Pennsylvania Terminal Fire Equipment.
Three miles of piping that weighs 425 tons and is equipped with 117 hose connections, 24 roof hydrants and 12 flush hydrants, forms the basis of the thoroughly modern fire protection that has been installed in the new Pennsylvania railroad station in New York, which covers 28 acres of ground. With this equipment it is possible to supply 12 standard fire streams at one time, pouring out 3,000 gallons of water per minute. The water comes from a 20-inch main on Seventh avenue and a 24-inch main on Ninth avenue. These two mains SveTe tapped and cross connections were made with the private 12-inch main in Thirty-first street, between the two avenues. The connections were carried directly to two 1,500-gallon pumps, which have a 16inch suction pipe leading to two storage tanks, which have a capacity of 75.000 gallons. The pumps can be operated singly or in battery, and connect with a 12-inch discharge union to the distributing system. The distributing system comprises two sections. One of these supplies 16 4-inch standpipes inside the building and the other forms a 10-inch loop of gridiron shape that encircles the building. The pumps are housed in a structure separate from the main building, wherein is also the station power plant. All of the pipe is wrought steel. In the station building there are 83 hose connections placed about 80 feet apart, and each is supplied with 100 feet of 2^-inch linen hose and an 18-inch nozzle having a 1-inch discharge. On the track levels there are 3 hose connections on the train platforms and 12 fire hydrants of the flush type in the yards. Each of the platform connections is equipped with 100 feet of linen hose. For the roof hydrants there are connections of 100 feet of rubber-lined hose for each hydrant. Hand and chemical extinguishers are provided for the corridors in the upper floors, there being 75 3-gallon extinguishers in the building, besides which there are 33 extinguishers of the non-freezing type on the track level floor. There are also two 500-feet hose reels, making a total hose equipment, tarpaulins to cover stocks and valuables 500-foot hose reels, making a total hose equipment in the building of 15,000 feet. Outside the building there are six Siamese hose connections on the four street fronts, connected directly with the standpipes and to which the city fire engines can be attached in case anything goes wrong with the apparatus in the building. As a further precaution, the building is equipped with a complete firealarm system of the most improved type, with gongs in centrally located points. This system operates in connection with the 116 alarm boxes placed in the tunnels. The fire brigade, consisting of 25 men, is divided into three companies, including a hose wagon company, a chemical engine company and a standpipe company. There are also five men designated to use the hand extinguishers. On the sounding of an alarm from any of the tunnel boxes, the power in the third rails of the tunnel is automatically cut off. This is regarded as the most complete firelighting equipment of any large structure in the world, coupled with the fact that the building itself is as near fireproof as it is possible to make it.
