Editing The Burning Line (section)

==S==
*'''Safety zone''': An area cleared of flammable material used for escape in the event the line is outflanked or in case a spot fire causes fuels outside the control line to render the line unsafe. In firing operations, crews progress so as to maintain a safety zone close at hand allowing the fuels inside the control line to be consumed before going ahead. Safety zones may also be constructed as integral parts of fuel breaks; they are greatly enlarged areas which can be used with relative safety by firefighters and their equipment in the event of blowup in the vicinity.
*'''Sawyer''': [[Chainsaw]] crew, may also include ‘’’faller’’’ or ‘’’feller’’’ who is qualified to cut down trees or snags, perhaps while the tree or snag is burning.
*'''Secondary line''': Any fireline constructed at a distance from the fire perimeter concurrently with or after a line already constructed on or near to the perimeter of the fire. Generally constructed as an insurance measure in case the fire escapes control by the primary line.
*'''Skidder unit''': Pre-configured tank, pump, hose for attachment to a logging skidder (large 4-wheel-drive tractor with a dozer blade, winch or grapple) to be carried to a fireline.
*'''Slash (logging)|Slash''': Debris resulting from such natural events as wind, fire, or snow breakage; or such human activities as road construction, logging, pruning, thinning, or brush cutting. It includes logs, chunks, bark, branches, stumps, and broken under-story trees or brush.
*'''Slopover''': Fire spreading outside the boundaries of a control line.
*'''Slug''': Humorous pejorative term for those believed to be doing less work than you.  "Heli-slug" for helitack, "camp slug" for fire camp support personnel, "engine slug" for engine crew member, etc. 
*'''Slurry bomber''': See Airtanker.
*'''Smokechaser''': Colloquial term for a wildland firefighter.  Now mostly archaic, except in [[Minnesota]] where state Department of Natural Resources firefighters are officially known by that name.
*'''Smokejumper''': A specifically trained and certified firefighter who travels to remote wildfires by fixed-wing aircraft and parachutes into a jump spot - that may include trees - close to the fire.
*'''Smoldering''': A fire burning without flame and barely spreading.
*'''Spike camp''': Remote camp usually near a fireline, and lacking the logistical support that a larger fire camp would have. 
*'''Spotting''': Behavior of a fire producing sparks or embers that are carried by the wind and which start new fires (spot fires) beyond the zone of direct ignition by the main fire. A cascade of spot fires can cause a blowup.
*'''Strike team''': Specified combinations of the same kind and type of resources, with communications, and a leader.
*'''Suppression''': All the work of extinguishing or confining a fire beginning with its discovery.
*'''Suppression crew''': Two or more firefighters stationed at a strategic location for initial action on fires. Duties are essentially the same as those of individual firefighters.
*'''Surface fire''': Fire that burns loose debris on the surface, which include dead branches, leaves, and low vegetation.
