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:

To Tampa residents, power outages are nothing new. We’ve dealt with all kinds of crazy storms and annoying weather in our time here, and it can be quite flustering if you’re not sure how to handle things. But if you’re prepared and know what to do, an outage can become little more than brief annoyance. Find out what to do during an outage with the help of the experts at Hoffman Electrical!

We all know or at least heard that converting from Metal Halide (High Intensity Discharge) to LED will save you money.

But how much? Are there any other reasons or difference you should know about?

In this article, we break down all the factors that you should be aware of before making a decision to convert from Metal Halide to LED. Here are the 9 reasons we think LED wins over Metal Halide.

Let’s take a look at the information on a typical 400 watt metal halide bulb. While specifications may vary, a visit to a popular online website that sells Metal Halide bulbs shows that a brand new bulb has the following specifications:

We have just as many customers wanting to convert to LED because of maintenance savings as they do for energy savings. Think about what we discussed, over the life of the LED retrofit kit, a customer would have to do 5-6 Metal Halide replacements. The higher the installation height, the higher the cost of replacement. And if you have a facility loaded with lights, this becomes a significant budget amount every year that you must take into consideration. Now, we know that reduced maintenance time on lights does not translate into dollars saved because it is highly unlikely that people will lose their jobs over the fact there is much less work to do. However, these people will have time to now work on things that matter, like fixing the machines that make the company money instead on replacing lights that cost the company money.

When you take a measurement of light with a light meter, it reads lumens. And this measurement of all the lights that contribute to the light at that location creates a measurement called foot candles. But let’s think about that light that is being measured. Metal Halide creates all sorts of light, in all spectrum’s, visible or otherwise. This includes UV and IR spectrum’s, visible to the measuring device but not visible to the human eye. LED, on the other hand, does not produce UV and IR. Therefore, its readings using the same light meter is only picking up visible spectrum’s.

So there is a fun little test you can do. Have 2 light sources, LED and Metal Halide. And first ask, which one is brighter? And if the right LED source was selected, they should say LED. And then use a light meter, and the light meter may say the Metal Halide area is producing more foot candles. And so now you know part of the reason, but wait, there’s 2 other pieces of information you need to know.
