Keeping hand sanitizer in your car might seem convenient, especially during these times when frequent hand hygiene is crucial. However, it’s important to be aware of the risks associated with leaving sanitizer in a hot vehicle, particularly during the summer months.
Why It’s Risky:
- Flammability: Hand sanitizers, especially those containing alcohol (usually 60-70% ethanol or isopropanol), are highly flammable. If left in a hot car, the temperature inside can rise significantly, potentially leading to the ignition of the sanitizer. While it requires a very high temperature to catch fire, the risk is still present under extreme conditions.
- Effectiveness: High temperatures can cause the alcohol in the sanitizer to evaporate, reducing its effectiveness. This means that the sanitizer might not be as potent in killing germs when you need it.
- Container Integrity: The heat can also cause the bottle or container to warp, crack, or burst, leading to leaks. This can create a mess in your car and increase the risk of flammable vapors accumulating in the confined space.
Safety Tips:
- Store Sanitizer in a Cool Place: If you need to keep sanitizer in your car, store it in a cooler or a shaded area to minimize heat exposure.
- Use Smaller Bottles: Keep a small, travel-sized bottle of sanitizer with you instead of a large container that might be more prone to overheating.
- Monitor Car Temperature: Be mindful of how hot your car gets, especially if it’s parked in direct sunlight.
In summary, while hand sanitizer is essential, it’s best to avoid leaving it in your car for extended periods, particularly during hot weather. Taking these precautions can help you stay safe and ensure your sanitizer remains effective when you need it most.
