Scott Ife, 30, from Bridgnorth, was working for 2 Counties Construction (Midlands) Ltd when the incident took place on 8 June 2020.
The company had been hired as the principal contractor overseeing the refurbishment of agricultural barns into houses on Humber Lane in Telford.
Working alongside another employee, Ife, who was 27 at the time, was laying the blocks to form the gable walls for a two-storey extension. The pair set up a working platform using Youngman boards on the first floor of the property.
As there was an unprotected stairwell opening in the property, one end of the Youngman boards was unsupported.
While leaning over to point up the blocks in the gable walls, the worker lost his balance before falling onto the unsupported Youngman boards and through the stairwell opening.
He fell four-and-a-half metres onto the concrete floor below, fracturing his skull and damaging his facial nerve. The man was hospitalised for three days following the incident.
An HSE investigation identified a series of failings on the part of 2 Counties Construction (Midlands) Ltd including a lack of suitable controls for preventing falls into the building and through the stairwell openings. There was also inadequate planning, a lack of selection of equipment for working at height and inadequate site management arrangements.
2 Counties Construction (Midlands) Ltd, of Worcester, pleaded guilty to safety breaches and was fined £12,000 and ordered to pay £4,139 in costs at Cannock Magistrates’ Court.
HSE inspector David Brassington said, “This incident could and should have been easily avoided. Work at height needs to be properly planned and managed to ensure that appropriate precautions are used.
“We are fortunate that the injuries resulting from these failings were not more serious.”
