Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Cold water may be used. Get medical attention if irritation occurs.
Skin ContactWash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation
develops. Cold water may be used.
Serious Skin ContactNot available.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Get medical attention.
Serious InhalationNot available.
IngestionIf swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by
mouth to an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical
attention immediately.

Section 6. Accidental Release Measures
Small SpillDilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal
container. Finish cleaning by spreading water on the contaminated surface and dispose of according to local
and regional authority requirements.
Large SpillStop leak if without risk. Do not get water inside container. Do not touch spilled material. Use water spray to
on disposal. Finish cleaning by spreading water on the contaminated surface and allow to evacuate through
the sanitary system. Be careful that the product is not present at a concentration level above TLV. Check
TLV on the MSDS and with local authorities.

Section 7. Handling and Storage
PrecautionsDo not ingest. Do not breathe gas/fumes/ vapor/spray. Wear suitable protective clothing. If ingested, seek
medical advice immediately and show the container or the label.
StorageKeep container tightly closed. Keep container in a cool, well-ventilated area. Sensitive to light. Store in
light-resistant containers. Product may freeze/crystallize at very cool temperatures. Crystals will redissolve
upon gentle heating.

Section 8. Exposure Controls/Personal Protection
Engineering ControlsProvide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below
their respective threshold limit value.
Personal ProtectionSafety glasses. Lab coat. Gloves (impervious). Respiratory protection is not necessary for normal handling.
Good room ventilation or use of local exhaust (fume hood) is sufficient. Use a vapor respirator under
conditions where exposure to the substance is apparent (e.g. generation of high concentrations of mist or
vapor, inadequate ventilation, development of respiratory tract irritation), and engineering controls are not
feasible. Be sure to use an approved/certified respirator or equivalent.
Personal Protection in Case of Splash goggles. Full suit. Boots. Gloves. Suggested protective clothing might not be sufficient; consult a
a Large Spillspecialist BEFORE handling this product.
TWA: 1 (mg(Fe)/m3) from ACGIH (TLV) [United States]
Exposure Limits
Consult local authorities for acceptable exposure limits.

Section 11. Toxicological Information
Routes of EntryAbsorbed through skin. Eye contact.
Toxicity to AnimalsLD50: Not available.
LC50: Not available.
Chronic Effects on Humans May cause damage to the following organs: blood, kidneys, liver, lymphatic system, pancreas.
Other Toxic Effects onSlightly hazardous in case of skin contact (irritant), of ingestion, of inhalation.
Humans
Special Remarks onNot available.
Toxicity to Animals
Special Remarks onNot available.
Chronic Effects on Humans
Special Remarks on otherAcute Potential Health Effects:
Toxic Effects on HumansSkin: May cause skin irritation, but no adverse effects are expected.
Eyes: Splashes may cause eye irritation.
Inhalation: Vapor may cause respiratory tract irritation.
Ingestion: May be harmful if swallowed. There is a low toxicity in small quantities, but larger doses may lead
to iron poisoning and cause gastrointestinal tract irritation (gastroenteritis) with nausea, retching & vomiting,
abdominal pain, hypermotility, diarrhea, colic or constipation,and black stool. Liver damage and renal failure
have also been reported from iron poisoning. Pink urine discoloration is a strong indicator of iron poisoning.
Iron poisoning may also affect behavior/Central Nervous System (somnolence -general depressed activity,
seizures, irritability, lethargy, restlessness, drowsiness, hyporeflexia, confusion, coma), respiration,
cardiovascular system (weak pulse, hypotension), metabolism (metabolic acidosis), and blood (leukocytosis).
Chronic Potential Health Effects:
Ingestion: Repeated high exposures may lead to iron build-up in the body (particularly in the liver, spleen, and
lymphatic system) causing nausea, vomiting, stomach pain, constipation or diarrhea, black bowel movements,
mild lethargy, irritability, leukocytosis, normocytic anemia, hemochromatosis in the Kupfer cells of the liver or
in the recticuloendothial cells of the bone marrow. Damage may occur to the spleen, lymphatic system, and
liver (cirrhosis, hemsiderosis). Fibrosis or other damage may also occur to the pancreas. Symptoms may
include hypoglycemia, hyperglycemia.
Eyes: Prolonged eye contact may cause brownish discoloration of eyes.
