The Texas Department of Family and Protective Services says it's especially important to clean outdoor play areas.
The agency says if the retardant is still wet, water should wash it off surfaces. Officials say if it has dried, it might require scrubbing with water or power washing. A mild soap could also be used.
The agency says play structures should then be allowed to dry fully -- giving the structures a few days of sunlight to help break down the remaining chemicals.
The agency says many fire retardants could cause a respiratory tract infection if inhaled, eye irritation or a mild skin reaction.
