Nearly 30 jobs could be lost across the Lancashire Fire and Rescue region, as brigade bosses consider changing crewing arrangements for stations that hold one appliance.
In a report, to be published later this week, Lancashire's strategy director, Paul Richardson, has looked at activity levels of the six bases in the region that house a single appliance.
The review follows an early change which saw 'day crewing' - where firefighters spend 12-hour shifts at a station - trialled at Rawenstall, Darwen and four other stations in the county. The next two stations in line for the change are Chorley and Nelson, with Morecambe, Skelmersdale, Bamber Bridge and Blackpool's South Shore also being considered.
Fire authority bosses have already being asked to postpone a wider emergency cover review until next year, when the service will have more information about the 2013-2015 financial plan.
Mr Richardson said: "Notwithstanding this, the potential exists to deliver additional efficiency savings whilst maintaining front-line service delivery.
"It is proposed that, prior to the full review being carried out, the service extends its day crewing plus duty system to two further stations."
To put in the new accommodation blocks, the cost is estimated at £500,000 - but the savings made by reducing crews from 28 to 14 would mean annual savings of £370,000 per location, it has been claimed.
