What caused the explosion at Imperial Sugar refinery?

The explosion was fueled by massive accumulations of combustible sugar dust throughout the packaging building.

What would have prevented the sugar explosion at the Imperial Sugar refinery?

Imperial Sugar had been aware of the hazard of combustible dust for decades before the accident that also caused 36 injuries, mostly related to burns and many of which were life-threatening, the board said on Thursday. …

Will sugar dust explode?

But when dust from high-energy substances, such as sugar, is allowed to accumulate in closed spaces and happens to ignite, it can cause an explosion. The U.S. Chemical Safety and Hazard Investigation Board invest- igated three major industrial explosions involving combustible powders.

What role did sugar dust particles play in the explosion?

The force of the blast depends on the enclosed room. The chain reaction produced from the ignited sugar dust particles produces energy. This produces compression and expands the volume of the air. When this buildup occurs faster than the flame burns — as can be the case indoors — you have an explosion.

Can dust cause an explosion?

Dust can collect on surfaces such as rafters, roofs, suspended ceilings, ducts, crevices, dust collectors, and other equipment. When the dust is disturbed and under certain circumstances, there is the potential for a serious explosion to occur. The build-up of even a very small amount of dust can cause serious damage.

Where is Imperial Sugar now?

LSR now operates a state-of-the-art sugar refinery on the Gramercy, Louisiana site. Imperial will continue to operate a small-bag processing facility at Gramercy.

Is raw sugar explosive?

Raw sugar has low combustibility characteristics and is unlikely to generate combustible sugar dust. the dust explosion destroyed the facility.

What happens when you put fire on sugar?

If you heat up sugar on the stovetop or in an oven, it will caramelize before it catches fire; this happens as heat drives out water molecules and the sugar molecules link together in long chains. The resulting sticky material takes on a brown color because the sugar is partially burned in the process.

Why does sugar burn so easily?

The simplest sugar is glucose – C6H12O6 which contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. All other sugars are slightly more complex but made up of similar atoms. As with all hydrocarbons, the raw ingredients are very easy to burn. Hydrogen is explosively flammable.

What happens when you add sugar to fire?

Granulated table sugar won’t explode by itself, but it can ignite at high temperatures, depending on the humidity and how quickly it’s heated up. Extreme heat forces sucrose to decompose and form a volatile chemical called hydroxymethylfurfural, which easily ignites and sets the rest of the sugar on fire.

Why does dust explode so violently?

Dust explosions occur when combustible dusts build up in the air and combust rapidly, causing a strong pressure wave to form. They are a deadly hazard in a variety of workplaces, from grain silos to plastics factories. A combustible dust at the right concentration level. Oxygen.

What was the cause of the Sugar Refinery explosion in Georgia?

Investigations by Occupational Safety and Health Administration (OSHA) and the Bureau of Alcohol, Tobacco, Firearms and Explosives also concluded that sugar dust was the fuel for an explosion that could have been prevented. By September 2010, 44 suits had been filed in Chatham County Court against Imperial Sugar and/or its cleaning contractor.

When did the dust explosion at Imperial Sugar happen?

On February 7, 2008, fourteen workers were fatally burned in a series of sugar dust explosions at the Imperial Sugar plant near Savannah, Georgia. This CSB safety video explains how the accident occurred.

How long did it take OSHA to respond to the Sugar Refinery explosion?

OSHA arrived within two hours and the CSB within 48 hours. Other brief investigations were conducted by state firefighters and police and the Bureau of Alcohol, Tobacco]

How did Sheptor survive the Sugar Refinery explosion?

Sheptor, who was in the plant at the time of the explosion, survived only because he was protected by a firewall. Heavy equipment had to be used to shore up the partially collapsed structure before firefighters could enter it to search for victims. Within 24 hours, the explosive substance was identified as sugar dust.
