TS Korea — Water & Purification Tanks O₂ / CO₂ Safety

Korean OSH rules require oxygen between roughly 18% and 23.5% vol inside confined tanks. Below 18% hypoxia risk rises quickly; above 23.5% fire risk increases. CO₂ extinguishing systems can also deplete oxygen—plan monitoring accordingly.

This site needed O₂ and CO₂ trending with an external LED summary. Because the sump stays humid, we sampled through an external pump and conditioning train.

Linking the FIX-DS display lets operators read tank atmosphere without opening hatches, while buzzers warn before entry. TS Korea designs similar packages for potable water and WWTP clients.
