Port Neal Fertilizer Plant Explosion
The Port Neal fertilizer plant explosion occurred on December 13, 1994 in the ammonium nitrate plant at the Terra International, Inc., Port Neal Complex, south of Sioux City, Iowa, United States. Four workers at the plant were killed by the explosion, and eighteen others were injured. The seven-story building at the seat of the blast was completely destroyed, leaving only a crater, and significant damage was inflicted to the surrounding structures. Four nearby electricity generating stations were disabled by the explosion, and the effects of the blast were felt up to 30 miles away. A high-voltage line running adjacent to the plant and over the Missouri River was damaged, disrupting power in the neighboring state of Nebraska. Two 15,000-ton refrigerated ammonia storage tanks were ruptured, releasing liquid ammonia and ammonia vapors which forced the evacuation of 1,700 residents from the surrounding area.

Central Time Zone (North America)
The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean. Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer, most of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC. The largest city in the Central Time Zone is Mexico City; the Mexico City metropolitan area is the largest metropolitan area in the zone and in North America. Regions using (North American) Central Time Canada The province of Manitoba is the only province or territory in Canada that observes Central Time in all areas. The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time: * Nunavut (territory): western areas (most of Kivalliq Region and part of Qikiqtaaluk Region) * Ontario (province): a port ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Fertilizer Companies Of The United States
A fertilizer (American English) or fertiliser (British English; see spelling differences) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment or hand-tool methods. Historically fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations and byproducts of human-nature industries (i.e. fish processing waste, or bloodmeal from a ...

Disasters In Iowa
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either " natural disasters" caused by natural hazards or "human-instigated disasters" caused from anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw. Examples of natural hazards include avalanches, flooding, cold waves and heat waves, droughts, earthquakes, cyclones, landslides, lightning, tsunamis, volcanic activity, wildfires, and winter precipitation. Examples of anthropogenic hazards include criminality, civil disorder, terrorism, war, industrial hazards, engineering hazards, power outages, fire, hazards caused by transportation, and environmental hazards. Developing countries suffer the greatest costs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Explosions In 1994
An explosion is a rapid expansion in volume associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Supersonic explosions created by high explosives are known as detonations and travel through shock waves. Subsonic explosions are created by low explosives through a slower combustion process known as deflagration. Causes Explosions can occur in nature due to a large influx of energy. Most natural explosions arise from volcanic or stellar processes of various sorts. Explosive volcanic eruptions occur when magma rises from below, it has very dissolved gas in it. The reduction of pressure as the magma rises and causes the gas to bubble out of solution, resulting in a rapid increase in volume. Explosions also occur as a result of impact events and in phenomena such as hydrothermal explosions (also due to volcanic processes). Explosions can also occur outside of Earth in the universe in events su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ammonium Nitrate Disasters
__FORCETOC__ When heated, ammonium nitrate decomposes non-explosively into gases of oxygen, nitrogen, and water vapor; however, it can be induced to decompose explosively by detonation into nitrous oxide and water vapor. Large stockpiles of the material can be a major fire risk due to their supporting oxidation, and may also detonate, as happened in the Texas City disaster of 1947 which led to major changes in the regulations for storage and handling. There are two major classes of incidents resulting in explosions: * In the first case, the explosion happens by the mechanism of shock to detonation transition. The initiation happens by an explosive charge going off in the mass, by the detonation of a shell thrown into the mass, or by detonation of an explosive mixture in contact with the mass. Examples are Kriewald, Morgan, Oppau, Tessenderlo, and Traskwood. * In the second case, the explosion results from a fire that spreads into the ammonium nitrate (AN) itself (Texas City, Br ...

The Columbian
''The Columbian'' is a daily newspaper serving the Vancouver, Washington, and Clark County, Washington area. The paper was published for its first decade (1890–1900) as a four-page daily that was meant as a counterweight to the local Republican newspaper ''The Independent''. Printer Tom Carolan began publication of ''The Vancouver Columbian'' on October 10, 1890. It successfully hedged out daily competition, such as the former Independent, to become the sole daily in the city today. A former weekly ''The Sun'' which published for 39 years prior to going daily; was absorbed by the ''Columbian'' and for a time the paper was published as ''The Vancouver Columbian and the Sun''. It has been owned by the Campbell family since 1921; current president and publisher Ben Campbell is the fourth generation of the family to run the paper. It is the newspaper of record for both Vancouver and Washougal. Members of ''The Columbian''s editorial board are Scott Campbell, Jody Campbell, Ben C ...
