Phos-check, Fire retardant. 阻燃劑

A DC-10 air tanker drops phos-check on the Gibraltar Fire as firefighters watch from a peak in the Los Padres National Forest above Santa Barbara, California in this handout photo from the Santa Barbara County Fire Department released to Reuters October 29, 2015. The fire burned about 50 acres but had firefighters on high alert as hot, dry Santa Ana winds have returned to southern California.
