Hy-Ten Limited has been fined £13,000 after two tonnes of steel rebar being moved by crane fell onto a worker, breaking both of his legs.
HSE prosecuted the company after investigating the circumstances of the incident in January 2014 at Hy-Ten's factory in Bridle Road, Bootle.
At Sefton Magistrates Court, Hy-Ten pleaded guilty to a breach of Section 2(1) of the Health & Safety at Work etc. Act 1974.
The company was fined £13,000 and must pay almost £7,000 in costs and a £120 victim surcharge. HSE's case was that the task gave rise to substantial risks which should have been identified in a suitable and sufficient risk assessment, embodied a safe system of work and implemented with appropriate training.
Hy-Ten describes itself as the exclusive UK manufacturer and supplier of Bamtec, concrete slab reinforcement steelwork that comes in a roll.
Hy-Ten declined to comment.
