Noise levels above 85dB (A) will be experienced at the working position and within a
4-metre radius. Operators and personnel within a 4-metre radius must wear
appropriate ear protection at all times while chipper is in operation to prevent the risk
of hearing damage.
A-weighted emission sound pressure (beside operator’s ear) LpA = 111.7dB(A).
Peak C-weighted instantaneous sound pressure (beside operator’s ear) LCpeak =
136.7dB(C). Results at 10 metre radii are calculated.
As required by Forestry machinery - Wood chippers – Safety BS EN 13525 and in
line with Machinery Directive 2006/42/EC.
