The tower had been cobbled together from different manufacturers’ parts and had no edge protection.
His employer has now been fined £5,000 plus £5,000 costs.
The 43-year-old man from West Derby, who has asked not to be named, suffered a brain haemorrhage, fractured skull and collapsed lung in the incident at Croxteth Sports & Wellbeing Centre on 18 January 2011. His injuries also included a broken collar bone, ribs, wrist and fingers.
He was in intensive care for two weeks and his brain injury has had a long-term impact on his personality. He has also been unable to return to work as a result of his injuries.
His employer, CME Ceilings Ltd, was prosecuted by the Health & Safety Executive (HSE) after an investigation found the scaffolding tower the company provided for the job was unsafe.
Liverpool Magistrates' Court was told yesterday (18 September 2012) that the firm had been hired to install a suspended ceiling at the sports centre on Altcross Road in Croxteth but had made a last-minute change to its plan.
It had originally intended to use a scissor lift to reach the ceiling but did not arrange for the equipment to be delivered to the site, and so used a scaffolding tower instead.
The court heard the brakes on the wheels of the scaffolding tower had not been applied to stop it moving and there was no edge protection, including boards and rails, around the work platform to prevent employees falling off.
The man fell approximately two metres to the concrete floor below when the tower started to move across the room as he was working.
The HSE investigation found the scaffolding tower had been made up of parts from several different manufacturers, all of which were in a poor or damaged condition.
CME Ceilings Ltd, of Domville Road in Broad Green, pleaded guilty to breaching the Health and Safety at Work etc Act 1974 by failing to ensure the safety of employees.
Speaking after the hearing, HSE inspector Mark Baker said: "One of CME Ceiling's employees has suffered severe physical and mental injuries that will affect him for the rest of his life.
"The scaffolding tower the company provided simply wasn't up to the job and his life was put in danger the minute he started to climb it.
"This case should act as a warning to firms not to cut corners and to make sure they use the right equipment for the job they're doing."
