The family of a Grangemouth dad-of-two who died in an accident on a building site are still waiting for answers.
More than four years after Jason Daisley’s death the reason he reversed his dumper truck into a pit remains unclear.
He was crushed when his nine-tonne vehicle rolled over him at the site of a new £68 million whisky bottling plant in Fife.
His wife, Tracy (37), was left to bring up their two little girls, Hayden, now six, and Teigan (5) at the family home in Taylor Court.
This week a sheriff found that if Mr Daisley had been wearing his seatbelt, his death might have been avoided.
The tragedy occurred on August 26, 2010 but the findings of a fatal accident inquiry held at the end of last year were only revealed this week.
Several witnesses told of seeing Mr Daisley put the dumper truck into reverse and speed backwards while looking forwards.
In his report Sheriff Andrew McCulloch said: “Although some witnesses had their own theories, the reason for the deceased driving as he did will remain unknown.”
No defects were found on the dumper truck.
Mr Daisley had worked with sub-contractors Ground Developments Ltd on the Diageo site near Leven for two weeks prior to his death.
In his findings following the FAI in Kirkcaldy, the sheriff noted the dead man had passed courses and was a trained operator of the vehicle involved.
He added: “All witnesses who knew the deceased confirmed that he appeared to be a proficient driver, if occasionally a little unsure.”
His report concluded: “The most obvious precaution which could have avoided death was the wearing of the fitted seatbelt by the deceased. All witnesses who worked on the site confirmed that it was company policy to do so, and that training confirmed the importance of wearing a seat belt.
“No witnesses could explain why the deceased was not wearing his at the time of the accident.
“Had he been wearing it, the probability is that he would have remained in his seat, thus avoiding death. Clearly the precaution would not have avoided the accident, but any injury sustained would have been significantly reduced.”
At the time of her husband’s death, a devastated Mrs Daisley said: “His girls were his life. Everything he did was to give them a good future.”
Relatives vowed his daughters would be brought up to know how much their dad loved and was proud of them.
