How often is the combustible gas alarm checked?
Combustible gas alarm can be divided into industrial combustible gas alarm and household gas alarm according to the use environment. Besides the use environment, it can also be divided according to the detection gas and product form. Industrial combustible gas alarm is mainly used in large factories, petroleum industry, mining industry and other places where there is gas leakage. The installation of alarm is mandatory by the state. The service life of combustible gas alarm is generally about 2-3 years. It is mainly used to detect the concentration of combustible gas in the air, which can effectively ensure the safety of people's lives and property. How often is the combustible gas alarm detected? Do you need regular verification? Now let's take you to have a detailed understanding, hoping to help you.
1. Article 5.5 of Combustible Gas Detection Alarm (JJG 693-2004) stipulates that the verification cycle of combustible gas detection alarm generally does not exceed 1 year. In case of abnormal vibration of the instrument, or doubt about the indicated value, and if it is sufficient to replace the main components, the instrument shall be submitted for inspection in time.
2. Under normal circumstances, it can be detected once a year, because the service life of the combustible gas alarm is about 2-3 years, and the data will drift after a long time. Of course, this also depends on the frequency of use. For example, if the data is floating after half a year of use, it needs to be detected and calibrated.
3. Combustible gas alarms are generally inspected and calibrated every six months or a year, depending on the working environment. The calibration can be conducted by the manufacturer or the local technical supervision bureau.
4. The service life of combustible gas alarm sensor is 2-5 years, which belongs to consumables, so we should ensure that the product can work normally during use. According to Article 2.8.8 of the Code for the Use of Natural Gas Industry in the Contract Law of the People's Republic of China, the used combustible gas alarm should be calibrated at least once a year, so it is legal to detect the combustible gas alarm once a year.
