Figures 11.11 through 11.13 illustrate the type of metal loss responsible for a dozen tube leaks over a 3-month period. Note the highly localized character of the metal loss, as well as the unusual shapes and random orientations of the eroded sites. The sites were located at the inlet end and resulted from the lodgment of debris at the mouth of the tube. Highly localized turbulence created by this debris caused the erosion.

I insist it was not a leak, Judge Shake. The second point I d like to make is that I did not distribute this motion to the reporters. They saw the motion for themselves and asked me about it. What else could I do under the circumstances but give them the facts " (Of course, I could have kept my mouth shut )... 

Compounds not detected or detected in lower-than-expected concentrations. First, make sure that the problem is definitely due to a problem with the model mouth. For example, the cause of the problem may be due to the analytical equipment (e.g., gas chromatograph or mass spectrometer), inconsistencies in the food sample, and/or extraction errors. If volatile compounds are not detected or are detected in far lower-than-expected concentrations, there may be a gas leak somewhere in the system. All connections should be checked with a leak detector as described for the RAS. 

If work must be performed in an atmosphere high in H2S, then the worker must wear breathing equipment. Air must be supplied, and the worker must wear a mask that covers the mouth, nose, and eyes. The mask must be under positive pressure such that any leak is from the mask to the atmosphere and not vice versa. 

Dental amalgam restorations leak small amounts of elemental mercury vapor into the oral cavity of the mouth. The released mercury can be taken up by the saliva and then distributed to various organs and compartments throughout the body. Daily mercury uptake rates from amalgam are estimated to range from 2 to 25 pg Hg/24 h with the worst case individual estimated to have an uptake of 70 pg Hg/24 h. Mercury is a known neurotoxicant and the off-gassing of mercury over time may cause dementia like conditions in some people. 

Angioedema—An allergic reaction characterized by edema of a tissue such as the lips, eyes, mouth, joints or other structures due to leak of fluid from blood vessels. 

The first severe exposure was described in 1952 (Ward et al, 1952 Ward, 1962). A physician was suddenly exposed to a large concentration of sarin. Within seconds he lost consciousness and convulsed. A minute or two later he became apneic. The second case was a subject in an experimental program who had a more severe toxic effect from a small amount of sarin on his abraded skin than others had had (Grob, 1956). A third individual had small leak in his protective mask while working in an atmosphere of sarin (Sidell, 1974). He exited the area, suddenly lost consciousness, convulsed, and became apneic. A chemist was pipetting a solution containing soman and got some in and around his mouth (Sidell, 1974). He went to the medical facility, where he lost consciousness in about 15 min after the exposure. Medical assistance was available almost immediately for all four of these individuals, and ad survived. Cases one (a physician), three (a technician) and four (a chemist) resumed their normal work after 6-8 weeks with no known decrements. The further effects, if any, in case two were not reported. 

Morphine can enter the mammalian body through the lining of the mouth, rectum, and unidentified portions of the intervening section of the alimentary canal (1). The seeming rule that massive doses of morphine are fatal less often than somewhat smaller amounts may mean that none is absorbed from the stomach, and that the first installment of the massive dose to be absorbed from the intestine leads to a closure of the pyloric sphincter so intense that the little morphine leaking past later can be excreted or destroyed about as fast as absorbed, whereas sufficient of a smaller dose may be absorbed from the intestine to initiate a fatal outcome before the pylorus closes. 

A leak occurred around stopper in the mouth of the Erlenmeyer flask in FIGURE 9.1 during the evolution of nitrogen gas. 

Step 7 Step 6 was repeated for leak diameters 5, 10, 15, and 20 mm on the following locations of the exhaust system between the exhaust manifold and catalytic converter (43.7 cm from the exhaust manifold outlet) between the catalytic converter and silencer (138.40 cm from exhaust manifold) very close to the silencer outlet (233.70 cm from exhaust manifold), and muffler mouth (355.60 cm from exhaust manifold)... 

Aftercare Patients should be kept nil by mouth overnight. A contrast esophagogram should be performed the next day to confirm that the fistula or perforation has been completely closed. If contrast medium passes easily through the stent and there is no evidence of a leak, patients can resume a normal diet.
