SCHEDULE (Regulations 3 and 4)

Part A. HAND-ARM VIBRATION Assessment of exposure assessment of the level of exposure to hand-arm vibration is based on of the daily exposure value normalised to an eight-hour reference expressed as the square root of the sum of the squares (rms) (total frequency-weighted acceleration values, determined on the orthogonal , as defined in Chapters 4 and 5 and Annex A to ISO standard hwz assessment of the level of exposure may be carried out on the basis of based on information provided by the manufacturers concerning the emission from the work equipment used, and based on the observation of practices or on measurement.

Measurement measurement is employed in accordance with regulation 4(1): methods used may include sampling, which must be representative the personal exposure of a worker to the mechanical vibration in question; the methods and apparatus used must be adapted to the particular characteristics of the mechanical vibration to be measured, to ambient factors and to the characteristics of the measuring apparatus, in accordance with ISO standard 5349-2(2001); the case of devices which need to be held with both hands, measurements must be made on each hand. The exposure is determined reference to the higher value of the two; information for the other hand shall also be given. Interference Regulation 4(4)(d) will apply, in particular where the mechanical vibration the proper handling of controls or reading of indicators. risks

Regulation 4(4)(d) will apply in particular when the mechanical vibration the stability of structures or the security of joints.

Individual protectors Personal protective equipment against hand-arm vibration may contribute to of measures referred to in regulation 5(2).

Part B. WHOLE-BODY VIBRATION Assessment of exposure assessment of the level of exposure to vibration is based on the daily exposure A(8) expressed as equivalent continuous acceleration eight-hour period, calculated as the highest (rms) value, or the highest value (VDV) of the frequency-weighted accelerations, determined on orthogonal axes (1.4a , 1.4a ,a for a seated or standing worker) in wx wy wz with Chapters 5, 6 and 7, Annex A and Annex B to ISO standard 2631-

The assessment of the level of exposure may be carried out an estimate based on information provided by the manufacturers concerning level of emission from the work equipment used, and based on observation specific work practices or on measurement.
