Be the first person to recommend this.
To understand when a sprinkler system fire department connection (FDC) needs to be supplemented vs supplied, we must first discuss the widely used term, system demand . This term is not defined in any of the fire sprinkler standards, but National Fire Protection Association (NFPA) 13 Standard for the Installation of Sprinkler Systems does require a system to have a hydraulically calculated water demand flow rate, and this term is defined by NFPA 13. The waterflow rate for a system must be calculated using acceptable engineering practices and is commonly referenced as the system demand. 3.3.109 Hydraulically Calculated Water Demand Flow Rate ...

The first half of 2022 has been the busiest six months for the National Fire Sprinkler Association’s Live Fire Sprinkler Demonstration Training Trailer(s). Before we get to the travels of the trailer, let us discuss why the trailers where created and what they can provide. Valve trailers are not a new concept for NFSA as we have many other trailers with different systems installed in them that are located all around the country. The Live Fire Sprinkler Demonstration Training Trailers, as there are two were one of the first projects I worked on after joining NFSA. The concept of the valve trailer is live fire service training, but the trailer has expanded capabilities. ...

Sprinkler Supervision and Monitoring: NFPA 13 and NFPA 72

By John Swanson posted May 24, 2022
Be the first person to recommend this.
Sprinkler Supervision and Monitoring: NFPA 13 and NFPA 72 Part 1 In most cases, the model fire codes used in the United States require new buildings to monitor sprinkler waterflow in accordance with NFPA 72. The International Fire Code (IFC), Section 903.4, requires valves controlling water supply for automatic sprinkler systems to be supervised by a listed fire alarm control unit. NFPA 1 and 101 contain similar requirements. But what does it mean to be electrically supervised in accordance with NFPA 72? What does electrically supervised mean? Electrically supervised means, a listed fire alarm control unit is provided at the protected premises to supervise ...

The Magic Number is Three

By Terin Hopkins posted Apr 25, 2022
Be the first person to recommend this.
The Magic Number is Three Signage Requirements for Fire Department Connections (FDC’s) Frist, we must address who the signage is for, and it’s intended use. The reason for placing signage on a fire department connection (FDC) is to provide the end user or fire department some basic information about the fire protection system installed within a building or structure. This allows them to properly understand what type of system is in the building, pressure requirements needed to properly supplement, or supply that system demand, and which areas are being served during an emergency. Many jurisdictions see this as an opportunity ...

Be the first person to recommend this.
Portable Orchestra Enclosures and Sprinkler Protection Fires in theaters, or more specifically, stages inside theaters, have been a fire problem for hundreds of years. The combination of combustible materials, sources of ignition and lots of people has been a fire safety issue spanning modern time. While the installation of automatic sprinkler systems has saved countless lives and reduced the severity of fires that are happening, unfortunately, the number of fires occurring in assembly occupancies is still too high. To complicate things, architects are constantly introducing new construction features requiring the sprinkler industry to reevaluate protection ...

Tiny Fires in Tiny Homes

By Terin Hopkins posted Mar 15, 2022
Be the first person to recommend this.
One might assume that the size of a home is a direct indication of survivability from fire. The concept is simple, we can safely egress from smaller spaces, but the reality is many of the fire protection features found in larger or more crowded spaces are not applicable to these smaller spaces. This means no fire sprinklers systems, passive fire protection or even early warning systems. That is strange because fires start in the same places regardless of the size of the home and quickly spread toxic gases through the home, no matter the size. In fact, toxic smoke can fill small spaces even faster, with the same rules of physics applying to fire spread and the ...

On November 21, 1980, a fire at the MGM Grand Hotel and Casino in Las Vegas, Nevada took the lives of 85 people and injured over 650. At the time of the fire, 5,000 people were either in the casino or staying in one of the 2,000 hotel rooms. The fire began around 7:00am in one of the first-floor restaurants while most people were asleep in the hotel. The fire spread quickly throughout the 26-story partially sprinklered building. Today, the MGM Grand Fire remains the third deadliest hotel fire in United States history and had a significant impact on building and fire codes throughout the country. One of the most concerning statistics from this fire was, 61 of ...

NFPA 25, Standard for the Inspection Testing and Maintenance of Water-Based Fire Protection Systems , provides the minimum requirements for properly maintaining water-based fire sprinkler systems. Within this standard are several requirements for maintaining proper signage. Many in the industry are unaware of the requirements for proper signage. Of course, the requirements do change from edition to edition. In this blog we will cover the requirements for these signs. Let us start with what is not required. Many technicians cite the building owner for not having signs such as main drain, inspector’s test connection, and alarm line signage. These signs are required ...

NFPA 13 Hose Connections This use of hose connections on sprinkler systems has caused confusion in the fire service by not recognizing that not all hose connections in a building are created equal. Some are hose connections simply installed on sprinkler systems with an added inside hose stream allowance. This allowance only provides a minimal additional water supply not intended to provide the required flow for fire operations. It is intended for ancillary occupant use or for mop-up after a fire Inside hose stream allowance is the amount of additional water that is added to the sprinkler hydraulic calculation design ,  when ...

Understanding Hose Stream Allowance

By Terin Hopkins posted Jan 31, 2022
Be the first person to recommend this.
Hose Stream Allowance Hose stream allowance or demand is the amount of additional water that is added to the sprinkler hydraulic calculation design , when hose connections are added to sprinkler systems. This allowance is not required for most hose connections installed as part of a combined sprinkler-standpipe system using NFPA 14 Standard for the Installation of Standpipe and Hose Systems , designed as a Class I, II or III standpipe system. While sprinklers and standpipes can be supplied by a common riser in combined systems, the hydraulic system demands are done separately to the individual standard. NFPA 14 Section 7.10.1.3.1.1 ...
