Loss of Containment (LOC) and Process Safety Management (PSM) Investigations (Multiple Locations)

1990-present. Conducted Direct Cause Analysis (DCA) and Root Cause Analysis (RCA) of fires, explosions, and mechanical failures at multiple upstream, midstream, and downstream petrochemical and gas utility facilities (e.g., offshore platforms and loading terminals, tank farms, gas storage reservoirs and pipelines, and oil refineries). Damage Mechanisms investigated have included High Temperature Hydrogen Attack (HTHA), Sulfidation corrosion, Wet H2S corrosion, Hydrogen Fluoride (HF) corrosion and Hydrogen Blistering and cracking. Reviewed compliance and gaps against OSHAs PSM standard (CFR 1910.119), with special emphasis on Process Safety Information (PSI), Mechanical Integrity (MI) and Management of Change (MOC). 

Accidental Ignition, Explosion, or Detonation During Manufacturing, Disassembly, Use, and Destruction of Explosives and Pyrotechnics and Reactive Chemicals

1990-present. Failure analysis and incident investigation of explosives, reactive chemicals, munition, shells, pyrotechnic devices, fireworks, and novelty products during the manufacturing, use and disposal cycles. Projects have included malfunction, sensitivity to stray ignition sources including static electricity, misuse, abuse, improper disposal, and issues related to compliance against Federal regulations and Department of Defense specifications.

Dust Explosion and Flash-fire Investigations and Dust Hazards Analysis

1990-present. Failure analysis of dust explosions related to chemical, metal, agricultural, wood and paper, pharmaceutical, and food processing industries. Risk assessment and hazards analysis consistence with Recognized and Generally Accepted Good Engineering Practice (RAGAGEP) across multiple industry segments.

September 11, 2001, Attack on the World Trade Center in New York City 

The September 11, 2001, attack on the World Trade Center complex in New York destroyed both 110-story towers, as well as surrounding low-rise and subterranean structures due to impact and fire spread from flaming debris. A dispute subsequently developed between the long-term leaseholder for the property and their property insurance carriers regarding the extent of insurance coverage for the loss — was it one "occurrence" or two "occurrences" under the language of the policies? The attack also prompted several questions concerning fire spread, fire protection, and emergency response in high-rise structures. Exponent was retained by the property insurance carriers to evaluate the extent of damage under several hypothetical loss scenarios.

Determined how much damage would have occurred to the property if only a single plane had struck one of the towers. Analyzed the collapse and debris patterns for each tower to assess damage to the sub-grade mechanical, electrical, and plumbing infrastructure and predicted the effects of heavy and light debris impacts on the remaining tower. Analysis included the effects of fire spread, smoke, and dust contamination in the remaining tower, and wind-tunnel studies of the performance of single and twin towers. A computer model (FDS) was used to determine the rate of fire growth and maximum temperatures within a typical office on one floor of the tower. The temperature/time history was then used to evaluate the effect on structural components.

Federal Building Bombing, Oklahoma City, Oklahoma 

On April 19, 1995, a 4,800-pound ammonium nitrate — based (ANFO or AN-Nitromethane) bomb, concealed in a rented truck, exploded 20 feet from the Alfred P. Murrah Federal Building in downtown Oklahoma City. The explosion and partial collapse of the nine-story building killed 168 people and injured several hundred more. During the subsequent investigation, Exponent was retained to determine whether certain additives could render ANFO mixtures inert. Conducted an extensive series of test detonations and demonstrated that these additives were completely ineffective. The results were presented to a Congressional Subcommittee, which determined that these additives should not be required for all future ammonium nitrate manufactured or sold in the United States.

Explosion within a Fluorinated Polymer Manufacturing Facility, Alabama 

A 1999 explosion in the purification area of a fluorinated polymer manufacturing plant in the United States caused fatal injuries to three employees. An additional employee was severely injured. Conducted an engineering investigation of the incident, including an analysis of the runaway chemical reaction that caused the explosion. Concluded that adiabatic compression after high-pressure gas was allowed to impinge against a blind flange created temperatures sufficient to ignite a TFE/air mixture within the system. The initial deflagration provided sufficient energy for a self-sustaining decomposition reaction to propagate within the TFE line into the upstream pressure vessel. Also reviewed the HAZOP performed by the employer that failed to note critical parameters that contributed to the incident.

