Determine the Occupancy Class

FS 3311, 3312 – Midterm Project Due October 30th.

Determine the Occupancy Class or Commodity Class and provide the required sprinkler design for protection based on the given parameters. You can utilize the following paragraphs as a format to provide requested information .

(Describe commodity and packaging), a Class I/II/III/IV/Group A Plastic (exposed/cartoned, un/expanded) commodity, is/are stored on wood/plastic pallets (or in solid piles) to a maximum height of XX ft located in XXXXX, which has a maximum roof height of XX ft. The palletized/solid-piled/rack (pick one type) storage occupies an approximate floor area of XXXXX ft².

NFPA 13 requires a sprinkler design of XX gpm/ft² over XXXX ft² (or XX sprinklers at XX psi). The storage area is protected by automatic sprinklers capable of delivering a design of XX gpm/ft² over XXXX ft² (or XX sprinklers at XX psi) based on the current water supply.
