Install Panic Button precautions
First, the gas alarm manufacturers to remind the toxic Panic Button to be installed in the possible leakage of gas source within 1 meter. The flammable Panic Button in the small explosion-proof area must also be installed within 1 meter of possible leakage source. The proportion of more than 0.975 that is heavier than air combustible gas probe such as liquefied petroleum gas, installed in the ground 0.3 to 1 meter height; the proportion of air than small combustible gas probe such as hydrogen installed in the range of 0.3 to 2 meters from the ceiling.
Second, the explosion-proof combustible Panic Button detection area: a single or multiple combustible gas concentration changes in the response of the detector. Can be divided into point type, linear, gas detector installation spacing, outdoor is installed every 15 meters, that is, the protection radius is 7.5 meters; closed and semi-enclosed indoor space is 7 meters spacing to install a protection radius Is 3.5 meters.
Intrinsically safe probe on the wiring tube sealing no special requirements, flameproof probe to be required to meet the regulatory requirements of the wiring explosion-proof measures, such as the use of explosion-proof junction box and explosion-proof joints, elbow and so on.
Third, the flush Panic Button installation spacing, outdoor is installed every 15 meters, that is, the protection radius is 7.5 meters; closed and semi-enclosed indoor space is 7 meters spacing to install one, that is, the protection radius is 3.5 meters. The toxic Panic Button should be installed within 1 meter of possible leaks. The flammable Panic Button in the small explosion-proof area must also be installed within 1 meter of possible leakage source. The proportion of more than 0.975 that is heavier than air combustible gas probe such as liquefied gas, installed in the ground 0.3 to 1 meter height; the proportion of air than small combustible gas probe such as hydrogen installed in the ceiling from 0.3 to 2 meters range
Combustible Panic Button and toxic Panic Button is mainly for coal, petrochemical, gas transmission and distribution, biochemistry and other industries. For a variety of occasions suitable for what kind of detector, select the professional Panic Button is engaged in every safety work to understand the staff, the following Panic Button manufacturers for how to choose an Panic Button to do a detailed introduction.
In the purchase of Panic Button to pay attention to the type of gas to be detected, toxicity and concentration range, the release of each industry or the use of different gases, select the Panic Button to detect the gas is different in the use of the process, if the main contact Is the methane and other less toxic gas, it is undoubtedly the choice of LEL detector is the most appropriate, not only because the detector works simply, easy to operate, the application is also more extensive, but it also has a maintenance , Calibration and other characteristics, if there is carbon monoxide, chlorine, ammonia and other serious harm to human health toxic gases, we must choose to detect specific gas Panic Button, if there are a variety of toxic or combustible gas, you can choose two, three One, four in one, five in one and so on a variety of Panic Button in order to ensure staff arrangements.
The type of Panic Button is not the same, the fixed Panic Button is generally used in the industrial production process, he can install a specific monitoring point on the specific gas leak detection. Portable Panic Button because of his operation more convenient, small size, can be brought to different production areas, electrochemical detector using alkaline battery-powered, continuous standby 300 hours or so, so the Panic Button in all types of factories and health sector applications More and more widely.
