We often see street cleaners carrying cleaning equipment to pick up rubbish, and they all have the same uniform - orange suit.
Why are all the sanitation suits orange?
Have you ever thought about this question when you walked past them countless times?
I think most people would have no ideas.
Sanitation is to take reflective strip, reflect as its name implies the reflective material on reflective vest has reflective effect produces strong reflection under the irradiation of outside illuminant, the reflective material inside has fluorescent powder and so on material, when the light shines, give birth to diffuse reflection effect, can reflect light so.
In bright environments, human eyes are most sensitive to yellow, and in dim environments, to green.
And because in the industrial safety color, orange is the warning color, so the sanitation workers wearing orange sanitation uniforms, will immediately become the most shining star in the crowd.
Sanitation workers often shuttle in the road, every day before dawn began to work, catch fog or night, visibility is very low.
Orange yellow sanitation clothes with reflective strips, when the lights reflect the clothes will constitute reflective light, can attract the attention of drivers friends.
If change blue or it is gray in foggy day or it is night, cannot cause driver to notice very well, can have certain influence to the safety of worker of sanitation.
