Indus trial Hygiene Foundation 14,00 Fifth Avenue Pittsburgh, Penna. Abstract of preliminary report on a Foundation-supported study, "An Evaluation of Present Exhaust Ventilation for the Control of Industrial Health Hazards," by Theodore Hatch and Robert H. Walpole, Jr., Department of Public Health and Preventive Medicine, University of Pennsylvania, presented by Professor Hatch at sixth annual meeting of Industrial Srgiene Foundation held at Mellon Institute, Pittsburgh, NovdSL 1911. Two Important situatj^rav stand out with respect to the present pi in designing: of systems ofventilation: 1. the design is almost/ empirical,* 2. the perfcrttefyS^of systems so designed has not been ted with the control which is produced. There ivne^iJor collec tion and tabulatio^an^osign data, the use of which will provd^e\vid'i2ore exact control of dusts63TvVes, vapors and gases. - 0Cfl t ventilation is applied to nunfaerle trial processes end to of the same process. Because of es encountered, it is stat&xthnt design problems cannot be reduced^ engineering relationships and that since great factors of safety :oyed power consumption is only of secondary interest. Recognizing theL cc of the variable factors involved and the reliance which must be placed up&Fbptevious experience, it seems proper to inquire to .what extent empirical gtfcL<&Sed upon experience, can be translated into more basic data which will hav#=oi^general application. One may also investigate the possibilities of reduc^^p^^rconsisaption without sacrificing efficiency of control. Dust and^S&h&b^ontaminonts are dispersed into the air by definite forces. The function hood is to establish 'countar-forces which will prevent the escape^^^z^Hjontaainant. In a basic engineering approach to the design of exhaustthe forces of dispersion must be recognized and evaluated and related to h#wp^f3rmance. The major o'ojoctive of the proposed investigation is to estab- ^syfa^relationship3. It is recognized, however, that many problems cannot be in this nay and, also, that only a few of all the processes requiring venti- Lon can be studied. A general revision of design procedures and the complete elimination of empirical data are not anticipated. The development of a method of investigation will, in itself, be of value. It is hoped, for example, that through the use of such a method, the manufacturers of contaminant-producing equipment will be able to study the characteristics of their own 'machines and develop standards of ventilation. Such original studies will help to remove the present difficulties encountered in applying ventilation to machines and processes as an after-thought, so to speak. At the outset of this investigation, the recent literature on exhaust ventilation has been collected and a bibliography, arranged by industry or process prepared. The list of references is not complete but sufficiently so to show that the volume of published material is not great. The importance of exhaust ventila tion in the control of industrial health hazards and the cost of installing and operating such equipment are great enough today to warrant a noro complete treatment of the subject. The bibliography is attached. mm REFERENCES ON EXHAUST 7ENTILATI0N 1930-1941 G22hkRAXj Air Dilution In Industrial Ventilation, Part3 I, II, III, IV. W.C.L. Hemeon.