Ammonium Nitrate Plant Detonations, Port Neal, Iowa 

On December 13, 1994, two massive detonations leveled portions of a Port Neal, Iowa, ammonium nitrate plant owned by Terra Industries. Four plant workers were killed, eighteen others suffered serious injury, and damage to the plant and surrounding community was estimated in the hundreds of millions of dollars. Reviewed the events surrounding the accident, analyzed the plant's process data for reliability, and conducted extensive research regarding ammonium nitrate properties and decomposition mechanisms. Also completed analytical modeling and experimental testing to resolve the conflicting accident theories, and inspected and performed metallurgical analysis of various artifacts from the explosion site. The investigation revealed that the detonations occurred due to unsafe plant operations, including poor maintenance and inadequate employee training. Specifically, plant operators allowed the ammonium nitrate within their 18,000-gallon-capacity neutralizer vessel to become contaminated and highly acidic. Operators then injected superheated steam directly into the neutralizer vessel, precipitating a runaway chemical reaction.

Foundry Dust Explosion, Springfield, Massachusetts 

Conducted an engineering investigation of a series of explosions that destroyed the Shell Mold building at the Jahn Foundry in Springfield, Massachusetts, on February 25, 1999. Determined that the subject explosions were fueled initially by dust dislodged from an overhead exhaust duct or inadvertently dispersed during routine maintenance. A subsequent deflagration (dust explosion) occurred within the exhaust ducts associated with the overhead odor control system. This explosion was fueled by resin-rich deposits of dust within the odor control system.

Abattoir Structural Fire, Montreal, Canada 

Conducted an engineering investigation of the May 20, 1990, fire at the Socofi abattoir (slaughterhouse) in St-Louis de France, Quebec. Retained to determine whether certain Arcoplast panels used in the construction of the abattoir met requirements of the Canadian National Building Code (NBC). Investigated the properties and composition of the Arcoplast panels and conducted experiments to determine flame spread and determine whether the materials exacerbated the fire damage. Determined that the Arcoplast panels were developed in an ad hoc manner after the distributor marketed and received an order for the product from the building developer. The panels did not meet NBC fire safety requirements and were the primary reason for the rapid fire growth and spread within the building.

Chemical Plant Runaway Reaction and Explosion, Baltimore, Maryland 

Led the engineering investigation of the October 1998 explosion and subsequent fire at the Condea Vista plant in Baltimore, Maryland. Determined that the explosion occurred due to a runaway chemical reaction inside a batch reactor, while plant personnel were using high-pressure steam to clean out residual chemicals. Process materials released from the various vessels and process piping, which ruptured in this event, fueled the subsequent fire.

Sodium Azide Explosions 

Investigated several incidents that resulted in the ignition of sodium azide propellant at various manufacturing plants across the U.S. Investigations generally focused on identifying how this strictly controlled material was ignited, assessing over-pressure damage and evaluating existing safety procedures.

Occidental Petroleum Piper Alpha Oil Platform Gas Explosion, North Sea, Scotland 

A 1988 explosion and fire in the Piper Alpha oil platform, located in the North Sea off the coast of Scotland, completely destroyed the structure and resulted in the loss of 167 lives. Exponent participated in the public inquiry conducted by the British government and conducted an independent engineering investigation of the subject explosion. One of the key technical issues was the possibility that leaking natural gas had been ignited by hot metal surfaces associated with a gas turbine. Conducted full-scale tests to determine whether the hot skin of certain turbines that operated on the platform could have caused ignition. Also assessed propane vapor concentrations and modeled the vapor cloud from a postulated leak at an improperly tightened flange.

