Oral: No known applicable information. Signs and Symptoms of Overexposure No known applicable information. Medical Conditions Aggravated by Exposure No known applicable information. The above listed potential effects of overexposure are based on actual data, results of studies performed upon similar compositions, component data and/or expert review of the product. Please refer to Section 11 for the detailed toxicology information. 4. FIRST AID MEASURES Eye: Immediately flush with water. Skin: No first aid should be needed. Inhalation: No first aid should be needed. Oral: No first aid should be needed. Comments: Treat symptomatically. 5. FIRE FIGHTING MEASURES Flash Point: 212 °F / 100 °C (Closed Cup) Autoignition Temperature: Not available. Flammability Limits in Air: Not available. Extinguishing Media: On large fires use dry chemical, foam or water spray. On small fires use carbon dioxide (CO2), dry chemical or water spray. Water can be used to cool fire exposed containers. Fire Fighting Measures: Self-contained breathing apparatus and protective clothing should be worn in fighting large fires involving chemicals. Determine the need to evacuate or isolate the area according to your local emergency plan. Use water spray to keep fire exposed containers cool.
