### STANDARD REVIEW ENGINEERING REPORT P-11-0162 Standard Review Draft 2/24/2011 ENGINEER: Hall \ BCS PV (kg/yr): 280 Revision Notes/Assessment Overview: CEB verified with Technical Contact (Jessica Whiteley) that all of the information contained in initial engineering report is accurate. The contact indicated that none of the information provided in the original submission or initial phone call has changed. SUBMITTER: Esstech, Inc. (submitter) USE: Monomer for adhesives. OTHER USES:

MSDS: Yes LABEL : N o Gen Eqpt: Eng Controls: Use local exhaust at processing equipment, including buffers,| sanders, grinders and polishers. High temperature processing equipment should be well ventilated. // Eyes: safetyl glasses // Hands: Wear chemical resistant gloves for routine industrial use. // Respirator: A respirator is recommended if using at elevated temperatures or under mist forming conditions. Use a N IOSH-approved airpurifying respirator with organic vapor cartridge or canister. Health Effects: Eyes: Liquid and vapors can cause irritation. Symptoms of overexposure may include redness, itching, irritation and watering. // Skin: Liquid or high vapor concentration may cause irritation, including redness and swelling. It may also cause sensitization and allergic reaction in some individuals resulting in contact dermatitis, severe irritation, dryness and cracking. // Inhalation: Is a suspect slight respiratory tract irritation hazard if used at elevated temperatures or processes which generate an aerosol or mist. Symptoms of irritation may include coughing, mucous production and shortness of breath. // Ingestion: May be irritating if product is swallowed; may cause nausea, headache, vomiting, diarrhea, and/or central nervous system effects. TLV/PEL : - none established CRSS: (1/31/2011): Chemical Name: 5-Isobenzofurancarboxylic acid, 1,3-dihydro-1,3-dioxo-, 2-[(2-methyl-1-oxo-2-propen-1-yl)oxy]ethyl ester S-H2O: 0.071 g/L @ VP: 4.3E-6 torr @ MW: 304 0.0%<500 0.0%<1000 Physical State and Misc CRSS Info: Neat: Solid Mfg: Solid Proc/Form: N A End Use: Destroyed. Submitted Data: MP = 95 °C; Flash Point > 93 °C. Estimated Data: BP = 384 °C (EPI), 491 °C (ACD); VP = 4.3E-6 torr (EPI),8.8E -10 torr (ACD); WS = 0.071 g/L (EPI), 0.067 g/L (ACD); logP = 2.84 (EPI), 2.20 (ACD). Consumer Use: SAT (concerns): (2/1/2011 ): Related Cases and Misc SAT Info : N o reasonable analogs were found. Migration to groundwater: Moderate PBT rating: P 1 B 1 T 1
. Health: 2-3, Dermal, InhalationEco: 2, Water (All releases to water with a CC = 20 ppb (methacrylate SAR)) OCCUPATIONAL EXPOSURE RATING: 1-2C NOTES & KEY ASSUMPTIONS: Generated by the 06/07/2005 version of ChemSTEER. This PMN is manufactured domestically; therefore manufacturing and processing as a monomer in adhesive formulations were assessed. // The submitter was contacted. See contact report for details.
