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:

The weather is starting to get cooler, and as summer rolls into fall, we thought we’d remind everyone of ways they can keep their homes safe from fires!

Check your smoke detectors—you should test your smoke detectors twice a year—once in the spring, once in the fall. In addition, remember that smoke detectors are designed to last 10 years. If yours is older than that, it’s highly recommended that you install a new one. New smoke detector laws that went into effect earlier this year require all new smoke detectors to have 10-year batteries, so you don’t have to worry about replacing the batteries along the way.

Check carbon monoxide (CO) detectors—having a smoke detector isn’t enough anymore; if you want to keep your family totally safe, you need to also install a carbon monoxide detector. Carbon monoxide is an odorless, colorless, and highly toxic gas that can be deadly even in small amounts and can be released by any faulty gas appliance, including furnaces and fireplaces. Your best bet? Install a combination smoke alarm/carbon monoxide alarm for maximum protection.

Inspect your extension cords—with the holidays coming up, you’re going to want to make sure your extension cords are in good shape and not damaged or frayed. Any extension cords you’re planning on using outdoors should be weather-rated. Inside, make sure you use surge protectors and power strips with internal overload protection, and make sure you minimize the amount of adapters plugged into a single outlet.

Be careful with space heaters—space heaters are convenient, but can be a major fire hazard if you’re not careful with them. Make sure there is nothing flammable within three feet of the space heater, and never plug it into an extension cord.

Protect your outdoor electrical systems—any outdoor electrical outlets should be GFCI outlets and covered by a “bubble cover” to keep the elements out. If your electrical service cable is exposed, make sure it’s not damaged. During the holidays, don’t hang any decorations on or near the cable.

Install arc fault circuit interrupters—these are not required by building codes, but they offer a higher level of protection for your electrical system and are generally highly recommended. Arc fault circuit interrupters (AFCI) are designed to detect an unintended electrical arc and disconnect the power before an electrical fire can start.  They are the safest way to protect a home from the risk of electrical fire.

If you’re at all concerned with your home’s electrical safety this year, don’t take chances—call Kolb Electric! We can upgrade your home’s electrical service in any way you need, from installing smoke detectors and adding outlets to a full-on heavy up. Don’t gamble on fire safety—call Kolb Electric today!

Now, why is the blue LED so important? Quite simply because there are no white LEDs. The white light that our eyes detect is created by using a blue LED and some yellow phosphor. The yellow phosphor coating may be placed directly on the blue LED or on the glass envelope that houses the blue LED. Either way when the blue light from the blue LED passes through the yellow phosphor the resulting light appears to be white.

In late 2014 at the Nobel Prize Award Ceremony in Stockholm, Sweden, the three Japanese scientists who developed the blue LED while working at Nichia Chemicals will share the Nobel Prize in Physics for their work on the blue LED. In official terms the Nobel Committee awarded this year’s physics prize to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura “for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources.”

Furthermore, the Nobel Committee pointed out in its announcement that the results of all the scientists’ hard work will be on display everywhere as the three recipients make their way through Stockholm: “the light from their invention will be glowing in virtually all the windows of the city.” And they can be assured that, as this century progresses, the ascendancy of the LED will only become more dramatic.

May is National Electrical Safety Month, which is appropriate given the fact that this time of year is when many Virginians began taking out electric lawn equipment, setting up their swimming pools and undergoing major home renovations that necessitate the use of electrical devices. As a result, Virginia residents are more likely to encounter electrical hazards or fall victim to an electrical mishap in the spring than probably any other time of year.

According to data from the U.S. Consumer Product Safety Commission (CPSC), there are roughly 400 electrocutions in the United States annually. Of those 400, almost half are related to consumer products that are mishandled, installed poorly or have faulty wiring. The largest portion of these fatalities involve large household appliances that are used by millions of Americans every day.

While 20 percent of the total mishaps were caused by faulty wiring, another big percentage of electrocutions are actually related to the power lines. Nearly 5 percent of all deaths from these electrocutions were caused when a ladder contacted one of these high-voltage wires during routine home maintenance.

If you are looking to undergo a home renovation that requires use of a ladder, be careful to avoid placing it anywhere near your home's main connection to the power grid. You don't even have to come into direct contact with these lines to become electrocuted, as a good portion of these incidents are caused by electrical arcing between the wire and a ladder. Because of this danger, remain at least 10 feet beneath any power line when you set your ladder up.
