SHAH ALAM, July 1 — Gas supply to areas affected by the Putra Heights pipeline explosion on April 1 will be restored beginning today, according to the Occupational Safety and Health Department (DOSH).
Its director-general, Mohd Hatta Zakaria, said under Phase 1 of the repair and restoration works, a temporary gas pipeline of approximately 210m would be installed to replace the damaged section of the pipe.
Soil strengthening and stabilisation works have been carried out at the site to better support the pipeline, while safety checks also confirmed no leaks or pressure drops.
"The temporary pipeline is scheduled to begin supplying gas again on July 1, 2025, allowing consumers to regain a stable supply," he said in a statement issued by his office.
Hatta said Phase 2 of the restoration project, meanwhile, will involve replacing three new gas pipelines — each about 200m long — at the affected site, with concrete slabs installed to secure and protect the pipes more effectively.
"The engineering design for this phase is currently being finalised and the pipes are expected to begin operating in the third quarter of 2026."
He said this repair effort is crucial to ensure the safe and stable restoration of gas supply for residents and businesses in the affected area.
"DOSH understands the urgent need for residents and businesses to regain a safe and stable gas supply as soon as possible, and will closely monitor every stage of the project to ensure it is carried out responsibly and to restore public confidence in the safety of the gas pipeline system in the area."
According to Hatta, safety remains DOSH's priority, adding that all repair works are done in accordance with internationally-recognised technical codes and standards.
Additionally, he said several geotechnical studies, including soil mapping, analysis of soil and rock layers, and ground movement monitoring, were carried out to ensure the pipeline installation site remains stable and safe in the long term.
"DOSH assures that all works are closely monitored for the safety of not only the workers on-site, but also nearby residents and businesses.
"As an added safety measure, Petronas has been ordered to provide real-time monitoring access to the pipeline's isolation valve system to ensure it can be shut off immediately and functions properly in the event of an emergency."
On April 1, a leak along a Petronas-owned gas pipeline caused an explosion in Putra Heights, which sent flames up to 30m into the sky. Firefighters took nearly eight hours to extinguish the blaze.
The blast left a 9.8m-deep crater and damaged over 400 nearby homes.
A joint investigation into the incident found no signs of foul play, sabotage, or negligence. The cause of the disaster was instead linked to structural failure due to environmental and geological factors.
