SEREMBAN: Just days after the massive Petronas gas pipeline explosion in Putra Heights, Selangor, irresponsible people allegedly set fire to rubbish in a high-risk area near what authorities believe is a gas pipeline beneath the ground at Taman Bukit Sendayan.

The burning of the waste occurred on Thursday, Sinar Harian reported.

The fire covered an area of approximately 200 square feet, about the size of a small room or car park space.

Seremban 2 Fire and Rescue Department senior fire officer I Mohd Nizam Yom said the department received information about the fire incident at 8.30am.

"As soon as we arrived, we found that there was a debris fire covering an area of about 200 square feet.

"We took approximately 15 minutes to control the fire from spreading, and the operation was fully completed at 10.14am," he said.

Nizam said the site was an illegal burning area, consisting of old furniture, boxes, and plastic items.

What was concerning was the presence of a warning sign indicating a gas pipeline route near the burning area, he said.

"I can't confirm if the fire was directly along the gas pipeline route, but there is definitely a warning sign in the area," Nizam said.

More than a hundred people sought medical treatment in hospitals on Tuesday following the Petronas gas pipeline explosion in Putra Heights.

The towering inferno which happened on the outskirts of Kuala Lumpur, was visible for kilometres and lasted for several hours, forcing hundreds of residents to evacuate.

The incident occurred on the second day of Hari Raya, shocking the local community during the festive holiday period.
