High-profile accidents in the Chemical sector across research and manufacturing scaleshave provided strong drivers to develop a new benchmark in safety training and compliance. Herein, we describe the design, implementation, and standardized psychological evaluation of virtual reality (VR) applied to process safety training. Through a specific industrial case study, we show that testable learning of complex safetyspecific tasks in VR is statistically equivalent to traditional slidebased video training. However, VR training presents a measurable positive improvement on trainees' perception of overall learning and their feeling of presence in the task during training. It has also been shown that knowledge retention from video lectures can be overestimated, if not controlled. Through these resultsand our transferable blueprint for robustly assessing any new VR training platformwe envisage a range of technologically enabled efforts to enhance safety performance in both laboratory-and plant-based activities. Implications for physical resource-saving projects are also described.

“…It needs to be asserted that the commercially available computational fluid dynamics code FLUENT has been employed so far in several accident scenarios [7], [6], [8], [9], [10]. Simulation in this research shows the effects of the temperature with wind velocity on the dispersion of chlorine gas in the indoor environments that include a chlorine tank in the storage.…”

Most of the industrial chemical products encounter natural environmental risk in the process. The indoor release of hazardous dense gases is especial topic for discussion nowadays because the clouds of heavier gases have a tendency to stay near the ground level, causing fatal and injuries the people. In this article a computational fluid dynamics (CFD) code FLUENT was employed in order to model the accidental indoor dispersion of chlorine from a small undetected leak in an indoor industrial space. The results of simulation represented that the chlorine gas spread would behave like liquid and flows on the floor, also the concentration of chlorine increased to above the ground level slowly. The effects of various temperatures and wind velocities on dispersion of heavier gas will help to better identify the potential risks. In this paper, the effects of the environmental situations with the release and spread of chlorine in the indoor space were meticulously examined.

“…In terms of software engineering, most of the software programs are designed for mine fire simulation, of which the representative ones include MFIRE, POZAR, uQEM, CFIRE, and MFRDSS, developed by the scientific research institutes from the United States, Poland, Australia, and China [6][7][8][9]. Currently, the software programs of fire simulation are mainly reflected on the differential equation method and the time interval method [10], where the former obtains the arithmetic solution by establishing the differential equations and the finite difference method, while the latter carries out the solution by adopting the "Hattie-Claus Method" or "Newton Method" [11,12] and using the virtual simulation technology [13,14] and 3D technology [15,16] to describe the fire propagation process. Nevertheless, few studies have been conducted on the macroscopic ventilation dynamic system, the wind turbulence situation, the gas explosion disaster field, and the spatiotemporal evolution relationship of the gas explosion process caused by a gas explosion; in particular, there is a lack in the analysis of the 3D mine gas explosion disaster simulation and the development of visualization simulation software.…”

To truly represent the developing changes and spatiotemporal effects of gas explosion in underground mine, this paper discussed the field modeling and visual simulation technology of mine gas explosion. Through analyzing the characteristics of various field parameters, space geometric field models, physical attribute field models, and meteorological parameter field models were established to describe mine engineering, ventilation network, and explosion disaster process, respectively. Based on the generated model class and simulation timing flow of gas explosion disaster field, OpenGL technology was adopted to visualize the model of gas explosion disaster field, which simulated the overpressure propagation process of gas explosion shockwave and dynamic spread process of disaster gas, thereby to reveal the developing changes of gas explosion parameters in time and space. Taking the gas explosion accident that occurred in a certain mine in China as an example, the disaster process was inferred to examine the availability of the mine gas explosion disaster field model. The research achievements in the paper not only embody the great engineering value of visual simulation technology in the field of safety engineering but also provide references for accident impact prediction, assessment, and emergency plan.
