SLAITHWAITE fire station faces going part-time under plans from fire chiefs.
Firefighters' leaders launched an immediate protest.
Slaithwaite is set to become a retained fire station some time in the 12 months starting next April.
Part-time firefighters will be on call and live or work nearby.
West Yorkshire Fire Brigades' Union spokesman Sean Cahill said: "The union's fear is that these changes are budget-led.
"Slaithwaite firefighters back Huddersfield crews up all the time, but it does not show in the figures.
"Slaithwaite went with Huddersfield to a house fire in Thornton Lodge early yesterday morning - but that would only show up on Huddersfield's statistics," said Mr Cahill.
"Our concern is that if Slaithwaite becomes retained, when Huddersfield needs back-up it will be sent from the fully-manned stations further away, in Elland and Brighouse, as it would be cheaper than calling out retained crews nearby."
In other changes, Batley may lose one of its two fire engines.
Two of the five aerial appliances - special long ladders with firefighters' cages attached - in West Yorkshire face being axed.
But Huddersfield fire station will keep its aerial appliance for now. However, the decision will be reviewed over the next two years.
Deputy fire chief Kevin Arbuthnot said: "We are moving resources from under- deployed areas to busy areas."
He added: "There will be no compulsory redundancies with these changes, so it will be a fairly painless process."
Fire chiefs told yesterday's West Yorkshire Fire And Rescue Authority meeting that money saved by the changes - just some of several made across the county - will be spent on community fire safety projects, in a bid to reduce the risk of people being killed or injured in fires.
The proposals will be put out for consultation until late September.
A final plan will be drawn up in October.
A report to the meeting also said Marsden fire station was in a poor condition and may need to be replaced.
Mr Arbuthnot went on: "It has been known for a long time that Batley has not warranted a second pump and we will reduce it to a one-pump station.
"It is a lower risk station already than many other one-pump stations and is well backed up by Dewsbury and Cleckheaton stations."
He said there would be a significant amount of community fire safety work done in the Batley and Colne Valley areas before any changes were made.
Under the plans, aerial appliances may be withdrawn from fire stations at Stanningley in Leeds and Keighley.
But they will remain at Huddersfield, Leeds and Bradford fire stations.
Mr Arbuthnot said aerial appliances rarely saved lives and the vast majority of calls they went to were false alarms.
"I regard this as waste reduction," he said.
"I was surprised at the level of inactivity of some very expensive resources," added Mr Arbuthnot.
