Is Isopropyl Alcohol Flammable? Discover the Surprising Truth!

Is Isopropyl Alcohol Flammable?

Isopropyl alcohol, also known as isopropanol or IPA, is a common household chemical that is widely used as a solvent and cleaning agent. It is also used in the manufacturing of a variety of products, including cosmetics, personal care items, and pharmaceuticals. One question that often comes up when using isopropyl alcohol is whether it is flammable or not. In this article, we will explore the flammability of isopropyl alcohol and discuss some important safety precautions that should be taken when handling and storing it.

Flammability of Isopropyl Alcohol

Isopropyl alcohol is indeed flammable. It is classified as a Class 3 flammable liquid, according to the National Fire Protection Association (NFPA) hazard classification system. This means that it can ignite easily when exposed to an open flame, sparks, or heat sources. Isopropyl alcohol has a relatively low flash point, which is the temperature at which it can produce enough vapor to ignite in the presence of an ignition source. The flash point of isopropyl alcohol is about 53 degrees Fahrenheit or 11.7 degrees Celsius.

It is important to note that the flammability of isopropyl alcohol increases with its concentration. The higher the concentration of isopropyl alcohol, the more flammable it becomes. For example, a solution containing 70% isopropyl alcohol is more flammable than a solution containing only 30% isopropyl alcohol.

Safety Precautions

Due to its flammability, it is crucial to handle and store isopropyl alcohol with care. Here are some important safety precautions to follow when working with isopropyl alcohol:

  1. Avoid Open Flames: Keep isopropyl alcohol away from open flames, sparks, and heat sources. This includes cigarettes, candles, and electrical appliances that generate heat. It is important to use isopropyl alcohol in a well-ventilated area to minimize the risk of fire.
  2. Proper Storage: Store isopropyl alcohol in a cool, dry place in a tightly closed container. Make sure to keep it away from direct sunlight and sources of heat. Also, avoid storing it near flammable materials or substances, such as gasoline or paint thinners.
  3. Use in a Well-Ventilated Area: When using isopropyl alcohol, make sure to do so in a well-ventilated area. Open windows or use fans to circulate the air and prevent the buildup of flammable vapors. This is especially important when using large quantities of isopropyl alcohol or when using it in an enclosed space.
  4. Avoid Skin Contact: Isopropyl alcohol can cause skin irritation and dryness. It is advisable to wear gloves and protective clothing when handling it. If it comes into contact with the skin, wash the area thoroughly with soap and water.
  5. Keep Away from Children: Isopropyl alcohol should be stored out of reach of children. It is a toxic substance and can be harmful if ingested. Always keep it in a locked cabinet or high shelf.
