Radioactive Tritium Exit Sign DisposalSelf luminous radioactive Tritium H3 exit signs also known as self powered exit signs require special waste disposal services. Radioactive exit signs are sometimes used in facilities such as: skyscrapers / high rises, hospitals, universities, tunnels, airplanes, and office buildings where electrical lines are difficult to run. These self powered exit signs typically use Curie amounts of Tritium (H-3) contained in glass tubes to illuminate the lettering on the exit sign typically in a greenish colored glow.

If you find yourself asking, "What do I do with a radioactive exit sign?" or "How do I dispose of a radioactive exit sign?" remember this, Tritium, while not overly harmful, must be handled properly to avoid Tritium contamination. It is of utmost importance that radioactive exit signs be handled with care to avoid breakage of the glass tubes located inside the exit sign housing containing the Tritium. These signs are to NEVER be thrown away in the regular trash! Let the experts at ADCO Services who have handled the disposal of over 10,000 radioactive exit signs throughout ADCO's history take the hassle out of properly disposing of your radioactive exit signs.

Frequently questions are asked as to what to do with radioactive exit signs during the period of time where the signs have been removed from the wall or ceiling and are awaiting a pickup for disposal. We ask that you place the signs in a secure location where they won't be dropped, bumped (usually in a corner in a box or cabinet), or tampered with by anyone. If you have a sign which is broken, the sign should be handled with Rubber or Latex gloves and placed in a Ziploc bag large enough to safely hold the sign with the bag closed after removing any hardware or mounting brackets that were used to hold the sign on the wall or ceiling, then place the gloves worn to handle the sign inside the bag and seal it. This will reduce chances for Tritium (H-3) contamination. Once the exit signs have been placed in a secure location, call ADCO Services or e-mail: to schedule a pickup.
