Safety tags and barricade tapes shall be used to identify a temporary hazard. They shall be used only until such time as the identified hazard is eliminated or the hazardous operation is completed. For example, a safety tag would be appropriate for use during lockout/tagout procedures or use on a damaged tool until the tool can be properly removed from the work area. A barricade tape would be suitable to mark an area affected by a chemical spill or an open and temporary trench. Safety tags or barricade tapes shall not be used in place of a permanent sign or label intended for hazards in normal use, operation, or maintenance. If a permanent sign or label is presented in a tag configuration, it shall comply with the provisions of ANSI Z535.4-2002, or ANSI Z535.2-2002.
