IV.   FIRE AND EXPLOSION HAZARDS DATA

Extinguishing Media:  Terbium nitrate is a strong oxidizer and its heat of reaction with reducing agents or combustibles may cause ignition.  Use water, carbon dioxide, dry chemical extinguishing agents, dry sand, or dry ground dolomite.

Special Fire Fighting Procedures:  No special firefighting procedures needed.  Use normal procedures which include wearing NIOSH/MSHA approved self-contained breathing apparatus, flame and chemical resistant clothing, hats, boots and gloves.  If without risk, remove material from fire area.  Cool container with water from maximum distance.

Unusual Fire & Explosion Hazard:  None

V.   HEALTH HAZARD INFORMATION

Animal Toxicology:  LD50:  No data       LC50:  No data    Other:  No data

Most Likely Routes of Entry:  Ingestion.

Medical Conditions, If Any, Aggravated by the Chemical:  None known.

Effects of Over Exposure:

Acute Effects:

Ingestion:  Large amounts of nitrates taken by mouth may have serious or even fatal results.  The symptoms are dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, convulsions and collapse.

Skin Contact:  May cause irritation.

Eye Contact:  May cause irritation.

Inhalation:  May cause irritation.

Other Health Hazards:  May cause delayed blood clotting leading to hemorrhages.

Chronic Effects:

Ingestion:  Small, repeated doses of nitrates may lead to weakness, general depression, headache and mental impairment.  There is also some implication of increased cancer incidence among those exposed.

Skin Contact:  None known

Eye Contact:  None known

Inhalation:  None Known

Other:  Nitrates can interact with amines to form nitrosamines, which are carcinogenic in animals.

EMERGENCY AND FIRST AID PROCEDURES:

INGESTION:  No data available but one should obtain medical attention.

SKIN:  Remove contaminated clothing, flood skin with large amounts of water.  If irritation persists seek medical attention.

EYES:  Immediately flush eyes, including under eyelids, with large amounts of water for at least 15 minutes.  Call a physician.

INHALATION:  No specific information available, one should obtain medical attention.

VI.   REACTIVITY DATA

Incompatibilities:  Mineral acids, reducing agents, organic material.

Hazardous Decomposition Products:  No data

Hazardous Polymerization:  Will no occur

Conditions to Avoid:  Incompatibles

Stability:  Stable

Other:  Oxidizing agents may cause ignition when in close contact with organic material or reducing agents.  Nitrates may explode when shocked, exposed to heat or flame or by spontaneous chemical reaction.

VII.   SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material is Released or Spilled:  Wearing full protective equipment, cover spill with dry sand or vermiculite.  Mix well and carefully transfer to a container.

Waste Disposal Method:  Consult State, Local or Federal EPA regulations for proper disposal.
