Available in PDF, EPUB and Kindle. Book excerpt: The Biospecialties Branch, MRMPB, 6570 Aerospace Medical Research Laboratories, initiated a research effort to support and supplement the Air Force Aeronautical Systems Division program concerned with the relationship of microbial contamination to deleterious changes in JP-4 fuel systems. Results of this program have shown the following: the majority of JP-4 fuel systems contain low levels of viable microorganisms; microorganisms are primarily associated with the water phase and rarely with the fuel phase of a JP-4 fuel/water system; JP-fuels exert a toxic effect on viable microbial cells; and microbial corrosion of aluminum alloys 7075 2024, and 7178 can occur in the laboratory but does not appear to be the major cause of corrosion in operational systems. Twenty percent ethylene glycol monomethyl ether (EGME) in a laboratory JP-4 fuel/water-bottom acts as an inhibitor to the majority of viable cells present. As a result of engineering design, it is possible that fuel capacitance probes can cease to operate as a result of microbial growth. Micronic filter materials of phenolformaldehyde impregnated paper can support the growth of microorganisms, but growth even after 43 days is insufficient to cause filter clogging, provided the filter is immersed in fuel. In addition, field surveys of JP-4 fuel handling facilities and aircraft have shown that improved housekeeping and the use of EGME have reduced the quantity of microbial contaminants initially found in the jet systems to an insignificant level.

This book was released on 2003-03-01 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Military aviation fuel systems can be an ideal environment for microorganisms. Microbial growth in hydrocarbon fuel systems arises because of the impracticality of keeping fuel tanks sterile and the inevitable presence of water from condensation. Microbial contaminants in aviation fuel systems are a concern because of their potential to degrade the fuel, accelerate tank corrosion, and threaten flight safety. This research addresses the concern of using more environmentally friendly Fuel System Icing Inhibitors (FSII), which are also biocidal. Are significant levels of microorganisms growing in military aviation fuel systems, and if so, are there any common variables? Forty aviation fuel samples were collected from fuel storage tanks (including flexible expeditionary fuel bladders), refueling trucks, and aircraft from 12 U,S, military bases. Samples were analyzed using peak naming and pattern recognition algorithms of sample extracts processed on a gas chromatograph. Significant levels of microorganisms were found in military aviation fuel systems 90% (36 of 40) of fuel samples produced microbial growth. Over 40% of the serial dilutions that produced microbial growth were characterized as moderately or heavily contaminated samples. The microorganisms isolated were overwhelmingly Gram negative, anaerobic, bacilli with populations varying by orders of magnitude.

This book was released on 1997-09-18 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reduction of the fire hazard of fuel is critical to improving survivability in impact-survivable aircraft accidents. Despite current fire prevention and mitigation approaches, fuel flammability can overwhelm post-crash fire scenarios. The Workshop on Aviation Fuels with Improved Fire Safety was held November 19-20, 1996 to review the current state of development, technological needs, and promising technology for the future development of aviation fuels that are most resistant to ignition during a crash. This book contains a summary of workshop discussions and 11 presented papers in the areas of fuel and additive technologies, aircraft fuel system requirements, and the characterization of fuel fires.

Download or read book Blue Water Navy Vietnam Veterans and Agent Orange Exposure written by Institute of Medicine and published by National Academies Press. This book was released on 2011-07-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 3 million U.S. military personnel were sent to Southeast Asia to fight in the Vietnam War. Since the end of the Vietnam War, veterans have reported numerous health effects. Herbicides used in Vietnam, in particular Agent Orange have been associated with a variety of cancers and other long term health problems from Parkinson's disease and type 2 diabetes to heart disease. Prior to 1997 laws safeguarded all service men and women deployed to Vietnam including members of the Blue Navy. Since then, the Department of Veteran Affairs (VA) has established that Vietnam veterans are automatically eligible for disability benefits should they develop any disease associated with Agent Orange exposure, however, veterans who served on deep sea vessels in Vietnam are not included. These "Blue Water Navy" veterans must prove they were exposed to Agent Orange before they can claim benefits. At the request of the VA, the Institute of Medicine (IOM) examined whether Blue Water Navy veterans had similar exposures to Agent Orange as other Vietnam veterans. Blue Water Navy Vietnam Veterans and Agent Orange Exposure comprehensively examines whether Vietnam veterans in the Blue Water Navy experienced exposures to herbicides and their contaminants by reviewing historical reports, relevant legislation, key personnel insights, and chemical analysis to resolve current debate on this issue.

This book was released on 2020-10-23 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 3.7 million U.S. service members have participated in operations taking place in the Southwest Asia Theater of Military Operations since 1990. These operations include the 1990-1991 Persian Gulf War, a post-war stabilization period spanning 1992 through September 2001, and the campaigns undertaken in the wake of the September 11, 2001, attacks. Deployment to Iraq, Kuwait, Saudi Arabia, Bahrain, Gulf of Aden, Gulf of Oman, Oman, Qatar, the United Arab Emirates, and Afghanistan exposed service members to a number of airborne hazards, including oil-well fire smoke, emissions from open burn pits, dust and sand suspended in the air, and exhaust from diesel vehicles. The effects of these were compounded by stressors like excessive heat and noise that are inevitable attributes of service in a combat environment. Respiratory Health Effects of Airborne Hazards Exposures in the Southwest Asia Theater of Military Operations reviews the scientific evidence regarding respiratory health outcomes in veterans of the Southwest Asia conflicts and identifies research that could feasibly be conducted to address outstanding questions and generate answers, newly emerging technologies that could aid in these efforts, and organizations that the Veterans Administration might partner with to accomplish this work.
