Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing,
shortness of breath. In severe cases, chemical bronchitis (swelling of air
passages) may result.
Ingestion:
May cause severe irritation to the mouth and throat. Gastrointestinal
disturbances may be expected with nausea, abdominal pain, and vomiting.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain.
Causes burning or serious burns if decontamination is delayed.
Eye Contact:
Causes severe irritation. May cause redness, pain, blurred vision, and eye
damage. Causes burning or serious burns if decontamination is delayed.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Persons with pre-existing lung disease may be more susceptible to the
effects of this 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.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never
give anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of 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.
5. Fire Fighting Measures
Fire:
Not expected to be a fire hazard.
Explosion:
Generation of ammonia gas may be 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.
6. Accidental Release Measures
Ventilate area of leak or spill. Keep unnecessary and unprotected people
away from area of spill. Wear appropriate personal protective equipment as
specified in Section 8. Spills: Pick up and place in a suitable container
for reclamation or disposal, using a method that does not generate dust. 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. Isolate from incompatible substances.
Store below 30C. 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:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures as low as possible. 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):
For conditions of use where exposure to the dust or mist is apparent, a
half-face dust/mist respirator may be worn. For emergencies or instances
where the exposure levels are not known, use a full-face 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.
9. Physical and Chemical Properties
Appearance:
White powder.
Odor:
Strong ammonia-like odor.
Solubility:
Appreciable (> 10%)
Specific Gravity:
1.50 @ 20C/4C
pH:
No information found.
% Volatiles by volume @ 21C (70F):
0
Boiling Point:
No information found.
Melting Point:
58C (136F)
Vapor Density (Air=1):
No information found.
Vapor Pressure (mm Hg):
No information found.
Evaporation Rate (BuAc=1):
No information found.
10. Stability and Reactivity
Stability:
Stable under ordinary conditions of use and storage. Becomes unstable upon
exposure to air and converts into ammonium bicarbonate. This process
liberates ammonia and carbon dioxide.
Hazardous Decomposition Products:
Burning may produce ammonia, carbon monoxide, carbon dioxide, nitrogen
oxides. Contact with water or prolonged contact with air may liberate
ammonia.
Hazardous Polymerization:
Will not occur.
Incompatibilities:
Acids, acid salts, alkaloids, alum, calomel, sodium hypochlorite, iron and
zinc salts, and tartar emetic.
Conditions to Avoid:
Prolonged exposure to air, contact with water, and incompatibles.
11. Toxicological Information