Turbine Repair Center Dust Explosion, San Francisco, California 

Investigated a fire and explosion that occurred at a powder metallurgy facility at the United Airlines Maintenance Operations Center in the San Francisco International Airport. The explosion caused over $20 million in property damage to the Operations Center and injured two employees. Key technical issues included the reactivity of finely divided metal powder, the design and construction of high-velocity pneumatic material-handling systems, the response of structures to dynamic loading from internal explosions, and electrostatic discharge in partially grounded metal hoses. Also assisted in identifying those pieces of equipment that could be salvaged, and advised on the redesign of the facility to prevent future explosions.

Ammonium Perchlorate Plant Explosion, Henderson, Nevada 

Investigated the large fire and explosions that destroyed the manufacturing facilities of Pacific Engineering and Production Company (PEPCON), one of two U.S. producers of ammonium perchlorate. The largest of five individual explosions at PEPCON was equivalent to 1.5 million pounds of TNT, and another explosion was equivalent to 500,000 pounds of TNT. Served as one of the principal technical experts for PEPCON and addressed such issues as the effect of heat, shock pressure, hydrocarbons, and aluminum on the detonation characteristics of ammonium perchlorate; the response of structures to dynamic loads from external explosions; and the migration of gases and other potential sources of pollutants through the ground.

Chlorine Leak, Henderson, Nevada 

The town of Henderson, Nevada, was evacuated following a chlorine leak at a chemical plant. Exponent FaAA investigated the accident under the observation of several federal and state agencies, including the Occupational Safety and Health Administration, the Nevada Department of Occupational Safety and Health, the Environmental Protection Agency, and the Air Pollution Control Board. During this investigation, assisted in characterizing the failure mode, documented damage to the plant, and developed protocols to prevent reoccurrence of failure. The plant was recertified and is back in full-scale production.

Chemical Process Plant Vapor Cloud Release and Explosion Hazard Evaluation

Evaluated the primary vapor cloud explosion (VCE) hazard at a major petrochemical process facility. Computed emission rates for three identified worst-case scenarios, including a liquid, a vapor, and a two-phase aerosol leak. Performed a dispersion analysis to determine the drift distance of each cloud. Computed the extent and duration of the cloud between the lower explosive limit (LEL) and upper explosive limit (UEL). The VCE clouds in each modeled scenario were ignited with a specified ignition source to determine the worst-case overpressure. Analysis indicated that significant overpressures occurred only when the flammable mixture was either partially confined or obstructed, such as within a dense process area. In open or unconfined areas, the vapor cloud burned but did not produce high overpressures.

Ammonium Perchlorate Plant Dust Explosion, Cedar City, Utah 

Investigated the explosion at the Western Electro-Chemical Company's (WECCO) plant that killed one employee and injured three. The incident was triggered by a fire at the batch house dust collector. The ignition likely occurred due to metal-to-metal friction after an employee used an unauthorized steel-tipped shovel to clear out ammonium perchlorate that had clogged the filters of the dust collector. The fire provided a continuous ignition source for the subsequent dust explosion that propagated via the vacuum lines.

Perforation Gun Detonation, Kenai, Alaska 

Investigated a perforation gun explosion at the Halliburton Industries assembly plant that killed one employee and seriously injured five others. Concluded that the employees accidentally ignited shaped charges that were in contact with the detonation cord within the gun.

Advanced Specialty Gases Explosion, Dayton, Nevada 

Investigated an explosion in a nitrogen trifluoride manufacturing plant that occurred after a change of packing inside a distillation column disturbed the passivation layer within the column. The resulting runaway chemical reaction between cryogenic fluorine, cryogenic nitrogen trifluoride, and unprotected stainless steel destroyed the plant.

Gas Fire and Explosion, New York City, New York 

Investigated the fire and explosion after a 36 inch-diameter, 300 psi natural gas pipeline in the Bronx ruptured. Two people were killed, and an entire city block was virtually destroyed. Determined that an earlier explosion in a nearby underground electrical vault had subjected a 40-year-old Dresser coupling on the pipe to a dynamic load, which subsequently caused its failure and triggered the leak.

