Hand Arm Vibration System from Castle

Hand-arm vibration (HAV) is vibration transmitted into workers' hands and arms from work processes such as operating hand-held power tools. Frequent exposure to moderate- and high-intensity HAV can cause hand-arm vibration syndrome (HAVS). HAVS is a general term that refers to the damage to nerves, blood vessels, muscles, and joints in the

The number of holes that can be drilled for a particular tool and given diameter, depth, work piece material and consumable in a working day before the EAV and ELV (shown in brackets) are given in the productivity data section. The red value is the number of HSE points per hole for the given tool and application. 66 min. concrete 40 N/mm² TE.

Recommendation 2: Tool manufacturers should modify and redesign tools to reduce hand-arm vibration. Tools with reduced vibration levels should be furnished to workers. Purchasers are encouraged to request suppliers to provide evidence that their equipment reduces vibration. More research is needed before a specific standard can be recommended.
HandArm Vibration Exposure Calculator HSE Documents

The length of exposure to hand-arm vibration is measured in metres per second squared (m/s²). You are at greater risk if you use a tool rated above 2.5 m/s² throughout an 8-hour working day. Continuous use of a tool rated above 5.0 m/s² represents a dangerously high risk. If using a variety of tools see the table below. 08457 28 28 28.
