The work of emergency medical technicians (EMT) during patient evacuation involves lifting task in an emergency situation, which results in the increasing risk of musculoskeletal disorders such as low back pain. The purpose of this research was to investigate the workplace and ergonomic aspect that influence work posture of the EMT using simulation approach in a virtual environment. Biomechanic model (mannequin) of the EMT had been simulated and analyzed by using LBA and OWAS method. The mannequin was given an improvement based on ergonomic principle of manual lifting task and then was reanalyzed. Improvement that can be used for the work system of the evacuation process conducted by EMT considering its nature situation is the work posture of personnel during the process of lifting the patient into the stretcher. The technique that can be used is the proper lifting techniques. The results of this research can be used as a recommendation to the work system of the EMT.
