KUALA LUMPUR, April 1 – A massive gas pipeline fire in Putra Heights, Subang Jaya, is believed to have been caused by a Boiling Liquid Expanding Vapor Explosion (BLEVE), an expert has said.
Datuk Seri Mohammad Hamdan Wahid, former Director-General of the Fire and Rescue Department (Bomba), stated that the explosion likely occurred due to a leak in a flammable gas pipeline. The gas vapour could have lingered in the air before an ignition source triggered a powerful explosion.
“When flammable gas vapour is suspended in the air, it only takes a spark to cause a devastating explosion. The leak could have come from a ruptured pipeline, an open valve, or another failure in the containment system,” he said during an interview on Bernama TV’s Bernama World programme today.

Compliance with Safety Standards
Mohammad Hamdan stressed that all gas pipeline installations in Malaysia must follow international safety regulations, including the Malaysian Standard for Storage, Handling and Transport of Liquefied Petroleum Gases (MS830) and the Malaysian Standard for Storage and Handling of Flammable and Combustible Liquids (MS761). He also pointed out that oil and gas companies must comply with the Compressed Gases and Cryogenic Fluids Code (NFPA 55) to minimise risks.
Advice for Nearby Residents
He urged residents to evacuate immediately and follow Bomba’s instructions to avoid exposure to hazardous conditions.
“This type of fire generates intense radiant heat, which can damage nearby structures and cause further spread. If not controlled, it can lead to a chain reaction of fires in the surrounding area,” he warned.
Challenges in Extinguishing Gas Fires
Oil and gas safety expert Captain MS Affendy Abdul Rani explained that pipeline fires are different from normal fires due to the highly flammable materials involved. These fires burn at extreme temperatures and are challenging to extinguish using water alone.
“The most crucial step is shutting off the gas supply. As long as the gas continues to leak, the fire will keep burning,” he said.
Urgent Action Needed
Former National Institute of Occupational Safety and Health (NIOSH) chairman Tan Sri Lee Lam Thye called for immediate measures to protect residents. He urged Petronas and relevant authorities to:
- Provide real-time updates on the situation, including air quality and health risks.
- Ensure proper evacuation and support for affected families, especially vulnerable groups.
- Conduct a thorough investigation into the cause of the explosion and implement preventive measures.
He also suggested that early detection systems be improved to prevent similar incidents in the future.
Extent of Damage
As of 3.40 pm, the fire on Jalan Putra Harmoni in Selangor has damaged 190 houses, 148 cars, and 11 motorcycles. Fortunately, no fatalities have been reported, but authorities are still investigating the cause of the explosion.
Conclusion
The Putra Heights gas pipeline fire serves as a reminder of the importance of stringent safety measures in the oil and gas industry. Authorities must take swift action to ensure the safety of residents and prevent similar tragedies in the future. — Bernama
