V.  HEALTH HAZARD INFORMATION 

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of barium ferrite have not been fully investigated and reported

Barium poisoning is virtually unknown in industry, although the potential exists when the soluble forms are used.  When ingested or given orally, the soluble ionized barium compounds exert a profound effect on all muscles and especially smooth muscles, markedly increasing their contractility.  The heart rate is slowed and may stop in systole.  Other effects are increased intestinal peristalsis, vascular construction, bladder contraction, and increased voluntary muscle tension.

Iron compounds have varying toxicity.  Exposure to iron oxides is potentially a serious risk in all industrial settings.  Some iron compounds are suspected carcinogens.  In general, ferrous compounds are more toxic than ferric compounds.  (Sax, Dangerous Properties of Industrial Materials, eighth edition)

Acute Effects:

Inhalation:  May cause irritation of the upper respiratory tract, dizziness, nausea, vomiting, colic, diarrhea, rapid respiration, high blood pressure, irregular heart action, convulsions,  paralysis, acute barium poisoning and possibly acute iron poisoning.

Ingestion:  May cause poisoning, vomiting, colic, diarrhea, slow irregular pulse, transient hypertension, convulsions, tremors, muscular paralysis and acute barium poisoning.

Skin:  May cause irritation.

Eye: May cause irritation and inflammation.

Chronic Effects:

Inhalation:  May cause chronic barium and iron poisoning.

Ingestion:  May cause chronic barium poisoning.

Skin:  May cause dermatitis.

Eye:  May cause corneal opacity and blindness.

Target Organs:  May affect the upper respiratory system, central nervous system, heart, skin and eyes.

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

Carcinogenicity:  EPA:  No     IARC:  No      NTP:  No       OSHA:  No      ACGIH:  No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove to fresh air, keep warm and quiet, give oxygen if there is breathing difficulty.  Seek competent medical attention.

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 and rinse thoroughly.  Seek medical attention if symptoms persist.

EYES:  Flush with copious amounts of lukewarm water, lifting upper and lower eyelids, for at least 15 minutes.  Seek competent medical attention.

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:  Dispose of in accordance with Local, State and Federal Waste Disposal Regulations.

IX.  SPECIAL PRECAUTIONS

Precautionary Labeling:  Warning:  May cause eye irritation.  Harmful by inhalation and if swallowed.

Work 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.
