The damaged high-pressure gauge of the compressed natural gas (CNG) cylinders led to a gas leak on the bus that caught fire near Gokuldham market bus stop in Goregaon (East) on May 3, states a report submitted by the Brihanmumbai Electric Supply and Transport (BEST). The report was tabled before a BEST panel on Monday.
The BEST committee, the policy-making body of the undertaking, had asked the administration to submit a detailed report at the earliest.
The report adds that inspection of the charred bus, done by a team of experts, revealed that no other parts of the fuel system, besides the high-pressure gauge, were damaged in the fire. The expert panel comprised executives of the bus manufacturer (Tata Motors), pressure gauge manufacturer and hydro test experts.
Even the hydro test certificate for the cylinders was valid until November 2020. The report adds about 200 bar CNG could have leaked from the cylinders and damaged the high-pressure gauge after accumulating under the bus.
“The fire could have been triggered because of some external source,” reads the report.
The bus was on its way to Nagari Nivara from Goregaon station when it caught fire. Three passengers, who were on board when the incident occurred, escaped unhurt. The bus had clocked more than 5.5 lakh kilometres and had undergone preventive maintenance on April 5.
As a precautionary measure, the undertaking has decided to replace pressure gauge of 828 overaged CNG buses. The BEST currently owns 1,885 CNG buses. In addition, the buses will be inspected on weekends.
