As we have learned, the Catalytic Bead (LEL) sensor can degrade due to "poisoning" and if so, the sensitivity tends to be lost first with regards to Methane. A partially poisoned sensor might still respond accurately to Pentane, while showing a dangerously reduced response to Methane. Some manufacturers offer an "equivalent" mixture of calibration gas (Methane) to address this condition. Contact ... Read More

Gas Detection

Oxygen deficiency is still the leading cause of death in confined space incidents. The concentration of oxygen in normal air is approximately 20.9%. The balance (over 78%) consists primarily of nitrogen. The remaining fraction includes small amounts of water vapor, carbon dioxide and argon, as well as traces of other gases. OSHA 29 CFR 1910.146, "Permit Required Confined Spaces," contains the ... Read More
