in some environments where combustible gas may exist, we use combustible gas alarm to detect combustible gas in the ambient air in the area, so that when the concentration of combustible gas in the air approaches or reaches the explosion pole, the combustible gas alarm will give an alarm in time, warn the area manager or operator to find and eliminate the leakage source of combustible gas, and activate the area exhaust measures to avoid fire accidents. Therefore, we need to regularly check the combustible gas alarm after using it for a long time. Do you know what you should pay attention to when periodically checking Combustible Gas Alarm ? The following is an introduction by Yi Yuntian:

, attention should be paid to the following aspects:

1. use the same gas standard substance as the gas measured by the combustible gas alarm. if the combustible gas alarm does not indicate the gas type measured, isobutane or propane gas standard substance can be used.

2. Before verification, check whether there is flammable gas in the surrounding environment of the combustible gas alarm probe. If it exists, a certain amount of clean air should be filled first, and then the standard sample gas should be continuously introduced to ensure the accuracy of the combustible gas alarm verification. At the same time, it is also necessary to ask whether the enterprise alarm is connected to the solenoid valve linkage, if there is a need to release the linkage in advance, so as not to cause losses to the enterprise.

3. when checking the response time on site, since the detector and alarm controller of combustible gas alarm are generally not in the same area, it is necessary for the checking personnel and the personnel recording the response time to cooperate tacitly, the verification personnel shall notify the recording personnel through the interphone immediately when the standard gas is applied, so as to avoid time difference and affect the recording results. Special attention is that the staff need to use explosion-proof walkie-talkie, so as to avoid explosion.

To sum up, it is some aspects that should be paid attention to when regularly checking combustible gas alarms. Through regular verification of combustible gas alarm, we can better ensure the stability of the use of combustible gas alarm, so as to better ensure the smooth progress of the detection work.
