Scope
This standard sets forth requirements for the design@ application@ and use of safety tags and barricade tapes for temporary hazards. They shall be used only until the identified hazard is eliminated or the hazardous operation is completed. For example@ a safety tag would be appropriate for use during lock-out / tag-out procedures or on a damaged tool until it can be properly removed from the work area. 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. However@ if a permanent sign or label is presented in a tag configuration or a hang tag is used to supplement a permanent safety sign@ the safety tag should comply with the provisions of ANSI Z535.2-2011 or ANSI Z535.4-2011. While this standard addresses safety tags and barricade tapes for temporary hazards@ other tags or tape types are not addressed by this standard. For example@ underground tapes@ permanent tapes@ striped tapes@ and non-skid tapes are not covered by this standard. Purpose The purposes of this standard are: a. to establish a uniform and consistent visual layout for safety tags and barricade tapes; b. to minimize the proliferation of designs for safety tags and barricade tapes; and c. to establish a national uniform system for safety tags and barricade tapes that communicate safety information.
