STANDARD FOR FIXED GUIDEWAY TRANSIT AND PASSENGER RAIL SYSTEMS. Includes all amendments and changes through Errata, May 11, NFPA - Download as Word Doc .doc /.docx), PDF File .pdf), Text File .txt) or read online. Fire in the underground. NFPA which is the “Standard for Fixed Guideway Transit and Passenger old metro which was constructed before NFPA , which was established in.
The basis of the document providing the minimum life safety from fire and fire protection requirementsstill stands. It is not intended for the document to provide design basis for non-fire events such as explosions or other random acts of sabotage. Freight operations can affect life safety from fire hazards due to concurrent operations.
The increased hazard includes the potential for rapid fire development to fire heat release rates that can exceed those of a non-freight vehicle, with combustible loads that might support fires that burn for days.
The increased hazard also includes non-fire events involving release of materials hazardous to life.
The design process should include information exchange and agreement among the freight operator, the passenger services operator and the authority having jurisdiction. All concurrent freight and passenger uses should be given consideration.
More detailed consideration of the relative life safety from fire hazards is strongly recommended when applied to underground facilities, where the confined nature of the space will magnify the hazards.
Consideration should include implications of concurrent uses for freight systems operated through or adjacent to passenger stations and concurrent uses for freight systems operated through or adjacent to passenger trainways.
Therefore, the system design must consider specific fire scenarios that could occur. Fire location and size are examples of factors that fire scenarios must consider. This scenario occurs from a fire that originates within a station or trainway or the interior passenger compartment of the vehicle.
Example s of interior fire scenarios include the following : a Fire that begins from an incendiary ignition involving the use of accelerants b Trash fire. This scenario occurs as a result of a fire originating outside the passenger compartment of the vehicle and penetrating the exterior of the vehicle. Examples of exterior fire scenarios include the following : a Electrical fire in the station, in the trainway, under the vehicle floor, or on the roof that burns through into the passenger compartment or that causes the vehicle to stop between stations b Trash fire or other type of station, trainway, or under vehicle equipment or floor fire c Fire that occurs from ignition of a fuel spill adjacent to the station, a trainway, or a vehicle involved in a collision.
Consequences can increase if a fire occurs when occupants are as follows : a in a station, trainway, or passenger carrying vehicle that is stationary and unable to more and in a location where egress or rescue access could be hazardous e. Fire scenarios that are appropriate for a particular system vehicle and operating environment could not be applicable to another system vehicle and operating environment.
Nobody is going to do Quickly determine you water supply capabilities with our on-line application for graphing fire hydrant flow test information on a Logritmic Graph N 1. When initial pressures are over 40 psig at the hydrant under test, the rating is to be based on 20 psig residual pressure, observed at the nearest hydrant connected to the same main and when no water is being drawn.
Now you can tap into this lucrative market with innovative fire hydrant meters from Badger Meter.
Welcome to the Catalysts Division of BASF
Fire hydrant flow testing, fire flow tests, and hydrant testing are important ways to measure aspects of a water supply system. Field crews perform a mechanical test, pressure test, and flow test with every fire hydrant on a recurring basis to ensure fire hydrant flow problems are regularly identified and corrected. They are generally known as fire flow tests as the highest demands on the system occur when fighting a fire.
Extrapolated flow at 0 psi, 20 psi or any user defined pressure. What you are seeing is the color assigned to each hydrant to convey how well it performs as a source of water for firefighting and other uses. COM conducts residual fire hydrant flow testing throughout residential, commercial, and private water supply systems. The static and residual readings are taken from it with no water flowing.
These ensure that equipment is in optimal condition. I I recently conducted a hydrant flow test. The author and FireHydrant. I am new to Survey Credit Cards are also now accepted at the 4th St. To find a tapping point, for water supply or for extinguishing fires, or street cleaning is easier said than done. Individual hydrant flow rates for one- and two-family dwellings having a fire area which does not exceed 3, sq ft shall be determined according to Table I, below, of Water line capacity testing: do it right!
The Municipal Posted on August 17, by Jodi Marlin August 16, What most water system operators call hydrant flow or fire flow testing is giving way to a more accurate name for the same process: Line capacity testing. Akron also offers testers, gauges, water flow meters, and other specialized equipment to help departments meet the annual testing requirements for pumps, hoses, and hydrants.
The Hydrant Flow Test Calculator measures the rated capacity at 20 psi of a fire hydrant. Some newspapers will run a press release as is, and others may contact the fire department for additional information and create a news story based on the press release and interviews with fire department personnel.
How a flow test is performed: A fire hydrant flow test is performed for a specific area by using three fire hydrants. Unlimited number of flow test locations and outlets flowed. In most cases this includes water hydrants and dry risers. Summary: This spreadsheet may be downloaded to calculate the results of fire hydrant flow tests.
