Occupational Safety and Health Issues Affecting Air Traffic Controllers in Kenya

Abstract

Air traffic control (ATC) is central to a safe, efficient, and effective aviation system. It comprises three interdependent components, the human element, namely the air traffic controller (ATCO), operational equipment, both airborne and ground based, and established procedures. These components must function in harmony to prevent collisions and maintain adequate separation between aircraft. Occupational safety and health (OSH) issues in air traffic control (ATC) arise from risks associated with the work environment, work organization, personal factors, and operational procedures. The occupational safety and health act of 2007 requires employers to provide a safe workplace that is free from health risks and supported by adequate welfare arrangements. This study evaluated the occupational safety and health (OSH) issues affecting air traffic controllers (ATCOs) in Kenya and was conducted across seven major manned airports. The research was guided by the Theory of the Risk Management Process as outlined in the International Organization for Standardization (ISO) 31000 principles and guidelines. A quantitative descriptive research design was adopted. From a target population of 172 controllers, a sample of 64 respondents was selected. Data were collected using measurement instruments, structured questionnaires and observation checklists. Statistical analysis was conducted using the Statistical Package for the Social Sciences (SPSS), applying descriptive statistics, Pearson correlation, and chi square tests to examine relationships between workplace factors and health outcomes. The findings established that occupational safety and health (OSH) among air traffic controllers (ATCOs) is significantly influenced by the combined effects of the work environment, work organization, operational procedures, and personal factors. In the work environment, inadequacies in lighting, including glare, equipment serviceability, emergency preparedness infrastructure, and elevated noise levels negatively affected safety, health, and operational efficiency. These conditions contributed to fatigue, stress, and reduced performance. Within work organization, deficiencies in shift scheduling, break allocation, and ergonomic considerations were shown to increase physical strain, reduce alertness, and heighten the likelihood of human error. Headaches were reported by 77.0% of respondents, back pain by 68.8%, and disrupted sleep by 48.4%. A strong positive correlation, r = 0.726, was observed between prolonged sitting and screen time. For operational procedures, although emergency procedures were generally effective, gaps in sensitization and limited controller involvement in procedure design reduced effectiveness in routine operations and increased cognitive workload. Personal factors, including attitude, risk perception, and limited adherence to ergonomic practices such as proper posture and adequate breaks, further influenced health outcomes. Notably, 85.7% of respondents relied on self-medication rather than seeking professional support. Inferential analysis showed statistically significant associations between equipment unserviceability and stress, χ² = 6.24, p < 0.05, stress and help seeking behavior, χ² = 23.3, p < 0.001, and back pain and posture deterioration, χ² = 28.96, p < 0.001. The study concludes that while the occupational safety and health (OSH) challenges affecting air traffic controllers (ATCOs) in Kenya are significant, they are consistent with risks recognized within international aviation safety frameworks. However, gaps remain in implementation, enforcement, and contextual adaptation of these standards. The study therefore recommends improving physical working conditions, optimizing organizational systems, enhancing participatory procedure development, and strengthening individual awareness and training to promote safer, healthier, and more effective air traffic control (ATC) operations.
