EC Classification Not Classified as Dangerous for Supply/Use. Combustible but not readily ignited. Low toxicity under normal conditions of handling and use.
Substances in the product which may present a health or environmental hazard, or which have been assigned occupational exposure limits, are detailed below. HAZARDOUS INGREDIENT(S) %W/W CAS No. EC No. EC Classification No classifiable hazardous ingredient(s).
Inhalation Remove patient from exposure. Obtain medical attention if ill effects occur. Skin Contact Wash skin with water. If symptoms (irritation or blistering) occur obtain medical attention. Eye Contact Remove particles by irrigating with eye wash solution or clean water, holding the eyelids apart. Obtain medical attention. Ingestion Do not induce vomiting. Wash out mouth with water. Obtain medical attention if ill effects occur. Further Medical Treatment Symptomatic treatment and supportive therapy as indicated.
Combustible but not readily ignited. Combustion or thermal decomposition will evolve toxic, irritant and flammable vapours. By analogy with similar materials, the product may decompose if heated to temperatures above 200��C. Incompatible materials: None known. Extinguishing Media Water spray, foam, dry powder or CO2. Fire Fighting Protective Equipment A self contained breathing apparatus and suitable protective clothing should be worn in fire conditions.

Caution - spillages may be slippery. Sweep up and shovel into waste drums or plastic bags. Wash the spillage area with water.
HANDLING Product as supplied: Avoid contact with eyes. Avoid prolonged skin contact. Unlikely to represent a dust hazard under normal handling conditions. Process Hazards The product may be suitable for a wide range of industrial applications and therefore it is impossible to make detailed recommendations regarding all process hazards. If the product is to be used in applications for which the hazards are not fully understood it is recommended to consult the supplier before use. STORAGE Acrylic polymers are supplied in either bags or bulk containers. Keep containers in a clean, cool and dry area away from heat sources. Natural ventilation is adequate. Storage Temperature Ambient. Specific use Manufacture of objet d'art. Not intended for thermal processing.
Provide adequate ventilation, including appropriate local extraction, to ensure that the occupational exposure limit is not exceeded. Consideration should be given to the work procedures involved and the potential extent of exposure as they may determine whether a higher level of protection is required. The following information is given as general guidance. Respirators A suitable dust mask or dust respirator with filter type P may be appropriate. In the unlikely event of formation of particularly high levels of dust a self contained breathing apparatus may be appropriate. Eye Protection Safety spectacles/goggles/full face shield. Gloves Not normally required. Other Wear suitable protective clothing. For information regarding process hazards refer to Section 7, Handling and Storage.

Hazardous Reactions None known. Hazardous Decomposition Product(s) Methyl methacrylate, Carbon dioxide, Carbon monoxide.
Inhalation Unlikely to be hazardous by inhalation. Skin Contact Unlikely to cause skin irritation. Contains greater than 0.1% residual (Methyl methacrylate). During normal handling this will not constitute a hazard. If the polymer matrix is destroyed e.g. when the product is dissolved in organic solvent, chemical residues will be released from the polymer matrix. Under these conditions, they may produce an allergic reaction in persons already sensitised. Eye Contact Dust may cause irritation. Ingestion Low oral toxicity. Long Term Exposure This type of material has been in use for many years with no evidence of adverse effects.
Environmental Fate and Distribution High tonnage material produced in partially contained systems. Solid with low volatility. The product is essentially insoluble in water. The product has low potential for bioaccumulation. The product is predicted to have low mobility in soil. Persistence and Degradation The product is non-biodegradable in soil. There is no evidence of degradation in soil and water. Toxicity The product is predicted to have low toxicity to aquatic organisms. Effect on Effluent Treatment The material is essentially insoluble in water and can therefore be separated from aqueous medium by sedimentation and filtration processes at an effluent treatment plant.
The waste is considered to be non hazardous. Clean scrap may be reprocessed. Incineration may be used to recover energy value. May be disposed of by landfill in accordance with local regulations. Certain packages are returnable. Please consult your local office for further details. Ensure that all packaging is disposed of safely.
