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: No

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 

NIOSH-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

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.