Coke and Coal Shiploader Fires, Port of Los Angeles, California 

Investigated two fires that occurred within five months on a coal and petroleum coke shiploader operating at the Los Angeles Port. Determined the fire origin and spread mechanism by analyzing the burn patterns on the shiploader and conducting belt-stretch analysis, laboratory scale combustion tests on coke and coal mixtures, metallurgical examination of the conveyor idlers and bearings, and review of applicable standards. The outer race of a failed bearing from one of the conveyor return idlers reached temperatures over 1100°F, sufficient to ignite coal and coke particles that had migrated into the bearing. The hot embers ignited a significant amount of coal and coke debris that had accumulated in a pocket near the bearing due to the geometry of the conveyor idler frame. This resulting fire ignited the non fire-retardant conveyor belt that was part of the original design. The belt eventually snapped after it caught fire, spreading the fire to other parts of the shiploader and causing extensive damage. Determined that design considerations available to prevent coke and coal accumulations around rotating machinery and conveyors would have minimized the likelihood of subject fires.

Mobile Drill Rig Fire, Alaskan North Slope 

Investigated a fire that destroyed a 2-million-pound, 120-foot mobile oil drilling rig that operated on the North Slope of Alaska. A tire blow out during a routine pad to pad move caused a hydraulic leak at the steering cylinder, which ignited. Factors precipitating this incident included deficient and incomplete system engineering during the initial design of the rig, tires and rims that were under-designed for the expected load, and a hydraulic system that was mounted near the tires and utilized combustible hydraulic fluid. Also reviewed the fire department response to the event and determined that, given the available conditions and access to fight this fire, their response was completely appropriate.

Explosion and Fire at Natural Gas Processing Facility, McDonald Island, California 

Investigated a major explosion and fire at the McDonald Island natural gas processing facility that caused extensive damage to the facility. The complex provided access to 75 billion cubic feet of natural gas stored beneath the Sacramento Delta. Determined that the root cause of the explosion was a failure within a high-pressure natural gas tank due to mechanical failure of certain components under high loading stresses.

Venezuelan Natural Gas Pipeline Rupture and Fire 

Investigated the rupture of a high-pressure, 20 inch-diameter natural gas transmission pipeline in Venezuela in September 1993. The subsequent ignition of the gas jet caused an inferno that killed at least 50 people. Key technical issues included evaluating the effect of external mechanical damage from trenching equipment on pipe integrity, flame height and radiation flux on adjacent roadway, pipeline material fracture toughness, critical flaw size, and pipe siting and burial requirements.

Gas Explosion in Apartment Complex, Santa Clara, California 

Investigated the 1996 natural gas explosion that destroyed a 15-apartment complex in Santa Clara, California. The three two-story buildings in this complex had been tented for termite fumigation. For various reasons, the gas supply to the building was not turned off properly, and the main gas regulator was left pressurized. Determined that the regulator diaphragm failed, and the gas accumulated inside the tents. The resulting explosion and fire completely destroyed the complex.

Gas Explosion, San Francisco, California

Investigated the June 1994 explosion and fire at 901 Post Street that killed three people and destroyed a three-story building in San Francisco. The alleged cause of the explosion was damage to a natural gas service line by third parties, which allowed natural gas to enter the building basement. Key technical issues included explosion over-pressure calculations for the basement and first floor to determine whether this was an underground or above-ground explosion, inspection and evaluation of various natural gas appliances in the basement, analysis of alternative fuel sources and ignition mechanisms (including pilot lights, sewer gas, and various possible volatile liquid contaminants), evaluation of the mechanical and physical properties of the pipeline, installation practices, and construction of the building.

Candle Fires 

Analyzed product design and usage data for a unique line of clear, fragranced candles that are used in homes across the nation. Conducted experimental and analytical studies to address the potential risk of fire and injury to consumers. Conducted long-duration, continuous-burn tests to investigate the propensity for flashover. Inspected the candle manufacturing process and conducted in-situ sampling of the raw materials to identify potential contamination scenarios and quantify the risk of flashover and possible injury to the end user. Exponent also conducted consumer tests of the warning label that is currently on the candle and proposed changes based on American National Standards Institute (ANSI) recommendations.
