s-13 COF FDNY study material

occupant use hose

fire hose designed to be used by the buildings occupants to fight incipient fires (early staged fire) prior to the arrival of trained fire fighters or fire brigade members

in use

hose being used during fire suppression or training

Attack Hose

hose designed to be used by trained fire fighters and fire brigade members to combat fire beyond the incipient (beginning) stage

service test

hydrostatic test conducted by users on all in-service hose to determine suitability for continued service

quick opening device

in a dry pipe system there is a delay between the opening of a sprinkler head or standpipe nozzle and the discharge of water. this delay may allow the fire to spread and more sprinkler heads to open. the delay is due to the time required for the air to leave the systems piping. the difficulty may be partly overcome by the installation of a quick opening device

Control Valve

valve controlling flow to water-based fire protection systems. Control valves do not include hose valves, inspectors test valves, drain valves, trim valves for dry pip etc..

water spray

water in a from having a predetermined pattern, particle size, velocity, and density discharge from specially designed nozzles or devices

Deluge Valve

water supply control valve intended to be operated by actuation of an automatic detection system that is installed in the same area as the discharge devices. INTENDED USE IS MANUAL AND AUTO

Class 2 standpipe

this system is designed to be used by the occupants in a building due to the hose diameter being 1 1/2"

gallons per minute (GPM)

typically used to measure fluid flow rate (such as water) or pump capacity. measurement of water flow rate for a pump or a fire standpipe or sprinkler system

Dry Standpipe with No Permanent Water Supply (Manual Standpipe)

under normal conditions this system has no water in the piping. water is pumped into the standpipe system by the fire department. the water is pumped in through the fire department connection. this system cannot be used unless water is supplied by the fire department. a sign must be attached to each of the hose outlets. it should read "dry standpipe for fire department use only". this system is usually in a building that is not heated. special care must be taken when using a dry standpipe system. the nozzle must never be pointed at the fire until all of the air has been drained from the system because then high pressure air would discharge into the fire making it grow

roof manifold

Standpipe systems are used in buildings where it may be difficult for the Fire Department to pump water on the fire. For example, standpipe systems are required in buildings that are over six stories 75 feet in height. A standpipe system may be combined with an automatic fire protection system. may be in horizontal or vertical position and set back between 18in. and 60in. above roof level

pressure control valve (suction side)

a pilot operated pressure reducing valve that may be used with a fire or booster pump designed for the purpose of preventing the incoming water supply pressure from dropping below a set pressure (suction side of pump)

branch line

a pipe system, generally in a horizontal plane, connecting not more than one hose connection with a standpipe

master pressure reducing valve

a pressure reducing valve installed to regulate pressures in an entire fire protection system and or standpipe system zone

Testing

a procedure used to determine the status of a system as intended by conducting periodic physical checks on water based fire protection systems such as water flow tests, fire pump tests, alarm tests, and trip tests of dry pipe or deluge valves. these tests follow the requirements for acceptance testing at intervals specified in the appropriate chapter of NFPA #25, 2002 edition

fire pump

a pump that is a provider of liquid flow and pressure dedicated to fire protection. a fire pump is a part of a fire standpipe systems water supply and can be powered by electric, diesel, or steam. the pump intake is either connected to the public underground water supply piping or a static water source. the pump providers water flow at higher pressure and volume to the standpipe system risers and hose standpipes.

listed device

A fire protection component that has been tested to perform under parameters specified for its use by a nationally recognized testing agency. Underwriter's Laboratory (UL) and Factory Mutual (FM) are the two most common.

Unplanned out of service condition:

A serious defect in the standpipe or sprinkler system including, but not limited to: an empty tank, a break or major leak in the system's water piping, inoperative or shut water supply valves, defective fire department connections, construction related shut downs affecting more than one floor, or complete or partial shut downs of the standpipe system, other than a shut down for a planned removal from service.

wet standpipe system

A standpipe system having piping containing water at all times.

Automatic Standpipe System

A standpipe system that is attached to a water supply capable of supplying the system demand at all times and that requires no action other than opening a hose valve to provide water at hose connections.

fire hydrant

A valve connection on a water supply system having one or more outlets and that is used to supply hose and fire department pumps with water.

yard systems

A yard hydrant system is most often used in large private manufacturing plants or storage buildings. The yard system is often needed because the public water supply does not meet the needs of the fire protection system. The yard system usually has several private water sources supplying the total fire protection system. The total system may have a sprinkler system, hydrants, and a standpipe and hose system installed. The water supply sources are all connected together in the yard system. This allows the water to be directly supplied to any part of the system when needed. Water can be supplied even when one of the supply sources is not working. The combined sources of water keep the water pressure in the system at a high level.

hose size

An expression of the internal diameter of the hose.

Supervisory signal-initiating device

An initiating device, such as a valve supervisory switch, water level indicator, or low-air pressure switch on a dry-pipe or pre-action sprinkler system, that triggers a supervisory signal.

Impairment Coordinator

The person responsible for ensuring that proper safety precautions are taken when a fire protection system is placed out of service. The building owner shall assign an impairment coordinator to comply with the requirements of this section. In the absence of a specific designee, the owner shall be considered the impairment coordinator.

public waterworks connection

The street main supplies water using the water pressure in the public water works system. Sometimes a street main may not be connected to the system if it is located too far away from the building.

Dry Standpipe with a Manual Control Valve

This system is supplied by a public water main. Under normal conditions this system has no water in the piping. The water is not allowed into the standpipe until a control valve is manually operated. The control valve remains closed until a fire occurs. The air in the piping is not under pressure. A pre-action valve prevents the water from entering the system. The valve is automatically opened when a fire detection system discovers that there is a fire. This system is usually used in a building that is not heated.
