The Virtual Reality (VR) training is one of modern simulation tools which has been used to help train up staffs to operate equipment and facilities, as well as handling emergency situations in different industries. This paper discusses the theories supporting the adoption of VR technologies in the laboratories and pros/cons of Virtual Reality Training systems. Virtual reality technologies have been applied to different types of trainings in many industries, such as product design and manufacturing, facilities maintenances and territory teaching purposes. A typical virtual reality system includes four basic elements: 1) Input devices in order to simulate the working behavior; 2) Output devices; such as VR headset to allow the user in the virtual environment; 3) graphical system that produce simulated scenario(s); 4) Database to store the different conditions to simulate the operation environment.
