Can the fire hose be changed into other colors?

Most of the fire engines we usually see are red. Why should the fire truck be painted red? There is some scientific truth in this. Sunlight consists of seven colors: red, orange, yellow, green, cyan, blue and purple. Their wavelengths and deflection angles are different. Sunlight shines on objects, and various objects have different absorption and reflection abilities for different wavelengths of light, thus forming various colors. In short, if an object can reflect one or more kinds of sunlight and absorb the rest, it will have the color of reflected monochromatic light or polychromatic light. Among visible light, red light has the longest light wave and the smallest deflection angle, and easily passes through water layers, raindrops, dust and fog. Orange and yellow light is not afraid of obstacles and can penetrate the objects above. Therefore, the fire truck is painted red, so that people can see it from a distance in foggy weather, dusty environment or stormy weather and make way for it, so that it can complete the fire fighting and emergency rescue tasks as soon as possible. Similarly, fire hydrants are required to be red. Although the fire hose is not clearly defined, the surface of the small square hose has been treated with anti-aging. If you change the color, the color of the new road will destroy the original anti-aging coating and accelerate the aging of the fire hose, so you can't change it at will.

Your situation is still unlikely, because 1. The main reason is that the fire hose is painted with color, which reduces the visual alertness. In case it appears, it will be easily ignored, that is, it will not be recognized. In the consciousness of ordinary people, things that put out fires must be red. If you paint it gray, no one will recognize it, and the difference of ideas will lead to great disaster. 2. The secondary reason is that the life of fire hose will be reduced after painting. Maybe it will leak one day.

And the fire protection law doesn't allow you to change color at will. You said that if you change it, you will be fined for rectification within a time limit in case of fire station inspection or property inspection, which is not good.

Although you are the boss and intend to do business, I have to say that life is best safe. Besides, isn't the red fire hose on the ceiling a good sign?
