Bulk transport units, such as tank cars, cargo tanks (tank wagons), portable tanks, tube trailers, and multi-unit tank car tanks MEDICAL GAS AND MEDICAL DEVICE REGULATIONS Food and Drug Administration In the United States, the Food and Drug Administration (FDA) regulates medical gases as drugs, and other certain compressed gases and gas apparatus as medical devices. Manufacturers of medical gases and medical devices are required to be registered with the FDA and to produce these gases and devices in compliance with FDA regulations.

Such cylinders must not be charged with any gas except acetylene. Required Cylinder Markings Fig. 4-2. A variety of compressed gas cylinder type~. Under the DOT and TC regulations, cylinders must be marked to indicate (1) the specification under which they were made, (2) the service pressure for which they were designed, (3) a serial number of the manufacturer, (4) the symbol of the inspector (if required), and (5) a symbol indicating the manufacturer. The markings are usually stamped into the shoulder of the cylinder (the part sloping up to the neck) or into the valve guard ring welded to the cylinder.

Vaporization begins at point B and is complete at point C. During this process, the temperature, TB , is constant. The amount of heat required for vaporization, r, is represented by the area between line B-C and the saxis (T = 0). The figure shows that the latent heat of vaporization decreases at high pressures, reaching zero at the so-called critical point, K. Above this point, a diffuse transition takes place between liquid and gas phase. Entropy At the beginning of the nineteenth century, Carnot found, while studying thermal engines, that heat could not be converted completely to mechanical work, which should be possible according to the first law of thermodynamics.
