Hi,

I have all the information from the manufacturers of our tools which include the vibration levels, however these are displayed as typical weighted acceleration in the hand arm area, is this just the same rating or do you derive the actual vibration reading from this when looking to get a rough guide to the levels people are exposed to.

Also if anyone has a copy of a vibration assessment they would be willing to let me have a look at that would be very much appreciated.

Regards
Karel

Karel,

use the vibration exposure calculator on the HSE website. If you enter the ratings it will calculate how long each operator can use the tool for. Also, don't rely on the manufacturers readings, they will be taken when the machine is new, under minimal load, in lab type conditions. As soon as you start using the tool, its vibration should, could increase. Many factors may influence this including wear and tear, poor maintenance , wrong tool for job, excessive force, blunt bits etc etc. There's lots of good info on www.operc.com. Most hire companies have adopted a traffic light system to be used as a guide.

The only real way to find out the levels of exposure is to monitor individuals throughout a typical working day using specialist equipment. Having said that the HSE guide is pretty good.
