Declaration of noise and vibration emission
All values are current as of the date of this publication. For the
latest information please visit cp.com.
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. An EU guide to managing hand-arm
vibration can be found at http://www.humanvibration.com/EU/
VIBGUIDE.htm
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.
