Over 125 increments of heat transfer surface are now available as standard over a range from 3.5 to 2300 square feet. IMPERVITE impervious gra phite tube & shell exchangers are furnished from stocked, component parts to provide quick delivery and mass production economy. Standards can employ either close or open tube spacing, and can have any of 4 types of head design. In IMPERVITE exchangers, corro sives come into contact only with impervious graphite. This material is unaffected by the action of prac tically all corrosives except a few strong oxidizing agents. In addition, it is immune to thermal shock, and possesses a rate of thermal conduc tivity 5 times that of stainless steel. Shells are normally steel, but can be furnished in special alloys, Haveg, IMPERVITE, or can be rubber or lead lined.
DIAPHRAGM
Falls Industries also furnishes the famous IMPERVITE CROSS-BORE and CUBICAL exchangers, as well as centrifugal pumps, absorbers, towers, cascade coolers, rupture disks, pipe, fittings, valves, and special machined components.

tornado might strike any building on the plant site. Feed-back to all plant personnel of lessons learned and weak points which showed up is especially im portant. This may be carried out by asking each plant department to fill out a questionnaire outlining how its unit emergency plan functioned during the hypothetical emergency. Such a questionnaire is shown on page 78 A. The returned questionnaires are studied by the group responsible for the over-all emergency program, answers are consolidated, and a re port is "fed back" to supervisory personnel. Surprise alerts may also be planned, but thorough education prior to running off the exercise is felt to be advisable for the first few hypo thetical emergencies. Simulating fires, explosions, or releases of toxic gases are other dry runs which will serve to educate personnel in cor recting weak spots in their unit plans. This completes the discussions of the six major factors to consider in establishing chemical plant emer gency planning. Errors of omission are recognized and are primarily due to space and time limitations. The development of mutual aid pacts with nearby industries and civil bodies is one area not touched on. Many such pacts have been organized and details have been out lined in several current publications. A realistic appraisal of the po tential emergencies which might develop within your plant is step one in planning. Assigning responsi bility for emergency planning and the development of unit emergency plans make a logical sequence of steps in further development. With a properly thought out ap proach, the plant is less likely to get into trouble; if trouble arises, the plant is better prepared to cope with the emergency.
