The plaintiffs named Petronas Gas Bhd, Hong & Hong Homes Sdn Bhd, Pinterest Ventures Sdn Bhd, the Subang Jaya City Council (MBSJ) and the Malaysian government as defendants.

The plaintiffs, led by Loh Poh Heng, have appointed former attorney-general Tommy Thomas as their lead lawyer, reported Astro Awani.

The residents are seeking compensation for losses involving property damage, health issues and emotional distress, as well as justice and transparency from the authorities.

“This is not just a legal claim but an appeal for justice and recognition of our suffering. We want our voices to be heard,” Loh said.

Loh said they believe the tragedy was caused by human negligence and could have been avoided.

“The gas transmission line owned by Petronas Gas was placed too close to our homes, yet the safety measures were inadequate,” said Loh at a press conference in the housing area today.

“Six months after the incident, many victims are still without permanent housing, relying on family support or living in temporary shelters.

“The fire raged for more than seven hours before it was brought under control. Our homes were destroyed, our lives shattered, and many residents suffered serious injuries, including severe burns and lingering emotional trauma.

“Our scars may never heal, but through this civil action, our voices will be heard.”

He claimed that residents were left without clear information after the explosion. He also alleged that the investigation was not transparent and repair works were carried out without explanation to residents whose homes were destroyed.

The gas pipeline explosion on April 1 sent flames soaring over 30m high, with temperatures reaching 1,000°C. No fatalities were reported, but about 150 people sought hospital treatment.

The fire left a crater measuring 21m by 24m and 10m deep. Eighty-one houses were destroyed, 81 more were partially damaged, and 57 were affected by heat or debris.
