The company, which maintains aircraft components, pleaded guilty to breaching reg 5 of the Control of Vibration at Work Regulations. It was fined £80,000 and ordered to pay costs of £25,297.
The Health and Safety Executive (HSE) visited the site in June 2015 after the company reported under RIDDOR that an agency worker had developed bilateral carpal tunnel syndrome. It found that up to six workers carrying out maintenance on aircraft vacuum toilets had been exposed to hand-arm vibration from a Vapormatt wet-blasting cabinet. This is an enclosed unit with gauntlet openings for a worker to clean the toilet components using a foot pedal-operated blast gun that sprays hot water and abrasives.
HSE inspector Helen Turner found BAAE had not risk-assessed the blasting cabinet's use because it "hadn't recognised that there was a potential risk from vibration".
She told IOSH Magazine "there is no safe level" after the investigation revealed exposure to vibration was likely to have been below the action value of 2.5 m/s2 A(8) -- A(8) is the average exposure over an eight-hour shift.
An occupational health nurse identified that the agency worker had a problem with his hand and organised a specialist referral, after which he was diagnosed with the condition.
Soon afterwards BAAE implemented a safe system of work to control the gun's water pressure, limited its use and provided staff with clear instructions and training. It also improved the pre-cleaning of components to minimise how long they had to be treated in the cabinet.
"Those measures reduced the need to hold [the components and the gun] so workers are not directly in contact with the vibration," Turner said.
Judge Jeremy Jenkins determined that BAAE's culpability was medium and set the harm category as 4. In fixing the fine, he started at £130,000 -- the top end of the range for a medium-sized firm -- before reducing it to £120,000 to reflect its good health and safety record. He awarded a full discount for the early guilty plea.
Eddie Ely, a chargehand at Forterra Building Products, and a group of coworkers were cleaning a conveyor when the accident happened on 8 July 2017. The conveyor’s guards had been taken off to help remove a blockage, but the electrical power supply had not been isolated, Burnley Magistrates’ Court was told. Forterra was fined £200,000 and ordered to pay £7,530 costs after it admitted breaching s 2(1) of the Health and Safety at Work Act.
The Symmetry Medical Sheffield employee had one finger amputated and sustained impact damage to another. Sheffield Magistrates’ Court was told that the injured worker was using a pedestrian pallet truck to move a hardness tester – equipment that measures the hardness of metal – when the accident happen on 8 August 2016.The machine was resting on a stand that did not have suitable channels for the truck’s forks. As the worker lifted the stand, the machine toppled and struck the worker’s hand.
Gaskells (North West) and its director Jonathan Gaskell were sentenced both for their part in the death of Polish national Zbigniew Galka in 2010, and for continuing to operate the baler unsafely for up to five years after the fatality.A joint Health and Safety Executive (HSE) and Merseyside Police investigation found that the 39-year-old worker was able to get into the machine at Gaskells (North West) site in Bootle on 23 December 2010 without switching off and isolating the machine.
Only two-in-five manufacturers surveyed (42%) said FFI, introduced in 2012 to make dutyholders pay for notification of minor breaches, had made them think less favourably of the regulator, down from almost three in five (56%) two years ago. The proportion saying FFI made them less likely to ask a visiting inspector for advice had also fallen from 57% to 41%, despite inspectors being obliged to charge them £129 an hour for notification of any material breaches they find during site visits.
Aylesbury Crown Court was told last week that the ballistic separator, which separates organic and inorganic waste, had not been isolated from the power supply when cleaner Rafal Swiadek, 42, climbed into the top level. The machine was switched on from the control room and he was fatally injured.
