Do signal persons need to be certified?
While the rule states that signal persons need to be qualified (rather than certified) by a “qualified evaluator” certification by an organization such as NCCCO meets this requirement. Qualification can be either through a third-party qualified evaluator (such as an accredited certification body) or through an employer’s qualified evaluator. All signal persons must be qualified and tested through a written or oral test and a practical test, and the qualification must be documented [§ 1926.1428].
