How to Build Your Own First Aid Kit (And Why Buying One Might Be Smarter)

Step 1: Why Build Your Own First Aid Kit?

Having a well-stocked first aid kit is essential for handling minor injuries and medical emergencies. While pre-made kits are available, some people choose to build a first aid kit themselves to customize it for their needs. Whether you’re assembling a kit for a hiking trip, workplace, or home use, this guide will walk you through everything you need to create a fully stocked and effective first aid kit.

By the end, you’ll also see why eFirstAidSupplies’ pre-made kits offer a faster, more cost-effective solution without the hassle of sourcing individual supplies.


Step 2: Choosing the Right First Aid Kit Case

Before stocking your kit, you’ll need a container that keeps supplies organized and protected.

Type of CaseBest ForProsCons
Soft-Sided BagTravel, hiking tripsLightweight, flexible, easy to packLess protection from moisture & impact
Hard Plastic CaseHome, workplace, vehicleDurable, waterproof, protects suppliesBulkier, less portable
Metal CaseIndustrial settings, wall-mounted useExtremely durable, protects from damageHeavier than plastic options

💡 Tip: ANSI requires that workplace first aid kits be “weather-resistant and clearly labeled.”


Step 3: Essential Supplies for a First Aid Kit

To build a complete first aid kit, you’ll need to cover wound care, medications, tools, and emergency supplies.

CategoryEssential ItemsPurpose
Wound CareBandages, gauze pads, antiseptic wipes, medical tapeTreat cuts, scrapes, and minor wounds
Injury & TraumaCold packs, roller bandages, splintsReduce swelling and support fractures
Medical ToolsTweezers, scissors, gloves, digital thermometerAid in wound care and emergency response
MedicationsPain relief, antihistamines, burn creamTreat minor pain, allergic reactions, burns
Emergency GearCPR mask, emergency blanketAssist in life-saving situations

💡 Tip: Consider your specific needs—a workplace kit requires OSHA compliance, while a sports kit might need medical sports tape.

Step 4: Sourcing First Aid Supplies

Once you’ve planned your kit, it’s time to gather supplies. Here’s where building a kit yourself can become time-consuming and costly:

  • Buying individually means higher prices—bulk discounts are only available for businesses.
  • Tracking expiration dates on medications and antiseptics requires constant maintenance.
  • Verifying ANSI/OSHA compliance for workplaces adds extra research and effort.

For example, a 24-person plastic first aid kit must meet strict standards, which can be difficult to achieve when assembling a kit from scratch.
