The color yellow  is used alone or combined with bands of black color, of equal width, inclined 45º degree, with respect to the horizontal to indicate caution or warn about risks in:

* Parts of machines that can hit, cut, electrocute or damage.

* Levels that may cause falls, for example: first and last flight of stairs, edges of platforms.
* Barriers or fences, railings, pillars, poles, protruding parts of installations or artifact that are prolonged within the areas of normal passages and that may be hit or hit.
* Protruding parts of construction equipment or movement of materials bumpers, pens, bulldozers, tractors, cranes, self-elevating foxes.
