Definitions

  • Sprinkler Design Density
  • Water discharged by sprinkler heads (gals), over a

prescribed area (ft²), during a specific period of time (min.)

  • Typical densities range from .10 to .60 gpm/ft²
  • Sprinkler Design Area
  • Large area over which the sprinkler design density is to be

maintained

  • Examples – 1000 to 5000 sq. ft.

15 x 15 = 225 sq. ft. 10 x 10 = 100 sq. ft.

Sprinkler Spacing

branchline

15 ft 15 ft

  • Closer spacing provides heavier water discharge

Design Area (ft²) Any point on curve provides adequate protection

Occupancy Classification

Light Hazard Occupancies Occupancies or portions of other occupancies where the quantity and/or combustibility of contents is low and fires with relatively low rates

  • f heat release are expected

Offers least challenge to sprinkler systems

13 May 2017 OMFPOA Symposium

slide-14
SLIDE 14

Ordinary Hazard (group 1)

Occupancies or portions of other occupancies where combustibility is low, quantity of combustibles is moderate, stockpiles of combustibles do not exceed 2.4m (8ft), and fires with moderate rates of heat release are expected

14 May 2017 OMFPOA Symposium

slide-15
SLIDE 15

Ordinary Hazard (group 2)

Occupancies or portions of other occupancies where quantity and combustibility of contents is moderate, stockpiles do not exceed 3.6m (12ft), and fires with moderate rate of heat release are expected

15 May 2017 OMFPOA Symposium

slide-16
SLIDE 16

Extra Hazard Occupancies

Quantity and combustibility of contents is very high, and flammable and combustible liquids, dust, lint, or other materials are present introducing the probability of rapidly developing fires with high rates of heat release

16 May 2017 OMFPOA Symposium

slide-17
SLIDE 17

Extra Hazard (group 1)

Occupancies include those in which hydraulic machinery or systems with flammable or combustible hydraulic fluids under pressure are present. Rupture and leaks in piping or fittings have resulted in fine spray discharge of such liquids, and intense fires result

17 May 2017 OMFPOA Symposium

slide-18
SLIDE 18

Extra Hazard (group 2)

Occupancies contain more than small amounts of flammable and combustible liquids, usually in

  • pen systems where rapid evaporation can occur

when subjected to high temperatures Also applies when ceiling sprinklers are

  • bstructed by occupancy conditions, not

structural conditions, and water discharged by sprinklers may not reach burning material
