Safeopedia explains Gas Monitors
Certain tasks and occupations expose workers to hazards related to the buildup of harmful gases and depleted oxygen in enclosed spaces. Gas monitors are required in order to warn workers as to potential gas-related risks prior to entry, and these must be programed in accordance with OSHA guidelines. Specific documentation is required as proof that companies maintain, calibrate and program gas monitors in accordance with OSHA guidelines.
