Frequently Asked Questions

Find answers to the most common questions about emergency first aid and medical supplies, from tourniquets, hemostatic dressings, and chest seals to expiration dates, glove materials, and training. In an emergency, the right supply used the right way can save a life.

Should I get a first aid kit or individual medical supplies?

A first aid kit gives you a pre-assembled foundation for treating common injuries. Individual medical supplies let you restock used items, expand a kit for your specific risks, or build a dedicated trauma station for a school, office, or job site. Many customers start with one of our First Aid & Trauma Kits and add items like tourniquets, chest seals, and extra gloves from this category.

When should a tourniquet be used?

Use a tourniquet for severe, life-threatening bleeding from an arm or leg that cannot be controlled with direct pressure. Apply it high above the wound, tighten until the bleeding stops, note the time of application, and get emergency medical care immediately. The CAT Gen 7 Combat Application Tourniquet is designed for fast one-handed application.

How does a QuikClot hemostatic dressing work?

QuikClot dressings are impregnated with kaolin, a mineral that accelerates your body's natural clotting process. Pack the dressing into or onto the wound and apply firm, continuous pressure. Hemostatic dressings are used for serious bleeding in areas where a tourniquet cannot be applied, such as the torso, neck, or groin.

What is a chest seal and when is it used?

A chest seal is an occlusive dressing applied over a penetrating chest wound, such as a gunshot or stab wound, to keep air from entering the chest cavity. Vented designs like the HyFin Vent Chest Seal allow trapped air to escape, which helps reduce the risk of tension pneumothorax while awaiting emergency responders.

Do first aid and medical supplies expire?

Yes. Sterile items such as dressings, gauze, and chest seals carry expiration dates, and materials like gloves and adhesives degrade over time. Check your supplies at least once a year, replace anything expired or damaged, and keep items stored in a cool, dry location to maximize shelf life.

Do I need special training to use trauma supplies like tourniquets and chest seals?

Basic supplies like bandages, gloves, and splints require no formal training. Trauma items such as tourniquets, hemostatic dressings, and chest seals are most effective when you have hands-on training. A Stop the Bleed course or a first aid/CPR class is a worthwhile investment for anyone who keeps trauma supplies on hand.
