NWCG Glossary of Wildland Fire, PMS 205

Any fire crew composed of prison inmates or wards.

The internal diameter of a tube, conductor, or coupling, as distinguished from its OD (Outside Diameter). Fire hose sizes are classified by a nominal internal diameter.

Weather conditions below the minimum for flight under Visual Flight Rules and therefore requiring the observance of instruments inside the aircraft for controlling flight; generally considered to be less than 1000' AGL and 3 miles distant.

System for airplane landing in which the pilot is guided by radio beams.

Naturally or artificially ventilated structure, constructed to specifications and used to shield weather measuring instruments from direct sunshine and precipitation.

A group of predominantly interactive, electronically delivered training. IMI products include instructional software and software management tools used in support of instructional programs. IMI products are teaching and management tools and may be used in combination or individually. Used individually, not all IMI products can be considered interactive, multimedia, or instructional. However, IMI products, when used in combination with one another, are interactive, multimedia, and instructional. IMI technology is one of the primary technologies to be used in distance learning. 

A product, tool, or IT application that has been designated as the trusted source for wildland fire data. This source may also create and update transactional data for use in other applications. There may be more than one IADS and it can change depending on business process complexity and life cycle. An IADS may be a compilation or subset of data from other authoritative sources. The DLM process ensures sources, limitations, currency, and attributes for the IADS are documented.

An individual who may be assigned to or requested by an incident to serve as the sending unit's representative to oversee the care and treatment of crews, overhead, and equipment assigned to an incident.

Agencies and bureaus may have their own SOR for their data. An ISORs are identified by an interagency business area as the official application source of interagency data. An ISOR is the source that resolves duplicate records that may arise from various IADSs and ensures the data meets defined quality standards before it is included in official historical data sets. An ISOR can be an external source of data used by wildland fire.

A course developed by an interagency, all-hazard subject matter expert group containing the same learning objectives and content as an NWCG developed course. Interchangeable course do not require equivalency determination by a using agency and may have multiple course codes and/or numbers. These courses will be incorporated into IQCS/IQS and credit will be given for the NWCG course. 

Smoke which becomes visible only at intervals.

Load carried inside the fuselage structure of an aircraft.

Allowable aircraft cabin load, in pounds, with full fuel and pilot in calm air at standard atmosphere.

An event dealing with effective and timely support to the wildland fire community by mobilizing resources internationally. This category includes importing and exporting resources.

Assigned resources which have checked in at the incident.

Atmospheric inversion. The departure from the usual increase or decrease with altitude of the value of an atmospheric property. In fire management usage, nearly always refers to an increase in temperature with increasing height. Also, the layer through which this departure occurs (also called inversion layer.) The lowest altitude at which the departure is found is called the base of the inversion.

A tapered thread standard that is used for connecting various sizes of rigid pipe. This standard may be referred to as tapered iron pipe thread (TIPT), National pipe thread (NPT), iron pipe thread (IPT), or iron pipe standard thread (IPS). With tapered thread, the threads and pipe sealant perform the seal at the connection. This is opposed to straight thread connectors which use a gasket to form the seal. 

Field marked true if all approvals are complete. False if otherwise

A status flag indicating whether a resource's location (geometry object/shape) is being updated by a real-time GPS tracking such as AVL (Automated Vehicle Locator).

Indicates that the capability is the primary capability for the equipment or aircraft.

Indicates whether a resource is potentially in conflict with another resource of the same kind, based on the overhead conflict detection rules

Indicates if a treatment or activity Is RTRL or not

A status flag indicating whether a resource is valid for use in Initial Response. Invalid resources should be removed from the data stream

Indicates if the vegetation departure has been entered manually

WUI as defined by the Healthy Forests Restoration Act (HFRA) (Title I, Section 101, Subsection 16)

An unburned area within a fire perimeter.

A line connecting points of equal atmospheric pressure on a weather map.

A line connecting points of equal temperature on a weather map.

Layer through which temperature remains constant with elevation.

A fire treatment type. A prescribed fire to deliberately burn natural or modified concentrations (jackpots) of wildland fuels under specified environmental conditions, which allows the fire to be confined to a predetermined area and produces the fireline intensity and rate of spread required to attain planned resource Management Objectives.

Disposing of cargo, fuel, water or retardant overboard to lighten an aircraft or to improve its stability.

Detailed information needed to complete each task including step-by-step explanations, checklists, diagrams and other relevant information. Job aids are for use by trainees as an on-the-job training tool and as a field operational tool for qualified personnel.

A job hazard analysis identifies hazards associated with work projects and worksites, and identifies protective equipment or modified work procedures needed.

A facility established as the central point of contact for news media and interest parties to coordinate incident information activities at the scene of the incident. Public information officials from all participating federal, state, and local agencies should collocate at the JIC. 

A system that integrates incident information and public affairs into a cohesive organization designed to provide consistent, coordinated, timely information during crisis or incident operations.

Selected landing area for smokejumpers.

Approved protection suit worn for smokejumping.

The range or sphere of authority. Public agencies have jurisdiction at an incident related to their legal responsibilities and authority for incident mitigation. Jurisdictional authority at an incident can be political/geographical (e.g., city, county, state or federal boundary lines), or functional (e.g., police department, health department, etc.). 

The agency having responsibility either geographical or functional, related to their legal responsibilities and authorities.

The agency category having land and resource management responsibility for a specific geographical or functional area as provided by federal, state or local law.

The governmental entity having overall land and resource management responsibility for a specific geographical area as provided by law.
