First Aid Kit Guide | What to Pack & Why It Matters

A well-stocked first aid kit contains bandages, antiseptics, medications, and tools to treat minor injuries and manage emergencies until professional help arrives.

A first aid kit is a portable container of basic medical supplies designed to treat minor injuries and manage emergencies until professional help arrives. For a US household, the essential kit must include adhesive bandages in assorted sizes, sterile gauze pads (2-inch and 4-inch), adhesive tape, antiseptic wipes, antibiotic ointment, hydrocortisone cream, over-the-counter pain relievers (acetaminophen/ibuprofen), antihistamines, triangular bandages, safety pins, disposable latex-free gloves, sharp scissors with rounded tips, tweezers, a non-mercury thermometer, and a first aid manual. Getting the right supplies assembled in one place means you’re prepared before something happens — and knowing what each item does is just as important as owning it.

What Belongs in a Household First Aid Kit?

A complete household kit breaks down into four supply categories: wound care, medications, tools, and documentation. Here’s what each should include.

Wound care supplies handle cuts, scrapes, and minor bleeding. Pack adhesive bandages in assorted sizes, butterfly bandages, sterile gauze pads in 2-inch and 4-inch sizes, gauze rolls, elastic wraps, adhesive tape, and antiseptic wipes. These cover the vast majority of minor injuries at home.

OTC medications worth including are acetaminophen, ibuprofen, aspirin (adults only), antihistamines like diphenhydramine, antacid, hydrocortisone cream (1%), calamine lotion, aloe vera gel, and antibiotic ointment.

Essential tools include latex-free disposable gloves, scissors with rounded tips, tweezers, safety pins, a digital thermometer (never mercury-based), a CPR pocket mask, and instant cold packs. These let you handle everything from splinter removal to applying pressure on a bleeding wound.

Documentation keeps you prepared for serious situations: emergency numbers including Poison Control (1-800-222-1222), medical consent forms, and a family medical history list covering allergies and current medications.

How First Aid Kit Needs Change by Setting

The same supplies that work at home may not fit a travel pouch, workplace box, or emergency disaster kit. Here’s how the contents shift by use case.

Kit Type Key Additions Important Rules
Household Full wound care, OTC meds, tools, documentation No mercury thermometers
Travel Antidiarrheal, motion sickness meds, sunscreen, insect repellent, water purification tablets Cold packs and liquids may be restricted in carry-on
Workplace Sterile plasters, eye pads, triangular bandages, wound dressings, foil blankets No medications allowed in workplace first aid boxes
Emergency/Disaster Water, food, radio, flashlight, whistle, dust mask, plastic sheeting, duct tape Rotate water every 6 months; check food expiration dates

Travel kits specifically need antidiarrheal medication (Imodium), motion sickness remedies, sunscreen SPF 15 or higher, insect repellent (applied separately from sunscreen, not combined), and water purification tablets. Cold packs and liquid medications may need to go in checked luggage — verify current airline rules before flying.

Workplace kits follow Red Cross guidance and must stay medication-free: sterile plasters, eye pads, triangular bandages, large and medium wound dressings, disposable gloves, face shields or pocket masks, alcohol-free cleansing wipes, adhesive tape, and foil blankets. Keeping medications in a workplace first aid box is prohibited.

Emergency disaster kits go well beyond basic first aid. FEMA recommends one gallon of water per person per day for three days, a three-day supply of non-perishable food, a battery-powered or hand-crank NOAA Weather Radio, a flashlight, extra batteries, a whistle, dust masks, plastic sheeting, duct tape, and a manual can opener. Add prescription medications, infant formula, pet food, cash, and copies of important documents.

How to Maintain and Store Your Kit

A first aid kit is only useful when its contents are current and accessible. Check expiration dates on medications and packaged supplies at least twice a year — tying this to daylight saving time changes makes it easy to remember. Replace water supplies in disaster kits every six months. Review family needs annually and update medical records, allergy information, and emergency contact numbers.

The CDC’s guidelines recommend storing kits in a cool, dry place — not in a bathroom where humidity degrades supplies faster. Keep separate kits for home, work, and car instead of relying on one central location. When assembling a new kit, use a checklist and mark items off as you pack them, then put an updated copy inside the box so you always know what’s in there. The CDC’s complete first aid kit checklist and assembly guide provides a detailed reference for building a thorough kit.

FAQs

What is the minimum I need in a basic first aid kit?

A basic household kit needs adhesive bandages in multiple sizes, sterile gauze pads, adhesive tape, antiseptic wipes, antibiotic ointment, pain relievers (acetaminophen and ibuprofen), antihistamines, disposable gloves, scissors, tweezers, a digital thermometer, and a first aid manual. These cover common minor injuries at home.

How often should I replace first aid kit supplies?

Check medication and packaged supply expiration dates at least twice a year. Replace water in disaster kits every six months. Review the entire kit’s contents once a year and update any family medical information, including allergies and emergency contacts.

Can I keep aspirin or other meds in a workplace first aid kit?

No — medications including pain relievers, creams, and tablets should not be stored in workplace first aid boxes. Workplace kits should contain only non-medicated supplies like bandages, gloves, wound dressings, and foil blankets. Keep personal medications at your desk or in a locked drawer instead.
