Update noon, Wednesday
An RFS crew has been relieved from duty at the southbound Marulan BP gas leak.
A NSW Fire and Rescue Crew from the Southern Highlands remains onsite.
RFS operations officer Lachlan Gilchrist said police and ambulance remained on scene as a precaution.
He told The Post the gas provider was reasonable confident the exclusion zone could soon be removed.
Emergency services have established an exclusion zone, following a gas leak at Marulan.
A motorist had collided with a gas main at the southbound BP service station on the Hume Highway at about 10.15am, setting off the leak, RFS operations officer Lachlan Gilchrist said.
The gas provider is onsite.
One Marulan RFS crew and police are at the scene.
“We’ve established a 200-metre exclusion zone and the crew is putting a lot of moisture in the air so there’s no spontaneous combustion,” he said.
“The gas company is obviously concerned but is confident it can stop it.”
The exclusion zone applies to the diner and carpark but the rest of the service station is operational.
