A Suffolk farm worker was crushed to death in a field near Bury St Edmunds after failing to follow machinery safety procedures, an inquest has heard.
Darren Prentice, 42, had been driving a tractor towing a de-stoning machine at Howe Hill in Sandy Lane, Rushbrooke on April 17.
It is believed that Mr Prentice, of Kiln Cottages, Rede, had stopped his tractor and climbed onto the machine to clear a blockage, possibly caused by a piece of metal, as he believed the de-stoner was not running.
However, an inquest today (Monday) at Suffolk Coroners Court in Ipswich heard that despite being aware of "safe stop" safety rules, he had failed to switch off the engine of the tractor as he climbed from the cab.
A Health and Safety Executive investigation concluded that it was likely that Mr Prentice was standing on a conveyor belt when the blockage was cleared and which allowed the machine to resume operating.
Fellow worker Tommy Bevan realised that Mr Prentice’s tractor had not moved for about 20 minutes and went to investigate, finding Mr Prentice trapped beneath a metal bar and not breathing.
A disc cutter was used to free Mr Prentice and attempts at resuscitation began before fire and ambulance crews arrived and took over but Mr Prentice was declared dead at the scene.
Assistant Suffolk Coroner Dr Daniel Sharpstone said Mr Prentice died as a result of crush injuries to his body.
Jessica Churchyard from the Health and Safety Executive who investigated the incident, said the de stoning operation had been taking place in preparation for potato planting for Fornham Growers Ltd who farm 4000 acres around Bury St Edmunds.
Adequate risk assessments for operating de-stoning machines had been in place and stickers reminding operators to switch off the engine before getting out were posted inside the tractor cab.
Mr Prentice was familiar with the machine, having taking the manual home with him to read, and had earlier been observed by farm manager Gary Duffield to clear a blockage from the de-stoning machine while following the "safe stop" procedure.
Ms Churchyard said the HSE was satisfied that there had been no breaches of health and safety legislation and no action was planned.
She said that pieces of metal had previously been found in the same field and the one metre long piece which may have caused the blockage to Mr Prentice’s machine was found near the scene of the tragedy.
The HSE investigation had examined why Mr Prentice got onto the machine, said Ms Churchyard. She said: "It may be that if it was blocked it gave him a false impression that it was isolated."
In conclusion, Ms Churchyard said: "The incident arose because Darren Prentice did not follow the correct procedure."
Assistant Coroner Dr Sharpstone recorded a conclusion of accidental death.
