Potential Health Effects
----------------------------------
Inhalation:
Causes irritation to the respiratory tract.
Symptoms may include coughing, shortness of breath.
Ingestion:
Low toxicity in small quantities but larger dosages may cause nausea,
vomiting, diarrhea, and black stool. Pink urine discoloration is a strong
indicator of iron poisoning. Liver damage, coma, and death from iron poisoning
has been recorded. Smaller doses are much more toxic to children.
Skin
Contact:
Causes irritation to skin. Symptoms include redness, itching,
and pain.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Severe or chronic ferrous sulfate poisonings
may damage blood vessels. Large chronic doses cause rickets in infants.
Chronic exposure may cause liver effects. Prolonged exposure of the eyes may
cause discoloration.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin disorders or eye problems, or impaired
liver, kidney or 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.
Ingestion:
Induce vomiting immediately as directed
by medical personnel. Never give anything by mouth to an unconscious person.
Get medical attention.
Skin Contact:
Immediately flush skin
with plenty of soap and 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 considered to be a fire hazard.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for
extinguishing surrounding fire.
Special Information:
Use
protective clothing and breathing equipment appropriate for the surrounding
fire.
6. Accidental Release Measures
Ventilate area of leak or 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. Maintain a constant
temperature not to exceed 24 degrees centigrade (75 degrees fahrenheit).
Fluctuating temperatures causes product oxidation. Do not use this product if
coated with brownish-yellow basic ferric sulfate. 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.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-ACGIH Threshold Limit Value
(TLV):
1 mg/m3 (TWA) soluble iron salt as Fe
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
half-face dust/mist respirator 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
dust/mist respirator 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.

forming a brown coating of extremely corrosive basic ferric sulfate.
Hazardous Decomposition Products:
Burning may produce sulfur
oxides.
Hazardous Polymerization:
This substance does not
polymerize.
Incompatibilities:
Alkalis, soluble carbonates, and
oxidizing materials. Reacts in moist air to form ferric sulfate.
Conditions to Avoid:
Moisture.
