Installation position of safety identification plate

Installation location of safety signs The audience of this sign is people who may be exposed to the site. Therefore, the installation position of the sign is particularly important. If it is installed in an unrecognizable or difficult position, the safety sign will lose its warning significance.

Common wrong installation locations are as follows:

1、? Safety signs are installed on the doors of the equipment room or at the entrance of the building. In this case, the angle of the sign will change with the state of the door leaf. When the door leaf is in the open state, the sign faces the side of the door. When viewed from the entrance direction, the sign is vertical and cannot be seen.

2. The installation height of safety signs is too high or too low, and people's habit is to look straight up for the most comfort. Therefore, signs should be installed on the horizon of people's sight. Too high will lead to looking up, too low will lead to looking down, and there will be no good user experience.

At the same time, it is not up to standard. It is worth noting that when the safety signs are arranged in two or three rows, the installation height is different from that in the case of single row, which requires rich experience of on-site construction personnel.

3. Installation sequence of safety signs. The Specification for the Configuration of Safety Production Facilities in Thermal Power Plants (hereinafter referred to as the Specification) clearly stipulates that safety signs should be installed from left to right and from top to bottom in the order of warning, prohibition, indication and prompt, so as to have the best identifiability and the neatest and standardized visual effect.
