Is It Necessary To Sprinkle Fire In An Outdoor Atrium?

Atriums pose unique fire protection and life safety hazards, and sprinkler systems are required for their use in buildings with an atrium. The IBC/IFC 2021 Section 903.3.1.2.1 permits sidewall sprinklers 1″-6″ below structural members and a maximum of 14″ below deck of exterior balconies and open wood joist construction decks. NFPA 13 or 13R sprinkler systems eliminate fire-resistance rating and opening protectives in exterior walls of exterior areas for assisted rescue. Atriums are to be separated from the rest of the building spaces by a 1-hour fire barrier in fully sprinklered buildings, with openings complying with 707.6.

In addition to documented life-safety and building protection benefits, the inclusion of fire sprinkler systems can offer several code benefits, including increased allowable fires. Smoke discharge systems from the atrium to the building’s interior should be considered when designing buildings with an atrium. The IBC does not include sprinkler requirements for exterior spaces except for certain “exterior balconies, decks, and ground floor patios”.

Atriums are required to be provided with both automatic sprinkler protection and a fire alarm system. Both the sprinkler and fire alarm systems must be installed in the entire building, not just that part where the atrium is located. A noncombustible membrane shall be permitted for use as the roof or skylight of any building or atrium of any type. Sprinkler heads should cover all spaces containing fire load, except for those installed at the top of the atrium shaft.

What is the NFPA coverage for sprinklers?

The text provides information on the coverage areas of sprinkler heads in commercial properties, including light hazards, ordinary hazards, and extra hazards. It emphasizes the importance of ensuring that the fire sprinkler suppression system is correct and in good working order to prevent building safety in case of a fire. Total Fire Protection can help with these needs and provide assistance in ensuring the safety of commercial properties.

When to install a fire sprinkler system?

In accordance with the International Building Code (IBC), fire sprinkler systems are a mandatory requirement for buildings exceeding 5, 000 square feet in area. Additionally, such systems are obligatory for high-rise buildings exceeding 75 feet in height and for buildings designed to accommodate large numbers of people, irrespective of whether they meet specific size thresholds. Furthermore, high-rise buildings are required to have sprinkler systems installed.

Where will the fire sprinkler systems be used?

Fire sprinkler systems are crucial in various settings, including industrial facilities, manufacturing plants, public buildings, cultural institutions, and data centers. Industrial settings often contain flammable materials and machinery, which pose significant fire risks. Manufacturing plants require robust fire protection systems to prevent fires and chemical incidents. Public buildings, such as schools and universities, prioritize safety by installing fire sprinkler systems in classrooms, dormitories, and administrative buildings.

Healthcare facilities rely on fire sprinkler systems to protect patients, medical equipment, and critical infrastructure. Specialized environments, such as museums and libraries, house valuable artifacts and documents that must be protected against fire damage. Data centers house sensitive electronic equipment and servers, requiring fire sprinkler systems to prevent downtime and data loss in case of a fire.

Do exterior canopies need to be sprinklered?

In accordance with NFPA 13 or 13R standards, sprinkler systems are required to be installed in all exterior projections or canopies exceeding 4 ft. in width or depth from the building, irrespective of whether they are attached or not. This stipulation is delineated in the NFPA 903. 3. 1. 6 Fire Protection and Life Safety Systems, Exterior Projections/Canopies.

Where should a fire sprinkler system be placed?

Fire sprinkler heads are heat activated and must be located high up on or near the ceiling, unobstructed to provide maximum flow. They cannot be blocked by beams, trusses, soffits, or other building elements. When properly installed, most sprinkler heads have an 8′ coverage radius, which determines how they must be spaced. The NFPA outlines specific spacing requirements for sprinkler heads based on hazard level and pump flow calculations, and may need to be adjusted based on obstructions in the area.

What is the difference between a fire riser and a fire sprinkler system?

A sprinkler riser is defined as a vertical pipe that connects to the main branch of the sprinkler system, transferring water from the source piping to the overhead sprinkler system. It comprises a variety of components, including control valves, check valves, waterflow switches, test drains, and pressure gauges.

Where are sprinklers required for NFPA 13?

NFPA 13R mandates sprinklers in occupied spaces like dwelling units, hallways, and common areas, while allowing areas where fatal fires less frequently start, such as combustible concealed spaces, small bathrooms, and closets, to go without sprinklers. A chart created by fire protection engineer Joe Meyer compares omitted spaces between NFPA 13 and NFPA 13R. The 2018 IBC requires attic protection in NFPA 13R-protected buildings used for occupancy or storage.

NFPA 13R also lowers costs by allowing a lower level of water discharge, resulting in smaller pipe sizes. However, NFPA 13 requires greater density and spacing for sprinklers and attic protection, which can significantly drive costs.

Can a fire sprinkler riser be outside?

The National Fire Protection Association (NFPA) and International Code Council (ICC) do not mandate the provision of a proper riser room for a fire sprinkler system’s risers. However, if a designated room is provided, it must comply with ICC, NFPA, and local codes. The riser room serves as the control center for a building’s fire sprinkler system and is crucial for overall fire protection.

Where do you put sprinklers in a building?

Individual sprinklers, activated by their heat detector, spray water onto fires, covering 9 sq. m. They can be placed in occupied or concealed spaces to prevent unnoticed fires. There are various types of sprinklers, including wet, alternate wet and dry, dry, tail-end alternate systems, pre-action, delayed, and system zones. There are also conventional and spray type sprinklers, ceiling, recessed, concealed type sprinklers, side wall type sprinklers, Early Suppression Fast Response (ESFR) sprinklers, and Enhanced Protection Extended Coverage (EPEC) sprinklers.

How do I know where to put my sprinklers?

In areas with regular winds exceeding 8 mph, sprinklers should be placed in closer proximity, with a spray radius of approximately 90% or less, contingent on the prevailing wind direction and speed.

Where should sprinkler valves be placed?

To locate lost irrigation valves, visualize the layout of the system and note where the wires enter the ground from the main controller. Common locations include the corners of the house or main building, or downstream of the backflow preventer. Underground irrigation valves are illegal in most areas. Probe the likely location to a depth of six to twelve inches and listen for the hollow sound of the buried valve box. Dig carefully to avoid cutting the PVC irrigation pipes or damaging the wires.

Check local city permits to locate irrigation valves and wires. The irrigation system permit application often includes an irrigation blueprint that should indicate the valve location. Follow the wires from the controller in automatic irrigation systems, digging small holes every ten feet to trace the wire. Be careful not to cut the wire, as buried irrigation valve wires rarely run under driveways.

In summary, finding lost irrigation valves involves visualizing the system layout, checking local city permits, following the wires, and digging up a large portion of the lawn.
