Forallscenarios, skincontaminationwillbethemainroute ofexposuretothenotifiedpolymer.Duringhandlingofthepolymertothenotifiedsolution,thegenerationofmistsleading to possible inhalational exposure is unlikelydue to the highlyviscous nature ofthepolymersolution.However,inhalationalexposuremayoccurduringspraypainting.

LaboratoryDevelopment

Thepolymermanufacture,whencommenced,willinvolve9workersforupto8hoursperday, 10 days peryear.Thereactants and solventswill beadded toanenclosed reactor, andthe resultantpolymer solutionwillbefiltered andfilled into 200L steeldrums. During thefilling process, there is potential for dermal exposure to thepolymer solutionin theform ofdripsandspills.Asthepolymer solutionwillbeviscous,theformationofaerosolsisunlikely.

OccupationalHealthandSafety

There is little potentialfor significantoccupational exposure to thenotifiedpolymer in thetransportandstorageofthe paintcomponentscontainingthispolymer.Therewillbeexposureduringthemanufactureandreformulationofthepolymer,duringthelocalproductionofthepaintcomponents,andintheuseanddisposalofthepaints.

Duringthemanufactureandreformulationprocesses,themainexposurerouteforthenotifiedpolymerwill bedermal.Thepaintsandpolymer solutions will beviscous,andformationofaerosolsisnotexpected.Thepolymerisnotexpectedtobehazardousbydermalexposureas thehighmolecularweightwillprecludeabsorptionthroughtheskin.Protectivemeasuresusedto prevent exposure tothe hazardous solventsshouldprovide sufficientprotection againstthenotifiedchemical.

Thefinalpaintmix,includingthepre-preparedpaintcontainingthenotifiedpolymer,couldcontainawidevarietyofadditionalingredientsoncefullymixed.Thisislikelytointroducehumanhealthhazardsbecause,apartfromarangeofpotentiallytoxicsolvents,otherhazardingredientsmay be present.The spraying procedurealso producesadense aerosol of paintparticleswhichwouldadverselyaffecthumanhealthevenintheabsenceofadditionalhazardouscomponents.It is alsoprobablethatprofessionalsinvolved in thespraypaintingindustrywilluseanumberofdifferentpaintformulations.

Forthese reasons, thenotified polymer mustbe assessedfor the contributionit makes tothehazardsassociated withuseofthespraypaints. Thepresenceofmanypotentialand actualhazardoussubstancesintheformulationsrequirestheuseofstringentengineeringcontrols,suchasacorrectlyconstructed andmaintained spraybooth,andofahighlevelof personalprotectiveequipment,suchasimpermeableoverallsandglovesandafullfaceshieldandrespirator.TheuseofthepaintcontainingthenotifiedpolymershouldbeinaccordancewiththeNOHSCDraftNationalCodeofPracticeforSprayPainting(NationalOccupationalHealthandSafetyCommission,1991).Thelevelofprotectionfromexposureaffordedbythestandardprotective measures willprovide adequate protection fromthenotifiedpolymer,whichislikelytobelessintrinsicallytoxicthanmostofthesolvents,pigmentsandotheringredients.

13.RECOMMENDATIONS

To minimiseoccupationalexposure tothe Polymer inAlkyd Resin HA-1250the followingguidelinesandprecautionsshouldbeobserved:

• Employersshould ensurethatNOHSC exposurestandards forallof thecomponentsofthefinalpaintmixarenotexceededintheworkplace;

• Safetygogglesshould beselectedandfitted inaccordancewithAustralianStandard(AS)1336(StandardsAustralia,1994)tocomplywithAustralian/NewZealandStandard(AS/NZS)1337(StandardsAustralia/StandardsNewZealand,1992);

• IndustrialclothingshouldconformtothespecificationsdetailedinAS2919(StandardsAustralia,1987)andAS3765.2(StandardsAustralia,1990);

• ImpermeableglovesormittensshouldconformtoAS2161(StandardsAustralia/StandardsNewZealand,1998);

• AlloccupationalfootwearshouldconformtoAS/NZS2210(StandardsAustralia/StandardsNewZealand,1994b);

• RespiratorshouldconformtoAS/NZS1715(StandardsAustralia/StandardsNewZealand,1994a);

• Spillage of thenotified chemicalshould be avoided.Spillages should be cleaneduppromptlywithabsorbentswhichshouldthenbeputintocontainersfordisposal;

• Goodpersonalhygieneshouldbepractisedtominimisethepotentialforingestion;

• AcopyoftheMSDSshouldbeeasilyaccessibletoemployees.
