An accurate estimation of exposure should also take into account the times when the power tool is switched
off, or when it is running but not actually being used for a job. This may significantly reduce exposure over
the total working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: Maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.
