What Makes Hand Sanitizer Flammable and Why It Matters

During the ongoing coronavirus pandemic, hand sanitizers have become a household staple for personal hygiene and public safety. However, these seemingly innocuous products can pose significant fire hazards due to their flammable nature. This article will explore the key factors that make hand sanitizer flammable and precautions to take to ensure a safe environment.

Understanding the Flammability of Hand Sanitizer

Hand sanitizer is primarily composed of various types of alcohol, the most common being ethyl alcohol and isopropyl alcohol. The alcohol concentration in hand sanitizers typically ranges from 60 to 95 percent. This high alcohol content significantly contributes to the flammability of these products.

Alcohol Concentration

The higher the alcohol concentration in a hand sanitizer, the more flammable the product becomes. This is because alcohol has a low flash point, meaning it can ignite at relatively low temperatures. A flash point is the lowest temperature at which a substance can form an ignitable mixture with air near the surface of the liquid.

Volatility

A significant factor in the flammability of hand sanitizer is its volatility. Alcohol is a volatile substance, meaning it evaporates easily at room temperature. When it evaporates, it forms flammable vapors that can ignite when exposed to an open flame or spark. It's crucial to understand that proper handling and proper storage are essential to mitigate these risks.

Ignition Sources

Common ignition sources such as matches, lighters, or even static electricity can easily ignite the vapors produced by hand sanitizer. Flammable materials like paper, cardboard, or clothing can be ignited by these vapors, leading to potential fires. Care must be taken to avoid these sources when using hand sanitizer, especially in areas where open flames or sparks may be present.

Container Material

The packaging of hand sanitizer also plays a role in flammability. Many hand sanitizers are stored in plastic or other materials that can melt or ignite when exposed to high heat or flames. This increases the risk of fire hazards and emphasises the importance of storing hand sanitizer in a cool, dry place away from heat sources and open flames.

Risk Management and Prevention

To prevent fire hazards, it's essential to take several precautions when using hand sanitizer:

Proper Application: Always apply hand sanitizer until your hands are thoroughly moistened. Allow the product to dry completely before handling electronic devices or other materials that may ignite the flammable vapors. Avoid Wiping Off: Avoid wiping off the hand sanitizer before it has dried. This reduces flammable vapor formation and minimizes the risk of ignition. Storage: Store hand sanitizer in a cool, dry place away from sources of heat, open flames, and other flammable materials. Avoid keeping it in direct sunlight or in areas with high temperatures. Check Expiration Dates: Use hand sanitizer before its expiration date to ensure its effectiveness and minimize the risk of flammability due to decomposition.

Herbal Hand Sanitizers: A Safer Alternative?

While most hand sanitizers are alcohol-based, there are herbal alternatives that contain essential oils. Essential oils are generally flammable, but their concentrations are usually very low. At these low concentrations, essential oils are not flammable. However, it's important to note that they can still pose risks if not used and stored properly.

Non-Alcohol-Based Options

Some non-alcohol-based hand sanitizers are available, but they generally do not have flame warnings and are assumed to be non-flammable. However, it's advisable to check the product labels and follow safety instructions provided by the manufacturer. Product safety professionals and regulatory bodies like the FDA usually ensure that such products are safe and properly labeled.

Conclusion

Hand sanitizers are effective tools for maintaining hygiene during the pandemic, but their flammable nature requires careful handling and storage to prevent fire hazards. By understanding the key factors that contribute to the flammability of hand sanitizer and taking appropriate precautions, we can enjoy the benefits of these products without compromising safety.
