1. Introduction Situational awareness is the basis for improving the fire rescue safety and efficiency. According to Endsley [1], situational awareness includes three levels, namely, perception of elements in current situation, comprehension of current situation and projection of future status. Situational awareness is an important factor that can affect the fire rescue safety and efficiency. It refers to being aware of what is happening and what potential threats there might be around you [2,3]. To effectively respond to the outbreak of high-rise fires, firefighters need the first-hand information about the building, including its interior layout, evacuation routes, hazardous chemical storage location, structural properties, and fire rescue facilities. Without such information, entering a building would expose the firefighters to great danger. In general, firefighters mainly rely on two-dimensional (2D) evacuation handbooks and paper-based documents to obtain the information. However, due to the complexity of the building structure, it is difficult for paper-based files to effectively display the relationship between equipment information, personnel information and spatial information. In the US, around five hundred thousand building fires were reported in 2017, causing 3400 deaths and 14,670 injuries [4]. Nearly half of the reported firefighter casualties were due to the lack of sufficient information relating to the fire and building interiors [5]. Therefore, the ability to obtain such information in real-time is essential for firefighters to develop their situational awareness. Nowadays, Building Information Modelling (BIM) has been widely used to house a broad spectrum of data relating to the lifecycle activities of buildings [6]. BIM enables to present the architectural layout of the building in a three-dimensional (3D) form. BIM can also be integrated with other technologies to perceive and present more fire-related information. Most studies have demonstrated that BIM has the potential to support fire information inquiries and evacuation route planning [7-10]. Likewise, Internet of Things (IoT) frameworks supported by various sensor types can reflect a building's status in real-time, and such information can be integrated into BIM to achieve dynamic analysis and visualisation of the fire status [11]. This way, the external and interior environment of buildings can be well understood in advance. To improve the kinetics-related ability for emergency response, firefighters can resort to simulated training such as hose dragging, stairs climbing, high-rise pack tasks and so on [12]. Meanwhile, maintaining spatial orientation is an essential skill for firefighters to implement search, rescue and firefighting securely and efficiently, especially when the environmental visibility is greatly compromised. However, in a confined indoor space, the environmental context sensed by firefighters can vary greatly. In order to improve the rescuers' situational awareness, reality training is important [59]. Nowadays, Virtual Reality (VR) allows the creation of large and complex training environments; hence high-risk training can be conducted in a safe and cost-effective way. Researchers have developed different VR applications to complement the traditional firefighting training experience [13-15]. Despite promising, a loss of real-life experience in VR is still recognised as the main problem that inhibits VR applications from being further utilised by the fire sector [16]. In recent years, Augmented Reality (AR) technology has been rapidly developed. With AR, superimposing virtual clues such as ambient temperature, oxygen concentration, and fire location onto the real environment becomes technically viable, which has the potential to complement the loss of reality in VR. Therefore, it has been studied and tentatively deployed in the training regime [17]. Current studies reveal the implementation of BIM, IoT and VR/AR would be more helpful for the acquisition of first-hand information about building properties and indoor fires, which may improve the safety and efficiency in emergency fire rescue scenarios. However, there is scarce research on integrating these technologies to develop a situation awareness system. BIM, IoT and VR/AR integration for fire safety management is still at an initial stage. Hence, this paper aims to develop a proof-of-concept framework that fulfils three purposes to comprehensively improve first responders' situational awareness, namely, dynamic fire monitoring and alerting, AR-based real-time route navigation, and VR-based fire training. The research scope of this article is primarily focused on the realisation of data exchange between the three modules and preliminary exploration of whether the training system can improve situational awareness of humans in the virtual environment. It is beyond the scope of this article to evaluate the robustness of the system in practical usages. In the next section, this study presents a review of the relevant research in these areas.
