How close can sprinkler be to wall?

7.5 ft.

from a single wall. Again, normally, standard spray sprinklers can be placed up to 7.5 ft. (2.3 m) from any wall.

How much clearance is required around a sprinkler head?

The minimum vertical clearance between sprinklers and material below shall be 18 inches (45.7cm).

How close can an object be to a sprinkler head?

In a nutshell, NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems says that objects that can block a sprinkler’s spray must be at least 18 inches away from the deflector.

What is the minimum amount of clearance required around fire sprinkler heads Australia?

For this reason the Australian Standard requires a clear space of at least 500mm below the deflector. Even temporary obstructions such as storage boxes and tarps can interfere the discharge pattern of the sprinkler heads and compromise the effectiveness of the system.

How far can a sidewall sprinkler be off a wall?

Sidewall sprinkler deflectors shall be located not more than 6 in. (150 mm) or less than 4 in. (100 mm) from walls on which they are mounted.

What is the minimum distance you can store materials relative to sprinkler heads on walls?

Storage shall be maintained 2 feet (610 mm) or more below the ceiling in non-‐sprinklered areas of buildings or a minimum of 18 inches (457 mm) below sprinkler head deflectors in sprinklered areas of buildings.

What is the 18 inch rule?

The purpose of the “18-inch rule” is to prevent storage or any other obstruction from interfering with the spray of water from a sprinkler head during a fire. It is intended to prevent a situation in which the obstruction is within 18-inches of the ceiling and might be between the sprinkler head and the fire.

What distance is required between objects and sprinklers?

In short the “beam rule” states that there must be at least 1 foot (0.3048 m)of separation between the sprinkler and the obstruction if the deflector is any distance above the bottom of the obstruction.

When should I use sprinkler sidewall?

Sidewall fire sprinklers, as the name suggests, protrude from the side of a wall, as opposed to hanging down from the ceiling. Sidewall fire sprinklers are ideal to use in situations where ceiling access is limited or where freezing is a potential concern.

What is the coverage of a sidewall sprinkler?


Standard spray coverage is up to: Light Hazard = 196 square feet(18,2 sq. m); Ordinary Hazard = 100 square feet(9,3 sq. m)per NFPA 13.

What is the Australian standard for sprinklers?

FP-004 : Automatic Fire Sprinkler Installations.

What is the maximum height of sprinkler head?

The maximum ceiling height shall be 40 ft. The minimum operating pressure shall be either 30 psi or 60 psi based upon the applicable storage and ceiling height for the installation as follows: 30 psi for storage heights up to 25 ft. with a maximum ceiling height of 30 ft.

What is the small room rule NFPA 13?

What is the “small room” rule? NFPA 13 Code allows us to space sprinklers up to 9′-0″ off of a single wall under certain instances.

What is the maximum area a sprinkler can protect?

Minimum and maximum distances between the most common sprinkler heads—and from heads to walls—receive careful attention in NFPA 13. A single fire sprinkler can cover an impressively large area, with modern fire codes allowing a single head to protect more than 200 square feet in some environments.

What is the coverage area of a sprinkler?

Sprinkler Head Distance and Spacing Requirements

Hazard Level Coverage (in sq ft) per Sprinkler Head
Light Hazard (areas with low concentrations of flammable materials) 130-200 sq ft per head
Ordinary Hazard 1 & 2 (areas with moderate concentrations of flammable materials) 130 sq ft per head

How is fire sprinkler coverage area calculated?

In short, to determine the minimum flow from a sprinkler in multiplying the area by the required density, is the actual area of the room used (13′-0″ x 13′-0″ = 169 sqft) or is it computed the same as the maximum area of coverage for a sprinkler by doubling the furthest distance from adjacent walls [(7′-0″ x 2) x (7′-0

How Far Should sprinklers be from house?

When placing your sprinkler heads, keep them for at least 2 feet away from the fences and walls. If you are using a spray-type and if you will use a radius rotor-type heads keep it away for 3 feet or more from the structures.

How do you layout a fire sprinkler system?

Quote from Youtube video: Process building the floor area is 3087 square feet the occupancy hazard classification according to nfpa 13 is ordinary hazard group 2. Lay out the sprinklers.
