Hydrogen sulfide (H₂S) and ammonia (NH₃) are not just odor nuisances — they cause asphyxiation and explosions. Learn how the FIX800 fixed gas detector monitors these gases 24/7 in wastewater plants, septic tanks, livestock farms and cold storage to solve odor complaints and prevent accidents.

Korean OSH exposure limits set NH₃ at TWA 25 ppm / STEL 35 ppm; 300 ppm is IDLH; 15–28 %vol is explosive. The 2012 Gwangju cold-storage NH₃ explosion killed 2 and injured 10; the 2014 Binggrae plant killed 1. WANDI EDW500 portable 5-gas detector — with ATEX/IECEx dual explosion-proof certification,...

Oxygen below 18% vol is legally defined as "oxygen deficiency" in Korea; below 6% causes immediate death. From 2015–2022, 52 workers died in septic tanks and wastewater facilities (KOSHA). The WANDI FIX800 fixed O₂ detector uses an electrochemical sensor (0–30 %vol) to monitor 24/7 and pairs with th...

CO₂ is colorless and odorless — undetectable by human senses. The 2021 Geumcheon-gu accident in Seoul killed 3 and injured 18. WANDI FIX800 fixed CO₂ detector uses an NDIR sensor for 24/7 monitoring, two-stage alarms, and integration with display boards, ventilation fans, and suppression-system inte...

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...

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...
