These inspections should\nbe implemented by surveys made semi-annually by professionally\ntrained fire protection engineers. If desired, the Bureau of\nYards and Docks could make such semi-annual surveys and would\nalso train the White House personnel assigned to make weekly\nfire inspections.\n7. AUTOMATIC FIRE ALARM SYSTEM\nMuch is dependent upon the prompt discovery of a fire at\nits start. The existing automatic fire alarm system was\ninstalled in the Executive Mansion for that purpose. Its\noperation results from the rate of temperature rise rather\nthan the attainment of a fixed temperature. It is a funda-\nmental law of physics that air expands when heated. The fire\ndetecting element of this system is air contained lin continu-\nous lengths of small, flexible copper tubing. When the fire\nstarts, the heat causes the air within the tubing to expand.\nThis creates an increased pressure within the tubing which\nforces the flexible diaphragms to make electrical contacts which\ninitiate the alarm.\nA. This intricate and delicately balanced system\nrequires specially trained mechanics for testing\nand maintenance. Because of the special training\nrequired, it is important that a service contract\nproviding for quarterly inspections and tests be\nexecuted with the company which installed the\nsystem.\nB. The automatic fire alarm system should be\nextended to:\n(1) The Executive Office Building.\n(2)\nThe East Wing\n(3) The pipe space back of the kitchen\non the third floor of the Executive\nMansion.\n8.\nFIRE HYDRANT\nA. The fire hydrant in the ground to the north of\nthe East Wing should be made more conspicuous as\nit is now partly hidden by foliage.\n9. EXIT FACILITIES\nA.
