The legal basis for Korea's 5-gas mandatory measurement is Article 619-2 of the Industrial Safety and Health Standards Rules. The 2017 amendment added CO₂ to the 4-gas requirement, and the December 1, 2024 amendment mandates equipment provision, 3-year record retention, and 119 reporting by safety m...

A 5-gas detector measures the 5 gases legally required for confined space work in Korea (O₂, CO, H₂S, CO₂, LEL). The 2017 OSH Act amendment added CO₂, and the 2024 amendment mandates equipment provision and 3-year data retention. WANDI's EDW500 covers all requirements with 5-gas measurement, IECEx+A...

Every year, accidents recur despite gas detectors being present on site. Through real cases — septic tank chain asphyxiation, nighttime unmanned facility leaks, dry-ice CO₂ incidents — we examine concretely how IoT gas detectors could have prevented these tragedies. In the era of the Serious Acciden...

EC (electrochemical), Pellistor (catalytic bead), and PID (photo-ionization) sensors each have distinct operating principles, strengths, and environments where they should or should not be used. Choosing the wrong sensor type can make accurate measurement impossible. This guide covers the right sens...

Gas sensors do not respond exclusively to their target gas. In environments where multiple gases coexist, cross-sensitivity (interference) can cause readings to be completely different from actual concentrations. In complex gas environments, expert advice on sensor type and interference characterist...

A confined space is defined not by its structure but by its hazards — oxygen deficiency, toxic gases, fire, or explosion risk. Over 2015–2024, 298 workers were injured and 126 died (42.3% fatality rate) in confined space accidents in Korea. Pre-entry gas measurement and strict safety procedures are...
