Cupric Oxide 1317-38-0 100% Yes
Inhalation: Causes irritation to respiratory tract, symptoms may include
coughing, sore throat, and shortness of breath. May result in ulceration and
perforation of respiratory tract. When heated, this compound may give off copper
fume, which can cause symptoms similar to the common cold, including chills and
stuffiness of the head.
Ingestion: Systemic copper poisoning may result from ingestion of this
compound. Symptoms may include capillary damage, headache, cold sweat, weak
pulse, kidney and liver damage, central nervous excitation followed by
depression, jaundice, convulsions, blood effects, paralysis and coma. Death may
occur from shock or renal failure.
Skin Contact: Causes irritation, redness, pain.
Eye Contact: Causes irritation with redness, pain. May cause eye damage.
Chronic Exposure: Prolonged or repeated skin exposure may cause
dermatitis. Prolonged or repeated exposure to dusts of copper salts may cause
discoloration of the skin or hair, blood and liver damage, ulceration and
perforation of the nasal septum, runny nose, metallic taste, and atrophic
changes and irritation of the mucous membranes.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin
disorders, impaired liver, kidney, or pulmonary function, glucose
6-phosphate-dehydrogenase deficiency, or pre-existing Wilson's disease may be
more susceptible to the effects of this material.
Inhalation: Remove to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen. Call a
physician.
Ingestion: Induce vomiting immediately as directed by medical personnel.
Never give anything by mouth to an unconscious person. Call a physician
immediately.
Skin Contact: In case of contact, wipe off excess material from skin then
immediately flush skin with plenty of water for at least 15 minutes. Remove
contaminated clothing and shoes. Wash clothing before reuse. Call a physician.
Eye Contact: Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get medical attention
immediately.
Fire: Not considered to be a fire hazard. Large
masses exposed to moist air at over 100C can result in spontaneous combustion.
Explosion: Not considered to be an explosion hazard. Reactions with
incompatibles may pose 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.
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Airborne Exposure Limits: -OSHA Permissible Exposure
Limit (PEL):1 mg/m3 (TWA) for copper dusts & mists as Cu
-ACGIH Threshold Limit Value (TLV):1 mg/m3 (TWA) for copper dusts & mists as Cu
Ventilation System: A system of local and/or general exhaust is
recommended to keep employee exposures below the Airborne Exposure Limits. Local
exhaust ventilation is generally preferred because it can control the emissions
of the contaminant at its source, preventing dispersion of it into the general
work area. Please refer to the ACGIH document, Industrial Ventilation, A
Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded
and engineering controls are not feasible, a half facepiece particulate
respirator (NIOSH type N95 or better filters) may be worn for up to ten times
the exposure limit or the maximum use concentration specified by the appropriate
regulatory agency or respirator supplier, whichever is lowest.. A full-face
piece particulate respirator (NIOSH type N100 filters) may be worn up to 50
times the exposure limit, or the maximum use concentration specified by the
appropriate regulatory agency, or respirator supplier, whichever is lowest. If
oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present,
use a NIOSH type R or P filter. For emergencies or instances where the exposure
levels are not known, use a full-facepiece positive-pressure, air-supplied
respirator. WARNING: Air-purifying respirators do not protect workers in
oxygen-deficient atmospheres.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where
dusting or splashing of solutions is possible. Maintain eye wash fountain and
quick-drench facilities in work area.

granules, or wire.
