Homes and Property | Home PageBuilder gets three years after labourer killed by falling wallBen Bailey12 April 2012A builder was today jailed for three years for the manslaughter of a teenage labourer who was the youngest person on record killed on a construction siteAdam Gosling, 15, was crushed to death by a collapsing wall in April 2007 when left to work unsupervised by boss Colin Holtom.He died instantly from massive head injuries when the wall fell on him as he worked as a £25-a-day labourer in the grounds of a north London mansion.Holtom had left Adam and his brother Dean, 18, to knock down the unstable seven-metre long structure by an outdoor swimming pool at a property in Hadley Wood.The 64-year-old, of Meadow Way, Latchingdon, Essex, was said to have had a "laissez faire" attitude to safety.He pleaded guilty at the Old Bailey last week to a charge of manslaughter by gross negligence.Judge Christopher Moss today told him: "You adopted a cavalier and thoroughly irresponsible attitude to the brothers' safety."Martyn Bowyer, prosecuting, said that as a 15-year-old Adam should never have been allowed to carry out such work, while Holtom had failed to provide safety equipment such as hard hats or steel-capped boots.He told the court: "He is the youngest person to be killed on a construction site that the Health and Safety Executive are aware of and he simply should not have been employed to do what he did at that age."Darren Fowler, 47, a contractor of Parkland Avenue, Essex, was jailed for 12 months after he admitted breaching health and safety law and running a company while disqualified from being a director.MORE ABOUTEssex, EnglandMansionsNorth LondonProperty
