Identifying and Evaluating Occupational Hazards of Infectious Waste Landfill Workers by the JHA Method

Abstract

Background: In waste management, neglecting and mismanaging harmful biological factors can result in adverse consequences for both organizations and employees. Methods: This study aimed to identify and assess the health and safety risks faced by workers at an infectious waste site using the job hazard analysis (JHA) method. This cross-sectional descriptive study was conducted in 1401 at the waste disposal center "Halgheh Dareh" in Karaj. The JHA method involved dividing the job into tasks, identifying safety and health risks associated with each task, determining the probability and severity of the risks, and finally classifying them using a matrix based on the MIL-STD-882B standard. Control measures were also presented. All calculations were performed using Excel 2010. Results: The results revealed that out of the 20 risks analyzed, 40% were classified as unacceptable risks, 25% as undesirable risks, 30% as acceptable risks but in need of revision, and 5% as minor risks. Conclusion: Through the application of the JHA method, we were able to evaluate and classify health and safety risks according to their level of severity. By implementing control measures such as the use of personal protective equipment, periodic medical examinations, administration of the Hepatitis vaccine, and adherence to safety protocols, it is possible to reduce the risks and prevent the occurrence of occupational diseases and accidents that can lead to harm.
