IGL to cut CNG supply to vehicles lacking valid hydro-test certificates

Indraprastha Gas Limited (IGL) has announced plans to withhold CNG supplies to vehicles that do not possess valid hydro-test certificates for their fuel cylinders, marking a significant step toward tightening safety compliance in the region. The decision aligns with existing government mandates that require all CNG cylinders to undergo hydrostatic pressure testing once every three years to ensure structural integrity and operational safety.

The hydro-testing procedure is a critical safety measure designed to identify potential weaknesses or corrosion in pressure vessels that could pose risks to vehicle occupants and the public. By denying fuel supply to non-compliant vehicles, IGL aims to create a deterrent effect that encourages vehicle owners to maintain proper certification schedules and prevent unsafe cylinders from remaining in circulation.

Vehicle owners using CNG as fuel are advised to check their cylinder certification status and schedule testing appointments well in advance to avoid service disruptions. The enforcement of this requirement is expected to improve overall safety standards across the region's CNG distribution network, which serves hundreds of thousands of vehicles in the Delhi-NCR area.

IGL's move reflects growing industry emphasis on preventive maintenance and regulatory adherence. Officials expect the implementation to proceed in phases, providing adequate notice to stakeholders for compliance before stricter enforcement mechanisms are activated at fuel pumps across the network.
