Thedeclaredvaluesarenotadequateforuseinriskassessments,asvaluesmeasuredin
individualworkplacesmaybehigher.
Theactualnoiselevelsandvibrationvaluestowhichanindividualisexposedtoareunique
anddependentontheworkpractices,reflectionsfromwalls,roadconditions,durationof
exposuretimeandthephysicalhealthoftheindividual.
Incorrectuseofthemachinecancausehealthproblemsduetowholebodyvibrationand

AtlasCopcorecommendsaprogramofhealthsurveillancetodetectearlysymptoms
causedbyexposuretonoiseandvibrations,sothatmanagementprocedurescanbemodi

ThenoiseemissionvalueshavebeendeclaredusingEN4871.
7.2 DeclaredValues
n Thedeclaredvaluesfornoiseandvibrationwereobtainedbytestinginaccordance
withthestatedstandardsandarecomparablewiththedeclaredvaluesofotherma
chinestestedinaccordancewiththesamestandards.
n Thedeclaredvaluesarenotadequateforuseinriskassessments,asvaluesmea
suredinindividualworkplacesmaybehigher.
n Theactualnoiselevelsandvibrationvaluestowhichanindividualisexposedtoare
uniqueanddependentontheworkpractices,reflectionsfromwalls,roadconditions,
durationofexposuretimeandthephysicalhealthoftheindividual.

tualexposurevaluesinanindividualriskassessment.
n Incorrectuseofthemachinecancausehealthproblemsduetowholebodyvibration
andnoise.AnEUguideonthemanagementofvibrationisavailableinISO/TR25398

7.3 CausesofHighNoiseLevels
Noiselevelshigherthanthestatedvaluesarelikelytooccurwhen:
n Workingunderground
n Incorrectlyusingthemachine
n Workingwithincreasedloadwhencomparedtospecifiedvalues
n Usingcompressedair
7.4 EffectsofNoise
Exposuretonoisecanresultinadversehealtheffects,suchas:
n Permanenthearingloss
n Tinnitus
n Fatigueandstress
n Balanceissues
n Poorattention
