How to properly put on and take off a medical mask?

Medical masks are an important protective tool for preventing respiratory infectious diseases. Wearing and removing masks correctly can effectively reduce the risk of infection. Below are detailed steps and precautions:

I. The Correct Way to Wear a Medical Mask

1. Check the integrity of the mask.

Make sure the mask is free of tears, stains, or moisture.

Confirm the front and back sides as well as the top and bottom directions of the mask (usually, the darker side faces outward, while the lighter side or the side with the metal strip faces upward).

2. Clean your hands

Before wearing, wash your hands with soap and running water, or disinfect them with an alcohol-based hand sanitizer to prevent bacterial contamination of the mask.

3. Wearing steps

Unfold the mask: Hold the mask’s ear loops or head straps with both hands, then unfold the mask, making sure it covers your mouth, nose, and chin.

Fixed mask:

Ear-loop style: Loop the ear straps over both ears, adjust the tightness to ensure the mask fits snugly against your face.

Head-mounted: Place the headband over the top of your head and at the back of your neck, then adjust it to a comfortable position.

Press the metal nose clip: Use the index fingers of both hands to press the metal strip at the top of the mask, ensuring it fits snugly against the bridge of your nose to prevent air from leaking in from the top.

Check for a proper fit: Take a deep breath and observe whether the mask rises and falls with your breathing. Also, check around the edges for any air leaks (you can perform a breath test—if you notice airflow escaping around the mask, readjust it accordingly).

4. Avoid touching the outer surface of the mask.

After putting on the mask, try not to touch the outer surface with your hands to avoid contamination by bacteria or viruses.

II. The Correct Way to Remove a Medical Mask

1. Clean your hands

Before removing your mask, wash your hands with soap and running water, or use an alcohol-based hand sanitizer to disinfect them.

2. Removal method

Ear-loop mask: Use both hands to gently remove the mask by pinching the ear loops, avoiding touching the outer surface of the mask.

Head-mounted mask: Hold the bottom of the headband with each hand, and slowly remove the mask from your head, again avoiding contact with the outer surface of the mask.

3. Properly handle masks

Disposable medical masks: Discard immediately after removal into a covered trash bin, and avoid reusing them.

Reusable masks (such as cotton masks): Place them in a dedicated cleaning bag and, upon returning home, wash and disinfect them according to the correct procedure.

4. Clean your hands again.

After removing the mask, immediately wash your hands with soap and running water for at least 20 seconds, or clean your hands with an alcohol-based hand sanitizer.

III. Precautions for Wearing and Removing Masks

1. Avoid frequently touching your mask.

While wearing a mask, try to touch it as little as possible. If you accidentally touch it, wash your hands immediately.

2. Replace your mask promptly.

You should immediately replace the mask if it becomes damp, dirty, or shows a noticeable increase in breathing resistance.

Medical surgical masks are recommended to be replaced every 4 hours. Medical protective masks (such as N95 masks) can be used for a slightly longer period depending on the situation, but should not exceed 8 hours.

3. Precautions for Wearing by Special Populations

Children: Choose a children’s mask that fits the child’s facial shape and ensures a snug fit.

For those with facial hair: Facial hair can compromise the mask’s seal; it is recommended to shave off your beard before wearing the mask.

For those experiencing shortness of breath: If you develop symptoms such as rapid breathing or dizziness after wearing a mask, you should immediately remove it and consult a doctor.

4. Mask Storage and Reuse

Disposable masks: Do not reuse; discard immediately after use.

Reusable masks: When washing, avoid high-temperature steaming or bleach. You can hand-wash them with a neutral detergent and then let them air dry. Alternatively, you can disinfect them using UV light or dry them at high temperatures (make sure to confirm that the mask material is heat-resistant).

IV. Risks Associated with Improper Wearing and Removal Techniques

Touching the outer surface of the mask: The outer layer of the mask may be contaminated with viruses. If you touch it and then don’t wash your hands before touching your mouth, nose, or eyes, you’re more likely to become infected.

Discarding masks at random: Unsealed discarded masks can become vectors for virus transmission.

Reusing contaminated masks: Moist or dirty masks have reduced protective effectiveness and increase the risk of infection.

V. Summary

Correctly putting on and taking off medical masks is a key measure for preventing respiratory infectious diseases. The following principles must be strictly followed:

Clean your hands before putting on the mask, and make sure the mask is intact and fits snugly against your face.

When removing, avoid touching the outer layer and immediately discard or properly dispose of it.

Wash your hands frequently to reduce the risk of virus transmission.

Replace your mask regularly to maintain its protective effectiveness.

Wearing a mask properly not only protects yourself but also reduces the risk of virus transmission, contributing to public health and safety.
