Exit signs that glow in the dark often contain a radioactive gas called tritium. These signs do not require electricity or batteries and can be used where it is hard to install electrical signs. There are a couple of ways to know whether an exit sign contains tritium. When the lights are off, tritium will make the word EXIT glow green or red. Also, the sign should have a permanent warning label that mentions tritium – radioactive material.
These signs pose little or no threat to public health or safety but proper disposal is required because a damaged sign could contaminate the immediate area and result in expensive cleanup cost.
Midwest Environmental Services can provide safe and secure disposal to those unwanted or end of life signs to meet the complex regulatory requirements. Midwest Environmental Services, with our extensive network of outlets, has the knowledge and resources for proper disposal.
