Neon signs have been a popular choice for businesses and advertisers for decades, thanks to their vibrant colours and eye-catching displays. However, some people have raised concerns about the potential dangers of neon signs, including the risk of fires and electrical shocks, as well as the potential health hazards of exposure to the gases used in these signs. In this article, we will explore the potential hazards of neon signs and the safety measures that are in place to protect users and minimise the risks of these hazards.
This is chapter 11 in the neon sign library

How do neon signs work?
First, let’s take a look at how neon signs work. Neon signs are made up of glass tubes that are filled with neon or argon gas. When an electric current is applied to a gas, it can cause the atoms in the gas to become excited and release energy in the form of light. This is known as electrical discharge, and it is the principle behind the neon glow of neon signs.
The color of the light produced by neon signs depends on the type of gas used. Neon gas produces a reddish-orange color, while argon gas produces a pale blue color. By mixing different gases and using different colors of glass tubing, neon sign makers can create a wide range of colors and effects.
How neon lights works
In addition to the gases and electricity, the glass tubing used in neon signs must be carefully bent and shaped into the desired shapes and letters, using specialized tools and techniques. This requires a high degree of skill and precision, and it is one of the reasons why neon signs can be expensive to produce.
Are neon signs dangerous by leaking toxic gasses and chemistry?

Another potential hazard of neon signs is the risk of exposure to the gases used in their production. Neon and argon are inert gases that are generally considered safe. However, in high concentrations, they can pose a risk to human health. Exposure to high levels of these gases can cause asphyxiation and other respiratory problems. Fortunately, this risk is typically minimal, as neon signs are designed to prevent the release of large amounts of gas.
Neon and argon gas are sealed inside the glass tubing of neon signs, and they are only released in small amounts when the electrical current is applied. This means that the risk of exposure to high levels of these gases is typically low, as long as the signs are used and maintained properly.
In addition to the design of neon signs, there are also safety regulations and standards in place to prevent the risks of exposure to these gases. Industry standards and government regulations provide guidelines for the production, installation, and maintenance of neon signs to ensure the safety of users and the public.
Can neon signs cause electric shock?

Neon signs use electricity to operate, but they are designed in a way that prevents electric shock. For example, the glass tubes of neon signs are made of non-conductive materials and are sealed, so there is no way for anyone to come into contact with the electric current. Additionally, neon signs typically have a transformer that reduces the voltage of the electricity to a safe level.
Just like traditional neon signs, LED neon signs do not pose a risk of electric shock. The LED lights used in these signs are low voltage and are sealed in a non-conductive material, so there is no way for anyone to come into contact with the electric current.
This means that neon signs are safe to use and do not pose a risk of electric shock. So, if you’re thinking about adding a neon sign to your home or business, you can confidently do so. Not only will it add a touch of character and charm, but you can rest assured that it is safe to use.
Can neon signs cause the risk of broken glass and falling signs?
However, in addition to the potential electrical and health hazards of neon signs, there are also other potential risks associated with these displays. In this article, we will explore the potential risks of injury from broken glass and damage to property from fallen neon signs and discuss the measures that can be taken to minimize these risks.

One potential risk associated with neon signs is the risk of injury from broken glass. Neon signs are made up of glass tubes that are bent and shaped into the desired shapes and letters. While the glass used in neon signs is specially designed to be strong and durable, it is still possible for the tubes to break if they are mishandled or subjected to excessive force. If a neon sign breaks, it can release shards of sharp glass that can cause cuts and other injuries.
To minimize the risk of injury from broken glass, it is important to follow the manufacturer’s instructions for handling and installing neon signs. This includes using the correct tools and techniques for bending and shaping the glass tubes, as well as ensuring that the signs are securely mounted and supported. In addition, it is important to avoid tampering with neon signs or using them in ways that could cause them to break, such as hanging heavy objects from them or using them in high-wind areas.
Another potential risk associated with neon signs is the risk of damage to property from fallen signs. If a neon sign is not securely mounted or supported, it can fall from its mounting, potentially causing damage to nearby property or structures. In addition, if a neon sign falls from a height, it can cause damage to anything that it falls on.
Is it possible for neon signs to ignite and cause a fire?

Neon signs can ignite and cause a fire, but it is not common. Neon signs use electrified neon gas to create the bright, glowing colors that make them so eye-catching. This gas is contained within a glass tube, sealed at both ends to prevent the gas from escaping. For a neon sign to ignite, the gas inside the tube must escape and come into contact with an ignition source, such as a spark or open flame.
Several factors can cause the gas in a neon sign to escape and potentially ignite. One of the most common is damage to the glass tube. If the tube is cracked or broken, the gas inside can leak out and come into contact with other materials, potentially igniting a fire. Another potential cause of gas leakage is improper installation or maintenance of the neon sign. If the sign is not secured correctly or the connections between the tube and the power source are not tight, gas can escape and potentially ignite.
To prevent a neon sign from igniting and causing a fire, it is essential to inspect the sign for damage regularly and to maintain and install it properly. If the sign is damaged or not working correctly, it should be repaired or replaced as soon as possible. In addition, it is essential to keep the area around the neon sign free of flammable materials and to avoid exposing the sign to extreme temperatures or other potentially hazardous conditions. Following these guidelines can significantly reduce the risk of a neon sign igniting and causing a fire.
Are neon signs safe for the environment?
Neon signs are generally safe for the environment when properly disposed of. Neon signs use electrified neon gas to create their bright, glowing colors. This gas is contained within a glass tube, sealed at both ends to prevent the gas from escaping. Therefore, when the neon sign is functioning correctly, the gas is not released into the environment and poses no threat.
However, there are some potential environmental concerns associated with neon signs. One of the biggest concerns is the disposal of neon signs that are no longer in use. If a neon sign is not properly disposed of, the gas inside the tube can leak out and potentially harm the environment. This is especially true if the sign is broken or damaged, as the gas can escape more easily. To avoid this, it is essential to dispose of neon signs properly and to recycle the glass and other materials whenever possible.
Another potential environmental concern is the manufacturing of neon signs. Creating glass tubes and filling them with neon gas can produce some waste materials and emissions. However, many neon sign manufacturers have implemented eco-friendly practices and use recycled materials to reduce their environmental impact. By choosing to buy neon signs from manufacturers with a commitment to sustainability, the environmental impact of neon signs can be minimized.
