Study Notes

Storage Definitions: General (NFPA 13)

Available Height for Storage: Maximum allowable height for storing commodities, ensuring necessary clearances from structural elements and below sprinklers.
Cartoned: Storage method using corrugated cardboard or paperboard to fully enclose products.
Cartoned Records Storage: Classified as Class III, primarily consists of paper records stored in cardboard cartons.
Catwalk: A storage aid resembling a walkway made of open metal grating or solid barriers, used to access elevated storage areas, connected by stairs, not standalone floors.
Clearance to Ceiling: Measurement from the top of stored items to the ceiling above.
Commodity: Collection of products, packaging materials, and containers determining the classification of stored items.
Compact Storage: Storage configuration on solid shelves, depth limited to 36 inches, with a maximum vertical spacing of 30 inches between shelves; no internal vertical flue spaces allowed.

Compartmented: Design featuring rigid dividers in containers that keep products stable under fire conditions.
Container (Shipping, Master, or Outer Container): Strong receptacle designed to secure safe transport of contents without needing additional packaging.
Conventional Pallets: Aids in material handling, designed to support unit loads and allow access for handling devices via openings.
Encapsulation: Packaging method that surrounds a pallet load with a plastic sheet, containing combustible items, or wrapping individual combustible commodities in plastic.
Expanded (Foamed or Cellular) Plastics: Plastics characterized by numerous small cavities reducing density, which may affect flammability.
Exposed Group A Plastic Commodities: Unwrapped plastics that can absorb water or cause significant fire hazards; includes paper-wrapped or encapsulated items.
Free-Flowing Plastic Materials: Plastics that can escape containers in case of fire, potentially filling flue spaces and suffocating flames; includes powders, pellets, and small random-packaged items.
High-Challenge Fire Hazard: Identifies materials with increased risk of fire due to specific characteristics (definition not provided in the text).
