The purpose of a gas monitor is to protect the life and safety of the workers and the facility. A gas monitor only detects gas at the location of the sensors and therefore it is critical that the gas monitor be worn in the correct location to protect the worker and to ensure the most accurate readings.

For the best results, a gas monitor should be worn close to a worker’s breathing zone. So often, they are worn on the waist or clipped on a hard hat. While comfortable, the readings on the gas monitor represent the exposures on your waist, not what the employee is breathing into his/her lungs.

What is the breathing zone?

OSHA defines the breathing zone as a ten-inch radius around the worker's nose and mouth and requires that worker exposure monitoring air samples be collected in the breathing zone. Air sampling devices may be attached to the collar or lapel.
