Transcript of Chemistry

- Considered an industrial disaster

- Often, but not always occur with an explosion

-Usually occur in plants that deal with Petro-chemicals


Industrial Fires
Toxic Chemicals and Atmospheric Contaminants Produced by Domestic and Industrial Fires
Past Incidents/History
Main goal is to contain and eliminate the fire by means of :
Water sprinkler system
Foam
Gas
Dry chemicals
Protection
Only one of the 3 elements need to be controlled
Most common fuel for a flame is dust
A combination of hazardous detection systems help ensure maximum prevention
Prevention
Toxic Chemicals
Creates jobs! Someone has to fight that fire?
Created a field in engineering devoted to prevention ( Fire Protection Engineering)
Economical Importance
More conscious of materials used in construction
The pollutants can turn neighborhoods into ghost towns
Helps us realize the environmental impacts at a first degree
Societal Importance
Histories largest tire fire (1990)
Burned for 17 days
CTS (Province) : 10 Million in damages
Burning tires are the most Toxic material
The Hagersville tire fire
By: Conal and Matt
What is it?
what does these pictures mean to you?

Health Impacts
Environmental Impacts
But....
- Since the industrial revolution, CO2 levels have increased by 25%

- Between 1850 and 1980 between 90 and 120 billion metric tons of CO2 have been released into the atmosphere by forest fires

- Burning of tropical forests contributes to 2.4 giga tons of carbon/year
What if its too late?
Severe industrial fires have involved multiple injuries, loss of life

- Smoke from fires can irritate eyes, airways and even cause chest pains

- Inhaling toxic chemicals released by fires can cause effects such as cancer, deformities, and ARS (acute radiation syndrome)
put the company at a financial loss
preventing revenue
possible law suits
employee injuries
Community damage
1917 - Halifax ship loaded with 9000 tons of high explosives (Halifax Explosion)

1979 - Partial nuclear meltdown in the US. 13 million curies of radioactive gas released

1986 - Nuclear power plant in Chernobyl (Ukraine) explodes. Fallout seen from Canada.

1988 - Military storage plant in Pakistan exploded killing 1,300


But why Tires?
Composed of rubber and petroleum
Releases oily sludge
Releases thick black smoke that attack the lungs
Releases sulfur dioxide into atmosphere
Chemical Formulas!
Thanks
Domestic Fires
Causes
Negligence (cooking, faulty heating etc.)
Children
Wiring
Christmas Decorations
Freak barbeque accidents
General Word Equation:
Toxic item+ Fire (O2) = Toxic air pollutants + CO2 + CO +C + H20

House fires
Fire produces flame, heat, oxygen depletion, smoke, and toxic gases
Toxic Air Pollutants
Acid rain
H2O(l) + SO2(g) ==> H2SO3(g)
When sulfur mixes with water in gasous form in the clouds
Damages trees, soil , buildings etc.
kills humans! ...(slowly)
We know what happens when we burn hydrocarbons but what about other materials ?
Chernobyl
Toxic- Poisonous substance
Well known nuclear power plant disaster that released radioactive particles into the atmosphere and made surrounding areas inhabitable
