Grease buildup is a fire hazard, especially in commercial kitchens where large volumes of food are prepared. According to fire safety experts, hood ducts that are not regularly cleaned are one of the most common causes of restaurant fires. Regular duct cleaning reduces the accumulation of grease, significantly lowering the risk of a dangerous fire. In fact, the National Fire Protection Association (NFPA) recommends that kitchen exhaust systems be cleaned at least every six months, depending on usage.
