Declaration of noise and vibration emission
All values are current as of the date of this publication.
These declared values were obtained by laboratory type
testing in accordance with the stated standards and are
suitable for comparison with the declared values of other tools
tested in accordance with the same standards. These
declared values are not adequate for use in risk assessments
and values measured in individual work places may be higher.
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
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.
This tool may cause hand-arm vibration syndrome if its use is
not adequately managed.
We recommend a programme of health surveillance to detect
early symptoms which may relate to noise or vibration
exposure, so that management procedures can be modified
to help prevent future impairment.
