The Ralston-Purina plant used hexane as a solvent to extract oil from soybeans. The plant employed a containment system designed to recycle used hexane from the process back to the plant. However, the containment system was not functioning that night, and a large quantity of hexane was released into the sewers.
Hexane and other volatile hydrocarbons (petroleum ether) present an aspiration risk. [26] n-Hexane is sometimes used as a denaturant for alcohol, and as a cleaning agent in the textile, furniture, and leather industries. It is slowly being replaced with other solvents. [27] Like gasoline, hexane is highly volatile and is an explosion risk.
BLEVE–fireball, 2008 Toronto propane explosion The following is a list of boiling liquid expanding vapor explosion (BLEVE) accidents. It shows whether the accident occurred during dangerous goods transportation or at a fixed facility, the accident origin (e.g., storage, process reactor, rail tank car, tank truck), the material involved, its amount, the number of fatalities, and whether a ...
A BLEVE–fireball at the Philadelphia Energy Solutions refinery, as rendered by the CSB. A boiling liquid expanding vapor explosion (BLEVE, / ˈ b l ɛ v iː / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that is or has reached a temperature sufficiently higher than its boiling point at atmospheric pressure.
The explosion was one of the worst disasters in both Indianapolis and Indiana history. [43] Approximately 54 people died in the initial explosion, and others later succumbed to their injuries, raising the number of fatalities to approximately 81. [note 4] Among the dead was a former mayor of nearby Lafayette, Indiana. [11]
When including settlements ($2.1 billion), costs of repairs, deferred production, and fines, the explosion is the world's costliest refinery accident. The direct cause of the explosion was the ignition of a heavy hydrocarbon vapor cloud which emanated from raffinate liquids overflowing from the top of a blowdown stack. The source of ignition ...
The suspect in New Orleans killed 14 and injured dozens with a Ford pickup truck. The explosion of a Tesla Cybertruck outside the Trump hotel killed the driver and injured seven others.
Dusts also have upper and lower explosion limits, though the upper limits are hard to measure and of little practical importance. Lower flammability limits for many organic materials are in the range of 10–50 g/m 3, which is much higher than the limits set for health reasons, as is the case for the LEL of many gases and vapours. Dust clouds ...
