Abstract
A color coded safety belt or harness to be worn by a person to protect the person from a fall and the method of making and using the belt or harness. The belt or harness is formed of first fibers of a predetermined first color, e.g., optical yellow, and also includes at least one color coded indicator fiber woven therein to indicate the year of the manufacture of the belt or harness. The indicator fiber is of a second color which contrasts with the color of the belt or harness fibers to enable the user of the belt or harness to determine if the belt or harness had been produced more than a predetermined number of years before so that a decision can be made by the user of whether or not to discard the belt or harness due to its age. The second color of the indicator fiber is a predetermined different color than the first color, and is changed in successive years, without repeating the second color.
