Hi All,
I am currently undertaking vibration assessments at our manufacturing premises. For one of the procedures, I have collected data on the electrical tools the guys are using, which is a grinder and a magnetic drill and completed a time & Motion study to ascertain trigger times.
The question I have is what calculation should be allowed for somebody marking out using a dot-punch and hammer.

I would suggest 'none' but if you are going to try, then the 'calculation' is the same as for other situations - vibration level 'x' exposure time. How you measure the first is anybodies guess and the latter is something of an 'instant'.
It will be interesting to hear others thoughts but I personally am not convinced that you need to and would be intrigued about how you would go about it.

Dot punch & hammer - Not a vibrating tool, so IMHO, not covered by the regs, so no need to calculate.

As Cerith says "not a vibration issue"!
However, you probably do have an ergonomic issue and a possible acute and chronic soft tissue and bone degradation issue that require consideration.

Thanks Guys
You have confirmed what I thought.
One of our directors was insisting that it should be included within the calcs for the daily exposure. My argument was the levels would change depending on how hard they hit the dot-punch.
