Extingu ishing Media: Use dry chemical, CO 2.
Special Fire Fighting Procedures: We ar a self-con tained breathing apparatus and full pro tective clothing to prev ent clo thing to
prevent contac t with skin an d eyes.

Unusual Fire & Explosion Hazard: When hea ted to decom position, copper o xide m ay em it toxic fum es.


V HEALTH HAZARD INFORMATION

Route(s) of Entry: Inhalation, skin, ingestion

Effects of Over Expo sure:

Inhalation: Ma y cau se cough ing, sn eezin g, difficulty b reathing and irritation o f the m uco us m em bran e of the respiratory tract.
Dermal: Ma y cau se irritation , itching , inflam ma tion and d erm itits.
Eye: Ma y cau se bu rning sen sation, irritation, re dne ss and watering of the eyes if com es in co ntact.

Medical Conditions Generally Aggravated by Exposure: Respiratory disorders.
Carcino gencity: None NTP? No IARC M onographs? No OSH A Regulated? No

Other: Copper Compounds: As the sublimed oxide, copper may be responsible for one form of metal fume fever. Inhalation of
cop per d ust has caused, in anim als, hem olysis o f the red blo od cells, dep osition of he mo fuscin in the liv er and pancreas, and inju ry to
the lung cells; injection of the dust has caused cirrhosis in the liver & pancreas, a condition resembling hemochromatosis, or brionzed
diabetes. However, considerable trial exposure to copper compounds has not resulted in such disease.

EMERG ENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 cups of milk or water and induce vomiting. Seek medical attention.
SK IN: Brush off skin, wash area with soap and water and seek medical attention.
EYE: Flush eyes with lukewarm water for 15 minutes and seek medical attention.


VI REACTIVITY DATA

Stability: Stable
Co nditio ns to Av oid: Heat, flam e and in com patible m aterials.
Incompatibility (Materials to Avoid): Peroxyformic acid.

Haz ardous D ecomposition Produc ts: Cu, CuO x fum es.
Hazardous Polymerization: Will not occur.


VII SPILL OR LEAK PROC EDURES

Steps to Be Taken in Case Material Is Released or Spilled: We ar a self-con tained breathing apparatus and full pro tective clothing.
Isolate the are a where the spill occu rred and insure pro per v entilation is available. Vacuum up th e spill using a high efficien cy unit
and place in a co ntainer for proper d isposal. Tak e care not to raise dust.

Waste Disposal Method: In accord ance w ith Loca l, State and Federal W aste Dispo sal Regu lations.


VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type): Wear NIO SH-app roved du st-mist-fume cartridge respirator.
Ventilation: Use local exhaust to maintain exposure below TLV level for Cu. Special: handle in dry, controlled atmosphere.
General exhaust is recommended.

Protective Gloves: Neoprene Eye Protection: Safety Glasses

Other Protective Equipment: Wear protective clothing to p revent contam ination of sk in and c lothes.


IX SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage: We ar pro tective clothing to prev ent co ntam ination of skin and clothes. Store in
tightly closed containe rs in a cool, dry place. W ash han ds and face throu ghly after h andling and b efore m eals.

The abo ve inform ation is believ ed to be co rrect, but do es no t purp ort to b e all inclu sive an d sha ll be used only as a gu ide.
ESPI shall not be held liab le for any d am age resulting from h and ling o r from contact with the abov e pro duc t.
