WBV – Whole Body Vibration: HAV – Hand-Arm Vibration: There is no predefined measurement time; the measurement time is variable! What does NHO 09 say? 6.7.4 Interpretation of the result obtained (...) It is important to emphasize that the selection of the number of measurement repetitions in the evaluation procedure of the identified exposure components, as well as the duration of the measurement time, integral or partial, in the quantification of the amrik and VDVjik parameters, in each measurement repetition, DEPENDS ON THE ANALYSIS AND JUDGMENT OF THE EVALUATOR. The evaluator should always seek the alternative that, in their technical conviction, best represents the exposure conditions of the worker under study. What does NHO 10 say? 6.7.3.1 Interpretation of the result obtained (...) It is important to emphasize that the selection of the number of measurement repetitions in the evaluation procedure of the identified exposure components, as well as the duration of the measurement time, integral or partial, in the quantification of the amrik and amijk parameters, in each measurement repetition, DEPENDS ON THE ANALYSIS AND JUDGMENT OF THE EVALUATOR. The evaluator should always seek the alternative that, in their technical conviction, best represents the exposure conditions of the worker under study. So, how long should a vibration measurement last? The vibration measurement can last the TOTAL duration of each Exposure Component; or The vibration measurement can last a PORTION of the total duration of each Exposure Component. What is a Vibration Exposure Component? According to NHOs 09 and 10, Exposure Components are: Exposure component: part of the daily exposure that can be represented by a single value of the resultant acceleration of partial exposure (arep). The exposure component can result from a single operation or be a consequence of two or more operations performed sequentially. Practical Example: In summary: There is no standard time for a vibration measurement; the duration of the vibration measurement is always variable; According to NHOs 09 and 10, the duration of vibration measurement should cover the total duration of the component or a partial duration of the component; Preferably measure the total duration of the component; When measuring only a portion of the total duration of the component, try to determine the time in which you can capture all possible vibration variations that may occur during the execution of that evaluated component; It is almost impossible to determine the vibration measurement time without knowing the worker's and/or company's activity. ____ Watch the video, leave your comment for or against, and we will be happy to discuss the subject.
