A new office area located inside a warehouse space is being designed as a light hazard occupancy. This office area
may be protected with
A new office area designed as a light hazard occupancy can be adequately protected using standard-response spray sprinklers. These sprinklers are suitable for environments with low fire load densities, such as office spaces.
What is the minimum design criteria to protect an exposed nonexpanded Group A plastic stored in a solid pile to a maximum height of 15 ft (4.6 m) in a 26 ft (7.9 m) high building? Piles to be stable with closed arrays.
To protect exposed nonexpanded Group A plastic stored in a solid pile up to 15 ft high, a design criteria of 0.70 gpm/ft over 2000 ft is typically required. This density and area coverage account for the high combustibility and potential heat release of Group A plastics.
When designing an early suppression fast-response (ESFR) fire sprinkler system, what shall the design area of the most hydraulically demanding area consist of?
The contract document states that the fire sprinkler system must be capable of protecting Cartoned Nonexpanded
Group A plastic stored on wood pallets to a height of 25 ft (7.6 m) under a 35 ft (10.7 m) high ceiling using
K16.8 (240) ESFR sprinklers. What is the minimum operating pressure?
For K16.8 (240) ESFR sprinklers protecting high-piled storage of Cartoned Nonexpanded Group A plastic, a minimum operating pressure of 50 psi is commonly required. This pressure ensures an adequate sprinkler discharge to effectively suppress fires in highly combustible materials.
