Firefighters across the North West are due to go on strike later today.
Members of the Fire Brigade Union will strike for five hours from midday in a row over pensions.
It is the first of three days of industrial action planned over the Bank Holiday weekend.
A spokesperson for Merseyside Fire & Rescue Service said:
“The public should be reassured that our staff will maintain a significant emergency response capability during industrial action on May 2, May 3 and May 4 and 999 calls will be answered and responded to.
“During any industrial action we always ask the public to show extra care and vigilance.”
