Hand Arm Vibration is vibration transmitted from work processes into worker’s hands and arms.
It can be caused by operating handheld power tools and hand-guided machinery, or by holding materials being processed by machines. Regular and frequent exposure to hand arm vibration can lead to permanent health effects such as carpel tunnel syndrome. Long term effects can severely limit the jobs a person can do, due to intense pain, reduced grip strength or an inability to do fine work, particularly in cold or damp conditions.
The Regulations require that every employer must assess the vibration risks to their employees and determine whether they are likely to be exposed above the daily exposure action value (EAV).
For tools or processes that are used / in operation infrequently, a visual inspection and assessment of risk may suffice. For all other cases, it is recommended that physical measurements are collected for a more detailed exposure assessment.
We can conduct measurements in order to obtain greater certainty on exposure levels.
Equipment of concern includes:
Our experienced and qualified staff use state of the art equipment to determine personal exposure to hand arm vibration. As results can be variable, we consider the operator’s technique, the condition of the equipment, materials being processed, environmental conditions etc. Inspection of working processes and test results allow us to evaluate how effective current control measures are, whilst assessing the risk of harm to human health. We can advise the client in risk reduction and control measures. Our action plans will list alternative work methods and provide guidance on the selection of appropriate protective equipment, a policy for replacing equipment, work and maintenance schedules and design of workstations.
As a client and an employer, your employees are your most valuable asset. They are fundamental to the success of your business and as such you must take action to safeguard their health.
WBV is the mechanical vibration transmitted through the seat or feet of workers - typically those operating mobile machinery such as tractors, forklifts, or earth-moving equipment - while working on rough or uneven surfaces.
Prolonged exposure to WBV is associated with an increased risk of lower back pain, spinal degeneration, and other musculoskeletal disorders. The Control of Vibration at Work Regulations 2005 sets legal limits for daily exposure, requiring employers to assess risks, implement control measures, and reduce exposure to the lowest level reasonably practicable.
We can help with observations for high-risk individuals and advise on the factors that play a critical role in mitigating WBV related health effects, including ergonomic factors such as posture, seat design, and vehicle maintenance.
