NEMA Z535.5-2007 PDF

Scope: 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 lock-out/tag-out 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. 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 Z535.4-2007 or ANSI Z535.2-2007. 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.
