APPENDIX "B"
Air noise (DIRECTIVE 2006/42/EC, Annexe 1, point 1.7.4.2, letter "u"):
– The continuous equivalent weighted level (A)
of noise pressure at the working place L
– The maximum value of instantaneous weighted noise
pressure C at the working place L
– The level of noise force produced by the machine L
is equal to..................................................................................................... 96,6 dB (A)
Protection of operators against risksof exposure to noise during work.
Cembre drills type LD-2EY are designed and constructed according to EEC directives
80/1107 and 86/188 relating to the protection of operators against risks arising from ex-
posure to chemical, physical and biological agents during work, and with particular regard
to the risk of exposure to noise.
This has enabled a range of drills to be manufactured for drilling rails and track equipment,
at reduced noise levels.
The degree of exposure of an operator to noise produced from this equipment depends
on the duration of the loading times and the intervals between exposures, and fi nally on
the number of holes made within the space of one working day.
For example, an operator using the drill correctly for making holes 19 mm in diam., with
a type RCV 190 broach cutter on rails classifi ed as UIC 60, quality 900, producing up to
400 holes/day, the daily personal exposure to noise, due solely to the use of the drill, is
less than 80 dB (A); under similar conditions producing 700 holes/day, the daily exposure
to noise would be 82.1 dB(A).
Since noise levels vary according to the many different operating conditions, Cembre
engineers are available to give further details on the correct use of the drills.
Risks due to vibration (Directive 2006/42/EC, Annexe 1, point 2.2.1.1).
The weighted root mean square acceleration value to which the arms of an operator are
subjected when using the drill machine does not exceed 2,5 m/s
