Emergency Overview
suspended in air in critical proportions and in the presence of an ignition source may present an explosion
hazard.




Section IV. First Aid Measures
Flush with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids.
Eye Contact


After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated
Skin Contact
skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and
groin. Cover the irritated skin with an emollient. If irritation persists, seek medical attention. Wash
contaminated clothing before reusing.

Allow the victim to rest in a well ventilated area. Seek immediate medical attention
Inhalation


Do not induce vomiting. Immediately give two glasses of water, a little at a time. Never give anything by
Ingestion
mouth to an unconscious person. Call a physician. If vomiting occurs spontaneously, lower head below waist
to prevent fluid from entering the lungs.

Inhalation

Although animal data suggests limited to no acute irritation of this product, occupational exposure has been

reported to cause irritation to the eyes, skin and upper respiratory tract. Allergic skin reactions have also
been reported in skin tests with human subjects.

CARCINOGENIC EFFECTS Not available.
:
Chronic Effects on
MUTAGENIC EFFECTS: CBTS was evaluated in the L5178TK mouse lymphoma mutation assay and in
Humans
microbial mutagenicity assays. The microbial assays used five Salmonella strains, with and without
microsomal activation, and one Saccharomyces yeast strain. No mutagenic effects were demonstrated in any
of these assays.
TERATOGENIC EFFECTS: No teratogenic effects were observed when groups of 25 mated female rats were
treated orally with CBTS at dosages of 100,300, or 500 mg/kg on days 6-15 of gestation. However, a
published study reports an increase in embryonic mortality and a slight decrease in fetal body weight at 2000
mg/kg. Also, 2000 mg/kg of CBTS administered orally to female and male rats prior to mating, caused an
increase in total embryonic mortality with treated females and in untreated females mated with treated males.
