Cotton fluff hazard

Pullman Fire Department responded to several cotton fluff fires on College Hill every year. Starting mid-May to mid-June, the cottonwood trees in town produce extremely light fluff that can accumulate up to six inches or more in sheltered areas, under brushes and in tall grass. Fluff is dangerous because it collects in the same areas as dead organic matter, such as dried leaves and twigs, increasing the chance of a fire.

Once ignited, the fluff burns rapidly and can flash across a yard quickly.

Deputy Fire Marshal Tony Nuttman warned even a dropped cigarette will ignite the cotton fluff. The best way to prevent these fires is to clean up the fluff by wetting it down, then raking it up and disposing of it in a yard waste can.
