How do I know if my operators are at risk from HAV?

First and foremost you should assess the risk for each operator who uses hand held power tools that vibrate. The degree of risk can be ascertained from two pieces of key information:
1) The typical or average time that the operator will actually be using the tool or tools per day. (Trigger Time) 

2) The level of vibration that the tool is likely to produce while in use, as measured by an approved test authority to the appropriate test norm. Bosch provides data according to EN 60745 wherever possible.

 

Once you have this information, you can quickly and simply identify who, if anyone is at risk (those that work above EAV, or will exceed ELV) and put in place your control measures as required by the directive.
