Putra Heights residents receive stable gas supply—DOSH

• To ensure maximum safety, several stringent tests were conducted, including non-destructive testing (NDT) on welded joints and a 24-hour pressure test.

KUALA LUMPUR (July 1): Stable gas supply have been restored through temporary piping to the Putra Heights houses affected by the April 1 gas pipeline fire, since Tuesday.

According to the Department of Occupational Safety and Health (DOSH), a temporary gas pipeline measuring approximately 210 metres in length has been installed to replace the pipe damaged in the incident.

“Soil improvement and stabilisation were carried out at the site using a bridge foundation support structure, measuring approximately eight metres by 100 metres, to provide stronger support for the pipeline,” DOSH said in a statement on Tuesday.

In addition, to ensure maximum safety, several stringent tests were conducted, including non-destructive testing (NDT) on welded joints and a 24-hour pressure test.

It added that test results confirmed by DOSH and an independent third party showed no leakage or pressure drop.

It added that phase two of the project will involve replacing three gas pipelines, each approximately 200 m long, at the affected sites. These pipes will be laid on concrete slab structures to ensure long-term safety and durability.

“The engineering design for this phase is currently being finalised, with operations expected to commence in the third quarter of next year,” it said.

In addition, several geotechnical studies, including soil mapping, rock layer analysis, and ground movement monitoring, have been conducted to ensure the overall stability of the installation site.

As an additional safety measure, Petroliam Nasional Bhd (Petronas) has been instructed to provide real-time monitoring access to the pipe isolation valve system, enabling rapid closure in the event of an emergency.

The department also assured that all work will be closely monitored and conducted impartially to safeguard the safety of workers, residents, and nearby businesses.

“DOSH understands the urgent need for residents and businesses to have a safe and stable gas supply restored as soon as possible. We are committed to monitoring every stage of this project to ensure it is carried out responsibly, and to restore consumer confidence in the safety of the gas pipeline system in the area,” it added.

The April 1 fire incident caused 81 homes to be completely destroyed, with structural damage exceeding 40%, 81 homes partially damaged, 57 homes affected but not burned, and 218 homes left unaffected.
