EYES: 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.

SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then dampen the solid spill material with toluene, then transfer the dampened material to a suitable container. Use absorbent paper dampened with toluene to pick up any remaining material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent-wash all contaminated surfaces with toluene 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.

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).

A bioassay of 3-amino-9-ethylcarbazole hydrochloride for possible carcinogenicity was conducted by administering the test chemical in the feed to Fischer 344 rats and B6C3F1 mice. Both the free amine form and the hydrochloride salt were used. Groups of 50 rats of each sex and 50 mice of each sex were admin the test cmpd at one of two doses, either 800 or 2,000 ppm for the rats and either 800 or 1,200 ppm for mice, for 78 wk. The rats were then observed for an additional 26-29 wk, and mice for an additional 16-17 wk. Controls consisted of groups of 50 untreated rats of each sex and 50 untreated mice of each sex; separate controls were used for the groups of animals administered the different doses. All surviving rats were /sacrificed/ at 104-110 wk; all surviving mice were /sacrificed/ at 94-97 wk. ... Under the conditions of this bioassay, 3-amino-9-ethylcarbazole hydrochloride was carcinogenic for the liver, inducing hepatocellular carcinomas in Fischer 344 rats and B6C3F1 mice of both sexes. Other tumors induced in the rats were carcinomas or papillomas of the integumentary system in males, carcinomas of the Zymbal's gland of the ear in males and females, and adenocarcinomas of the uterus. Levels of Evidence of Carcinogenicity: Male Rats: Positive; Female Rats: Positive; Male Mice: Positive; Female Mice: Positive. /3-Amino-9-ethylcarbazole hydrochloride/
