Newport Crown Court heard that employees of Asset International used vibrating tools without proper training or practical controls to reduce vibration risk.
An investigation by the Health and Safety Executive (HSE) found no sufficient risk assessment or health surveillance had been carried out.
Asset International, of Stevenson Street, Newport, pleaded guilty to offences under Regulations 5, 6, 7 and 8 of the Control of Vibration at Work Regulations 2005.
HSE inspector Joanne Carter said: “The serious and irreversible risks from hand arm vibration syndrome caused by work with vibrating tools are well known and guidance has been in place since the early 1990s.
“This case shows there is no excuse for not putting in place a management system which includes risk assessment, control measures, health surveillance and information and training to reduce these risks to as low a level as is reasonably practicable.”
