● ChronicInhalation
EFFECTSOFACUTEEXPOSURETOPRODUCT
SKINDirectcontactmaycauseirritationbymechanicalabrasion.Somecomponentsofmaterialmaycausemild
corrosiveeffectstoskinandmucousmembranes.Skinabsorptionusuallyisnotasignificantrouteofexposure.
EYESDirectcontactmaycauseeyeirritationbymechanicalabrasionwithdiscomfortorpain,localredness,and
swellingoftheconjunctivamayoccur.
INHALATIONIfinhaledintheformofdust,itmaycausenose,throat,andrespiratorytractirritationbymechanicalabrasionor
corrosiveaction.Exposuresinexcessofappropriateexposurelimitsmaycausecoughing,sneezing,chestpain,
shortnessofbreath,inflammationofmucousmembrane,andflulikefevermayoccur.
INGESTIONSmallamounts(atablespoonful)swallowedduringnormalhandlingoperationsarenotlikelytocauseinjury.
Ingestionoflargeamountsmaycausegastrointestinalirritationand/orblockage.Useofmarble,limestone,
onyx,ortravertineforconstructionpurposesshouldnotcauseacutetoxiceffects.However,inhalingrespirable
dustmayaggravateexistingrespiratorysystemdisease(s)and/ordysfunctions.Exposuretodustmayaggravate
existingskinandoreyeconditions.
EFFECTSOFCHRONICEXPOSURETONATURALSTONE
QuartzisanaturalconstituentoftheEarth’scrustandisnotchemicallycombinedwithanyothersubstance.Granite,limestone,
quartzmonzonite,andgranodioritecontain70%to77%silica.Exposuretosilicacontainingdustatanytimeposesapotential
healthhazard.Repeatedoverexposuretoveryhighlevelsofrespirablecrystallinesilica(quartz,cristobalite,tridymite)forperiodsof
sixmonthsormorehavecausedacutesilicosis.Notallindividualswithsilicosiswillexhibitsymptoms(signs)ofthedisease.Acute
silicosisisarapidlyprogressive,incurablelungdiseasethatistypicallyfatal.Symptomscanappearatanytime,evenyearsafter
exposurehasceased.Symptomsinclude(butarenotlimitedto):shortnessofbreath,diminishedworkcapacity,cough,fever,right
heartenlargementand/orfailure,weightloss,andchestpain.Excessiveinhalationofdustmayresultinrespiratorydisease,
includingsilicosis,pneumoconiosis,andpulmonaryfibrosis.Personswithsilicosishaveanincreasedriskofpulmonary
tuberculosisinfection.Smokingmayincreasetheriskofdevelopinglungdisorders,includingemphysemaandlungcancer.
Respirabledustcontainingnewlybrokensilicaparticleshasbeenshowntobemorehazardoustoanimalsinlaboratoryteststhan
respirabledustcontainingoldersilicaparticlesofsimilarsize.
