1. The CSB determined that changes in DEI’s fireworks __________resulted in the accumulation of a large quantity of explosive components just inside the magazine entrance, creating the essential elements for a mass explosion.
2. According to industry literature, ___________ is extremely sensitive to ignition from small sparks, which can be emitted from static electricity, friction, and electrical contacts, and may explode violently when ignited.
What does the following picture shows?
Layout of the DEI at the time of the incident
Magazine layout at the time of the incident
Workers working in the plant
None of the above
_______________ concluded in its investigative report on the incident that the explosion was likely triggered when loose explosive pyrotechnic powder, initially generated as the fireworks were disassembled outside, spilled or leaked from the boxes onto the storage magazine floor and was ignited due to friction or a metal-to-metal spark as DEI employees moved materials around inside the magazine.
Honolulu Police Department
None of the above
The U.S. Department of Transportation (DOT) hazard classification system regulations classify fireworks as Class 1 explosives due to the hazardous nature of the chemical compositions they contain.
The Activity Hazard Analysis identified which of the following as possible hazards of separating and cutting fireworks that could lead to fire, severe burns, detonation, or death.
All of the above
7. Ordinary plastic garbage bags are sometimes charged with static electricity as part of the manufacturing process in order for the bags to be tightly folded; as such, they are not appropriate for storing explosives.
Post-incident, HIOSH collected 12 separate tools found inside the magazine: three cutting tools, pruning shears, a shovel/dust pan, loppers, a push broom, a pair of miter saws, scissors, tin snips, and a battery-powered diesel pump, Metallurgical testing was conducted to determine if the tools were sparking and thus likely capable of initiating an explosion within the magazine. After the testing which tool was found out to be incapable of producing a spark?
According to the PSM standard, a _________ is conducted to "identify, evaluate, and control the hazards involved" in a process associated with highly hazardous chemicals.
Which of the following is not a principle of inherent safety?
DEI personnel involved in the fireworks disposal activities under the fireworks disposal subcontract have the requisite training and experience needed to safely identify and control the hazards of this type of hazardous work.
_________ is a federal law that regulates non-hazardous and hazardous solid waste.
Neither VSE nor BAI used personnel with the necessary backgrounds and expertise to recognize the hazards associated with DEI’s fireworks disposal work.
For the DEI Investigation, the CSB team developed an accident map (AcciMap), a multi-layered causal diagram that allows for the evaluation of higher level causes at the governmental, regulatory, and societal levels, this diagram includes _________ levels.
No Industry Codes or Standards exist that provide safety guidance on fireworks disposal.
