Section 4. First Aid Measures
Eye Exposure: Irrigate eyes at eye wash station for 15 minutes and repeat until pain
free. Seek medical attention if irritation develops or persists, or if visual changes
occur.
Skin Exposure: In case of contact, wash with plenty of soap and water. Seek medical
attention if irritation develops or persists.
Inhalation: If respiratory irritation or distress occurs remove victim to fresh air. Seek
medical attention if irritation develops or persists.
Ingestion: If victim is conscious and alert, give 2-3 glasses of water to drink and on the
advice of medical personnel induce vomiting. Seek immediate medical attention. Do
not leave victim unattended. To prevent aspiration of swallowed product, lay victim on
side with head lower than waist. If vomiting occurs and the victim is conscious, give
water to further dilute the chemical.
Medical conditions possibly aggravated by exposure: none found
Section 5. Fire fighting measures
Extinguishing media: solution is non combustible and non flammable 鈥? product is an
extinguishing agent
Unusual fire/explosion hazards: in a fire this material may decompose, releasing
oxides of carbon (see Section 10).
Insensitive to mechanical impact or static discharge.

HMIS hazard ranking: health 1, flammability 0, reactivity 0
Section 6. Accidental release measures
Large spills (one drum or more) should be addressed by hazardous materials
technicians following a site-specific emergency response plan and trained in the
appropriate use of PPE. Clean up released material using sorbent socks for
containment, followed by sorbent material inside containment. If deemed
necessary,wear full face APR or PAPR with organic vapor cartridges (Section 8). Bag
and drum for disposal. If product is used and/or contaminated use PPE and
containment appropriate to the nature of the mixture. Prevent material from entering
storm sewer. Handle and dispose of as a hazardous waste unless testing indicates
otherwise. Decontaminate with detergent and water.
Section 7. Handling and storage
Store in cool, dry place away from oxidizing agents and wash thoroughly after handling
(see Section 8). Keep product tightly closed in original container or extinguisher. Do
not mix with other extinguishing agents.
Section 8. Exposure controls/ personal protection
During the application of this product against fires, exhaust gases and the products of
incomplete combustion (PICs) are the principal respiratory hazards. In the
manufacture of extinguishers, automated systems and point source ventilation controls
sufficiently minimize respiratory exposure. Employers and employees must use their
collective judgment in determining occupational settings where the use of a respirator
is prudent. The need for respiratory protection is not likely for short-term use in well
ventilated areas.
Respiratory protection: If high concentrations exist, use an approved NIOSH/MSHA
respirator.
Eye protection: wear chemical safety glasses.
Skin protection: use nitrile, rubber, or similar gloves and avoid excessive skin contact.
Wash contaminated skin and clothing thoroughly after handling.
