The webbing on the harness offers a prime place high up on the shoulder strap to clip a portable detector. Workers who wear fall protection harnesses or high visibility vests actually may find it easiest to wear the monitor. Although some workers may find it uncomfortable to wear on their lapel, if the portable gas detector is not worn near the breathing zone, there’s a chance the device won’t record accurate information about the worker’s exposure. Just as it sounds, the breathing zone is where a person inhales air, including the mouth and nose. That’s why workers should always wear their portable gas detectors in what’s known as the “breathing zone,” such as the lapel, shirt collar, or chest pocket. Safety professionals know that there can be a great difference in gas concentrations between the waist and the nose/mouth area of the workers face. They may wear them on their belt, shoulder or shoe, but none of these locations accurately capture the quality of the air that the person is breathing. Workers tend to have lots of different opinions when it comes to where they should wear their portable gas monitors. Let’s set the record straight and talk about the proper way to wear a portable gas detector. But many workers may not know where portable gas monitors should be worn on the body. The 30 second interval is adjustable.These devices are usually the size of a smartphone and should be clipped onto the person’s clothing. The 3 LED lights will continue to flash once every 30 seconds until the non-compliance condition has been resolved. The instrument flashes it’s 3 LED lights every 30 seconds in the following conditions if the instrument has not been bump tested, or if calibration is due, or if there was a gas alarm event. Safety supervisors will appreciate the non-compliance indicator. H2S and CO are now available in a combo micro sensor. The new O2 sensor is electrochemical with a 3 to 5 year life span. If one filament gets poisoned the second filament takes over. The LEL sensor has a unique design with two active filaments in one sensor to increase it’s resistance to silicone poisoning. The GX-3R represents the latest evolution of gas detection technology utilizing a new generation of micro sensors. It simultaneously monitors and displays LEL combustibles, O2, CO (Hydrogen compensated CO also available), and H2S. The GX-3R is the worlds smallest 4 gas monitor weighing only 3.52 ounces and can comfortably be clipped within a worker’s breathing zone (2.2” W x 2.55” H x 1.02” D). Now there is a 4 gas monitor smaller than many single gas monitors. Traditionally this means only a single gas monitor would be small enough for a worker to practically wear a gas monitor ‘In the breathing zone’. Air sampling filters may be attached to the collar or lapel. 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.
