When a person uses a two handled tool, the risk is assessed for the individual as being the time on the tool. The person is considered to face the risk of the time and not twice the time despite both hands being used. This is an accepted approach as the hands are independently harmed.
For a singled handed tool, the tool user should use HAVWEAR on the dominant hand. This will then ensure the maximum risk is captured. It is not necessary to also monitor the other hand as like for a two handed tool there is no need to add the exposure of each hand together. If an operator of a one handed tool swaps from their dominant to their non-dominant hand for an extended period of time Reactec advise operators to swap the HAVWEAR device to the non-dominant hand as a precaution
