Gas stations need to install explosion-proof combustible gas detectors

It is forbidden to use mobile phones at gas stations. Fixed gas concentration detectors are installed at gas stations to prevent explosions.   

Conditions for gas station explosions:
1. High-density oil and gas
When the oil gun at the gas station is refueling, the high-density oil and gas causes the oil and gas density around the refueling vehicle to rise sharply.
2. Radio frequency sparks
Mobile phones receive and transmit electromagnetic waves. When radio frequency waves circulate between the metal conductors of the mobile phone, radio frequency sparks will be generated when there is rust or poor contact, which will cause explosions at gas stations.

High-density oil and gas generally only appear near vehicles and oil guns that are being refueled. Stay away from vehicles and oil guns that are being refueled, and use mobile phones normally outside the refueling operation area.
In addition to the possibility of electric sparks when using mobile phones, the static electricity generated on our bodies is more dangerous! Static electricity sparks are very likely to directly ignite high-density oil and gas. Therefore, when we refuel, anti-static electricity is more important!

Therefore, for safety, it is necessary to install an explosion-proof combustible gas concentration leak alarm as required:

The main gas in a gas station is hydrocarbon flammable gas, which has a greater specific gravity than air, so the installation height should be 60-80 cm from the ground. Find a suitable location to install it without affecting normal work.
