Notes to Physician: 
Section 5 - Fire Fighting Measures 
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. 
Extinguishing Media: In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. 
Section 6 - Accidental Release Measures 
General Information: Use proper personal protective equipment as indicated in Section 8. 
Spills/Leaks: Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up, then place into a suitable container for disposal. 
Section 7 - Handling and Storage 
Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. 
Storage: Store in a cool, dry place. Keep container closed when not in use. 
Section 8 - Exposure Controls, Personal Protection 
Engineering Controls: 
 Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits. Use process enclosure, local exhaust ventilation, or other engineering controls to control airborne levels. 
Exposure Limits
