Seek medical attention as required.
Phosphor –There have been no significant adverse effects on humans by ingestion, inhalation, skin contact, or eye
contact. Antimony, manganese, yttrium and tin compounds are characterized by OSHA as hazardous chemicals;
however, due to their insolubility, relatively low toxicity and small amount present in the phosphor and lamp,
these materials do not present a significant hazard in the event of breakage of the lamp.
Yttrium –Contact, ingestion or inhalation may cause one or more of the following symptoms: eye irritation,
pulmonary irritation, and possible liver damage.
Aluminum Oxide (Alumina) – Alumina is a non-toxic material which is very low in free silica content. Sharp-edged
particles can irritate the eyes, perhaps the skin, and definitely the mucous membranes of the respiratory tract.
Krypton-85 Contained in Glow Switch – The radiation emitted by Kr-85 is 99.6% beta which is completely
absorbed by the glass envelope of the glow switch and 0.4% gamma which is not. This radiation is, however, 100
to 200 times less than that allowable for clocks and watches. In the unlikely event of the glow switch breaking, the
traces of krypton-85 gas immediately disperses in the air. Krypton gas and its radioactive isotope are inert (they do
not react chemically with other substances) and are not absorbed by the body.
