A fire officer will pay a moving tribute to a dedicated member of his watch who died while trying to save children from a burning house.

Terry Calpin is to speak about the bravery of his colleague Jeff Naylor on the 19th anniversary of the fire which claimed his life.

He is to speak at Workers' Memorial Day in Keighley town square tomorrow in a safety awareness event backed by the family of the dead fireman.

And in Bradford's Centenary Square there will also be a memorial to people who have died at work organised by Bradford Trades Union Council and Bradford Worker's Health Advice Team.

Mr Calpin, who is now a fire investigation officer, said he vividly remembered the 999 call to a house in Broomhill Walk, Keighley, in 1983.

"Flames were licking out of the downstairs windows and we could hear the children inside screaming," he said.

"Firefighters entered the burning building in an attempt to rescue them and bring them to safety."

Tragically, two of the five children inside died in the blaze and 32-year-old Jeff suffered terrible injuries and died three months later in Pinderfields Hospital.

His brother George, who lives in Selbourne Grove, Keighley, said Jeff was committed to his job and his bravery came as no surprise.

"He just took it all in his stride," he said. "I suppose you just take it for granted when you go to work that you will come back at the end of the day."

He said that Jeff's death was a catalyst for change. The nylon shirts and woollen jumpers that firefighters wore were soon replaced by hi-tech protective suits. "The mask Jeff was wearing was the only thing that kept his face from being burnt," said George.

An appeal in the Telegraph & Argus also raised more than £20,000 for the Fire Service's National Benevolent Fund.

Mr Calpin, who will be joined by Keighley MP Ann Cryer at the event at 10am in Keighley, said it had been the worst night of his career.

"Nothing can prepare you for the despair and sadness of losing a friend and colleague in such dreadful circumstances.

"I remember to this day the drive back to the fire station in numbed silence."

Keighley Worksafe Project. which has organised the memorial with Keighley Trades Union Council. is a registered charity that provides free occupational health safety information and training.
