Gas Detector Installation at a Large Shopping Mall Septic Tank
This installation site is the septic tank of a major shopping mall's wastewater treatment facility. With recent surges in confined-space accidents and the Serious Accident Punishment Act, septic tanks have become one of the highest-risk locations.
Septic tanks treat polluted water from toilets and washing. The chemical reactions between contaminated wastewater frequently produce toxic gases, and most are located underground with poor ventilation. Hydrogen sulfide poisoning and gas intoxication accidents commonly occur during septic tank cleaning or inspection access.
Recommended Gas Sensors for Septic Tanks
For cost efficiency: O2 (oxygen) and H2S (hydrogen sulfide) sensors. For comprehensive coverage: add CO (carbon monoxide), LEL (flammable gases), and CO2 (carbon dioxide).
🎯 Portable 5-Gas Detector Used at This Site — WANDI EDW500
For confined-space work at septic tanks, manholes, and wastewater facilities, EDW500 measures all 5 gases (O₂·CO·H₂S·CO₂·LEL) mandated by Korea's OSH Act in one device. IECEx + ATEX dual explosion-proof certification + free DCMS cloud + auto-email reporting automatically satisfies the 3-year data retention requirement.
