Potential Health Effects
---------------------------
Inhalation:
Inhalation of dusts and fumes of metallic copper causes
irritation of the upper respiratory tract, congestion of nasal
mucous membranes, ulceration and perforation of the nasal
septum, and pharyngeal congestion. Inhalation of copper fumes
may give rise to metal fume fever (high temperature, metallic
taste, nausea, coughing, general weakness, muscle aches, and
exhaustion).
Ingestion:
Copper ingestion causes nausea, vomiting, abdominal pain,
metallic taste, and diarrhea. Ingestion of large doses may cause
stomach and intestine ulceration, jaundice, and kidney and liver
damage.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching,
and pain. Exposure to copper dust may cause a greenish-black
skin discoloration.
Eye Contact:
Small copper particles in the eyes may cause irritation,
discoloration, and damage.
Chronic Exposure:
Prolonged or repeated exposure to copper can discolor skin and
hair and irritate the skin; may cause mild dermatitis, runny
nose, and irritation of the mucous membranes. Repeated ingestion
may damage the liver and kidneys. Repeated inhalation can cause
chronic respiratory disease.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or impaired liver,
kidney, or pulmonary function or pre-existing Wilson's disease
may be more susceptible to the effects of this material. |

First Aid Measures |
|
Inhalation:
Remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical
attention.
Ingestion:
Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person.
Skin Contact:
Immediately flush skin with plenty of soap and water for at
least 15 minutes. Remove contaminated clothing and shoes. Get
medical attention. Wash clothing before reuse. Thoroughly clean
shoes before reuse.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get
medical attention immediately. |
4.
Fire Fighting Measures |
|
Fire:
Not considered to be a fire hazard since the bulk solid does not
burn, but very finely divided particles (ultra-fine powder) may
burn in air.
Explosion:
Not considered to be an explosion hazard. Reactions with
incompatibles may pose an explosion hazard. Liquid copper
explodes on contact with water. High concentrations of finely
divided copper particles in the air may present an explosion
hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full facepiece operated
in the pressure demand or other positive pressure mode. |
5.

managed in an appropriate and approved waste disposal facility.
Processing, use or contamination of this product may change the
waste management options. State and local disposal regulations
may differ from federal disposal regulations. Dispose of