Hydrant flow tests are required for fire sprinkler design and for water modeling purposes. Available water supply.

A pumper had to be driven away while still connected to a hydrant, tearing the couplings from the hoseline suction. Single or multiple hydrant flow tests per NFPA The standard provides alternative methods in calculating the fire flow and design characteristics for dry-fire hydrants, water reservoir, and fire ponds.
We offer the following online applications to our clients. We urge commercial companies — big and small — to use fire hydrant meters. The Hydrant Flow Test 6. These options are typically utilized when extending the water system is not an option.
Portland Water District Operations Department determines the date and time of a hydrant flow test. Free hydrant flow test calculator that prints a professional single page report with flow graph.
SW office The sprinkler demand has been calculated to the base of the sprinkler riser, and the fire hydrant flow test represents the water supply at the pressure hydrant.
If the flow value of F causes a drop of 5 psi in the system, then a flow of 2F will cause 4 times that loss like doubling the flow in a hose line or a 20 psi drop. We are expanding the existing building and the plan checker has asked for calculations proving we have residual pressure of 20psi for a flow of gpm at the existing hydrant.
When water authorities provide modeled hydrant flow for use in sprinkler system designs, they should be asked how well the hydraulic models are calibrated how the modeled hydrant flow tests compare to actual hydrant flow tests and reduce the modeled hydrant flow test by the percentage difference they observed in their calibration e. A fire hydrant flow test is a process of flowing water out of at least one fire hydrant while obtaining the required pressures static, residual, and pitot needed to calculate the amount of water in gallons per minute GPM that the water system is capable of providing between the tested hydrants.
More precisely, the actual location of the water supply is the point on the water main that is flowing water to where the pressure hydrant connects. Simply attach your portable meter and a hose to an idle fire hydrant and your cash flow begins, every gallon adding new revenue to your bottom line. When running a fire flow model, available pressure and flow is measured at fire hydrants and other points of connection of interest ie connection to building sprinkler system. Sealing of the adhesive strips on each shingle to the shingle beneath is created by heat from sunlight.
These conditions can cause: A. Accelerated shingle weathering B. Deck rot and attic fungus C. Cosmetic blisters on the shingle surface. Atlas will not be responsible for damage to shingles as a result of inadequate ventilation.
Ventilation provisions must meet or exceed current FHA Minimum Property Standards and conform to all building codes and regulations. To best ensure adequate ventilation and circulation of air, a combination of vents at the ridge and eaves should be used.
All roof structures, especially mansard and cathedral type ceilings, must have complete through ventilation from eave area to the ridge area.
FHA Minimum Property Standards require 1 square foot of net free attic vent area for every square feet of attic floor area; or one square foot per every square feet, if vapor barrier is installed on the warm side of the ceiling, or at least one half the ventilation area is provided near the ridge. Solid wood decking must be well seasoned, not over 6" nominal width, and fastened securely to each rafter.
The deck surface must be clean, bare, gap free and flat. Spray foam insulation applied directly to the bottom of the decking will void the warranty.
Atlas shingles may be installed over a roof system containing a radiant barrier material if: 1. Use of these types of radiant barrier would void the shingle warranty. Underlayment must be applied flat and unwrinkled. Shingles should be applied as soon as possible after the application of organic underlayment felt, which is not intended for prolonged exposure.
Atlas recommends that the shingles be applied the same day as the felt underlayment application to avoid wetting and wrinkling. This approved underlayment is a required roof assembly component to maintain a Class A fire rating of the deck assembly. Underlayment end laps shall be staggered 6 feet apart from the adjacent courses. Corrosion-resistant drip edge should be placed over the underlayment at the rake and beneath the underlayment at the eaves.
As an alternative option, a double layer of approved underlayment can be installed over the entire deck surface is required. Expose the first course 17" and continue up the deck with 36" wide strips, lapping each course 19" over the preceding course - providing a 17" exposure.
The following editions for this book are also available...
End laps for low slopes shall be of at least 12" overlap and staggered 6 feet apart. Install drip edge over the underlayment at the rake and beneath the underlayment at the eaves. Cap flashings of sheet metal and base flashings of metal or mineral surfaced roll roofing should be used at vertical surfaces such as chimneys, skylights, vents, walls, etc. All flashings should be sealed with asphalt plastic cement.
The waterproof flashing material must extend up the roof at least 24" beyond the interior warm wall line, and in areas of severe icing, at least up to the highest water level expected to occur from ice dams.We have lot of brands and options to choose from. All roof structures, especially mansard and cathedral type ceilings, must have complete through ventilation from eave area to the ridge area. Andres Giraldo Moreno.
