The inner perimeter will be established to include all the known, observed evidence at that time. Once the inner perimeter is established, Department members will not re-enter to place crime scene evidence markers. If evidence is discovered outside the inner perimeter, a crime scene evidence marker will be placed, when necessary. Show Occupational Safety and Health Administration (OHSA) regulations specify colour coding of barricade tape as follows: 
In addition, the American National Standards Institute (ANSI) has a separate colour scheme for identifying barrier tape:
It’s important to be aware of the different types of barricade tape, especially if you are working on site. If you notice that barrier tape has been tampered with, knocked down, or removed, report it to the job lead immediately as this could result in serious consequences. Most of the safety training courses offered at Irwin's contain additional information about barrier tape and the hazards within them. In Unitech Supplies, we supplies both barrier tapes with wordings and barrier tapes with different colours. The barricade tapes with wordings easy to understand as the instruction such as “DANGER DO NOT ENTER” are clearly indicated on the tapes. However, for barricade tapes that are in different colours combinations (without the wordings), most folks are not aware of the different purposes/protocols behind the different colours. Unknown to most people, there is actually a standard protocol for the usage of different colour combination for barricade tapes and the most widely followed protocol is the 7 colour combinations protocol is specified by OSHA (Occupational Safety and Health Administration) as follows:
For your easy reference, below is a diagram of the protocol: *Additionally, apart from the standard OSHA 7 colour combinations protocol, here are some of the colour combinations that are also very commonly implemented.
Hopes that the above information will be useful to you in the event that you need to install barricade tapes in your workplace/home, otherwise at least the next time you see some barrier tapes being installed, you have a good idea of what does the colours mean. And, if you should have any further queries regarding the barrier tapes that we supplies, please feel free to send us an email at [email protected] Of course, if you are thinking of installing some barricade tapes and would want everyone to immediately know that the area is out of bounds, you may also consider getting our barricade tapes with wordings instead. 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 police, 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. Description[edit]Red-and-white warning tape marking off an unsafe route Barricade tape is made with durable, resilient, tear-proof plastic materials such as polyethylene, polypropylene, or nylon. Different manufacturers offer different sizes and thicknesses of barricade tape. 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 barricade tape designs may be required to comply with regulations, such as the Occupational Safety and Health Administration (OSHA) and American National Standards Institute (ANSI) regulations (when used for purposes subject to regulation by these organizations) in the USA. Barricade 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. Construction tapeThis is used in construction zones to notify people about ongoing construction and that there are possible hazards within the demarcated area. Construction tape usually employs a yellow-black color combination and incorporates printed text, such as "Under Construction", "Caution", "Work Zone", and "Keep Out" (among others). This type of barrier tape is commonly found at the site of renovations, demolition, and minor repairs.Hazard tapeThis is used in locations containing a substantial danger. Examples include electrocution hazards or areas within which there is a risk of exposure to toxic chemicals. In some regions, the specific color combination indicates the type of threat. For example, yellow-black tape may be used to signal the presence of a physical hazard (e.g., a hole), while magenta-yellow can denote a radiation hazard. This type of barrier tape is commonly used in laboratories, production areas, and industrial zones.Traffic control device tapeThis type of barrier tape, as its name implies is used to control traffic, whether foot traffic or vehicle traffic. Traffic control device tapes are used as temporary traffic signal to redirect traffic during parade or whenever a road is closed. These are usually brightly colored, either in solid orange or orange-white combination.Police tape or law enforcement tapeThis type of barrier tape is used to isolate, protect and preserve a crime scene. Police tape is used to notify the public that an investigation is ongoing and that a particular area is restricted. This is usually seen with a yellow-white, yellow-black or blue-white color combination.Firefighter tapeThis serves the same purpose as police tape and hazard tape. Firefighter tape is used to isolate a particular area during or after a fire to keep the public away from fire-related risks (e.g., smoke inhalation, airborne particulate matter, and damaged structures).Foreground (tape) and background colours[edit]The 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. Requirements for barricade tape[edit]The seven OSHA color combinations for barricade tape. Requirements for barricade tape vary according to the health and safety laws of the country or region it is being used in. United States[edit]OSHA and ANSI provide precise specification for barricade tape colors. These are found in OSHA regulations 1910.22[2] and 1910.144[3][failed verification] and ANSI Z535.5-2007, Safety Tags and Barricade Tapes (for Temporary Hazards). However, the dimension, thickness, and materials of the barricade tape are left to the discretion of the manufacturer. OSHA-specified barricade tape colors[edit]
ANSI-specified barricade tape colors[edit]
United Kingdom[edit]Red and white tape (top) or yellow and black tape (bottom) can both be used to mark hazards under UK health and safety regulations Health and safety regulations state that markings should be placed around obstacles or dangerous locations. This includes where any of the following present a risk:
These markings should be made up of alternating red and white or yellow and black stripes of equal size at a 45 degree angle. Barricade tape can be used to satisfy this requirement as long as the tape is "commensurate with the scale of the obstacle or dangerous location in question".[4] What does yellow caution tape mean?Yellow Caution/Warning Tape Indicates:
The area has safety and health concerns of a lower degree. This could range from anything from hoses or cables on the ground, noise, heavy equipment in use, a congested work area and more. Unless the tape states otherwise … yellow tape can mean, “Enter, but proceed with caution.”
Why do cops use yellow tape?Also called “warning tape,” caution tape is a type of plastic tape with a yellow-black combination, which is designed to capture the attention of people who look at it. It's used to secure crime scenes by letting people know that entry will be refused to people who aren't authorized to be in the area.
What is red police tape used for?Effective December 1, 2013, the Crime Scene Investigations unit began using red crime scene tape to identify the inner crime scene within the existing crime scene.
What is red and white caution tape used for?Proguard Barrier Tape is a strong, durable non-adhesive PVC tape used for marking out or cordoning off areas. The highly contrasting coloured stripes serve as a clear visual warning and also present a barrier to areas that require sectioning off.
