||Virtual worlds are successfully used for training a personal skill in an emergency situation. In this paper, we present a serious game for fire evacuation training in any public places like office buildings, conventional centers, hotels, and universities. The goal of fire safety evacuation plan is to minimize the damage, i.e. the number of injured people and casualties. In this paper, we built a virtual environment where imitates a classroom building in Bangkok University. We described a design process and development approach for achieving the objectives of evacuation training. The user evaluation was also conducted, showing that the prototype can be used effectively for training a fire drill at other public places.
