7.5 NoiseReductionFactors
Toreduceriskfromexposuretonoise:
n Useapprovedearprotectorsorplugs.RefertoEUguide,EN458.
n Carryoutregularmaintenanceonearprotectors.Forexample,replaceearprotector
sealseverysixmonths.
n Usehelmetgogglesifusingearprotectorsoruseearplugswhenusinggogglesor
spectacles,asgogglesandspectacleswillreducetheeffectofearprotectors.
n Makesuretheearplugsfitcorrectly.Theincorrectsizeofearplugsreducesthedamp
ingeffect.
n Performregularmaintenanceofdoorandcabinseals,insulationandmufflers
n Workwiththecabindoorandwindowsclosed
7.6 NoiseCombinedwithOtherRiskFactors
Noise,incombinationwithotherriskfactorscancauseserioushealthissues.
n Vibrationandnoiseincombinationcancausehigherhealthrisks.
n Peoplewithsensitiveconditions(forexample,pregnancy)andpeoplealreadywithim
pairedhearingmayneedprotectionagainstnoiseevenatlowerlevels.
n Exposuretoototoxicsubstancesandnoisemayincreasetheriskofhearingdamage
(evenunder80dB).Forexample;styrene,tolueneandxylene,andcertainsolvent
mixturesareototoxic.Certainfuelssuchaskeroseneandcertainmetalssuchasmer
curyandlead,havealsobeenproventobepotentiallyototoxic.
7.7 FactorsAffectingWholeBodyVibration
Thefollowingfactorsmayaffectwholebodyvibration:
n Trammingforlongerduration.
n Speed,dutycycleandgroundconditionswhileoperatingfromacabin.Thesefactors
areprimarilyinfluencedbytheoperatorwhocontrolsforexamplespeed,workingcy
cle,androuteoptions.
7.8 VibrationReduction
n Donotexposethemachinetohigherloads,speedsorperformancefactorsthanspeci
fied.Excessiveloadsandmechanicalwearincreasesvibration.
n Usethemachinecorrectlytogetherwithrelatedequipmentrequiredforthetask.Use
ofincorrectequipmentcancauseincreasedvibrations.
n Usingremotecontrolcanreducevibrations.
n Avoidlargeholesandunevengroundwhentramming.Adaptthespeedtothetram
mingconditionstoreducevibrations.
