Gas Alarm Repair Execution Standards

Why Gas Detectors Need to Be Tested:

Due to the catalytic fuel cell sensor used in the alarm, the sensor's sensitivity naturally decreases by 10% to 30% each year under normal operation, with a lifespan of 2 to 5 years. If the alarm sensor's sensitivity drops, and the concentration of the leaked gas reaches the lower explosive limit without timely alarm, an explosion hazard may occur. Therefore, the alarm must be periodically calibrated annually to ensure its performance and accuracy of measurement.

A gas leak detector is a device that detects gas concentrations, with its core component being a gas-sensitive sensor. Installed in locations prone to gas leaks, it triggers an alarm and emits a sound and light signal when the gas concentration in the air exceeds a set threshold. If connected to an alarm host and a receiving center, it can initiate network alarms. It can also automatically activate exhaust fans and close gas pipeline valves, ensuring safety of life and property. In civil safety prevention projects, it is commonly used for household gas leak alarms and is also widely applied in various oil refineries, oil depots, chemical factories, liquefied gas stations, and other places where flammable gas leaks may occur. Faced with the various threats of accidents caused by gas leaks, is there really no comprehensive solution? According to some experts, using gas leak detection is one of the important means to combat the invisible killer of gas. Gas experts point out that gas poisoning incidents, which are caused by large-scale gas leaks or exhaust emissions, are the root cause of gas leak emergencies. If gas leaks can be detected, timely warnings can be obtained. Relevant departments have also concluded, after long-term testing, that the effectiveness of preventing gas poisoning and gas explosion accidents is over 95%.
