according to relevant statistics, by 2022, the number of gas stations in China has reached 119000. In view of the dangerous characteristics of flammable and explosive oil products, gas stations are also listed as hazardous chemical business units with storage facilities. If oil leakage occurs during oil unloading, refueling and other operations, it is very easy to cause fire and explosion. Dangerous accident. Therefore, in order to further improve the risk prevention and control capabilities of flammable and explosive places and strengthen the safety management of gas stations, the Emergency Management Department approved the release of AQ. 3010-2022 "Safety Code for Gas Station Operations" is scheduled to come into effect on April 1, 2023.

the new" gas station operation safety specification, unloading operations, metering operations to expand the safety requirements, and modify and adjust the old specifications previously implemented, such as changing the requirements for standing time before unloading oil, increasing the requirements for self-service refueling operations, changing the management requirements for safety signs, etc. In addition, in light of the increasingly prominent demand for mobile payment in the new era, the new specification deletes the relevant provisions of "mobile communication equipment should not be used in gas stations", increases the security requirements for mobile phone scanning code payment, and allows mobile phone payment under the condition of setting combustible gas sound and light alarm device.Specifically, it includes:

The refueling operation area with combustible gas sound and light alarm device can allow customers to use mobile phones to pay. When the on-site alarm gives an alarm, customers should immediately stop using mobile phones and refueling related operations, and carry out emergency treatment according to the emergency plan. Combustible gas detection alarm design shall comply with GB/T provisions of the 50493.

and yiyuntian, as a high-tech enterprise dedicated to the development and production of professional gas detection equipment, can provide customers with a combustible gas acousto-optic alarm device-MIC-500S-Ex-A fixed combustible gas alarm (oil and gas measurement) .

MIC-500S-Ex-A fixed combustible gas alarm is applied to combustible gas concentration detection and combustible gas concentration exceeding alarm. It can accurately detect combustible gas concentration and display combustible gas real-time concentration value, exceeding sound and light alarm and standard signal output on site, with stable signal, the advantages of high sensitivity and high precision, flameproof connection mode is suitable for all kinds of dangerous places.

fixed combustible gas alarm features:

1, explosion-proof, lightning protection, anti-static, anti-reverse connection design, anti-EMI, EMC electromagnetic interference, anti-pulse surge current impact.

2, conform to the latest national standard and obtain CMC measuring instrument production license, explosion-proof certification and other qualifications.

3, 3-wire or 4-wire 4-20mA standard signal output, HART, voltage output, 2 sets of relay switching values.

4, with standard bus RS485 output (RTU format), on-site sound and light alarm.

5. Optional wired transmission, LAN, Internet, wireless transmission (2km, 5km, unlimited distance).

6. The wireless transmission mode can be 433, GPRS, WIFI or other modes.

7. The standard infrared remote controller can be operated without opening the cover in dangerous situations. The remote control distance is 15 meters, which is simple and practical.

8. It can communicate with the computer, monitor the concentration of the field probe in real time through the upper computer, and store, analyze and print the data on the computer.

9. Each unit can switch to each other, automatically track the zero point to prevent drift, and perform multi-level calibration. Support OEM or ODM customization service.

Safety control is very important in hazardous chemical business units or workplaces such as gas stations. Doing a good job in gas monitoring and risk monitoring can move the safety production supervision work forward, build a solid safety barrier, do a good job in source prevention, reduce the frequency of dangerous accidents, and improve the level of comprehensive safety management.Therefore, in the gas station, we can better ensure safety by installing MIC-500S-Ex-A fixed combustible gas alarm (measuring oil and gas).
