Occupational Injuries and use of Personal Protective Equipment among Casual Municipal Solid Waste Workers in the Informal Sector in Kampala: A Cross-Sectional Study.
Occupational injuries in informal waste workers.
Keywords:Occupational injuries, Occupational risk, Municipal Solid waste
The risk of occupational injuries in municipal solid waste workers in most low- and middle-income countries is increasing. This study sought to determine the use of PPE and its association with injuries among casual waste workers in a prototypical city.
This was a cross-sectional study of casual waste workers at a large city landfill site in Kampala, Uganda. Structured questionnaires were used to obtain data on PPE use and occupational injuries within one year before the study. Multivariate logistic regression was used to determine the relationship between PPE use and occupational injury.
The study was conducted between May 2020 and December 2020 and enrolled 81 participants, 44 (54%) of whom were male. Overall, 27 (33%) reported not using PPE, while 53 (65%) reported experiencing injuries. In the multivariable logistic regression model, the use of PPE was associated with lower odds of injury (odds ratio [OR] 0.09, 95% 95% confidence interval [95% CI], 0.01–0.57; P=0.011). In contrast, perceived risk was associated with a greater risk of injury (OR 34.95; 95% CI, 7.00, 174.56; P<0.001). Prior training on PPE use (adjusted odds ratio, AOR 44.69; 95% CI 6.12–342.02; P=0.002), and older age (AOR 1.16; 95% CI 1.03–1.31; P=0.014), were associated with higher odds of PPE use. Additionally, waste pickers and sorters were more likely to use PPE than site traders.
Among casual waste workers, there was suboptimal use of PPE and a high rate of occupational injuries. This study suggests that the non-use of PPE may be due to a lack of access and training.
We recommend surveillance of injuries among workers in the waste management sector as well as regular training in routine and proper use of PPEs.
