Hand Arm and Whole Body Vibration Assessments

Our Services Include:

• Measurement and assessment of hand-arm vibration using human-vibration meters and tri-axial accelerometers
• Measurement and assessment of whole body vibration
• Calculation of maximum permitted daily usage
• Consultancy and advice on control strategies

Hand - Arm Vibration

Workers whose hands are regularly exposed to high vibration may suffer from several kinds of injury to the hands and arm. Hand-Arm Vibration (HAV) is a painful disease and is widespread in those industries where vibratory tools and machines are used. HAVS is a major cause of occupational ill health and it is estimated around five million workers are exposed to HAV in the workplace.

Whole Body Vibration

Whole body vibration is shaking or jolting of the human body through a supporting surface (usually the seat or the floor), for example when driving or riding on a vehicle along an unmade road, operating earth moving machines or forklift trucks, or driving rail vehicles or machinery.
Lower back problems arise from degeneration in the spinal vertebra or degeneration of the discs causing compression and pain. Each year, approximately 3,000 new claims for Industrial Injury Disability Benefit are made in relation to vibration white finger and vibration related carpal tunnel syndrome.

Legal Requirements

New regulations that help both employers and employees to take preventive action from vibration risks in the workplace came into force on 6 July 2005. The Control of Vibration at Work Regulations specify ‘Exposure action values’ (EAV) and ‘Exposure limit values’ (ELV). An exposure action value is the exposure level when action specified in the regulations must be taken. An exposure limit value is the maximum permitted exposure to vibration for an individual worker. The Regulations require employers to:

• Reduce exposure to harmful levels of vibration to a minimum
• Assess the vibration risk to employees
• Provide information and training to those exposed
• Implement measures to reduce exposure
• Provide health surveillance when action levels are reached in order to ensure exposure is below the exposure limit value
