Potential Health Effects
----------------------------------
Inhalation:
Extremely destructive to tissues of the mucous membranes and upper
respiratory tract. Symptoms may include burning sensation, coughing,
wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
May be absorbed into the body following inhalation with symptoms
paralleling those from ingestion exposure. Dust deposits in the lungs may
resemble a form of pneumoconiosis.
Ingestion:
Corrosive. Swallowing can cause severe burns of the mouth, throat, and
stomach. Can cause sore throat, vomiting, diarrhea. Poison. Symptoms
include pain and burning in the mouth, blackening of the skin and mucous
membranes, throat, and abdomen, salivation, vomiting of black material,
diarrhea, collapse, shock, coma and death.
Skin Contact:
Corrosive. Symptoms of redness, pain, and severe burn can occur.
Eye Contact:
Corrosive. Can cause blurred vision, redness, pain, severe tissue burns and
eye damage.
Chronic Exposure:
Repeated application or ingestion causes a permanent bluish discoloration
of the skin, conjunctiva, and mucous membranes. Repeated inhalation may
cause lung disease.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems or impaired
respiratory function may be more susceptible to the effects of the
substance.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Get medical attention immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never
give anything by mouth to an unconscious person. Get medical attention
immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical attention
immediately. 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.
5. Fire Fighting Measures
Fire:
This oxidizing material can increase the flammability of adjacent combustible materials.
Explosion:
Many reactions may cause explosion. Reacts with ammonia to form compounds
that are sensitive to mechanical shock.
Fire Extinguishing Media:
Use flooding amounts of water. Do not use dry chemical, carbon dioxide or
Halon. Do not allow water runoff to enter sewers or waterways.
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.
6. Accidental Release Measures
Remove all sources of ignition. Ventilate area of leak or spill. Wear
appropriate personal protective equipment as specified in Section 8.
Spills: Clean up spills in a manner that does not disperse dust into the
air. Use non-sparking tools and equipment. Reduce airborne dust and prevent
scattering by moistening with water. Pick up spill for recovery or disposal
and place in a closed container. US Regulations (CERCLA) require reporting
spills and releases to soil, water and air in excess of reportable
quantities. The toll free number for the US Coast Guard National Response
Center is (800) 424-8802.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage and moisture. Isolate from any source of
heat or ignition. Avoid storage on wood floors. Separate from
incompatibles, combustibles, organic or other readily oxidizable materials.
Protect from light. 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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
0.01 mg/m3 (TWA) for silver metal dust and fume as Ag
-ACGIH Threshold Limit Value (TLV):
0.01 mg /m3 (TWA) for soluble silver compounds as Ag
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, a full facepiece respirator with
dust/mist filter 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. 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 impervious protective clothing, including boots, gloves, lab coat,
apron or coveralls, as appropriate, to prevent skin contact.
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.
