Identification Of Health, Safety, and Environment Aspects In Cement Factory Using AHP And FMEA Techniques

Cement production processes are associated with different hazards, such as health and safety hazards and environmental pollution. The current study was conducted to evaluate and determine the safety, health, and environmental risks of using FMEA and AHP techniques in the cement factories while providing certain suggestions for controlling them.

The study was conducted as a case in one cement factory in 2019. The checklists for FMEA and AHP techniques were filled out by the evaluation team. The risks were identified and prioritized. Controlled approaches were suggested for the identified risks.

In this study, 101 risk cases were evaluated and categorized in various units of the factory, such as manufacturing and service units. The results of FMEA technique showed that crushing, crushing monitoring, milling, filtration, and pre-heater sections had the highest degree of health and safety risks. The results of AHP technique also showed that the environmental pollution caused by the removal of electro filter from the circuit, electro fan burning caused by over current, the failure of the equipment and process, and the defect in the filtration system were all prioritized.

Through taking technical-engineering measures, adopting comprehensive HSE management solutions, such as changes in the work process, making replacements in parts and used machinery, installing recyclable systems, repairing and maintaining the system of air pollution protection, installing a warning and responsive system, mechanizing activities, shielding, implementing instructions and regular curriculum can greatly reduce the risk level.
