Aspiring young fire fighters have been injured on visits to the region’s fire stations.
The cadets, some as young as 14, were among visitors to fire stations in West Yorkshire who suffered injuries.
A report by West Yorkshire Fire Service revealed that young fire fighters, visitors to stations and members of the public had been injured in one year.
The brigade have earmarked nearly £1m to pay for 225 accidents to visitors, staff and personnel at West Yorkshire Fire and Rescue Service sites in one year.
The bill has soared from £147,000 two years ago to £915,350.
David Williams from West Yorkshire Fire Brigade Union, said: “I should imagine a majority of these will be slips and trips.
“Accidents are always an emotive subject.”
The top five most common causes of accidents recorded in 2011 and 2012 include back pain, slips, trips and falls, contact with sharp objects and exposure to heat, fire or hazardous substances.
But a report has said the force has seen a reduction in the number of accidents by 25 per cent from the previous year.
Around 80 per cent of the incidents involved operational personnel and firefighters and 20 per cent of them involved non-operational staff.
A report by the fire service highlights the total cost of accidents, which includes insured and non-insured costs, has shot up over the last two years as a result of two incidents.
Reserves have increased following the Ilkley ladder accident in 2011 which saw three firefighters seriously injured.
The rise is also attributable to the Bingley pit accident which involved a senior firefighter being found at the bottom of a fire engine inspection pit two years ago while he was carrying out routine duties.
