CNG Car Explosion at Karjan Toll Plaza Raises Safety Concerns
By Drooid · · How we work
Incident Overview
On the afternoon of October 1, a CNG-powered car exploded while being refuelled at a station on National Highway 48 opposite the Jindal Company in Karjan, Vadodara district, Gujarat. The vehicle’s cylinder burst, igniting a fire and a blast that shattered the rear body, scattered glass and metal fragments, and damaged two nearby parked vehicles and parts of the station’s infrastructure. The driver had stepped out and attendants were at a safe distance, resulting in no injuries or fatalities. Fire crews and police secured the site and restored normal operations after the blast.
Background on CNG Refueling Safety
India’s Petroleum and Natural Gas Regulatory Board mandates that occupants exit a CNG-powered vehicle while it is being refuelled. The gas is injected at 200–220 bar—20–40 times the pressure of a domestic LPG cylinder—creating substantial mechanical stress on cylinders, valves and piping. Improper installation, corrosion, or unauthorised kits can compromise system integrity under such pressures.
Investigation and Official Response
Vadodara Superintendent of Police Sushilkumar Agrawal opened a formal station-diary entry and launched an inquiry. He said investigators will verify whether the vehicle’s owner complied with required safety measures and will determine any lapses before deciding further action.
The police have engaged the Forensic Science Laboratory (FSL) to examine the vehicle and submit a technical report. Depending on the findings, authorities may write to the manufacturer and issue a public safety advisory.
Potential Causes and Knowledge Gaps
Preliminary reports suggest a possible leak in the vehicle’s CNG kit or a faulty cylinder valve, while some experts note that unauthorised or poorly maintained kits can fail under high-pressure filling. The exact cause remains undetermined, and investigators have not ruled out a fault in the refuelling equipment itself.
Safety Recommendations Highlighted by Experts
Industry observers stress regular inspections of CNG kits and cylinders at certified workshops, emphasizing checks of valve condition, piping and overall integrity. They advise against DIY repairs or the use of non-certified components, recommending that only approved parts and trained technicians handle CNG installations. Maintaining a clear distance from the vehicle during refuelling is reiterated as the single most effective precaution.
