4. Emergency and First-Aid Improviser

Ziplock bags are waterproof, sealable, and transparent, making them invaluable in first-aid and emergency situations, both at home and in the wilderness.
1. Instant Ice Pack
Fill a quart or gallon bag with 2 parts water and 1 part rubbing alcohol. Seal it tightly (double-bagging is recommended for safety) and freeze it. The alcohol prevents the water from freezing solid, creating a soft, malleable, and very cold ice pack that conforms to injuries.
2. Waterproof Protection for Phones and Matches
This is a classic outdoor hack. Before a hike or beach day, seal your phone in a ziplock bag. You can still use the touchscreen through the plastic, and it's protected from water, sand, and dust. Keep matches or tinder in a separate small bag to ensure you have dry fire-starting materials in an emergency.
3. Sterile Environment for First-Aid
In a pinch, a clean ziplock bag can be used to create a barrier for wounds before applying a bandage, or to protect a bandaged wound while showering. They can also be used to safely isolate and dispose of used first-aid materials like gauze or gloves.
