Sheffield Daily Telegraph – Thursday 05 July 1917
At the Barnsley West Riding Court, yesterday, Tom Westwood, trammer, of Great Houghton, pleaded not guilty to a charge of committing a breach of the Coal Mines Act.
Colonel Hewitt, who prosecuted, said on June 15th an ordinary safety pin was found inserted through the covering cable conveying electric power in the pit. The cable carried volts, and one third of that power was sufficient to kill a man.
Defendant said he did not realise the danger of his action, and he could not say why he did it.
He was fined 40s. and costs.
