The design and use of all traffic control devices, including signs, signals, markings, barricades, and other devices, for protection of construction workers must conform to Part 6 of the Manual on Uniform Traffic Control Devices for Streets and Highways (MUTCD) (incorporated by reference, see 1926.6).

Accident Prevention Tags

Tags are temporary signs, usually attached to a piece of equipment or part of a structure, to warn of existing or immediate hazards. They are used only until the identified hazard is eliminated or the hazardous operation is completed.

Accident prevention tags must be used as a temporary means of warning employees of an existing hazard, such as defective tools, equipment, etc. They must not be used in place of, or as a substitute for, accident prevention signs.

For accident prevention tags, employers must follow specifications that are similar to those in Figures 1 to 4 of ANSI Z35.2-1968 or Figures 1 to 8 of ANSI Z535.5-2011, incorporated by reference in 1926.6.
