**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Very toxic by inhalation, in contact with skin and if swallowed.
Contact with acids liberates very toxic gas.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts. If absorbed, causes symptoms similar to those of ingestion.
If absorbed, causes symptoms similar to those of inhalation. May be
metabolized to cyanide which in turn acts by inhibiting cytochrome
oxidase impairing cellular respiration.
Ingestion:
May cause irritation of the digestive tract. May cause
gastrointestinal irritation with nausea, vomiting and diarrhea. May
cause tissue anoxia, characterized by weakness, headache, dizziness,
confusion, cyanosis (bluish skin due to deficient oxygenation of the
blood), weak and irregular heart beat, collapse, unconsciousness,
convulsions, coma and death. Ingestion of large amounts of copper
salts may cause bloody stools and vomit, low blood pressure, jaundice
and coma. Ingestion of copper compounds may produce systemic toxic
effects to the kidney and liver and central nervous excitation
followed by depression.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood). May cause respiratory tract
irritation. May cause anoxia, characterized by weakness, headache,
dizziness, confusion, cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), weak and irregular heart beat,
collapse, unconsciousness, convulsions, coma and death. May cause
effects similar to those described for ingestion. Exposure may cause
blood abnormalities. May be metabolized to cyanide which in turns
act by inhibiting cytochrome oxidase impairing cellular respiration.
Chronic:
Repeated exposure may cause central nervous system damage. May be
metabolized to cyanide which in turn acts by inhibiting cytochrome
oxidase impairing cellular respiration. Individuals with Wilson's
disease are unable to metabolize copper. Thus, copper accumulates in
various tissues and may result in liver, kidney, and brain damage.
Chronic copper poisoning in man is recognized in the form of
Wilson's disease. Chronic exposure to cyanide solutions may lead to
the development of a "cyanide" rash, characterized by itching, and by
macular, papular, and vesicular eruptions, and may be accompanied by
secondary infections. Chronic exposure may produce loss of appetite,
headache, weakness, nausea, dizziness, and upper respiratory tract
irritation.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately. Treat patient as for inhalation.
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Remove all contaminated clothing immediately. Treat patient as for
inhalation.
Ingestion:
Do not induce vomiting. Get medical aid immediately. Do not give
anything by mouth. Treat patient as for inhalation.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. Do NOT use mouth-to-mouth resuscitation. Keep warm
and at rest. Administer oxygen. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask. SPEED IS ESSENTIAL, OBTAIN MEDICAL AID
IMMEDIATELY.
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:
Use water spray to cool fire-exposed containers. Do NOT use straight
streams of water. For small fires, use dry chemical, carbon dioxide,
or water spray. For large fires, use water spray, fog or regular
foam.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Do not flush into a sewer. Clean up spills immediately,
observing precautions in the Protective Equipment section. Avoid
generating dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use with adequate
ventilation. Minimize dust generation and accumulation. Do not get
in eyes, on skin, or on clothing. Keep container tightly closed. Do
not ingest or inhale.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep away
from strong acids.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
