Occupational Health Knowledge Among Solid Waste Management Workers in Ibadan, Oyo State

Solid waste management workers are among the most occupationally vulnerable groups in Nigerian urban centers, exposed to biological, chemical, and physical hazards with limited access to formal occupational health protection. This study assessed occupational health knowledge and protective practices among solid waste management workers employed by Ibadan's state waste management authority in Oyo State, South West Nigeria. A descriptive cross-sectional design was used, with 160 workers recruited by systematic random sampling. A structured interviewer-administered questionnaire was the primary data collection instrument, supplemented by direct observation. Results showed that occupational health knowledge was inadequate among 77.5 percent of respondents, particularly regarding biological hazard identification and chemical waste classification. Regular PPE use was reported by only 28.1 percent, and post-exposure prophylaxis awareness was very low at 11.9 percent. Needle stick and sharp object injuries had been experienced by 39.4 percent of workers in the previous year. Gastrointestinal infections and dermatological complaints were the most frequently self-reported occupational health conditions. Lack of formal training, absence of occupational health units within the organization, and inadequate PPE supply were identified as structural barriers. This study recommends pre-service and in-service occupational health training, regular health screenings, and the operationalization of an occupational health unit within Ibadan's waste management authority.
