With rising fuel prices, more citizens are shifting to CNG vehicles, causing their numbers to triple in the past three years. However, authorities warn that many of these vehicles are skipping mandatory hydro testing, putting passengers at serious risk.

At several CNG refueling stations, staff reportedly fill gas without checking the cylinder’s fitness certificate. Faulty or rusted cylinders, when filled under high pressure, can explode turning negligence into potential tragedy.

What happens during hydro testing?

In this process, the cylinder is filled with liquid at a set pressure to detect leaks, rust, or cracks and assess its capacity. After a successful test, the RTO issues a new fitness certificate.
