The popularity of CNG vehicles has grown recently due to developments in fuel storage technology. CNG is a common fuel alternative for fleet cars since it is more affordable than petrol or diesel. It is a fuel of compressed methane gas kept in high-pressure cylinders inside cars. CNG vehicles have various designs, including sedans, SUVs, and pickup trucks.

CNG refuelling stations are now widely available at petrol stations, making refuel easier for car owners. There are several benefits of driving a CNG fuelled car, but there might come an instance where the gas would catch fire. This is a rare condition, but we cannot neglect the probability. Let's dive deeper into the topic to understand the causes of fire in CNG cars and how to stay safe.

While we're discussing car safety, it is crucial to invest in reliable car insurance. Various car insurance online India plans have grown in registration over the past few years due to their practicality and usability. However, the type of fuel the car runs on can affect the insurance cost and policy features.

Causes of fire in CNG cars
1. Fuel leaks
One of the main reasons for fire in CNG vehicles is fuel leaks. Because the fuel is kept in high-pressure cylinders, leaks could result from any damage to the fuel system. Due to its extreme flammability, CNG can catch fire when touched by heat or sparks.

2. Accidents or collisions
CNG vehicles are more likely to catch fire in an accident or collision. In a crash, the high-pressure cylinders holding the CNG fuel may break and catch fire.

3. Refuelling
In CNG vehicles, refuelling might also be a fire hazard. Transferring fuel from the dispenser to the high-pressure cylinders entails the creation of a static charge, which has the potential to ignite the fuel.

4. Inadequate maintenance
Routine maintenance is necessary to ensure the system operates properly. Components may become worn or damaged if the fuel system is not maintained.

5. Temperature extremes
The fuel system may be damaged or malfunction due to the fuel's ability to expand or contract under extreme temperatures.

6. Electrical malfunctions
In CNG vehicles, electrical issues can potentially result in fires. A malfunction in the electrical system might cause fuel to overheat and ignite because the electrical system and fuel system are interconnected.

Safety tips for CNG vehicles
When driving a CNG vehicle, certain safety precautions must be taken. Here are a few tips for driving a CNG vehicle safely:

1. Inspect the CNG kit regularly
Check the CNG kit frequently for any indications of wear and tear. If you see anything odd, get it fixed straight away.

2. Turn off the CNG supply when not in use
Turn off the CNG supply valve when the automobile is not used to stop gas leakage.

3. Don't overload the car
An overloaded CNG car may have high cylinder pressure. Observe the recommended weight restrictions for your vehicle.

4. Install your CNG kit at a certified shop
To ensure that a CNG kit is installed accurately and safely, it must be done by a workshop that has received certification. Before using the kit, always request a certificate of installation.

5. Avoid smoking in vehicles
Due to its extreme flammability, CNG can catch fire when in contact with a spark or flame. Therefore, avoid smoking or lighting cigarettes inside the car.

6. Maintain good ventilation in the car
For CNG vehicles, proper ventilation is essential to prevent gas build-up. To keep the car well-ventilated, keep the windows open at all times or turn on the air conditioner.

7. Observe traffic laws and drive safely
Drive safely and follow the regulations of the road to prevent collisions. In an accident, shut off the CNG supply immediately and leave the vehicle.

8. Avoid keeping anything flammable in the car
The fire or explosion risk increases if flammable items, such as petrol, aerosols, or chemicals, are kept inside the vehicle. Avoid keeping these things in your car.
CNG is a preferred alternative fuel for vehicles due to its affordability and minimal environmental impact. However, compared to traditional gasoline-powered vehicles, CNG vehicles have a higher chance of catching fire. Following the proper safety precautions and being aware of the causes will help prevent them and guarantee safe driving.
