The Risk of Oxygen Imbalance – Why Monitor

Oxygen levels outside the safe range pose serious threats:

Oxygen deficiency (<19.5% VOL) – Dizziness, rapid breathing, loss of coordination, unconsciousness, death (below 10%)
Normal (~20.9% VOL) – Safe
Oxygen enrichment (>23.5% VOL) – Increased fire and explosion risk; materials ignite easily

Common sources of oxygen hazards:

Confined spaces (tanks, sewers, pipelines) – O₂ displaced by other gases
Inert gas purging (N₂, Ar, CO₂) – reduces oxygen
Chemical reactions – oxidation consumes O₂
Leaks from oxygen cylinders or lines – local enrichment
Fermentation / biological processes – consume O₂, produce CO₂ or methane
Welding and cutting – deplete oxygen in enclosed areas

Field Applications – Where the SG100 Works

The SG100 is used for oxygen monitoring in the following industries and scenarios:

Confined space entry – Tanks, manholes, ductwork (pre entry and continuous monitoring)
Oil & gas refineries – Process areas, storage tanks, pipeline pigging stations
Chemical plants – Reactors, mixing vessels, solvent storage
Wastewater treatment – Digesters, headworks, lift stations
Mining & tunnelling – Underground mines, tunnels, ore passes
Food & beverage – N₂ purged packaging, cold storage, fermentation rooms
Pharmaceutical – Cleanrooms, incubators, biological safety cabinets
Laboratories – Fume hoods, glove boxes, animal housing
Power generation – Boiler rooms, turbine enclosures, coal handling
Marine & shipbuilding – Cargo holds, ballast tanks, engine rooms
