Is Rubbing Alcohol Flammable?

Rubbing alcohol, also known as isopropyl alcohol, is a common household item that many people use for cleaning and disinfecting. However, one question that often arises is whether rubbing alcohol is flammable or not. In this article, we will explore the flammability of rubbing alcohol to help you understand how to handle it safely.

What is Rubbing Alcohol?

Rubbing alcohol is a clear, colorless liquid that is commonly used as a disinfectant or cleaning agent. It can be found in various concentrations, ranging from 70% to 99%, with the most common strength being 70% isopropyl alcohol.

Rubbing alcohol is widely used for its antiseptic properties. It can kill bacteria, viruses, and fungi on the skin and surfaces, making it an excellent choice for cleaning wounds or disinfecting household items.

Is Rubbing Alcohol Flammable?

Yes, rubbing alcohol is highly flammable. The flammability of rubbing alcohol is due to its chemical structure and low flashpoint. Flashpoint is the minimum temperature at which a liquid gives off enough vapors to form an ignitable mixture with the air.

Rubbing alcohol has a flashpoint of around 53 degrees Fahrenheit or 12 degrees Celsius. This means that at or above this temperature, rubbing alcohol can easily vaporize into the air and create flammable vapors.

How Does Rubbing Alcohol Catch Fire?

To catch fire, three elements are required: fuel, heat, and oxygen. Rubbing alcohol, being a flammable liquid, serves as the fuel in this case. It evaporates quickly and releases flammable vapors into the air.

When exposed to a source of ignition, such as an open flame, spark, or even a hot surface, the vapors from rubbing alcohol can ignite and cause a fire. These fires can spread rapidly, especially if the rubbing alcohol is in a container or spilled onto a surface.

It’s important to note that rubbing alcohol fires can be invisible, as the flame may be nearly colorless. This makes them even more dangerous, as they can go unnoticed until they have already caused significant damage.

Safety Precautions

Given the flammability of rubbing alcohol, it’s crucial to handle it with care and follow these safety precautions:

  • Store rubbing alcohol in a cool, well-ventilated area away from any heat sources or open flames.
  • Keep rubbing alcohol away from sparks, static electricity, and hot surfaces.
  • Do not smoke or use any open flames near rubbing alcohol.
  • If a fire occurs, do not attempt to extinguish it with water. Use an appropriate fire extinguisher or smother the flames with a non-flammable material.
  • Always read and follow the instructions on the bottle of rubbing alcohol.

By following these safety precautions, you can minimize the risk of accidents and potential fires caused by rubbing alcohol.

Frequently Asked Questions On Is Rubbing Alcohol Flammable

Is Rubbing Alcohol Flammable?

Yes, rubbing alcohol is highly flammable due to its low flash point and high evaporation rate. It should be handled with caution and kept away from open flames and heat sources.

Can You Start A Fire With Rubbing Alcohol?

Yes, rubbing alcohol can easily start a fire. Its flammable nature makes it a potential ignition source, especially when exposed to heat, sparks, or an open flame.

What Happens If You Light Rubbing Alcohol?

If you light rubbing alcohol, it will ignite and produce a blue flame. The heat generated can be dangerous and cause burns. It’s crucial to exercise caution and avoid potential fire hazards.

How Should I Store Rubbing Alcohol?

Rubbing alcohol should be stored in a cool, well-ventilated area away from direct sunlight and heat sources. It is advisable to keep it in a tightly sealed container and away from open flames or ignition sources.


Yes, rubbing alcohol is flammable. Its low flashpoint and ability to release flammable vapors make it a potential fire hazard if not handled properly. It’s important to keep this in mind and take necessary precautions when using and storing rubbing alcohol to ensure safety in your home.
