Quantitative Assessment of Safety Risks among Mining Maintenance Employees in West Africa

Mining maintenance employees in West Africa are exposed to significant occupational safety risks. These risks arise from their regular work with heavy machinery, harsh environmental conditions, and the time-sensitive nature of repair tasks. This study provides a quantitative assessment of safety risks among these workers, using accident statistics and standardized safety performance indicators. Data from industrial mining operations were analyzed to compare accident frequency, severity, and lost workdays between maintenance and operational activities. The results show that maintenance work contributes disproportionately to serious and fatal accidents, especially during corrective repairs. The study confirms that preventive maintenance and structured safety procedures are effective in reducing accident rates. These findings offer quantitative support for risk-based safety management strategies tailored to the mining context in West Africa.
