V HEALTH HAZARD INFORMATION

Routes of Entry: Inhalation, Skin, Eyes, and Ingestion

Health Hazards (Acute and Chronic):

To the best of our knowledge the chemical, physical and toxicological properties of iron phosphide have not been thoroughly
investigated and recorded.

Iron compounds have varying toxicity. Some iron compounds are suspected carcinogens. In general, ferrous compounds are
more toxic than ferric compounds. Acute exposure to excessive levels of ferrous compounds can cause liver and kidney damage,
altered respiratory rates and convulsions (Sax, Dangerous Properties of Industrial Materials, eighth edition).

Inhalation: Acute: Inhalation of dust or powder may cause irritation to the respiratory system and possibly acute iron poisoning.
Large amounts of iron may cause iron pneumoconiosis.
Chronic: Inhalation of finely divided powder may cause pulmonary fibrosis. May cause chronic iron poisoning and pathological
deposition of iron in the body tissue.

Ingestion: Acute: No acute health effects recorded.
Chronic: May cause damage to the liver.

Skin: Acute: May cause irritation.
Chronic: No chronic health effects recorded.
Eyes: Acute: May cause irritation.
Chronic: No chronic health effects recorded.

Target Organs: May affect the liver and kidney.
Carcinogenicity: NTP? No, IARC? No, OSHA Regulated? No

Recommended Exposure Limits: See Section II
LD50/LC50: No toxicity data recorded.

Signs and Symptoms of Exposure:

Inhalation: May cause a red, dry throat and coughing. Acute iron poisoning may cause: biphasic shock, rapid increase in respiration
and pulse rate, congestion of blood vessels which may lead to hypotension, pallor and drowsiness. Chronic iron poisoning may cause:
hemorrhagic necrosis of the gastrointestinal tract, hepatotoxicity, metabolic acidosis, prolonged blood clotting time, elevation of
plasm levels of serotonin and histamine. Symptoms of pathological deposition or fibrosis of the pancreas, diabetes,
mellitus and liver cirrhosis.

Ingestion: No acute or chronic health effects recorded.
Skin: May cause redness and itching.
Eye: May cause redness, itching and watering.

Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention if
symptoms persist.
INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention. Never induce vomiting or give
anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention
if symptoms persist.
EYES: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms
persist.

VI REACTIVITY DATA

Conditions to Avoid: None

Incompatibilities (Materials to Avoid): None recorded
Hazardous Decomposition Products: Oxides of Phosphorus
Conditions to Avoid: None

VII SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in
Section VIII. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter
and place in a closed container for proper disposal. Take care not to raise dust.

Waste Disposal Method: Disposal must be made in accordance with Federal, State and Local regulations.
VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type): NIOSH approved Dust, mist, vapor respirator
Ventilation: Local Exhaust: To maintain concentration at or below the PEL, TLV.
Mechanical: Recommended. Special: None Other: None

Protective Gloves: Rubber Gloves Eye Protection: Safety Goggles
Other Equipment: Normal lab wear suitable to prevent contamination.

Work/Hygienic/Maintenance Practices: Implement engineering and work practice controls to reduce and maintain concentration of
exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly
before eating and smoking. do not blow dust off clothing or skin with compressed air.

IX SPECIAL PRECAUTIONS

Some of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various
governmental regulations. In accordance with Environmental Protection Agency regulation and the Toxic Substances Control Act
(TSCA), these materials should only be handled by, or under the direct supervision of, a ??technically qualified individual??, as defined
in 40 CFR 710.2(aa).
