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:

Pool lighting makes up a major part of your overall swimming pool costs, so it’s important that you figure out which type works best before you install them. The two major types of pool lighting are in ground lighting and above ground lighting, and your budget, needs, and preferences all factor largely into deciding which type to install. We’ll help you break down all types of pool lights to help you make the best choice for your Maryland, Virginia, or Washington, DC home—just keep reading!

One of the biggest benefits of in ground pool lighting is its streamlined look and even lighting. The two primary options for in ground pool lighting are LED lighting and fiber optic lighting (we’ll get into the pros and cons of each further down in this blog post).

Usually much cheaper than in ground pool lighting, above ground pool lighting is perfect for DC area homeowners looking to install a pool on a budget. There are a number of different ways to install above ground pool lighting, including:

Floating Pool Lighting

Floating pool lighting is exactly what it looks like. This type of pool lighting involves lights that bob up and down on the surface of your pool. It is available in a variety of colors and shapes, from orbs, cubes, and pods to more creative features like jellyfish shapes, flowers, and more. Floating lights can be solar powered and tend to use bright LEDs, but since they move around they don’t provide perfectly even lighting.

Magnetic Pool Lighting

If you have a soft-sided pool, magnetic pool lights are perfect for you. These two-part lights can be attached to the liner of your pool for an in ground pool lighting appearance with above ground ease.

The two major types of in ground pool lighting are LED and fiber optic, and each type has its own advantages and disadvantages for homeowners in Maryland, Virginia, and Washington, DC. Consider the following:

LED lighting – LED lights are housed in waterproof bulbs that can be removed to change the bulb. The bulb itself should last around 10,000 hours, however, so you won’t need to perform even this simple task very often. One to two bulbs should be enough to illuminate your entire swimming pool.

Fiber optic lighting – bulbs for fiber optic pool lights are located out of the water, making them even easier to access and replace than LED pool lights. To illuminate a whole pool, you’ll likely need more than one fiber optic light, though, which can get expensive.

LED lighting – LED lights range from $400 – $900 installed, and bulbs can last anywhere from 10 – 15 years. Replacement bulbs will run you about $200 – $400.

Fiber optic lighting – a fiber optic pool lighting system will require a fan to keep the light cool, meaning fiber optic pool lighting will be more expensive than LED lighting—think anywhere from $900 – $1,500 per bulb system. Bulbs typically last about 3 – 7 years, and replacing them will cost about $200 – $300.

LED lights – despite having the lighting components under water, LED lights are very safe and have a very low risk of failure. In addition, LED lights use very low voltage, which mitigates the risk further.

Fiber optic lighting – since there are no electrical components housed in the water, fiber optic lighting has close to zero risk of electric shock.

LED lights – LED lights can be used to fill your whole pool with light and illuminate the whole thing at once. They can also change colors to create a truly unique look for your backyard.

Fiber optic lighting – these types of pool lights aren’t as good at illuminating the whole pool at once, but they can create points of light to give your pool a sparkling, starry appearance.

In purely practical terms, LED lights have the edge over fiber optic lights—they are less expensive, easier to maintain, and provide much brighter illumination. But there are advantages to both types of pool lights, and Kolb Electric can help you find the perfect fit for you and your home. We can also provide you with further pool lighting tips here.

Being a home owner comes with more responsibility than some people realize, and it can get overwhelming. There are certain aspects about your home that you may have overlooked, or just thought wasn’t important, like your HVAC system. Not paying attention to your HVAC can become very troublesome for your home and cause several issues.
