A 63 year old woman had to jump away from a runaway platform from a height of about 1.4 metres as it accelerated down a ramp and towards a greenhouse door during the incident on 25 July 2013.
She was on crutches for several months, is still unable to stand for very long and has not been able to return to work.
The salad company was prosecuted on 11th July 2014 by the Health and Safety Executive (HSE) after an investigation found that more could and should have been done to prevent the incident.
HSE told Chelmsford Crown Court that the company had not adequately identified the risk the sloping floor posed to workers using the mobile platforms, known on site as electric trolleys. The platforms were found to be in need both of numerous repairs and better guard rails to prevent falls.
The court heard that workers used the platforms to pick bell peppers at heights of up to three metres. They were designed to run on level ground but were not fitted with brakes. On the day of the incident, the employee was picking bell peppers close to the top of a ramp which led into a greenhouse. When she was a metre away from the slope she pushed the trolley across the aisle to the opposite row of pepper plants and set the controls to make the electric trolley travel away from the ramp.
However, when she pressed the accelerator the trolley travelled towards and down the ramp instead. She jumped off the front of the trolley and tried to stop it hitting the greenhouse door, but in doing so she was knocked unconscious.
Shortly afterwards, the company fitted bollards at the top of the ramp which would have prevented the incident.
The company was fined £22,000 and ordered to pay £8,830 in costs after pleading guilty to breaching section 2(1) of the Health and Safety at Work etc Act 1974.
Speaking after the hearing, HSE Inspector Sue Matthews said:
“Work at any height is inherently very risky, and it has to be properly planned, controlled and supervised.
"The risk to workers using trolleys near to the ramp was known to the company but no action was taken to provide adequate protection.
“Employers must always assess the risks to employees at work and take the necessary steps to ensure their safety. This worker sustained a serious head injury and is still unable to return to work as a direct result of [the company's] failure to manage the risks of this operation.”
