Impact of Personal Protective Equipment Training on Pesticide Safety Practices among Agricultural Workers in Nigeria

Abstract

Pesticide use is an important component of modern agricultural production and helps farmers control insects, weeds, fungi, and other agricultural pests. However, inappropriate handling, mixing, application, storage, and disposal of pesticides may expose agricultural workers to harmful chemicals and increase the risk of acute poisoning, skin and eye irritation, respiratory problems, neurological effects, and other occupational health hazards. Personal protective equipment provides an important barrier against pesticide exposure, but agricultural workers may have inadequate knowledge of appropriate protective equipment, incorrect methods of use, poor maintenance, inconsistent use, and limited access to suitable protective materials. Personal protective equipment training provides an opportunity to improve workers' knowledge and practical skills regarding appropriate selection, correct use, maintenance, storage, and disposal of protective equipment during pesticide-related activities. Against this background, this study investigates the impact of personal protective equipment training on pesticide safety practices among agricultural workers in Nigeria. The study will be anchored on the Health Belief Model, Social Cognitive Theory, and the Hierarchy of Controls Framework. The Health Belief Model explains how agricultural workers' perceptions of their susceptibility to pesticide exposure, perceived severity of pesticide-related health effects, perceived benefits of personal protective equipment, perceived barriers, and cues to action may influence their adoption of pesticide safety practices. Social Cognitive Theory emphasizes observational learning, self-efficacy, behavioural reinforcement, and environmental influences in the development and maintenance of safe pesticide-handling behaviours. The Hierarchy of Controls Framework provides a structured approach to occupational hazard reduction, recognizing personal protective equipment as an important protective measure alongside other controls such as elimination, substitution, engineering controls, and administrative controls. Collectively, these theoretical perspectives provide a suitable framework for explaining how personal protective equipment training may influence pesticide safety practices among agricultural workers in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise agricultural workers involved in pesticide handling, mixing, application, transportation, storage, or disposal in selected farming communities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, agricultural zones, local government areas, farming communities, farms, and eligible agricultural workers. Personal protective equipment training will be assessed using indicators such as exposure to structured training, frequency and duration of training, identification of pesticide hazards, selection of appropriate protective equipment, correct wearing and removal procedures, equipment inspection, cleaning and maintenance, safe storage, replacement of damaged equipment, and appropriate disposal. Pesticide safety practices will be assessed using indicators such as consistent use of appropriate protective clothing, gloves, boots, eye protection, respiratory protection where appropriate, safe pesticide mixing and application, avoidance of eating or drinking during pesticide handling, appropriate handwashing and personal hygiene, safe storage of pesticides, proper disposal of pesticide containers, adherence to label instructions, and prevention of pesticide exposure to family members and other community members. Data will be collected using structured questionnaires, validated pesticide safety knowledge and practice instruments, direct observation checklists, training attendance records, agricultural extension records, and relevant occupational health documents. Descriptive statistics will be used to summarize participants' characteristics, exposure to personal protective equipment training, and pesticide safety practices. Inferential statistical techniques, including chi-square tests, t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of personal protective equipment training on pesticide safety practices. Where a quasi-experimental design is adopted, pesticide safety practice scores before and after the training intervention may be compared to determine changes associated with the programme. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that personal protective equipment training has a significant positive impact on pesticide safety practices among agricultural workers in Nigeria. Agricultural workers who receive structured and practical training are expected to demonstrate increased and more consistent use of appropriate protective equipment, improved pesticide handling and application practices, better personal hygiene after pesticide exposure, and safer storage and disposal practices. Practical demonstrations on selecting, wearing, removing, cleaning, and storing protective equipment may improve workers' confidence and ability to use such equipment correctly. Training may also increase awareness of pesticide exposure risks and encourage workers to follow product safety instructions and avoid behaviours that increase exposure. However, the effectiveness of training may be limited by the high cost of appropriate protective equipment, hot and humid working conditions, discomfort associated with prolonged PPE use, inadequate availability of suitable equipment, low literacy, poor enforcement of pesticide safety regulations, and pressure to complete agricultural activities. The study therefore expects accessible, practical, culturally appropriate, and regularly reinforced personal protective equipment training, combined with improved access to appropriate protective equipment, to contribute significantly to improved pesticide safety practices among agricultural workers in Nigeria. The study is expected to contribute to the literature on personal protective equipment training, pesticide safety practices, occupational health, agricultural workers, pesticide exposure, chemical safety, farm occupational health, injury prevention, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Agriculture and Food Security, Federal Ministry of Labour and Employment, National Agency for Food and Drug Administration and Control, agricultural extension agencies, state ministries of agriculture, farmer associations, agricultural cooperatives, occupational health professionals, pesticide safety organizations, development partners, and policymakers regarding strategies for reducing pesticide-related occupational health risks. The study will also provide evidence-based recommendations for integrating PPE training into agricultural extension programmes, improving access to affordable and appropriate protective equipment, strengthening pesticide safety education, promoting routine supervision and monitoring of pesticide practices, training agricultural extension workers in occupational safety, and strengthening regulatory measures for safe pesticide handling across Nigeria.
