Are Neon Signs Flammable?

One concern that many people have about neon signs is their flammability. While it is true that neon signs are made using gas and electricity, they are not necessarily more flammable than other types of signs. In addition, neon signs are often considered safer than other signs because they do not generate heat.


However, it is essential to note that neon signs can still pose a fire risk if they are not installed or maintained correctly. For example, if the wiring is damaged or the sign is not properly grounded, it could spark and start a fire. Additionally, if the sign is located near flammable materials, such as curtains or paper products, it could increase the fire risk.


To minimize the risk of fire or injury, it is essential to have neon signs installed and maintained by a professional. They can ensure that the sign is grounded correctly, the wiring is in good condition, and the sign is located in a safe area.


Neon Signs In San Francisco

Neon signs have been a fixture of urban landscapes for over a century, and San Francisco is no exception. From the iconic “Haight-Ashbury” sign to the colorful displays in Chinatown, neon signs are ubiquitous in the city. However, as with any electrical device, there are concerns about its safety.


What Are Neon Signs Made Of?

Neon signs are made of glass tubes filled with a gas, usually neon, which emits a colorful glow when an electrical current is passed through it. The tubes are bent into various shapes and connected to electrodes supplying the current. The gas inside the tubes is under low pressure, which helps to prevent them from breaking.


How Do Neon Signs Work?

When an electrical current is passed through the gas in the tubes, it causes the gas to ionize or become charged. This ionization process releases energy in the form of light, which creates the sign’s bright, colorful glow.


Regulations For Neon Signs In San Francisco

Local and state codes regulate the use of neon signs, which mandate specific installation and maintenance requirements to ensure their safety. In San Francisco, businesses that use neon signs must obtain a permit from the Department of Building Inspection, which requires a review of the sign’s design and installation plans. Additionally, the sign must be inspected by a licensed electrician to ensure that it meets all safety requirements.


How To Safely Use Neon Signs?

It is important to follow safe installation and maintenance practices when using neon signs to minimize the risk of fire or injury. These practices include:


  • Hiring a licensed electrician to install and maintain the sign.
  • Ensuring that the sign is properly grounded.
  • Keeping the sign away from combustible materials.
  • Regularly inspecting the sign for damage or wear.
  • Keeping the sign away from areas where it may be knocked over or bumped.
  • Alternatives to neon signs.


While neon signs are popular for businesses and homeowners, alternatives offer similar aesthetic appeal without the same safety concerns. LED signs, for example, can create a similar look to neon signs while consuming less energy and posing less of a fire hazard.

For one, they offer a unique and eye-catching aesthetic to help businesses stand out and attract customers.

Neon Signs And The Environment

While neon signs are not typically considered environmentally friendly, there are ways to reduce their impact. For example, businesses can choose to use energy-efficient neon tubes or switch to LED signs, which use less energy and are more environmentally friendly. Additionally, companies can recycle or repurpose their neon signs when they are no longer used.
