How to Use a Medical Emergency Information Tag

Staying prepared shouldn’t be complicated. A Medical Emergency Information (MEI) tag is a no-tech, no-fail tool that stores your critical health details and emergency contacts directly on your personal gear. It’s designed to help first responders and loved ones act quickly—even when you can’t speak for yourself.

Whether you’re a parent, cyclist, athlete, outdoor enthusiast, or at work, setting up your MEI takes only a few minutes

What is a MEI tag used for?

An MEI tag contains the important personal information you want others to know in the event of an emergency. Information such as allergies, medical conditions, medications, blood type and emergency contacts. It attaches securely to items like helmets, hard hats, backpacks, mobility aids, car seats, jackets, and more. During an emergency—like an injury, sudden illness, or allergic reaction—this information helps responders help you.

To learn more about emergency preparedness tools, here are essential tips to be better prepared and to recover from emergencies.

How to Use a MEI Tag: 3 Easy Steps

The MEI setup includes three simple steps:

Step 1: Complete your information card

Use a pencil so you can update your details later.

Write down:

  • Name
  • Emergency contact information
  • Medications
  • Allergies
  • Medical conditions
  • If you have a pet at home that needs to be attended to
  • Any other important information

Make sure both sides of the card are filled in. Clear writing ensures emergency medical responders can act accurately under pressure.

Step 2: Insert the card into the MEI carrier

Fold the completed card carefully and slide it into the MEI carrier. Tuck in the flap to keep the information protected from water and dirt. This keeps your health records safe from water, sweat, and weather.

Step 3: Attach the MEI to your gear

You can attach the MEI in two ways:

Option A: Adhesive attachment (most common)


Ideal for helmets, backpacks, PPE, and other safety equipment.

  1. Peel the adhesive on one side of the carrier.
  2. Press it firmly onto your helmet, backpack, hard hat, or other gear.
  3. Trim any extra adhesive.
  4. Peel the second adhesive backing and press it tightly to seal.


Option B: Zip-tie attachment (high-impact activities)


Remove the adhesive tab and secure the carrier to gear using a zip tie. This is helpful for items exposed to weather, vibration, or movement. Best for high-impact activities, construction gear, or outdoor equipment.

Works best on:

  • Protective helmets
  • Cycling helmets
  • Ski helmets
  • Hockey helmets
  • Backpacks and hydration packs
  • Mobility aids
  • Car seats
  • Motorcycle helmets
  • PPE and work vests

Who Should Use an MEI Tag?

  • Workers in hard-hat industries  
  • Warehouse and manufacturing staff 
  • Cyclists and outdoor enthusiasts
  • Parents of school-age children wanting quick access to emergency contacts

Why an MEI Tag is Important in Emergencies

First responders often need to make quick decisions, including checking for allergies, medications, or medical conditions that could affect treatment. Having this information stored on your MEI medical ID helps them act safely and confidently.
 

The MEI is:

  • Durable and waterproof
  • Highly visible to first responders
  • Lightweight and secure
  • Usable on a wide range of personal gear
  • Developed in partnership with Canadian Red Cross first aid programs

It's a simple tool that can reduce confusion, save time, and support better care in an emergency. In emergencies—especially when every second counts— having clear medical information available can save valuable time and prevent medical errors.

Frequently Asked Questions About Using an MEI Tag

Is the MEI tag helpful in medical emergencies?
Yes. It helps responders quickly verify personal information, blood type, medical conditions, and emergency contacts.

Can I update my MEI information later?
Yes. Because it’s filled out in pencil, you can update your card anytime.

Is the MEI tag waterproof?
The carrier is water-resistant and designed to protect your information in outdoor and workplace conditions. The paper insert is made from waterproof paper.

Where should I place the MEI tag for best visibility?
The best location is a flat, visible surface—like a helmet, hard hat, backpack front, or mobility aid.

Can children use the MEI medical ID?
Yes. Children usually don’t have identification with them, and in emergencies, they might be too frightened, too young, or unable to share their medical needs. Attaching an MEI to a backpack, lunch kit, or jacket makes ensures school staff and first responders can reach parents quickly.

Can people use the MEI tag in workplace settings?
Yes. It's widely used for workplace safety, especially where helmets or PPE are required.
