A metaverse-based safety service platform was implemented to be used for RTO facility maintenance. In order to quickly cope with the failure of RTO devices, a safety response and education system is implemented so that it can respond remotely without going to the site through metaverse virtual space technology. Education and training are conducted by creating the same environment as the field with a virtual space and creating various situations. It provides a more intuitive and visually recognizable monitoring environment by combining the monitoring of major equipment currently operating with a 2D screen and the 3D space.
As tools for remote 3D meetings and collaborations, various digital virtual space service technologies have been developed, including virtual offices (VRaum Meet), VRaum Event that can hold conferences or exhibitions, and VRaum Factory that can remotely collaborate with field staff in the same space. The VRaum Meet, where people can meet and meet in a virtual space about RTO devices, is a necessary tool for meetings, allowing for screen sharing, data sharing, whiteboards, memos, as well as remote 3D virtual space meetings that provide remote PCs and multiple virtual spaces.

Visualization
As real-time data collection of field operations becomes possible, various artificial intelligence machine learning techniques can be applied to preserve the system's prediction. A prediction algorithm may be applied using the acquired data based on Table 1.

Figure 11 provides intuitive information for workers through 3D visualization of digital twin-based RTO devices. Through Figure 10, an AR maker is attached to each part, which is expanded to the RTO entire device.Figure 12. RTO equipment manual and monitoring information.
And The data obtained from the sensor are data generated by physical sensors such as temperature, flow rate, and pressure of the RTO. By combining them, the concept of virtual sensors is applied to software calculate new indicator values such as the status of RTO emissions.

Figure 6 shows the service technology that constitutes the platform. Based on actual equipment design data, we model a 3D space that generates mesh and texture for the graphics of equipment. Building a platform for multiple users is based on a dedicated server, and one to four people can access the same virtual space at the same time. Location data and interaction between users are shared according to each user's movement.

As tools for remote 3D meetings and collaborations,
Various digital virtual space service technologies are being developed, such as virtual offices (VRaum Meet), VRaum events that allow conferences or exhibitions, and the VRaum Factory that can remotely collaborate with field staff in the same space. The VRaum Meet, where people can meet and meet in a virtual space for RTO devices, enables remote 3D virtual space meetings that provide screen sharing, data sharing, whiteboards, memos, as well as remote PCs and multiple virtual spaces for meetings. Figure 5 shows examples of VRaum Meet, VRaum events, and the VRaum Factory.
3D Virtual Space Configuration technology reconstructs low-latency, high-quality data on-site through 3D virtual spaces in remote locations. It provides a multi-user-based XR device, PC and smartphone to identify user locations and movements and share remote user locations with sites based on AR glasses (smartphones).

RTO Monitoring
Figure 3 shows the connection between the production facility and the RTO equipment, and the circle number in the RTO device is a picture of the sensor IoT attached to the location to be managed. Edge IoT can provide information to field managers, and the detected data can be connected to a server to be analyzed. For continuous monitoring, measurement data is transmitted remotely by connecting a sensor to the programmable logic controller (PLC) device of the RTO device.

In the event of a failure due to 24-hour operation on weekdays, there are difficulties such as the exact location of the accident at the site, the treatment of VOC harmful substances, and immediate technical support services due to distance. In particular, if a complex equipment usage manual is immature, a lack of handover due to frequent turnover of field personnel, or a problem with factory operation occurs when it is located at a wide and long distance,

For continuous monitoring, measurement data is transmitted remotely by connecting a sensor to the programmable logic controller (PLC) device of the RTO device[5].

Globally, environmental-related equipment is strengthening management of the sources of volatile organic compounds that cause high concentrations of fine dust and ozone. Chemical plants, metal surface treatment, automobile painting, and printing plants are often open 24 hours a day. Among the volatile organic compounds (VOCs) released into the atmosphere from factories, aromatic hydrocarbons such as benzene, toluene, and xylene are powerful carcinogens that cause leukemia, central nervous system disorders, and chromosomal abnormalities, and hydrochloride causes ozone layer destruction and global warming.
The purpose of this paper
implement the metaverse-based safe operation service technology for the maintenance and safe operation of the Regulatory Thermal Oxidation (RTO), an air pollution reduction device. In particular, RTO devices that operate 24 hours a day have limitations in the immediate response when a failure occurs, and equipment installed overseas has inefficient maintenance situations due to problems such as physical distance. To overcome this, digital twin-based space and safety service technology are implemented by converting virtual space into a metaverse. The structure, design, configuration, and assembly manual of parts are implemented in 3D with digital twin parts.

In this paper,
a metaverse-based safety operation service platform is implemented for safe maintenance and operation of RTO devices. Most RTO systems operating 24 hours a day have limitations in responding immediately to a failure over a long distance, resulting in inefficient maintenance situations. In particular, the aging of field personnel, inexperience in equipment operation, and lack of transition due to the turnover of professional personnel cause many problems in equipment operation. Therefore, long-distance monitoring and safety training are required.
A virtual space is constructed based on the metaverse, and the equipment structure, circuit diagram, part characteristics, and detailed configuration are constructed in a 3D shape using digital twin technology. To this end, 3D modeling technology generates a mesh based on the design data of the RTO equipment and generates the texture of the equipment based on the actual picture
