Do you really choose a gas detector?
1. Determine the type and concentration range of the gas to be detected
The types of gases encountered by each production department are different. Therefore, when choosing a gas detector, all possible situations must be considered, and it is determined what kind of toxic and harmful gases will be produced in the working environment of the laborers, and then choose the corresponding gas detector. Corresponding gas detectors, for example, if workers work in a working environment with carbon monoxide poisonous gas, it is necessary to give priority to choosing an instrument with carbon monoxide detection function, so as to ensure the safety of workers more accurately.
Second, determine the use of gas detectors
Depending on the industrial environment, the types of gas detectors are also different. If you use this type of instrument as a safety alarm in an open place, such as an open workshop, you can use a gas detector that you wear because it can be continuous, real-time, and accurate. It can accurately display the concentration of toxic and harmful gases on site, and provide specific guidance for workers' health and safety. If entering a confined space, such as reaction tanks, storage tanks or containers, sewers or other underground pipes, underground facilities, agricultural closed granaries, railway tank cars, shipping cargo holds, tunnels and other workplaces, inspections must be carried out before personnel enter , and it is necessary to conduct detection outside the confined space, in this case, it is necessary to choose a multi-gas detector with a built-in sampling pump.
In addition, because the gas distribution and gas types in different parts of the confined space are very different, for example, the density of flammable and explosive gases in the general sense is relatively light, and most of them will be distributed in the upper part of the confined space; while carbon monoxide and air The density is similar, and it is generally distributed in the middle of the confined space; heavier gases such as hydrogen sulfide exist in the lower part of the confined space. At the same time, oxygen concentration is also one of the types that must be detected. Therefore, if the volatilization and leakage of organic and toxic gases are considered, a detector that can detect organic gases is also needed. Therefore, a complete gas detector in a confined space should have a pumping function (so that it can be detected without contact and at different locations), a multi-gas detector (to detect dangerous gases distributed in different spaces, including inorganic gases and organic gases), and an oxygen detector. (Prevent hypoxia or oxygen enrichment), only in this way can the absolute safety of the staff entering the confined space be guaranteed.
3. Pay attention to the use environment of the gas detector
When using a gas detector, you must pay attention to the use environment. There are many factors that can affect the detection results of the gas detector, such as changes in humidity and temperature. Changes in temperature affect the amount of oxygen actually present in the atmosphere. If the temperature in the working space fluctuates greatly, the detection results of the gas detector may drift; if the air humidity in the working space increases, the water vapor in the air will drive away the oxygen, which may cause the oxygen reading to drop. The impact will not be noticed immediately, but it will slowly affect the degree of oxygen after several hours and affect the test results. Therefore, when purchasing a gas detector, you can give feedback to the supplier about the use environment, so that it can provide a more suitable use environment.
The use of gas detectors can play a role in detection and early warning, allowing staff to divide the warning range, evacuate and do a good job of corresponding levels of protection (for example: consider wearing chemical protective clothing, etc.), which is very important in the production of industrial enterprises It is the key to prevent accidents and ensure the smooth progress of the safe production of enterprises, and it is also the guarantee of the safety of production personnel and surrounding people. Manufacturers must also pay attention to gas detection. When purchasing gas detectors, they should also pay attention to the 3 points for attention shared above.
