For hand-arm vibration the ELV is a daily exposure of 5 m/s 2 A(8). It represents a high risk above which employees should not be exposed. Figure 1 How vibration level and duration affect exposure. The Regulations allow a transitional period for the limit value until July 2010. This only applies to work equipment already in use before July 2007.
The ground vibration may be reduced to the permissible limit by improved blasting pattern, proper selection of delay detonators, proper control over the charge weight, spacing of holes and burden. The vibration reduction with the delay control in blasting is shown in Fig. 13.4a according to which the level of vibration with 25 Ms decreased to 20 per cent that of 50 Ms at 50 m distance.
