Emission values
Using these values, you can estimate the
emissions from this tool and compare these with the
values emitted by other tools. The actual values
may be higher or lower, depending on the particular
application and the condition of the tool or mounted
tool. In estimating the values, you should also
include work breaks and periods of low use. Based
on the estimated emission values, specify protec-
tive measures for the user - for example, any organ-
isational steps that must be put in place.
