| 释义 |
Barricade tape is brightly colored tape (often incorporating a two-tone pattern of alternating yellow-black or red-white stripes or the words "Caution" or "Danger" in prominent lettering) that is used to warn or catch the attention of passersby of an area or situation containing a possible hazard. It acts as a minor impediment to prevent accidental entrance to that area or situation and as a result enhances general safety. Barricade tape is also known as construction tape or barrier tape or in reference to the safety hazard involved as caution tape, warning tape, danger tape or hazard tape. When used by a police force, the tape is named police tape. The tape is often wrapped and affixed as a visual warning sign and demarcation, for instance against entering a dangerous area, such as an industrial or commercial building site, a roadworks construction site or the scene of an accident[1] or a crime (for crime scene preservation), or against handling inoperative machinery or appliances. DescriptionBarricade tape is made with durable, resilient, tear-proof plastic materials such as polyethylene, polypropylene, or nylon. It is at least 2 mm thick and 3 inches wide.{{citation needed|date=August 2013}} However, different manufacturers offer different sizes and thicknesses of barricade tape. Other common sizes of barricade tape are 2, 4 or 6 inches wide and 4 or 10 mm thick.{{citation needed|date=August 2013}} Barricade tape often has a bright background and pre-printed bold warning text. It is also possible to purchase plain barricade tape and write a custom message on it. However, care should be taken when using custom tape, as all barricade tape designs are required to comply with Occupational Safety and Health Administration (OSHA) and American National Standards Institute (ANSI) regulations (when used for purposes subject to regulation by these organizations). TypesBarricade tape is used according to the color specifications set by OSHA and ANSI. Barricade tape may be use primarily as a safety precaution for various industries and procedures.
Foreground (tape) and background coloursThe choice of colours of barricade tape depends on the contrast with its background, which in the case of the sky, can vary from black to white. To have a reasonable chance of being visible against most backgrounds, the tape needs a light colour (white or yellow) and a darker colour. OSHA and ANSI requirements for barricade tapeOSHA and ANSI provide precise specification for barricade tape colors. These are found in OSHA regulations [https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9714 1910.22] and [https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9793 1910.144]{{Citation needed|reason=Neither 1910.22 nor 1910.144 include the color combinations listed in the 'OSHA-specified barricade tape colors' section below.|date=March 2017}} and ANSI Z535.5-2007, Safety Tags and Barricade Tapes (for Temporary Hazards).
