ISC #7: Where to wear a gas detector?

Protective pus, belts and protective shoes? If you ask workers to bring a handheld gas detector, you will have to answer a lot of questions that follow.

There is confusion in the existing view of “detection range.” Detection range is described as the distance at which the meter can detect gas; for example, my gas detector can detect gas at a distance of 10feets.

But in reality, in order to detect the gas, that gas must come into contact with the sensor in the gas detector.

Then you will think “that’s why people equip suction pumps”, but it is actually a logic that still has vulnerabilities. One can imagine the following: The pump of the air suction device with a flow of 250~500ml/min, while an adult needs 30L of air to breathe for 1 minute. Therefore, the pump must have a capacity of 60~120 times to be equivalent to the amount of breathing air of adults. Latching, the gas detector needs to be worn in place around the breathing area. According to OSHA, gas detectors should be measured within a radius of 6~9 inches. The collar, flap or chest pocket is the place that meets the criteria to wear a gas detector, then we can see the bright light in case the environment is too much noise leading to hearing loss of effect.

What about when you’re working in an environment with H2S? Since it is heavier than air, should you wear a gas detector on your body by attaching it to your shoes or belt? This gas can be detected faster, but the likelihood is that the gas detector will fall, become damaged, or you simply will not be able to hear the warning, then the monitoring of the gas becomes a questionable fact. Then your safety will become a risk due to? Wear a gas detector in the breathing area, and correct it whenever you hear someone talk about the “detection range” for a personal gas detector.
