28 FEDA News & Views and extracting creosote from the exhausted air stream allows more of the contaminant to be captured, contained, and disposed of before it is exposed to the exhausted air duct line. Cooking with Solid Fuel Commercial fire suppression systems include interlocked gas valves or electri- cal shunt trip circuit breakers to shut off cooking fuel sources, but there are no practical means for "turning-off" soiled- fuel sources other than letting them burn out. Because of significantly increased fire flash hazards and maintenance intervals that need to be applied to wood burn- ing, installation standards (i.e. NFPA 96) require solid-fuel cooking operations have completely segregated exhaust lines from those of non-solid fuel cook- ing appliances. In 1994, NFPA (National Fire Protection Association) adopted a whole new chapter dealing with con- cerns of solid fuel cooking operations including: ➤ Special attention needs to be made with respect to make-up air require- ments of building areas where wood or soiled fuel appliances are used. ➤ When a solid-fuel cooking appli- ance allows effluent to escape from the appliance opening, this open- ing must be covered by a hood and exhaust system that meets the requirements. ➤ Solid-fuel cooking appliances must be installed on floors of non-com- bustible construction that extends 3 feet in all directions from the appli- ance. ➤ Solid-fuel cooking operation will have spark and ember arresters before filtration devices in a hood. ➤ Wall ter mination of solid fuel exhaust systems is not permitted. ➤ Solid-fuel storage will not exceed a one day's supply or be stored in the same room as the solid fuel appli- ance. ➤ Solid fuel will not be stored in the path of ash removal. ➤ All solid-fuel storage areas shall be provided with a sprinkler system meeting the requirements of NFPA 13. In addition, many local health codes require that solid-fuel storage areas be located in a completely separate area from any food storage or preparation. Local building codes and fire depart- ments regulations may require these Foster Frable continued continued on page 30
