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:

Limit switches, as the name suggests, are precision switches that are designed to work as limiting devices. The switch is typically snap-action and designed to sense the presence, absence, or be triggered by an excess or lack of physical contact at the position where it is installed.

The flexibility and adaptability of limit switches to different tasks and environments has made them very popular as components of conveyor belt systems.

Industrial conveyor belts are considered to be amongst the greatest inventions for boosting production, as well as reducing time, costs and manpower requirements. They are commonly used in production, mining, assembly lines and just about every major industry or sector today.

They typically consist of a number of pulleys that rotate under a continuous belt. Some of these pulleys are powered and they drive the belt, keeping any material on top continuously moving towards its destination.

Conveyor belts can be broadly classified into two classes, which are:

These conveyors are used for transporting smaller volumes of material like packaged goods, or lighter materials like boxes.

These are heavy duty conveyor systems which are designed to carry heavier loads or bulky materials, like industrial and agricultural goods.

While conveyor belts can tremendously increase efficiency, they are prone to jamming from over-loading unless the correct safety measures are put in place. Limit switches help prevent this by measuring the height or number of individual products passing through the conveyor system. In case the switch senses an object that may cause an obstruction, it shuts the system down to prevent damage or spillage.

Depending on the environment and purpose, there are a variety of limit switches which can be used in conveyor systems:
