Any gas that is harmful to our health is a toxic gas and we should avoid exposure to such gases. Use of toxic gas detector can aid in the detection since most of these gases are colorless and odorless. Early detection of these gases can save lives of many because precautionary measures are taken immediately and those affected given the medical attention before any serious damage is done to their bodies.
Industrial areas have gas ducts to enhance the flow of gases in the area. Release of harmful gases in to the atmospheric air may happen whenever there are chemical reactions in the gas ducts. The gas ducts are also a common feature in some homes and the presence of toxic gases in these ducts is possible. Carbon (II) monoxide, a gas that has claimed lives of many people, may accumulate due to poor ventilation in homes that make use of charcoal. All these harmful gaseous substances may be detected early in the presence of these gas detectors.
Using detectors doesn't mean you are 100% protected since some structural designs of the ducts or external factors can cause the detector to fail to trigger the precautionary measures it's programmed to. Automatic shutdowns will not happen resulting to dangerous gases getting to working spaces with catastrophic effects. Knowledge on what causes this can prevent that from happening.
Atmospheric air mixes with gases in the ducts reducing their concentration levels. If it dilutes the gas too much then the detectors will not be able to detect it. Highly diluted fluids will just show traces of a substance even if it is more than should be when not diluted. The level of the toxics could be high but only traces of it sensed due to high dilution
To solve the dilution effect problem, the sensitivity of the detectors should be increased such that even the lowest level of the gases is detected. The system should then have different alarm systems for different levels of the harmful substances. This prevents being caught unaware by catastrophes.
Duct stratification poses yet another challenge in detection. The ducts have bends, expansions and contractions. In an area of expansion the speed is low and build up of air increases, in that of contraction speed is very high and no build up of air. Taking levels from the two parts will give different results for that same gas flow.
Turbulence in air movements due to very high velocities may present another detection failure. A detector is meant for streamlined movements may not function in turbulent ones. A modification in the detectors to ensure the air does not hit the sensors directly should be made. This will ensure that the sensors work well in both circumstances.
Plant safety professionals recommend installation of the toxic gas detectors in the main supply duct. The detector will be able to shut off supply fans when installed next to the filters. Installation in this part solves the three challenges mentioned earlier.
