If material on fire or involved in fire: Contact the local, state or Department of Energy Radiological Response Team. Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

USE FLOODING AMT OF WATER IN EARLY STAGES OF FIRE. WHEN LARGE QUANTITIES ARE INVOLVED IN FIRE, NITRATE MAY FUSE, OR MELT, IN WHICH CONDITION APPLICATION OF WATER MAY RESULT IN EXTENSIVE SCATTERING OF MOLTEN MATERIAL.

In fire conditions wear self contained breathing apparatus.

Evacuation: If fire becomes uncontrollable, consider evacuation of one half (1/2) mile radius. Keep unnecessary people out of incident area until area declared safe by Radiological Response Team.

PROTECT AGAINST PHYSICAL DAMAGE. STORE IN COOL, DRY PLACE. SEPARATE FROM COMBUSTIBLE, ORGANIC OR OTHER READILY OXIDIZABLE MATERIALS. AVOID STORAGE ON WOOD FLOORS. IMMEDIATELY REMOVE AND DISPOSE OF ANY SPILLED NITRATE.

KEEP WELL CLOSED. /THORIUM NITRATE TETRAHYDRATE/

During transport: Storage temperature: ambient; Venting: open; Stability: stable /Thorium nitrate tetrahydrate/

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Disposal of ... wastes /containing uranium/ should follow guidelines set forth by the Nuclear Regulatory Commission & the EPA. /Uranium & cmpd/

If material not on fire & not involved in fire: Contact the local, state, or Department of Energy Radiological Response Team. Keep sparks, flames, & other sources of ignition away. Keep material out of water sources & sewers.

Personnel protection: Keep upwind. Avoid breathing dusts, & fumes from burning material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap & water.

SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. Contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.

THORIUM NITRATE PRODUCED PROGRESSIVE MORPHOLOGICAL & BIOCHEMICAL ALTERATIONS IN RAT TESTIS WHEN ADMIN DAILY IP. THE DEGENERATIVE CHANGES IN THE SEMINIFEROUS TUBULES INCR WITH THE DURATION OF THE TREATMENT AND AFTER 90 DAYS CALCIFICATION OCCURRED IN ABOUT 25% OF THE TUBULES AND IN THE CONNECTIVE TISSUE OF THE TUNICA ALBUGINEA.

IP ADMIN OF 10 MG THORIUM NITRATE/KG/DAY FOR 120 DAYS TO RATS CAUSED DECREASES IN ALKALINE PHOSPHATASE & ADENOSINE TRIPHOSPHATASE IN THE KIDNEYS AND LIVER.

... One ml doses of 5%, 10%, and 20% thorium nitrate /were applied daily/ to the skin in the lateroabdominal and scrotal areas of male albino rats for 15 days. The animals were sacrified 15 days later. ... There was no gross abnormality in skin, liver, kidneys, or testes of any of the rats. ... Mild degenerative changes were found in the skin and testes of animals receiving the 20% thorium soln. Skin lesions consisted of ... acanthosis & thickening of epithelial lining. Testicular lesions consisted of ... edema of seminiferous tubules & interstitium & desquamation of the spermatogenic cells. A few tubules carried spermatid type giant cells.

Dietary levels of 3% /thorium/ nitrate were required before growth depression occurred in rats; a dog showed growth depression (15%) on 1 g nitrate/kg daily, in a 46-day study.
