ultraviolet radiation if the outer envelope of the lamp is broken or punctured. Do not use where
people will remain for more than a few minutes unless adequate shielding or other safety
precautions are used. Certain lamps that will automatically extinguish when the outer envelope is
broken or punctured are commercially available.
The inner envelope is composed of a ceramic material -- breakage of this envelope may result in
some exposure to elemental mercury, iodine compound vapor, as well as small amounts of
thallium and other iodides. You should avoid skin contact with any of the contents or fragments.
Thallium is not listed as a carcinogen by NTP, IARC, or OSHA. It is a cumulative poison. It or
its salts can be absorbed through intact skin; if they are ingested, they can be absorbed by the
gastrointestinal tract.
Thallium acts as a mitotic (affecting cell division) and a general cellular poison. Acute poisoning
chiefly affects the central nervous system (CNS) and the GI tract. The ingestion of soluble
Thallium salts causes effects rather than the pure metal. Medical conditions aggravated by the
long-term exposure -- disorders of the CNS, GI, kidneys, liver, and eyes.
FIRST AID:
Eyes: Immediately flush eyes, including under the eyelids, gently but thoroughly with
plenty of running water for at least 15 minutes.
Skin: Immediately wash the affected area with soap and water.
Inhalation: Remove the exposed person to fresh air. Restore and/or support his/her breathing
as required.
Ingestion: Treat as an emergency. If the exposed person is responsive, give him or her several
glasses of milk or water -- then induce vomiting.
GET MEDICAL HELP FOR ALL EXPOSURES. While the amount of thallium in the arc tube
is small, avoid breaking lamps. If lamps are to be broken, use adequate personal protection and
ventilation.
