for a preliminary assessment of exposure. The data given represents the main applications of the electric
tool. However, if the electric tool is used for different applications, with different accessory tools, or is poorly
maintained, the data may vary. This may significantly increase exposure over the total working period. An
accurate estimation of exposure should also take into account the times when the 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: maintenance of the electric tool and the accessories, keeping the hands warm,
organization of work patterns.
