Prior to the release of the dispatch order, it is necessary to understand the situation of the site in detail, to hear the opinions of the relevant personnel, to write the contents of the order, and to make the premises correct, complete and clear.
Glasses, also known as eyeglasses or spectacles, are devices consisting of glass or hard plastic lenses mounted in a frame that holds them in front of a person's eyes, typically using a bridge over the nose and arms which rest over the ears. Glasses are typically used for vision correction, such as with reading glasses and glasses used for nearsightedness. Safety glasses provide eye protection against flying debris for construction workers or lab technicians; these glasses may have protection for the sides of the eyes as well as in the lenses. Some types of safety glasses are used to protect against visible and near-visible light or radiation. Glasses are worn for eye protection in some sports, such as squash. Glasses wearers may use a strap to prevent the glasses from falling off during movement or sports. Wearers of glasses that are used only part of the time may have the glasses attached to a cord that goes around their neck, to prevent the loss of the glasses.
The train dispatcher of the railway bureau issued the driving order, and the other contents should not be filled. If incorrect text is not allowed to be altered, should be rewrote after the circle. Use the common traffic scheduling command phrase (see attachment 2), and use no words or phrases to ring out the item number. In the case of any error or omission, the dispatched order must be cancelled and re-issued.
