What is NFPA 36?
NFPA 36: Document Scope
1.1 Scope. .1.1* This standard shall apply to the commercial scale extraction processing of animal and vegetable oils and fats by the use of Class I flammable hydrocarbon liquids, hereinafter referred to as “solvents.” A.1.1.1 Extraction processes that use flammable liquids but are not within the scope of NFPA 36 might be within the scope of NFPA 30, Flammable and Combustible Liquids Code, and the user is referred to that document for guidance. (See Chapter 3 for definitions of terms, including “extraction process” and “solvent.”) 1.1.2 This standard shall also apply to any equipment and buildings that are located within 30 m (100 ft) of the extraction process. 1.1.3 This standard shall also apply to the unloading, storage, and handling of solvents, regardless of distance from the extraction process. 1.1.4 This standard shall also apply to the means by which material to be extracted is conveyed from the preparation process to the extraction process. 1.1.5 This standard shall also apply to the means by which extracted desolventized solids and oils are conveyed from the extraction process. 1.1.6 This standard shall also apply to preparation and meal finishing processes that are connected by conveyor to the extraction process, regardless of intervening distance. 1.1.7* This standard shall not apply to the storage of raw materials or finished products. A.1.1.7 See NFPA 61, Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities. 1.1.8 This standard shall not apply to extraction processes that use liquids that are miscible with water. 1.1.9 This standard shall not apply to extraction processes that use flammable gases, liquefied petroleum gases, or nonflammable gases. 1.1.10 This standard shall prohibit the use of processes that employ oxygen-active compounds that are heat or shock sensitive, such as certain organic peroxides, within the area defined in 1.1.2.
This standard provides design, construction, and operational requirements to mitigate fire and explosion hazards in plants involved in the extraction processing of animal and vegetable oils and fats using Class I flammable hydrocarbon liquids. Official document scope
