Proper Tritium Dispoal

Just as there is a right and wrong way to dispose of a computer. There is also a right and wrong way to dispose of Tritium signs. The most familiar tritium signs are exit signs found in building that leads a person to safety in the event of an emergency. Because of the important job these signs have been given, they must work properly, be inspected regularly, and be reported to a government entity of all their whereabouts. This task may seem taxing and in some cases minuscule to the laymen. However, constructions companies and facility manager/owner must adhere to the government guidelines on proper Tritium disposal.


What is Tritium?

Tritium is a gas that is comprised of two neutrons and one proton and is minimally radioactive. Although Tritium is a low-level radioactive beta emitter, there are still federally mandated rules to handle, the transfer and disposal of this material.

Who can dispose of Tritium?

One must be appointed a “responsible individual” in order to properly handle this type of disposal. The device should be checked every five years as they have a 10-12.5 year life span. Many companies return the Tritium sign to the manufacture for disposal. However, if you choose to have a person in-house to dispose of the Tritium sign, you must list him or her with your regional Nuclear Regulatory Commission (NRC). Find your local NRC.
