Fire-fighters across Lancashire are due to go on strike tonight in a row over pensions.
Crews across the county will strike from 6.30pm until 11pm and they are also planning a strike to take place on Monday.
Fire bosses say they have enough staff to maintain emergency cover during the strikes but they are urging the public to be extra vigilant.
Speaking ahead of the strike Steve Harman, Fire Brigades Union secretary for Lancashire, said there is no other option.
He added: “I would urge the public to be mindful of the concerns of the fire-fighters and support the fire-fighters in their endeavour to protect their pension scheme.
“We feel this is unfair of the government to make changes to the pension scheme which will make it unsustainable.”
Chief Fire Officer, Chris Kenny stressed the dispute is a national issue between the Fire Brigades Union and the Government.
However he added: “We would urge all members of the public to be extra vigilant however and be aware that for minor fires in particular, there may be a longer wait for a fire engine.
“With these strikes also taking place in the run up to Bonfire Night I would urge people using fireworks and lighting bonfires to take even more care than ever because the public can’t expect the usual level of fire and rescue response.”
There was a strike planned for last month but it was called off as talks continued.
