Absolutely safe
Do you believe that natural gas is the safest form of motor fuel?
The autoignition temperature of CNG is about 550 °C, at the same time, gasoline and diesel fuel are already burning at a temperature of just over 250 °C.
At the same time, the lower concentration limit of explosiveness is much higher than its competitors, at the same time, vapors from spilled gasoline still pose a danger to humans.
Let's take a look at the picture:
One of the reasons for the prejudice against the use of compressed natural gas as a vehicle fuel is the high pressure of compressed natural gas in cylinders.
In this case, for compressed natural gas tanks:
1. have multiple safety margin (2);
2. shatter-proof;
3. undergo a series of tests for resistance to destruction when falling from a height, shooting from a firearm, exposure to extreme temperatures, open flames and more;
4. installed in the least vulnerable and, according to statistics, less frequently damaged parts of the car:

In addition, natural gas is lighter than air and tends upward when it leaks, quickly "dissolving" in the atmosphere.
