*SPECIAL PROVISIONS:

*USES:
     This compound is a non-steroid synthetic estrogen used in biochemical research, in medicine (prevents spontaneous abortion) and veterinary edicine.
It is currently approved by the USFDA for the following uses in humans:
(1) replacement therapy of estrogen deficiencies associated with menopause and other hormone-related conditions; (2) control of functional menstrual dis- orders; (3) relief or prevention of breast engorgement after child delivery; and (4) palliative therapy for cancer of the prostate and for cancer of the breast in postmenopausal women.

*COMMENTS:
     Under USDA regulations, no residues are permitted in the tissues of slaughtered animals and it is not permitted in cattle feeds [062].


-HANDLING PROCEDURES
===================

*ACUTE/CHRONIC HAZARDS:
     This chemical may be harmful if swallowed or inhaled.  It may cause irritation of the skin, eyes, mucous membranes and upper respiratory tract. When heated to decomposition it emits toxic fumes of carbon monoxide and carbon dioxide [269].

*MINIMUM PROTECTIVE CLOTHING: Not available

*RECOMMENDED GLOVE MATERIALS:
GlovES+ Expert System Glove Types For The Neat (Undiluted) Chemical:
     This chemical has not been tested for permeation by Radian Corporation;
however, the GlovES+ expert system was used to extrapolate permeation test information from compounds in the same chemical class.  The GlovES+ system uses permeation data from literature sources; therefore, extra safety margins should be used with the estimated protection time(s).  If this chemical makes direct contact with your glove, or if a tear, puncture or hole develops, replace them at once.
     The GlovES+ expert system is a tool that can help people better manage protection from chemicals, however this tool cannot replace sound judgment nor make technical decisions.  Our GlovES+ expert system is designed to offer initial advice and assistance in glove selection while the final glove selection should be made by knowledgeable individuals based on the specific circumstances involved.

Glove Type            Model Number       Thickness   Estimated Protection Time
  Nitrile                   North LA-142G       0.36 mm            480 min
  Unknown              North Silvershield    0.10 mm            480 min
  Viton                    North F-091            0.25 mm            480 min
  Neoprene             Pioneer N-44           0.56 mm            480 min

*RECOMMENDED RESPIRATOR:
     Where the neat test chemical is weighed and diluted, wear a NIOSH- approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid gas, SO2 and a high efficiency particulate filter).

*OTHER:
     Since this chemical is a known or suspected carcinogen you should contact a physician for advice regarding the possible long term health effects and potential recommendation for medical monitoring.  Recommendations from the physician will depend upon the specific compound, its chemical, physical and toxicity properties, the exposure level, length of exposure, and the route of exposure.

*STORAGE PRECAUTIONS:
     You should protect this material from exposure to light, and store it in a refrigerator.

*SPILLS AND LEAKAGE:
     Should a spill occur while you are handling this chemical, FIRST REMOVE
ALL SOURCES OF IGNITION, then you should dampen the solid spill material with 60-70% ethanol and transfer the dampened material to a suitable container.  Use absorbent paper dampened with 60-70% ethanol to pick up any remaining material.
Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal.  Solvent wash all contaminated surfaces with 60-70% ethanol followed by washing with a soap and water solution.  Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

*DISPOSAL AND WASTE TREATMENT: Not available


-EMERGENCY PROCEDURES
====================

*SKIN CONTACT:
     IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing.  Gently wash all affected skin areas thoroughly with soap and water.
     If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment.

*INHALATION:
     IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
IMMEDIATELY call a physician and be prepared to transport the victim to a hospital even if no symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop.
     Provide proper respiratory protection to rescuers entering an unknown atmosphere.  Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Respirator Recommendation.

*EYE CONTACT:
     First check the victim for contact lenses and remove if present.  Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center.
     Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.

*INGESTION:
     DO NOT INDUCE VOMITING.  If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center.  Be prepared to transport the victim to a hospital if advised by a physician.

*SYMPTOMS:
     Symptoms of exposure to this compound via ingestion include dysmenorrhea, premenstrual-like syndrome, amenorrhea (during and after), increase in size of uterine fibromyomata, vaginal candidiasis, change in cervical eversion and of cervical secretion, cystitis-like syndrome; tenderness, enlargement and secretion of the breasts; abdominal cramps, bloating, cholestatic jaundice, chloasma or melasma, erythema multiforme, erythema nodosum, loss of scalp hair, hemorrhagic eruptions, hirsutism, steepening of corneal curvature, intolerance to contact lenses, headache, migraine, dizziness, mental depression, chorea, decrease or increase in weight, reduced carbohydrate tolerance, aggravation of porphyria, edema and changes in libido [072,157].  Gynaecomastia is the main side effect in the male.  Exposure may also cause proliferation and withdrawal bleeding, sodium retention, nitrogen retention, alterations in liver function, jaundice, nausea and vomiting [295].  It can cause male impotence and transsexual changes [029].  It may also cause congenital malformation in the fetus [269].  Human reproductive effects by ingestion include abnormal spermato-genesis, changes in the testes, epididymis and sperm duct; menstrual cycle changes or disorders, changes in female fertility, developmental abnormalities of the fetal urogenital system, germ cell effects in offspring and delayed effects in the newborn [043].
