Exposure calculation by using emission data with a step-by-step procedure of risk assessment

⁽¹⁾ The selected tools will be used to calculate the exposure in the recurring working day at maximum risk at point 2. The other tools must be listed anyway for the purposes of the survey of the processes involved and the machinery and equipment used

Identification of the recurring working day at maximum risk (RWDMR). If the preceding step highlights the existence of a relevant risk it is necessary to identify the recurring conditions at maximum risk in order to define the worst day of exposure to vibration occurred in the preceding year and that can be reasonably expected in the following years. The unusual daily exposure conditions that, on the whole, do not exceed 2 days/year can be excluded. The RWDMR is the day that must be examined in order to identify the performed activities (with the related ahv values) and their duration in order to define the A(8) for every single worker, for recurring working days.

2) Identification of the vibration levels ahv [m/s2] and the related times of exposure in the recurring working day at maximum risk (RWDMR). What are the worst conditions of exposure (sources/working practices) in the RWDMR? Enter the identified conditions in the following tool:

WORKING CONDITION Type, Brand, Model	Vibration level ahv m/s2	TIME OF EXPOSURE in the recurring working day at maximum risk [hours]	PARTIAL DAILY EXPOSURE A(8)
