Who knows the design principle and installation method of safety signs? Set the precautions?

I don't know what kind of safety sign you are talking about. There are too many such things, such as traffic, factories, scenic spots and so on.

But the general design principles are similar:

1: Color block selection: General safety signs are colored to distinguish their severity. Like blue = prompt, yellow = warning, red = forbidden. In this way, the three grades are distinguished by color blocks, which is easy to identify. Then the color of the pattern or text is preferably opposite to the background color.

2. Pattern selection: the choice of pattern signs must have certain image significance, such as the sign of no smoking, which even illiterate people can understand, so it is best!

3. Placement location selection: Safety signs are mainly used for reminding and warning, so the placement location must be conspicuous, in front of the incident (the front is just a general finger, like a sign to be careful of slippery roads, and no one can walk through this section until the sign is found. )

The installation method depends on the place of use. But it is generally fixed and not easy to drop!
