Installed Gases
Project Details
Under a proposed amendment to the Occupational Safety and Health Standards Regulations, workers performing confined-space work must carry equipment capable of measuring five gases (O2, CO, H2S, combustible gas, and CO2) and managing the recorded data.

Portable confined-space gas detector
The reason for this amendment to the industrial safety and health standards is that, as asphyxiation accidents during confined-space work have recently surged, the revision aims to more clearly define employers' obligations and better protect workers from danger.

EDW500 gas detector
The EDW500 portable multi-gas detector is equipment that fully complies with the industrial safety and health standards.
- Measurement items: oxygen (O2), hydrogen sulfide (H2S), carbon monoxide (CO), carbon dioxide (CO2), combustible gas (EX)
- Data storage: up to 3 years of data storage via the DCMS cloud server
- Safety management: worker location tracking and real-time gas concentration monitoring by a safety observer
- Measurement method: usable in either diffusion mode or pump-suction mode

Gas detector compliant with industrial safety and health standards
The EDW500 portable multi-gas detector has no charge for cloud service use, and up to 10 managers can log in at the same time to check the gas concentration of the work environment in real time.

Monitoring system for confined-space work safety observers to check gas readings
EDW500 multi-gas monitoring development case (1): At a site where internet and mobile signal could not reach, an in-house Wi-Fi network was built so that managers could check gas concentration in real time on a tablet PC.
EDW500 multi-gas monitoring development case (2): Technical support was provided so that real-time gas concentration could also be checked together with the worker's body-cam software.

Confined-space five-gas detector EDW500
For confined-space work such as manholes, wastewater treatment plants, and retention tanks, the EDW500 is a portable gas detector that complies with industrial safety and health standards.


A cloud monitoring service is provided free of charge so that ground-level managers can check the air condition of the workplace in real time.
