Exposure calculation by using emission data

Determine if there is a relevant vibration-related risk

Verify if the kind of production/service of your firm underlines the absence of risks or exposure values below 0,2 m/s² by observing the working practices and/or by referring to data in the literature or in vibration databases, to data declared by the manufacturer or to instrumental measures.

1) Does the production/service of your firm is such to place it among those firms whose working practices do not entail a relevant risk of exposure to Whole-Body Vibration?

Yes No

NO RELEVANT RISK
(it is not necessary to determine the A(8) for the operators)
END OF THE PROCEDURE

Identification of the machines and of the working practices that transmit, according to the judgement of the evaluator, the highest vibration to the whole body.

MACHINERY type, brand, model	WORKING CONDITION e.g. ploughing, transportation...	Select to assess the risk (1)	Click to remove

⁽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). After this identification step, you can proceed to the characterization of 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 avmax 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 awmax [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 a_wmax m/s²	TIME OF EXPOSURE in the recurring working day at maximum risk [hours]	PARTIAL DAILY EXPOSURE A(8)
