Authorities Managing Butane Gas Leak Disposal
The ongoing operation to dispose of the leaked butane gas is being managed through a multi-agency effort employing specialized equipment and controlled combustion methods, with the process expected to conclude within the next two to three days. The situation is currently deemed under control, with gas readings significantly reduced, allowing for the return of evacuated residents and students.
Controlled Combustion and Monitoring
The primary method for gas disposal involves a controlled burning-off process utilizing two mobile incinerators, operating under the close supervision of Hazardous Materials (Hazmat) and Petronas teams. To expedite this process, a second mobile incinerator was installed. The combustion cannot be conducted on a large scale due to potential environmental impacts, necessitating a more time-consuming approach.
Gas Detection and Safety Perimeter
The Malaysian Fire and Rescue Department (JBPM) has deployed two high-tech devices for detecting dangerous and flammable gases. The Hazmat team conducts gas detection and readings every two hours to monitor the situation. A safety perimeter of approximately 500 metres is being maintained around the affected site to ensure public safety.
Air and Pipe-Based Disposal Methods
In addition to ground-level monitoring, drones equipped with specialized devices, operated by Petronas and the Department of Environment (DOE), are used to monitor gas levels from the air. Furthermore, plans are in place for Petronas to inject nitrogen into the pipe to safely dispose of any remaining butane.
Impact on Local Activities
Inspections have confirmed that gas readings are now minimal, recorded only at the tunnel entrance where the leak originated, with zero readings at five other monitored locations. This improvement in readings has led to the decision to allow 20 evacuated tahfiz students to return to their madrasah. However, construction work at the adjacent East Coast Rail Link (ECRL) site remains temporarily suspended until the gas disposal is fully completed.
