Spread Component (SC) (as used in the National Fire Danger Rating System) is a rating of the forward rate of spread of a headfire. [1] Deeming states that "the spread component is numerically equal to the theoretical ideal rate of spread expressed in feet-per-minute."
Flame spread, or surface burning characteristics rating, [1] is a ranking derived by laboratory standard test methodology of a material's propensity to burn rapidly and spread flames. There are several standardized methods of determining flame spread,
Spread Component – Displays a value numerically equivalent to the predicted forward rate of spread of a head fire in feet per minute. It is a function of fuel model characteristics, live fuel moistures , the 0 to 3-inch (76 mm) dead fuel moisture (heavily weighted to the 1-hour timelag fuels), wind speed and slope class .
"Exercise enhanced caution with activities that involve open flames or sparks as fires can easily spread in these weather conditions." Fire warning: National Weather Service warns of 'increased ...
On Tuesday, the fire spread through the Cleveland National Forest and up Santiago Peak, where cameras at multiple communications arrays captured their advance. The timelapse footage shows the ...
A two-alarm fire ripped through a strip mall in south Sacramento’s Parkway neighborhood early Friday morning; Sacramento Fire Department officials and one of the owners called it a total loss.
In a flash fire, the flame spreads at subsonic velocity, so the overpressure damage is usually negligible and the bulk of the damage comes from the thermal radiation and secondary fires. When inhaled, the heated air resulting from a flash fire can cause serious damage to the tissue of the lungs, possibly leading to death by asphyxiation. Flash ...
Business owners worry over lost sales, potential smoke damage. A box alarm sounded at the hotel at 11:37 p.m. on Friday – the start of a fight against flames that would carry on into the night.
