Hand Arm Vibration Syndrome (HAVS) Monitoring

Hand-arm vibration is vibration transmitted from work processes into the hands and arms. It can be caused by operating hand-held power tools and hand-guided equipment, such as powered floor polishers or lawnmowers, or by holding materials being processed by machines. Regular exposure to hand-arm vibration can lead to conditions like Hand-Arm Vibration Syndrome (HAVS), vibration white finger and carpal tunnel syndrome. These conditions can cause symptoms such as tingling, numbness, pain, and loss of strength in the hands and arms. Note, smokers or workers with poor circulation may be more susceptible to HAVS.

Monitoring helps pinpoint specific tools or processes that generate excessive vibration, allowing targeted interventions such as equipment maintenance, tool replacement, or changes in work practices.

What to expect during hand-arm vibration monitoring

An Environmental Monitoring Technician will visit your department to measure equipment vibration using a HAVS Monitor. A probe will be attached to the equipment handle for this purpose. After monitoring, a report with readings and advice will be provided. A staff member will need to operate the vibrating machinery or equipment during the assessment.

HAVS measurements are taken every two years or when there are changes such as new staff, new equipment, or equipment modifications.
