RS Korea — FIX800 Five-Gas Detector and LED Display Installation at Telecom Branch Underground Wastewater Treatment Room (Dongjak-gu, Seoul)

RS Korea completed installation of a FIX800 fixed five-gas detector and FIX-DS LED status board at a telecommunications company branch building in Dongjak-gu, Seoul, continuing the same nationwide rollout program described in an earlier installation at the company's Wonju, Gangwon-do branch. This installation follows the same specification and procedure as the Wonju site, carried out under Article 618 of Korea's Occupational Safety and Health Standards, which requires monitoring of five gases in confined spaces to prevent worker asphyxiation: O2 (oxygen), CO (carbon monoxide), CO2 (carbon dioxide), H2S (hydrogen sulfide), and EX (combustible gas). The Dongjak-gu building is a headquarters-level site, and the client specifically emphasized both confined-space safety for future occupants and installer safety during the work itself. Equipment installed: - FIX800 fixed multi/single-gas detector — configurable with a dual CO/H2S sensor to simultaneously measure all five legally required gases from a single unit. - FIX-DS dedicated monitoring display — a high-visibility LED status board custom-built to match the detector configuration. Site preparation: Before entering the confined space, technicians set up safety signage covering confined-space worker safety training, a site risk assessment, an on-site representative registration, and the client's work permit form. A blower supplied fresh air into the space for 15 minutes prior to entry, after which a portable EDW500 pump-type multi-gas detector was used to verify safe atmospheric conditions before work began. The EDW500 was then left on site for continuous monitoring — a decision explained further below. Installation work: Two teams worked in parallel, one installing the display board and the other the detector, with cable routing mostly following existing trays positioned at a convenient working height. Gas concentration inside the confined space was checked hourly throughout the work. Because the EDW500 unit left on site includes a USIM-based IoT connection, the client was able to monitor real-time gas readings remotely via mobile device — a feature that drew strong client interest, leading RS Korea to submit a follow-up proposal for expanded IoT monitoring after the installation was complete. Completion: Power was supplied to the display board via an outlet behind the mounting column, and both the detector and display board were confirmed to be operating normally. This completes the second of two wastewater treatment room installations at this building. The continued expansion of fixed gas detection installations for worker safety reflects a broader national trend toward stronger safety awareness, and RS Korea continues to adapt its installation methods to match evolving industry standards.
