Flagging is a coloured non-adhesive tape used in marking objects. It is commonly made of PVC or vinyl, though wood fibre cellulose-based biodegradable flagging also exists.
Flagging is used in surveying to mark grade levels, utility lines, survey stakes and other boundary markers. [1] Surveyors frequently attach their flagging to wooden stakes or lathes, with writing on it. [1] One side tends to have a long number which they reference in a log book.[ citation needed ] The other side tends to have abbreviations suggesting what the stake marks.[ citation needed ] Choice of colour depends on many factors, and can include availability, and personal preference, or may adhere to some sort of colour code. [1] No colour codes appear to be mandatory or universal, but certain colours do tend to be used for specific purposes.
In forestry flagging is commonly used to mark trees for various purposes. It can be used to mark trees for logging, to mark dangerous or unhealthy trees, to mark invasive species, or to mark saplings. State and National forests often use a wide variety of flagging tape, sometimes even getting specially printed tape when the full range of colour codes is used up.
Flagging is widely used in wildlfire suppression both as a navigational aid for firefighters and to mark trees. When walking to a wildfire a crew may use flagging to flag their way to the fire, both to aid other firefighters in quickly finding the site and so they can find their way back out easily. Specially marked flagging also exists for fire use, imprinted with terms such as "spot fire" or "escape route". Hot pink flagging is considered the best colour for marking escape routes due to its visibility. [2] Lime green is most visible for colour blind people but is less visible for those with full colour vision. [2]
In triage, flagging is used in lieu of a triage tag to mark patients in a mass casualty disaster situation. Four colours of flagging are typically used:
Flagging is used as a navigational aid by hunters, hikers, geocachers, spelunkers, mountain bikers, off-road vehicle users, and for other uses such as paintball.
Flagging tape can be used in the field of crime scene photography to show the trajectory of bullets. [3] It's preferable to string due to the wider thickness and reflectiveness though it is harder to pull tight across long distances. [3]
Orienteering is a group of sports that require navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Originally a training exercise in land navigation for military officers, orienteering has developed many variations. Among these, the oldest and the most popular is foot orienteering. For the purposes of this article, foot orienteering serves as a point of departure for discussion of all other variations, but almost any sport that involves racing against a clock and requires navigation with a map is a type of orienteering.
In medicine, triage is a practice invoked when acute care cannot be provided for lack of resources. The process rations care towards those who are most in need of immediate care, and who benefit most from it. More generally it refers to prioritisation of medical care as a whole. In its acute form it is most often required on the battlefield, or at peacetime when an accident results in a mass casualty which swamps nearby healthcare facilities' capacity.
A climbing wall is an artificially constructed wall with grips for hands and feet, usually used for indoor climbing, but sometimes located outdoors. Some are brick or wooden constructions, but on most modern walls, the material most often used is a thick multiplex board with holes drilled into it. Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practice lead climbing or bouldering.
Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In painting and traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB color model, it is a tertiary colour. It is named after the fruit of the same name.
A buoy is a floating device that can have many purposes. It can be anchored (stationary) or allowed to drift with ocean currents.
Color or colour is the visual perceptual property corresponding in humans to the categories called red, yellow, blue, green, etc.
The flag of the United Nations was adopted on December 7, 1946, and consists of the official emblem of the United Nations in white on a blue background.
The Orsec-Novi plan, or short Novi plan, is a French emergency plan used for a mass casualty incident (mascal), i.e. if an emergency has a significant number of casualties in a limited area. Its aim is to organize the rescue resources to cope with the concentrated casualties. It was formerly called red plan ; "Orsec" stands for "rescue management", and "novi" for "multiple casualties".
This glossary of wildfire terms is a list of definitions of terms and concepts relevant to wildfires and wildland firefighting. Except where noted, terms have largely been sourced from a 1998 Fireline Handbook transcribed for a Conflict 21 counter-terrorism studies website by the Air National Guard.
Road surface marking is any kind of device or material that is used on a road surface in order to convey official information; they are commonly placed with road marking machines. They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses.
Trail blazing or way marking is the practice of marking paths in outdoor recreational areas with signs or markings that follow each other at certain, though not necessarily exactly defined, distances and mark the direction of the trail.
Buff is a light brownish yellow, ochreous colour, typical of buff leather. Buff is a mixture of yellow ocher and white: two parts of white lead and one part of yellow ocher produces a good buff, or white lead may be tinted with French ochre alone.
A navigational aid (NAVAID), also known as aid to navigation (ATON), is any sort of signal, markers or guidance equipment which aids the traveler in navigation, usually nautical or aviation travel. Common types of such aids include lighthouses, buoys, fog signals, and day beacons.
Control of alignment and grade during construction is established through the use of survey stakes. Stakes are generally made of wood in different sizes. Based on the use of the stake they are called alignment stakes, offset stakes, grade stakes, and slope stakes.
An orienteering map is a map specially prepared for use in orienteering competitions. It is a topographic map with extra details to help the competitor navigate through the competition area.
A mass casualty incident describes an incident in which emergency medical services resources, such as personnel and equipment, are overwhelmed by the number and severity of casualties. For example, an incident where a two-person crew is responding to a motor vehicle collision with three severely injured people could be considered a mass casualty incident. The general public more commonly recognizes events such as building collapses, train and bus collisions, plane crashes, earthquakes and other large-scale emergencies as mass casualty incidents. Events such as the Oklahoma City bombing in 1995 and the September 11 attacks in 2001 are well-publicized examples of mass casualty incidents. The most common types of MCIs are generally caused by terrorism, mass-transportation accidents, fires or natural disasters. A multiple casualty incident is one in which there are multiple casualties. However the key difference from a mass casualty incident is that in a multiple casualty incident the resources available are sufficient to manage the needs of the victims. The issue of resource availability is therefore critical to the understanding of these concepts. One crosses over from a multiple to a mass casualty incident when resources are exceeded and the systems are overwhelmed
Wildfire suppression equipment and personnel is part of the science of fire fighting focusing on the use of specialized equipment, training and tactics to effectively control, surround and eventually extinguish a natural cover fire. There are several specially designed tools that through their function and user training, perform specialized tasks that are specific to natural cover firefighting. This is used together in conjunction with the general understanding of the behavior of fire to form a viable plan of attack.
Barricade tape is brightly colored tape 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.
Target indicators, also known as target markers or TI's for short, were flares used by the RAF's Bomber Command during World War II. TI's were normally dropped by Pathfinders onto the target, providing an easily seen visual aiming point for the following "main force" of bombers to aim at. After their introduction, the use of TI's expanded to include en-route markers to gather up lost aircraft, additional TI drops to keep the target lit over long periods, and various changes in technique to address German defences.
