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.
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.
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.
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.
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.
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
and engineering controls are not feasible, a full facepiece particulate
respirator (NIOSH type N100 filters) may be worn for 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 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.
