You must have often seen that while filling gas in a CNG car, passengers are disembarked. Whereas when petrol or diesel cars are taken to the petrol pump, the passengers sit comfortably. Why is there so much difference in filling of petrol, diesel and CNG fuel? And know further about what kind of dangers there are regarding CNG cars.
In fact, if proper precautions are not taken at the right time regarding CNG cars, there is a risk of it exploding. Often there is a warning written on the petrol pump that passengers should be disembarked before filling CNG. There is a security issue behind this.
What kind of danger is there from CNG?
CNG (Compressed Natural Gas) gas is stored under high pressure. If any leakage occurs, it may cause an explosion. In such a situation, by removing the passenger from the car, if any leakage occurs, the risk of injury is reduced. CNG is flammable. If there is a leak and a fire occurs, there is a risk of people being trapped inside the vehicle.
Apart from this, taking the passenger out of the car reduces the weight of the car, which makes the CNG filling process faster and easier. When there is no passenger in the car, the CNG nozzle can be easily accessed to the tank.
In most of the cases, people get the CNG fitting done from outside, due to which there is difficulty in finding the knob at the time of refilling. Also, the risk increases due to after market tampering.
Safety rules for filling CNG
- Some CNG stations have rules that there should be no passengers in the car during filling.
- Some insurance companies may impose a condition that there will be no passengers in the car during CNG filling.
There is no need to be afraid. It is true that there is a risk of explosion in CNG, but it can be reduced by taking proper precautions. There are trained employees at CNG stations and follow safety protocols.
Take these precautions while filling CNG
- Fill CNG only from official CNG stations.
- Do not smoke or use mobile phone during filling.
- If you smell gas or see a leak, notify station staff immediately.
