4 : PA22-058-0802(R)SDMaterial Safety Data (MSD) sheets forSTYRON* polystyrene resins are availablefrom Dow Plastics, a business group of TheDow Chemical Company and its sheets are provided to help customerssatisfy their own handling, safety, and disposalneeds, and those that may be required bylocally applicable health and safetyregulations. MSD sheets are updatedregularly, therefore, please request and reviewthe most current MSD sheet before handlingor using any following comments are general andapply only to STYRON polystyrene resins additives and processing aids usedin fabrication and other materials used infinishing steps have their own safe use profileand must be investigated and Handling PrecautionsSTYRON polystyrene resins have a very lowdegree of toxicity and under normal conditionsof use should pose no unusual problems fromingestion, eye, or skin contact.

5 However,caution is advised when handling, storing,using, or disposing of these resins and goodhousekeeping and controlling of dusts arenecessary for safe handling of should be protected from thepossibility of contact with molten resin and fabrication of plastic resinscan result in the generation of vapors anddusts. Dusts resulting from sawing, filing, andsanding of plastic parts in post-moldingoperations may cause irritation to eyes andthe upper respiratory tract. In dustyatmospheres, use an approved or beads may present a slippinghazard.

6 Good general ventilation of thepolymer processing area is may release fumes which mayinclude polymer fragments and otherdecomposition products. Fumes can beirritating. At temperatures exceeding melttemperature, polymer fragments can general ventilation should be sufficientfor most conditions. Local exhaust ventilationmay be necessary for some safety glasses. If there is a potentialfor exposure to particles which could causemechanical injury to the eye, wear chemicalgoggles. If vapor exposure causes eyediscomfort, use a full-face respirator.

7 No otherprecautions other than clean body-coveringclothing should be needed for handlingSTYRON polystyrene resins. Use gloves withinsulation for thermal protection, polystyrene resins will burn andonce ignited, may burn rapidly under the rightconditions of heat and oxygen supply. Do notpermit dust to accumulate. Dust layers can beignited by spontaneous combustion or otherignition sources. When suspended in air, dustcan pose an explosion hazard. Dense blacksmoke is produced when product burns. Toxicfumes are released in fire should wear positive-pressure,self-contained breathing apparatus and fullprotective equipment.

8 Water or water fog arethe preferred extinguishing media. Foam,alcohol resistant foam, carbon dioxide, or drychemicals may also be used. Soak thoroughlywith water to cool and prevent NOT DUMP INTO ANY SEWERS, ONTHE GROUND, OR INTO ANY BODY OFWATER. For unused or uncontaminatedmaterial, the preferred options include sendingto a licensed recycler, reclaimer, incinerator, orother thermal destruction device. For used orcontaminated material, the disposal optionsremain the same, although additionalevaluation is required. All disposal methodsmust be in compliance with national, state andlocal laws and speaking, in the environment lostpellets are not a problem except under unusualcircumstances when they enter the marineenvironment.

9 They are inert and benign interms of their physical environmental impact,but if ingested by waterfowl or aquatic life, theymay mechanically cause adverse effects. Spillsshould be minimized and they should becleaned up when they happen.
