Matthew Fulleylove’s head became trapped between two machines running on tracks at concrete beam manufacturing plant Treanor Pujol on Pontefract Road, Stourton, on June 5 2014.
A jury returned a narrative verdict after a four-day inquest at Wakefield Coroner’s Court.
The inquest heard Mr Fulleylove, 30, was in a recess area before he became trapped between a Prensoland saw and a bed cleaning machine as they passed on tracks.
Workers were able to free him and a colleague tried to revive him.
But Mr Fulleylove had suffered a fatal head injury and was pronounced dead at 12.01pm that day.
The jury foreman said Mr Fulleylove, of Ash Court, Killingbeck, was recruited as a fork lift truck driver at Treanor Pujol in 2013. He suffered an injury in October 2013 and was moved to a new role.
The inquest was told Mr Fulleylove had between six to 12 months experience of working on the Prensoland saw before the accident.
The foreman said: “There was no formal training documentation identified for the Prensoland saw prior to the accident.
“The company’s unwritten training policy was for an experienced charge hand/saw operative to informally train new staff.
“The training was based on the charge hand’s judgement with no formal competencies documented.
“The company did not identify a need for formal training when the machines passed as they did not identify this as a risk.”
