Potential Health Effects
----------------------------------
Inhalation:
May cause irritation to the respiratory
tract; symptoms may include coughing, sore throat, and shortness of breath. At
high temperatures, exposure to toxic nitrogen oxides decomposition products
can quickly cause acute respiratory problems. Inhalation of large amounts
causes systemic acidosis and abnormal hemoglobin.
Ingestion:
Large oral doses of nitrates may cause dizziness, abdominal pain,
vomiting, bloody diarrhea, weakness, convulsions, and collapse. Harmful if
swallowed. May cause methemoglobinemia resulting in cyanosis.
Skin
Contact:
Causes irritation to skin. Symptoms include redness, itching,
and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Small repeated oral doses of nitrates may
cause weakness, depression, headache, and mental impairment.
Aggravation of Pre-existing Conditions:
No information found.
4. First Aid Measures
Inhalation:
Remove to fresh air. Get medical attention
for any breathing difficulty.
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:
Remove any contaminated clothing. Wash skin with soap and
water for at least 15 minutes. Get medical attention if irritation develops or
persists.
Eye Contact:
Wash thoroughly with running water. Get
medical advice if irritation develops.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong
oxidizer and its heat of reaction with reducing agents or combustibles may
cause ignition. May support combustion in an existing fire.
Explosion:
Contact with oxidizable substances may cause
extremely violent combustion. Sealed containers may rupture when heated.
Sensitive to mechanical impact.
Fire Extinguishing Media:
Use
flooding amounts of water in early stages of fire involving ammonium nitrate.
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
Remove sources of heat and ignition. Collected waste may be
transferred to a closed, preferably metal, container and sent to a RCRA
approved waste disposal facility. Alternatively, sweep spill into
noncombustible container and dissolve in large amount of water. Add soda ash.
Mix and neutralize with 6M-HCl. Neutralized sludge may be sent to an approved
waste disposal facility.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry,
ventilated area. Protect against physical damage. Protect against physical
damage. Store in a dry location separate from combustible, organic or other
readily oxidizable materials. Avoid storage on wood floors. Remove and dispose
of any spilled dichromates; do not return to original containers. Do not store
above 54C (130F) preferably below 30C (86F). 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 protective gloves and clean
body-covering clothing.
Eye Protection:
Use chemical safety
goggles. Maintain eye wash fountain and quick-drench facilities in work area.

12. Ecological Information
Environmental Fate:
When released into the soil, this
material is expected to leach into groundwater. When released into the soil,
this material is not expected to evaporate significantly. When released into
water, this material is expected to readily biodegrade.

Toxicity:
No information found.
13. Disposal Considerations
Whatever cannot be saved for recovery or recycling should be
handled as hazardous waste and sent to a RCRA approved waste 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 container and unused contents in
accordance with federal, state and local requirements.
