HAV-Sentry

Employers have a duty to limit the employee exposure to Hand-Arm Vibration as much as practically possible. The HAV-Sentry system has been developed to provide real-time alerts based on personalised measurement of real-time hand-arm vibration exposure, preventing overexposure and driving the formation of robust control measures. The system comprises a unique glove that measures the vibration exposure on the human hand using a built-in Vibration Sensing and Alert Unit (Aegis), the ID Tag to personalise the Vibration Sensing Unit, the Docking Station for charging the Aegis and downloading data, and the software which stores the personalised data for each operator.

What is HAVS?

Hand-arm vibration syndrome (HAVS) is caused by occupational exposure to vibrating powered hand tools which are used for significant lengths of time. The Control of Vibration at Work Regulation 2005 has set the following exposure limit values and action values:

(a) the daily exposure limit value is 5 m/s2 A(8);
(b) the daily exposure action value is 2.5 m/s2 A(8).

The measurement of vibration is mainly based on BS EN ISO 5349-1:2001 for the hand and arm, and is defined by three variables: frequency, intensity of the displacement or maximum acceleration suffered by the body, and direction, composed of three orthogonal axes: x (from back to front), y (from right to left) and z (from the feet to the head).

Specifications - Aegis Vibration Sensing and Alert Unit

The textile embedded monitoring technology, represented by the Aegis Vibration Sensing and Alert Unit, is assembled in a replaceable liner glove, to be worn with or without protection gloves. Vibration exposure levels are calculated based on real-time acquired vibration data by the minimally intrusive sensing unit found in the palm. Sound and visual indicators provided by the control unit found on the back of the hand inform the wearer when the threshold exposure action and limit values are reached.

Note: The HAV-Sentry system adopts the hand-held adaptor design detailed in the Annex D of the BS EN ISO 5349-2:2001. In addition, it measures the gripping force applied by the operator. Although no current guidance exists to evalute this additional factor it is recognised it is relevant and important to improving vibration risk assessment.
