Sprinkler Spacing and Positioning
Continuing Education Units (CEU): 0.10
Expected Duration: 1 Hour
This self-paced online course covers the spacing and positioning requirements for sprinkler systems. As technology has advanced, new designs have appeared for specific applications, along with specific rules regarding the location and spacing of the sprinklers.
Upon completion you should be able to:
- List issues and rules that have a bearing on the placement of sprinklers
- Explain the limitations regarding the allowable floor area sprinkler system coverage
- Explain key concepts, including manifolding, thermal sensitivity, deflector positioning and "skipping"
- Explain the concept and allowances that dictate when multiple buildings can be protected by a single sprinkler system
- List the ceiling temperature limitations for ordinary, intermediate and high temperature rated sprinklers
- List the distances and zones for the placement of sprinklers around and near heat-producing appliances and equipment
- Explain how obstructions relate to sprinkler installations
- List and explain the disadvantages of water as a suppression agent
- Explain for each type of sprinkler how to determine the spacing allowances from ceilings and walls and between sprinklers
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
- If occupancy changes take place, the sprinklers in the space may have to be changed accordingly.
- If the ceiling temperature is higher than 100 degrees F in any part of a building, the areas of the building that have the elevated ceiling temperatures are required to be outfitted with sprinklers that have intermediate or higher temperature ratings.
- Extended coverage sprinklers have some very strict spacing rules. The spacing is assigned on the basis of a square coverage area. Also, there is no listing or allowance for extended coverage sprinklers in combustible obstructed construction. Lastly, the spacing allowances are reduced for Extra Hazard and storage arrangements.
- ESFR sprinklers are not designed to control a fire. They are designed to completely suppress the fire.
