How is LEL monitoring different from toxic-gas monitoring — and why does the sensor matter

The gases that displace oxygen nitrogen, argon, helium, carbon dioxide, methane are almost all colorless and odorless at the concentrations that matter. A worker in a nitrogen purged tank, a CO2 flooded fermentation cellar, a cryogenic storage room, or a semiconductor process bay can lose consciousness in minutes with no sensory warning. The atmosphere feels normal until cognitive impairment sets in and at that point,
