wet Incident Business Committee IBC Approved The contractor furnishes all equipment operating supplies.
wet line IOSC Incident Operations Subcommittee Approved A line of water, or water and chemical retardant, sprayed along the ground, and which serves as a temporary control line from which to ignite or stop a low-intensity fire.
wet storage Equipment Technology Committee ETC Approved Fire retardants mixed with water and stored in tanks at air attack bases for immediate use by airtankers.
wet-bulb depression Fire Weather Subcommittee FWS Approved The difference between the wet and dry-bulb temperatures recorded by a psychrometer; used in conjunction with the dry-bulb temperature as a measure of the relative humidity of the air.
wet-bulb temperature Fire Weather Subcommittee FWS Approved The lowest temperature to which air can be cooled by evaporating water into it at a constant pressure when the heat required for evaporation is supplied by the cooling of the air. It is measured by the wet bulb thermometer, which usually employs wetted wicking on the bulb as a cooling (through evaporation) device.
wet-bulb thermometer Fire Weather Subcommittee FWS Approved In a psychrometer, the thermometer with its bulb covered with a jacket of clean muslin which is saturated with distilled water before an observation.

Wildland Urban Interface indicator FRSC Fire Reporting Subcommittee, WMSC WUI Mitigation Subcommittee Approved A flag that indicates if the presence of Wildland Urban Interface (WUI) increased the cost or management complexity of a wildfire.
Work Capacity Test (WCT) Risk Management Committee RMC Approved The Work Capacity Test (WCT) is a test to ensure a person is physically capable of meeting the minimum fitness requirement associated with assigned wildfire or prescribed fire duties as described in the NWCG Standards for Wildland Fire Position Qualifications, PMS 310-1.  Below are the three defined duty levels with examples of associated essential functions:   Arduous Arduous duty field work requires above-average endurance and superior conditioning.  Duties may include an occasional demand for extraordinarily strenuous activity in emergency situations under adverse environmental conditions over extended periods. The pace of work typically is set by the emergency condition.  Essential functions include, but are not limited to: running, walking or hiking, climbing, jumping, twisting, bending, lifting more than 50 pounds, and carrying 45 pounds or more for extended periods over difficult terrain.  Moderate Moderate duty field work requires the average endurance and conditioning of an individual who possesses complete control of all their physical faculties. Occasional demands may be required for moderately strenuous activities in emergencies over long periods. The pace of work is usually set by the current environmental conditions.  Essential functions include, but are not limited to: considerable walking over irregular ground, standing for long periods, lifting 25 to 50 pounds, climbing, bending, stooping, squatting, twisting, and reaching. Light Light duty mainly involves office-type work with occasional field activity characterized by light physical exertion requiring basic good health.  Individuals almost always can govern the extent and pace of their physical activity.  Essential functions include, but are not limited to: climbing stairs, standing, operating a vehicle, and long hours of work, as well as some bending, stooping, or light lifting. The WCT consists of three separate levels of tests which correspond with the three duty types.  The tests are defined as follows: Pack Test - This is a job-related test to determine an individual’s ability to perform the minimum standards of arduous duty.  It consists of completing a 3-mile walk over level terrain in 45 minutes or less while carrying a 45-pound pack.   Field Test – This is a job-related test to determine an individual’s ability to perform the minimum standards of moderate duty. It consists of completing a 2-mile walk over level terrain in 30 minutes or less while carrying a 25-pound pack. Walk Test – This is a job-related test to determine an individual’s ability to perform the minimum standards of light duty.  The test consists of completing a 1-mile walk over level terrain in 16 minutes or less with no load. For more information about the Work Capacity Test consult the Work Capacity Test Administrator’s Guide, PMS 307.
work rate Incident Business Committee IBC Approved A daily, hourly, or mileage rate shall apply when equipment is under hire as ordered by the government and on shift, including relocation of equipment under its own power.
