If available government agencies do not have personnel with the appropriate skills to assist in solving your lAQ problem, they may be able to direct you to firms in your area with experience in indoor air quality work. Note that even certified professionals from disciplines closely related to lAQ issues (such as industrial hygienists, ventilation engineers, and toxicologists) may not have the specific...

This section introduces the important subject of heat and mass transfer to serve as a reference work to both the beginning engineer and the practicing industrial ventilation engineer. 

It is essential that the industrial ventilating engineer have a basic understanding of the properties of water and its treatment. This is to ensure an efficiently running and trouble-free plant. Additional to these issues are the problems relating to the discharge of contaminated water to the surrounding environment. 

Although the table is outside the scope of most industrial ventilating engineering requirements, it does indicate the many problems to be considered in the measurement techniques. 

Since the OELs provide the basis for ventilation requirements, an astute designer tries to find out how secure the OELs of the chemicals which will be used in the plant he or she is planning. Some of the chemicals used may totally lack OELs. Therefore, it is advisable to become familiar with the relevant literature, preferably together with a specialist. It is clear that the ventilation engineer needs to be aware of the possible significance of toxicology for industrial ventilation construction. 

Absorption, distribution, biotransformation, and excretion of chemical compounds have been discussed as separate phenomena. In reality all these processes occur simultaneously, and are integrated processes, i.e., they all affect each other. In order to understand the movements of chemicals in the body, and for the delineation of the duration of action of a chemical m the organism, it is important to be able to quantify these toxicokinetic phases. For this purpose various models are used, of which the most widely utilized are the one-compartment, two-compartment, and various physiologically based pharmacokinetic models. These models resemble models used in ventilation engineering to characterize air exchange.

Robert College, Constantinople Turkey, from 1911 to 1913. On his return to the USA, Allen became dean of his alma mater. In 1918, he was appointed Director of the Bureau of Research of the American Society of Heating and Ventilating Engineers. He passed away unexpectedly at ago of only 51. 

He further submitted his PhD thesis in 1924 to the University of Illinois, Urbana IL. He was at his Alma Mater professor of drawing from 1888-1906, professor of architectural engineering from 1906 to 1912, head of the engineering research division until 1927, and finally from then to 1939 director of the Experiment Station. After retirement, Giesecke was a consultant. He was awarded the 1942 F. Paul Anderson Medal of the Ameriean Soeiety of Heating and Ventilating Engineers ASHVE, whose president he was in 1940. He also was Member ASCE and ASME.

Ventilation. Where it does not prove practicable to use a totally enclosed system, it may be necessary to provide ventilation. The purpose of ventilation is to remove solvent vapours and mists such that they do not enter the breathing zone of personnel. Ventilation engineering is a complex subject, but two broad approaches are available ... 

Downdraft ventilation has been used effectively to contain dusts and other dense particulates and high concentrations of heavy vapors that, because of their density, tend to fall. Such systems require special engineering considerations to ensure that the particulates are transported in the airstream. Here again, a ventilation engineer or industrial hygienist should be consulted if this t)q)e of system is deemed suitable for a particular laboratory operation.
