I would like to ask about the precautions for taking off the mask.

The most important thing is: don't touch the blue surface of the mask, pick the ear hook from behind the ear root and fold the mask backwards, so as to avoid touching the contaminated area of the mask and increase the chance of contacting the virus (see the picture below for details).

Precautions for removing masks

1- Remove the ear hook by hand, and don't touch the contaminated area by hand.

2- Take off the mask and discard it in time. Note that masks are hazardous waste.

3- Remember to wash your hands after throwing away the mask.

In addition, there is a small tip:

After taking off the mask, I will tear the rubber band at the hanging place myself, because I have seen a video before, saying that all children in kindergarten do this. It seems that I am worried that if the mask is not handled properly and flows into the ocean, it will trap marine life, so I have developed the habit of tearing rubber bands at will.

By the way, popularize the precautions for wearing masks.

1- Wash your hands before wearing a mask, and make sure your hands are clean.

2- Pay attention to distinguish the front and back of the mask, with blue facing outwards and white facing inwards. How do you know if it's another color? Look at the picture below, you can judge the positive and negative sides by the rubber band bonding surface of the ear hook. The core is the smooth side to fit the face, and the sticky side is the outside, that's right (see the picture below for details).

3- After wearing, stretch the mask up and down, and press the metal strip at the bridge of the nose to make the mask fit the face.

4- If you need to wear the mask for a long time, it is recommended to change it every 4-6 hours.
