In the real environment, it is not easy to get the effective training or to simulate several hazard situations for safety because of the direct exposure to the hazards of the actual system. But the virtual environment(VE) can help the users to get the effective training or to simulate all kind of possible situations without the exposure to the harzards of the actual system. Therefore, the number of virtual reality(VR) application for safety will be increased dramatically in the future. This paper proposes a category of VR applications and also the steps to develope the VE for emergency management.
