Emergency Overview
Section IV. First Aid Measures
Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,
Eye Contact
keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention.
If the chemical got onto the clothed portion of the body, remove the contaminated clothes as quickly as
Skin Contact
possible, protecting your own hands and body. Place the victim under a deluge shower. If the chemical got
on the victim's exposed skin, such as the hands : Gently and thoroughly wash the contaminated skin with
running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.
Cold water may be used. 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

Remarks
increased incidence of tumors in a number of tissues was seen in rats. No increase in the incidence of
tumors was observed in mice. The strength of the data was evaluated "some", "equivocal", "no" or
"inadequate" evidence of carcinogenicity. Because only a limited response occured, NTP interepreted these
studies as tumor response (e.g.: no effect in mice; some effect in rats)and other concerns about the conduct
of these studies makes it difficult to clearly assess the significance of the results to those who work with MBT.
We recommend that worker exposure to MBT should be minimized.
Mice were given MBT at a dosage of 464 mg/kg by subsutaneous injection on days 6 through 15 of gestion.
In two strains, increased incidences of fetal malformations were noted, but only at maternally toxic doses.
