Any building, in any industry, in any area of the world, is susceptible to having potentially hazardous and radioactive exit signs installed throughout their building.

This could mean they are in schools, near your office, or anywhere else where a radioactive setting probably isn’t a desired situation to be in.

This is why we thought it was necessary to create this post to help and guide you towards identifying, removing, and finally replacing your radioactive exit signs with new signs that are much safer and even efficient, saving you money over other alternatives.

Firstly before we can remove and replace these seemingly nuclear exit signs, you have to be able to identify if you have them or not. But before that, lets explain what exactly makes these exit signs radioactive.

How are some exit signs radioactive?

Just the same way as some exit signs are safe, it is all in the way they are built. For some reason, whether it be technology of the time or something else, people assumed it was a good idea to create exit signs with Tritium, also known as 3H or H-3. Tritium is a radioactive isotope of hydrogen, causing exit signs made with this to be radioactive by default. The only seemingly positive upside to these exit signs is that they are non-electrical, meaning they won’t rack up anything in electricity bills.

But before you become alarmed with what we have shared with you so far, tritium emits only a low-energy beta radiation, which in turn causes the sealed glass tube it is in to glow (causing the exit sign to give off the illumination it requires). Thankfully, it is rather well known that this type of radiation can hardly (if at all) penetrate a piece of paper or clothing. So while yes it is a very low level (energy wise) type of radiation, the fact that there are alternatives that will remove radiation entirely from your building is all the reason to uninstall your tritium exit signs and replace them with something more safe, like LED exit signs.

Now that you understand the technology and how tritium in exit signs work a little bit more, let’s go over how exactly you can identify whether or not you have these types of exit signs in your building.

Identifying a radioactive exit sign should be fairly easy. All of these signs are required to have some sort of “Caution of Radioactive Material” warning on the fixture.

If you do find such a warning label, it is safe to say your light is made of tritium. Another tell-tale sign is whether or not your signs are connected to an electrical source or not as tritium signs do not require any such connection.

Once you’ve identified if you have a tritium exit sign or not, if you do happen to have one, you may continue on to removing and replacing it with the alternative exit sign, LED.

As with any lighting fixture, we recommend to bring in a professional contractor to do the job. But as a general guideline, you can typically recycle your tritium signs by returning them to the manufacturer or place of purchase.

If you purchased the building with them pre-installed and are unsure of where they came from after inspection of the signs for any brand markings, you can try two things:

1: Try contacting the previous building owner or collect records of where they were manufactured

2: Recycle them with a third party. like these), buying them, then installing them yourself or with a professional (we recommend a professional).

Here are a few things you should remember and keep in mind when dealing with a building that has radioactive exit signs:

In other news, scientists at Syracuse University may have created a new light source that doesn’t need electricity or batteries to produce light. How? The firefly. The scientists found a new way to harness this bioluminescence using nanoscience. Mathew Maye, assistant professor of chemistry at SU explained:

“The nanorods are made of the same materials used in computer chips, solar panels and LED lights. It’s conceivable that someday firefly-coated nanorods could be inserted into LED-type lights that you don’t have to plug in.”

As with any type of home repair service, the cost of a project or repair will vary depending on what type of work you need to have done. If you have an electrical repair, for example, the electrician will need to take out his tools and do some electrical troubleshooting in order to determine exactly what and where the problem is. If this is the case, it’s not possible to give an exact electrical estimate before starting, and the job will need to be done on a time an material basis. The electrician should give you an accurate quote of their hourly rates, and the cost of materials that they charge you for should be realistic. If the electrician is knowledgeable and competent and the repair is straight forward, they can usually fix the issue within a fairly short amount of time and at a reasonable cost.

If you need a panel upgrade, new lighting, smoke detectors or any other type of electrical installation, you’ll want to make sure that you know the exact price before the job is started. For your own protection, this is very important.

Electric Connection, a licensed Pasadena electrician, can give you a ballpark price over the phone for most types of electrical installations, and then schedule an appointment to go out to your house or business property to give you a detailed price in writing. Getting a price in writing for the work you need done means no surprises for you at the end of the job and less stress for you while the job is in progress, too.

If you need an electrical update or installation, you can call our office and let us know exactly what you’re looking for, and we’ll be able to give a ballpark figure and some free electrical advice. If you like the ballpark price, we can schedule an appointment to go out to your property and give you an exact electrical estimate in writing. We’re a licensed and bonded electrician Pasadena area residents can depend on. You can also visit our website at www.theelectricconnection.com/electrician-pasadena-ca to find out more.

Tube lights are found in many applications and environments such as office buildings, hallways, garages, and really anywhere that has a low and flat ceiling. Although fluorescent tubes contain small amounts of mercury and isn’t a whole lot, you still want to avoid the breaking of a fluorescent tube and any exposure to mercury if possible.

Whether you are simply replacing a burnt out fluorescent tube with a new one or are switching over to a new technology (such as LED), there is a proper way to do it. By following these steps along with others that you may find, you will allow yourself to reduce risk of harm for yourself, staff, or whoever is the one physically replacing the tube lights.

Let’s answer some common questions and issues that people seem to face when tasked with this issue of replacing mercury filled fluorescent tubes…

By recycling rather than simply throwing away your tube lights, you opt-in for the environmentally friendly route of switching out old tubes. If you choose not to recycle, you are allowing toxic mercury to freely enter the environment, which of course is not good.

Not only do you prevent mercury from freely entering the environment by recycling, but you also reduce waste. How exactly? Part of the tube is reused for new tubes that will be resold and used. This allows for less waste and this goes back to the saying “Reduce, Reused, Recycle.” So by taking part of fluorescent tube recycling, you allow the process of recycling to continue and prevent waste from entering the landfill!

When taking your tubes out to bring for recycling, this is probably the most difficult step you need to be most cautious with. The best option you have is to be prepared and know what to do if things go “south” as they like to say.

Here is what you can do to prepare for the removal of fluorescent fixtures:

And for one thing that you should always remember for dealing with a broken tube is this: NEVER VACUUM. By vacuuming, you make glass particles go airborne and that is a highly dangerous situation to be in.

For more tips on how to clean up a broken fluorescent or CFL lights, using this tool from Earth911. It allows you to search what you need to recycle and where you are located. So you go to that tool, type in ‘fluorescent’ or ‘CFL’ along with your location and you will surely come across the closest place to recycle fluorescent tubes (along with really anything else you may want to recycle).

If you are in the process of disposing and recycling your fluorescent tubes, what is going in there to replace the ones you are removing? If the answer is “more fluorescent tubes,” may we ask why?
