Firefighters were called to a house fire in Wakefield as some of their colleagues took strike action today.
But the call to Denby Dale Road at 1.57pm turned out to be a false alarm.
Crews across the district took industrial action between 10am and 2pm as the dispute over pensions between the Fire Brigades Union (FBU) and government continues.
West Yorkshire Fire and Rescue Service said during that time it only received the one 999 call in Wakefield,which was caused by a small, controlled fire, outside the house.
It was attended by firefighters and community response operatives who did not strike.
The service said it was called to 13 incidents across the county. Eight were false alarms.
Assistant Chief Officer Dave Walton said: “The number of calls received during this period of industrial action has reflected what we would expect at this time of day on a Wednesday.
“A significant number of the calls attended were received from automatic fire alarm systems, and ultimately proved to be false alarms.
“I would like to thank the public of West Yorkshire for taking extra care during this period of strike action, allowing us to ensure that those that needed our help were able to get it.”
The FBU is fighting against plans to introduce a new pension scheme which includes raising the age of retirement for firefighters from 55 to 60.
