Gas leak in supply line was responsible for the fatal explosion at Patharghata area in Chattogram on November 17, said the investigation report of Chattogram district administration on Sunday.

The explosion and collapse of a building killed at least seven people and injured 10 others.

Soon after the explosion Karnaphuli Gas Distribution Company Limited claimed there was no leak in supply line though the Chattogram Fire service and Civil Defence, Department of Explosives and Chattogram Metropolitan Police dissented from the opinion.

After the explosion, three committees were formed to investigate the blast. Members of two committees visited the spot several times.

On Sunday afternoon, additional district magistrate AZM Shariful Hossain submitted the report to the deputy commissioner of Chattogram.

Chattogram district administration formed a seven-member committee headed by AZM Shariful Hossain and asked to submit the report in seven working days.

The officer-in-charge of Kotwali Police Station and representatives of Karnaphuli Gas Distribution Company Limited, Chattogram City Corporation and Chattogram Development Authority, Fire Service and Civil Defence and Department of Explosives were the other members of the committee.

Additional district magistrate AZM Shariful Hossain after submitting the report said that there was a leakage at one point of the gas line, where gas flows from riser to the consumer’s pipeline. This leakage caused explosion in Patharghata.

The 13-page report also recommended five points.

However, after the accident, city’s additional deputy commissioner Abdur Rouf suspected that leaked gas condensed at injured Sandhya Nath’s room and it exploded as soon as she struck a matchstick.

Chattogram Fire Service and Civil Defence deputy director Jasim Uddin echoed what Rouf suspected. 

He pointed out that the gas pipeline of the Karnaphuli Gas Distribution Company Limited was very old.

Department of Explosives inspector Taffazzal Hossain said that the gas riser became old and it could be a reason behind the gas pipeline leak.

Chattogram Development Authority chief engineer Shahinul Islam suspected that gas leakage might be behind the explosion.

However, KGDCL formed a four-member probe committee and submitted its probe report on that afternoon at Petrobangla claiming that the accident was not caused by gas line leakage.
