Toronto Propane Explosion
The Toronto propane explosion (also known as the Sunrise Propane incident) was a series of explosions and ensuing fire that took place on the morning of August 10, 2008, in the Downsview neighbourhood of North York, Toronto, Ontario, Canada. The explosions occurred at the Sunrise Propane Industrial Gases propane facility, located near Keele Street and Wilson Avenue around 03:50 ET. The blasts caused thousands of people to be evacuated from their homes and cost C$1.8 million to clean up, half of which was paid by the province of Ontario. An employee of Sunrise died in the initial explosions and a firefighter died of cardiac arrest the next day while at the scene. History Sunrise Propane Industrial Gases was a company that sold propane for commercial and home purposes, in addition to other gases such as helium and acetylene. The company had operated under a number of names since at least 1999. In 2002, a company named Sunrise Petroleum was successfully sued by First Choice Petrol ...

Eastern Time Zone
The Eastern Time Zone (ET) is a time zone encompassing part or all of 23 states in the eastern part of the United States, parts of eastern Canada, the state of Quintana Roo in Mexico, Panama, Colombia, mainland Ecuador, Peru, and a small portion of westernmost Brazil in South America, along with certain Caribbean and Atlantic islands. Places that use: * Eastern Standard Time (EST), when observing standard time (autumn/winter), are five hours behind Coordinated Universal Time ( UTC−05:00). * Eastern Daylight Time (EDT), when observing daylight saving time (spring/summer), are four hours behind Coordinated Universal Time ( UTC−04:00). On the second Sunday in March, at 2:00 a.m. EST, clocks are advanced to 3:00 a.m. EDT leaving a one-hour "gap". On the first Sunday in November, at 2:00 a.m. EDT, clocks are moved back to 1:00 a.m. EST, thus "duplicating" one hour. Southern parts of the zone (Panama and the Caribbean) do not observe daylight saving time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helium
Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling and melting point are the lowest among all the elements. It is the second lightest and second most abundant element in the observable universe (hydrogen is the lightest and most abundant). It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and in Jupiter, due to the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Downsview Park
Downsview Park is a large urban park located in the Downsview neighbourhood of Toronto, Ontario, Canada. The park's name is officially bilingual due to it being federally owned and managed, and was first home to de Havilland Canada, an aircraft manufacturer, and later was a Canadian Forces base. The park still contains Downsview Airport. In 1999, the Government of Canada declared it as "Canada's first urban national park." However, unlike the Rouge National Urban Park in eastern Toronto, Downsview Park is managed by the federal Crown corporation Canada Lands Company rather than Parks Canada. History Before the establishment of the aircraft plant and airfield the site was farmland that emerged after John Perkins Bull settled nearby in 1842. Aircraft manufacturing and base The area was first used in 1929 by de Havilland Canada, where it housed the company's Canadian operations.

Emergency Evacuation
Emergency evacuation is the urgent immediate egress or escape of people away from an area that contains an imminent threat, an ongoing threat or a hazard to lives or property. Examples range from the small-scale evacuation of a building due to a storm or fire to the large-scale evacuation of a city because of a flood, bombardment or approaching weather system, especially a tropical cyclone. In situations involving hazardous materials or possible contamination, evacuees may be decontaminated prior to being transported out of the contaminated area. Evacuation planning is an important aspect of business management of which emergency evacuation forms a part. Reasons for evacuation Evacuations may be carried out before, during, or after disasters such as: * Natural disasters ** Eruptions of volcanoes ** Tropical cyclones ** Floods ** Earthquakes ** Tsunamis ** Wildfires/Bushfires * Industrial accidents ** Chemical spill ** Nuclear accident * Transport ** Road accidents ** Tr ...

Multiple-alarm Fire
One-alarm fires, two-alarm fires, three-alarm fires, etc., are categories classifying the seriousness of fires, commonly used in the United States and in Canada, particularly indicating the level of response by local authorities. The term multiple-alarm is a quick way of indicating that a fire is severe and is difficult to contain. This system of classification is used by both fire departments and news agencies. The most widely used formula for multi-alarm designation is based on the number of units, (for example firetrucks, tankers, rescue vehicles and command vehicles) and firefighters responding to a fire; the more vehicles and firefighters responding, the higher the alarm designation. In terms of understanding the relative severity of an incident, the government of Rochester, New Hampshire has reported in a statement that a "typical fire in a small structure will usually require only one or two alarms". In contrast, however, a "large-scale fire in a commercial building w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propane Explosion In North Toronto
Propane () is a three-carbon alkane with the molecular formula . It is a gas at standard temperature and pressure, but compressible to a transportable liquid. A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel in domestic and industrial applications and in low-emissions public transportation. Discovered in 1857 by the French chemist Marcellin Berthelot, it became commercially available in the US by 1911. Propane is one of a group of liquefied petroleum gases (LP gases). The others include butane, propylene, butadiene, butylene, isobutylene, and mixtures thereof. Propane has lower volumetric energy density, but higher gravimetric energy density and burns more cleanly than gasoline and coal. Propane gas has become a popular choice for barbecues and portable stoves because its low −42 °C boiling point makes it vaporise inside pressurised liquid containers (2 phases). Propane powers buses, forklifts, taxis, outboard boat motors, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas Leak
A gas leak refers to a leak of natural gas or another gaseous product from a pipeline or other containment into any area where the gas should not be present. Gas leaks can be hazardous to health as well as the environment. Even a small leak into a building or other confined space may gradually build up an explosive or lethal concentration of gas. Leaks of natural gas and refrigerant gas into the atmosphere are especially harmful due to their global warming potential and ozone depletion potential. Leaks of gases associated with industrial operations and equipment are also generally known as fugitive emissions. Natural gas leaks from fossil fuel extraction and use are known as fugitive gas emissions. Such unintended leaks should not be confused with similar intentional types of gas release, such as: * gas venting emissions which are controlled releases, and often practised as a part of routine operations, or * "emergency pressure releases" which are intended to prevent equipmen ...
