Our Team

Mr. Rapperport is the president of Rapperport Associates, Inc., an engineering consulting company providing comprehensive services in fire and explosion investigation, metallurgical and structural failure analysis and accident reconstruction. With degrees in mechanical engineering from Cornell University and materials science from Stanford University, Mr. Rapperport is well suited to address a wide range of technical issues including fire and explosion investigation, failure analysis, materials science and structural design.

Rapperport Associates provides comprehensive fire investigation services including cause and origin investigation, fire modeling and testing as well as fire protection evaluation and assessment. We can perform complex computer modeling to predict hazards such as radiant heat flux, fire growth, smoke production, fire plume and ceiling jet temperatures and velocities, toxic species production and depth of the hot upper layer. We can model fire growth, steady-state burning and decay for intact and impaired sprinkler system activation. The computer models can also be used to study the effects of ventilation changes, and thus, changes in interior environment conditions as the interior and exterior fire suppression activities are conducted.

Rapperport Associates has been retained on cases totaling billions of dollars in losses since inception in 1974. We have an extraordinarily talented technical group with impeccable credentials. Our team of distinguished engineers and scientists is drawn principally from Massachusetts Institute of Technology, Stanford University and University of California Berkeley and many have doctorates. We combine state-of-the-art computer modeling and laboratory testing with clear and compelling graphics to solve complex technical problems and present the results in an understandable manner.

Dr. Moussa has been the Technical Director of the BlazeTech Corporation, an engineering consulting firm since 1987. For over two decades, he has worked in combustion, fire and explosion in a variety of applications and industries covering R&D, testing of hazardous materials and polymer flammability, fire detection/suppression systems, identification and quantification of new risks, plant audit and safety assessment, accident investigation, and simulation and computer modeling. His forte is bridging the gap between theory and practice to provide innovative and cost- effective solutions to new, one-of-kind problems. He has published one book and over 150 papers and reports.
Previously, he was Senior Consultant at Arthur D. Little, Inc. for ten years, a Research Associate at MIT for two years, and a Visiting Scientist at Factory Mutual Research Corporation for one summer. He received a B.S.M.E. with Distinction from Stanford University in 1971, and the M.S./Ph.D. from MIT (in 1972-76, with both dissertations on fires). He is a registered professional engineer in Massachusetts. Examples of his work are:

• Aircraft and subway systems: Dr. Moussa reviewed the flammability, smoke and toxic properties of existing and candidate materials for seats and panels. He modeled fire growth on a train and passenger escape from a disabled train in a tunnel and evaluated the emergency response systems. He quantified the relative benefits of incorporating an exit shaft, a standpipe, or ventilation fans.
• Airport facility: Dr. Moussa investigated a fire involving the incineration of Volatile Organic Compounds emitted from the regeneration of lubricating oils. He designed an improved incinerator tailored to the intermittent nature of the operation.
• Department of Transportation: Dr. Moussa compared the risks associated with Expandable Launch Vehicles and a variety of industrial and transportation activities. The analysis covered handling, transport, storage and launch operations of liquid hydrogen/oxygen, RP-1, hypergolics and solid propellants.
• Gas Research Institute: Dr. Moussa conducted a city-wide survey of common devices that could ignite a vapor cloud of natural gas. He tested the ignition potential of cigarettes, traffic and street lights, automobiles, doorbell relays, etc.
• Major LNG import terminal: Dr. Moussa estimated a probability of overfilling an LNG tanker truck. Using fault-tree analysis, he related this probability to the failure rates of equipment such as level gages, pressure sensors (etc.) and to operator errors. He identified likely failure modes and means to mitigate them.
• US Army: Dr. Moussa tested a unique electrochemical pad containing magnesium. The effectiveness of major Class D Fire Agents was evaluated. Also, hydrogen (produced by the water-magnesium reaction) was measured and the potential build-up of flammable gas in ventilated enclosures was modeled. The MSDS for this device was revised to incorporate the results of this study.
• Dr. Moussa investigated the fire hazards posed by closely spaced storage racks in warehouses. The burning of large vertical surfaces was tested (singly and in pairs to confine radiation) and was modeled successfully.
• US Coast Guard: Dr. Moussa participated in designing the world’s largest (10,000 gals) LNG spill fire test of its time. Both pool and vapor fires were tested. He analyzed and interpreted the data, identifying salient features of these fires.
• Bureau of Mines: Dr. Moussa assessed hazards associated with coal and metal mining: gob, rib and electrical fires, coal pile self-heating and methane/coal dust explosions. He evaluated safety measures such as rock dusting, oxygen masks and fire curtains.
• US DOT Transportation Systems Center: Dr. Moussa assisted in a study of practical means to improve fire safety in existing and new rail transit vehicles and buses. The project identified fire protection countermeasures in design, operations and training to prevent ignition, contain a fire, or facilitate passenger evacuation.
• Oil/LNG/LPG operations: Dr. Moussa carried out risk analysis studies covering oil/LNG/LPG operations, and shipments of hazardous materials by various transportation systems for a number of commercial clients. He modeled consequences of accidents, developed fault trees and risk profiles, and discussed risk acceptability.
• NASA: DR. Moussa compared the crash fire hazards of aircraft fueled by liquid hydrogen, liquid methane and Jet A. He reviewed historical data to identify the locations and amounts of fuel release. For each release and fuel, he analyzed the potential consequences such as pool fire, fireball and explosion.
• Dr. Moussa has provided technical assistance in the litigation of natural gas explosions, electrical wiring fires, insulation fires, aircraft fires, heating and power generation equipment, and self-heating of coal piles.

Dr. Moussa has been listed in American Men of Science and Who’s Who in the East. He served as chairman of the ASME FACT Division. He is a member of ASME, AIAA, and Combustion Institute and of the honorary societies Phi Beta Kappa, Tau Beta Pi and Phi Eta Sigma. He has received several honors, including the William Littlewood Memorial Lecture Award by SAE/AIAA, Engineer of the Year by AIAA NE Section, best papers by SAE and ASEI, AIAA Distinguished Lecturer and several ASME citations. His forewarning about the risks of aircraft fuel tank fire/explosion prior to the TWA800 and the Concorde disasters has led to him being interviewed by the New York Times, several European newspapers, CBS and BBC.
