This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a significant increase in the use of composite materials on Air Force, and their use is expected to increase futrther as new weapon systems are fielded. Along with the increased use of composites is an increase in composite repair activities in the Air Force. The Structural Maintenance community has expressed concern over inconsistencies in protective equipment requirements from base to base. The Air Force Research Laboratory's Advanced Composites Support Office (ACSO) routinely finds inconsistencies in engineering controls and protective equipment among composite repair facilities throughout the Air Force. As a result of these concerns, the ACSO requested the Industrial Hygiene (IH) Branch of the Institute for ESOH Risk Analysis (IERA) evaluate advanced composite, fiberglass, and aircraft battle damage repair operations in the Air Force and recommend appropriate protective equipment and engineering controls in order to standardiz procedures and reduce worker exposures. The IH Branch was also asked to determine whether the ground crew ensemble and protective mask provide adequate protection when performing ABDR operations during training for nuclear, biological, and chemical (NBC) environments. This technical report summarizes our recommended sampling methodology, data interpretation, ventilation requirements, personal protective equipment, and workplace practices for composite material repair.

This book was released on 2000 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: "...This study demonstrated that maximum concentrations of selected contaminants in the overhaul atmosphere exceeded occupational exposure limits and could therefore result in adverse health effects in firefighters without respiratory protection. In a variable number of fires, concentrations of acrolein, CO, formaldehyde, and glutaraldehyde exceeded their respective ceiling values; concentrations of sulfur dioxide exceeded the STEL value; and concentrations of coal tar pitch volatiles (PNAs) exceeded the OSHA PEL, ACGIH TLV, and NIOSH REL. The other POCs sampled occurred at concentrations below published occupational exposure limits. Among fires there was tremendous variation in concentrations of the sampled contaminants. This variation may be explained by the diverse nature of each fire, including contents, number of rooms, commercial building versus residential, etc. However, certain contaminants, such as formaldehyde, were found at elevated concentrations at a majority of fires...".

Download or read book Composite Materials in Aircraft Mishaps Involving Fire written by Mark T. Wright and published by . This book was released on 2003-06-01 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: When Navy aircraft are involved in crash incidents, firefighters must be aware of hazards presented by airframe composite-material construction. Composite matrices may be combustible, contributing to the aircraft fuel load and burning hazard. Additionally, fibers released from burning composites may present a respiration hazard to firefighters. Current Navy and military doctrine recognize these hazards; cautionary guidance is provided for composite materials reinforced with carbon/graphite fibers and boron/tungsten fibers. The Naval Air Systems Command (NAVAIR), which provides technical guidance for aircraft fire safety, was concerned that hazards presented by new composite materials and greater quantities of composites may not be adequately addressed in current firefighting and guidance. The objective of this project was to perform a literature search to identify any existing "gaps in knowledge" concerning the role of composite materials in a fire mishap involving an aircraft having composite construction materials. With these "gaps" identified, future actions can be identified, prioritized, and performed.

Kirby and published by . This book was released on 1976 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a project that was undertaken to correlate aircraft fire hazards aground with some quantified airfield parameters involving aircraft operations. The objectives of this study were to explore the feasibility of: (1) correlating aircraft accident/incident history data with airfield operations data in order to characterize aircraft fire hazards which exist in aircraft operations on airfields and (2) developing the criteria needed to assign crash fire suppression equipment to airfields in a manner that reflects the level of an aircraft fire hazard which exists at a given airfield and the capability of specific equipment to deal with the hazards that actually exist.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced composite material (ACM) use in the military and private sector is increasing. As a result, the personnel responding to a crash site should be able to assess the hazard and determine a category of high or low exposure risk. This assessment will take into consideration: visual assessment, duration and location of fire, physical damage, aircraft type/quantity of composite material, terrain and environmental conditions, phase of recovery and type of crash. Personal Protective Equipment (PPE) required to conduct the site clean up will be directed after Site evaluation.

Download or read book The Airliner Cabin Environment and the Health of Passengers and Crew written by National Research Council and published by National Academies Press. This book was released on 2002-01-03 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although poor air quality is probably not the hazard that is foremost in peoples' minds as they board planes, it has been a concern for years. Passengers have complained about dry eyes, sore throat, dizziness, headaches, and other symptoms. Flight attendants have repeatedly raised questions about the safety of the air that they breathe. The Airliner Cabin Environment and the Health of Passengers and Crew examines in detail the aircraft environmental control systems, the sources of chemical and biological contaminants in aircraft cabins, and the toxicity and health effects associated with these contaminants. The book provides some recommendations for potential approaches for improving cabin air quality and a surveillance and research program.
