These declared values were obtained by laboratory type testing in
compliance with the stated standards and are not adequate for use in risk
assessments. Values measured in individual work places may be higher than
the declared values. The actual exposure values and risk of harm experienced
by an individual user are unique and depend upon the way the user works,
the workpiece and the workstation design, as well as upon the exposure time
and the physical condition of the user. We, Chicago Pneumatic, cannot be
held liable for the consequences of using the declared values, instead of
values reflecting the actual exposure, in an individual risk assessment in a
work place situation over which we have no control.
