The graph below shows the vibration value against the maximum time the respective tool
may be used, per day.

The uncertainty factor should
also be taken into account when
assessing a risk. The two figures
‘a’ and ‘K’ may be added together
and the resultant value used to
assess the risk.
It should be noted that if a tool is
used under abnormal, or unusual
conditions, then the vibration
level could possibly increase
significantly. Users must always
take this into account and make

their own risk assessment, using the graph above as a reference.
Some tools with a high vibration value, such as impact wrenches, are generally used for
a few seconds at a time, therefore the cumulative time may only be in the order of a few
minutes per day. Nevertheless, the cumulative effect, particularly when added to that of
other hand held power tools that may be used, must always be taken into account when
the total daily dose rate is determined.
