But executives have rebuffed their push for a separate Fire and Rescue call centre, instead revealing plans for a review of the territory's emergency communications hub, which could lead to firefighters stop taking triple-0 calls altogether.

ACT Ambulance Service and ACT Fire and Rescue staff currently share the triple-0 ComCen at the Emergency Services Agency's headquarters in Fairbairn.

Trained firefighters man the phones for fire-related emergency calls, while ambulance staff sit just across the room, taking calls directed to ACTAS.

But the shared space has led to some concerns for firefighters.

A series of six internal workplace health and safety notices, known as Provisional Improvement Notices or PINs, were issued by an ACT Fire and Rescue workplace health and safety officer last week.

They warned that the traumatic calls being dealt with by ambulance staff - which can include babies who have stopped breathing and instructing attempts at CPR and resuscitation - were being constantly overheard by firefighters.

Particularly difficult calls often require debriefings for ambulance staff, something that firefighters say was also occurring within earshot.

The PINs warned this was contravening work health and safety laws, and exposing firefighters to trauma that in some cases reminded them of difficult cases they had experienced. They urged the ESA to remove firefighters from the triple-0 centre in the short-term, and put them back into the old triple-0 call centre in Curtin, which is still used as a back-up and training facility.

But ESA commissioner Dominic Lane said that it was simply not appropriate to split the call centre.

Commissioner Lane said the triple-0 centre would soon be reviewed by ACT Treasury. He said one of the main options he expected to be looked at was replacing the Fire and Rescue triple-0 contingent with trained call takers, who are not operational firefighters, but preferably have fire experience.

The review is also likely to look at making the need for "recline areas", or rooms where firefighters can sleep while on shift, redundant through a new demand-driven roster system.

"What everyone acknowledges is that in a ComCen, you do take calls that obviously can be quite traumatic given the circumstances," Commissioner Lane said. "And what we have to look at as part of this review, I believe, is to question whether it's appropriate for firefighters to be doing that role," he said.

"That is something I think we need to explore - it certainly matches how it's done here with police and the changes we've made to ambulance over recent years."

The ESA has put in other short-term measures to deal with the firefighters' concerns, including asking for ambulance debriefings to take place outside the ComCen where possible.

They have also pledged to undertake minor renovations to provide more room in the centre, so firefighters can distance themselves from the calls.

Commissioner Lane said they are also looking at a larger expansion of the triple-0 centre, a process he said was well and truly under way.

He denied that the complaints were symptomatic of broader tensions between firefighters and ambulance staff in the triple-0 call centre and other co-located stations.

"[Co-locating] is the way to do it. You've only got to look at our new West Belconnen station," he said. "It's a really good example of how you can properly co-locate on the ground."

The review into the ComCen is expected to begin in December.
