NEW Ei~CGLAND ASSOCIATION OF FIRE CHIEFS Of course, any withdrawal of vapor tends to reduce the pressure by cooling the liquid. Some pressures will not always correspond to the surrounding temperatures, (mless the cylinder is at rest. Now, to take care of that normal working pressure of the cylinder and tank, they are desigiaed with a working pressure, that is, for the 100 pounds, and the smaller cylinder, of 240 pounds per square inch. _And, for the large tanks of 10,000 to 18,000 to 30,000, they are designed for a working pressure of 200 pounds per square inch, or 250, and these cylinders and tanks are properly relieved. So that any excessive build-up of pressure, and that is usually caused by high temperature, for irlstance, such as a cylinder involved in fire, the relief valves, provide for the exit of high pressure. On a cylinder, an ICC cylinder, they are released at about 375 pounds per square inch. This release may be spring-loaded, or it may be a £usable plug, or it may be both. The tendency at the present .time in the industry is to equip cylinder valves with both types of release, the fusible plug and spring-loading. The fusible plug type releases at 165 degrees, which corresponds to the 375 pounds of pressure in the spring-loaded release. The larger vessels, bulk tanks, will contain only spring-loaded release. In addition to the pressure setting requirement, there is also a flow requirement for each individually sized tank, so that the .release value installed will be adequate to take care of the flow under any condition of elevated temperature. The spring-loaded release is only on the larger tanks. They are set to discharge from 100 to 125 per cent of the working pressure of the vessel. So much for tank pressure. Now, we cannot utilize tank pressure in domestic and commercial appliances. Nor is it ever utilized, even on industrial set-ups. Regulating equipment,° installed outside of any building or house, is used to reduce the pressure from whatever the tank pressure may be to a lowstated pressure. This. pressure is measured in inches of water column in the gas industry, and the level of utilization pressure is 11 inches, water column, or about 6½ ounces per square inch, which is a low pressure. The regulating equipment is. also equipped with a relief valve designed to operate at one pound per square inch, and the spring-loading is built in, usually, to the regulating equipment. This prevents, the entrance of any pressure into the dwelling house or store in excess of one pound per square inch, and that, of course, functions only in the event that the regulator is~ not correctly operating. So that there, you have the picture of pressures that we use in the LP industry, not high by standards, industrial comparison of other various stored pressures, air and water pressure in city system, and so forth. The hazard of fire and explosion, of course, is the greatest hazard. That hazard can come about only through the presence o£ an accumulation of unburned fuel, correctly mixed with the right amount of air. With propane, the limits of inflammability are narrow, so that helps us with this particular hazard, and it is difficult to. get a correct mix. As. a matter of fact, when we engineer equipment and appliances, we have to take a bit more care than with the other fuel gases,, because of these narrow limits.
