatory enforcement, to contribute significantly to improved safe LPG handling practices among food vendors in Nigeria. The study is expected to contribute to the literature on LPG safety, occupational health and safety, food-vendor safety, fire prevention, gas-cylinder handling, injury prevention, emergency preparedness, environmental health, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, Federal Ministry of Labour and Employment, Nigerian Midstream and Downstream Petroleum Regulatory Authority, Federal Fire Service, state fire services, local government authorities, market associations, food-vendor organizations, occupational health professionals, environmental health officers, public health practitioners, development partners, and policymakers regarding strategies for improving LPG safety. The study will also provide evidence-based recommendations for integrating LPG cylinder safety education into food-vendor training programmes, strengthening practical safety demonstrations, improving access to appropriate LPG safety equipment, promoting regular cylinder and hose inspections, improving ventilation and storage conditions, strengthening emergency-response preparedness, and developing sustainable LPG safety programmes for food vendors across Nigeria.
