Instructions For Using A Full Face Mask

1. Put on the mask, with the nose part on top, and press it tightly against the face;
2. Pull up the upper headband and place it behind the head, then pull the lower headband over the neck and place it on the back of the neck;
3. Place your fingertips at the top of the metal nose and press inward until the part is pressed into the shape of the nose bridge;
4. Cover the mask with both hands and exhale vigorously. If air flows out from the edge of the mask, it indicates improper wearing and requires retraining and repeating the wearing procedure;
5. After finishing work, place the mask in an appropriate place. If the mask is worn out or breathing becomes difficult after wearing it, a new mask should be replaced.
