The Metropolitan Fire Brigade (MFB) has revealed a third of its trucks are off the road, partly because of a pay dispute at its mechanics workshop.

There is a backlog of 30 trucks waiting to be repaired at the workshop and 10 trucks have been sent to help the firefighting effort in New South Wales.

The MFB says it has reached a deal with staff, but work bans are still in place until it is approved by the Fair Work Commission.

The MFB’s chief executive, Nick Easy, says it has enough trucks in the meantime.

“We have about 120 appliances and 81 of those are primary or specialist appliances which are under roof at our 47 stations,” he said.

“So the remainder of the appliances are either spares, they’re used for training of they’re for surge capacity.

“The number of appliances under our stations and our roof, we think, are sufficient.”
