During the process of fighting fires there is alot to be aware of such as thick smoke. Smoke entering your lungs can be a huge risk when it comes to your cardiovascular health. However each firefighter is given a face mask to help you to breathe and protect your lungs from the smoke. How protective are these masks? Alot of the masks contain center ventilation orifice allowing easy air exchange and helps prevent buildup of CO2(the thick smoke created by fire).
Is it possible to use the Table of Placards in the ERG to find the correct Guide for this incident? YES IT IS POSSIBLE BECAUSE THE I.D NUMBER ON THE PLACARD WILL LEAD TO THE GUIDE NUMBER. What is the primary hazard of material covered by this Guide? WILL ACCELERATE BURNING WHEN INVOLVED IN FIRE.SOME MAY DECOMPOSE EXPLOSIVELY WHEN HEATED OR INVOLVED IN A FIRE.MAY EXPLODE FROM HEAT OR CONTAMINATION.SOME WILL REACT EXPLOSIVELY WITH HYDROCARBONS (FUEL).MAY IGNITE COMBUSTIBLES (WOOD,PAPER,OIL,CLOTHING,ETC. ).CONTAINERS
A fire, can cause sudden panic as it is an unpredictable event. There are certain priorities that should be followed in the case of a fire. The first and most important thing to do would be to inform all service users, medical professionals, staff, visitors and any other persons inside the building that there is a fire. This would be done with the use of a fire alarm, as soon as an individual notices the fire or the signs of a possible fire they should trigger the alarm, in order to alert and inform everyone else of the danger. This would be followed by the second most important priority which would be evacuating all persons from the building.
Now the other threat was the polyurethane foam they used to insulate the walls and ceiling. Now this is highly flammable and once this caught on fire it quickly spread throughout the whole building and made it as bad as it was. If they were to of used a less flammable insulation then this fire probably would not have claimed so many lives. Now there were a couple different
“Our Gas Guzzlers, Their Lives” by: Nicholas Kristof In Nicholas Kristof’s article “Our Gas Guzzlers, Their Lives”, many valid points are given to justify and provide more information on how the amount of gasoline used and green house emissions are negatively affecting other parts of the world. In many ways this article shows how there is a need to curb green house gas emissions before the damages being made are worsen. Not only has Kristof’s article triggered emotional responses as he explains the harsh realities that the “westerners” are causing, he is also able to further expand on this topic by providing valid and appropriate data. Well many would argue that it is hard to slow down or eliminate our gas and green house gas usage; Kristof provides many valid points that give good and humane reasons to at least try to reduce out usage. “Our Gas Guzzlers, Their Lives” by Nicholas Kristof shows the readers how our actions and usage of gas and out green house gas emissions are not only damaged to the environment but to people around the world.
When the fuels combust, oxygen and fuels react, and heat released. The water then absorbed the heat from the combustion. In this experiment the calorimeter of energy is used to measure the temperature of the heat that is released from the cashew. The equation to find the energy produce during
“While [hydraulic fracturing] can help provide energy for America's future, it also poses a new dangerous threat to wildlife and the environment. Toxic chemicals are used during fracking that can infiltrate and contaminate habitat, waterways, and even the drinking water that people and wildlife depend on” (1996-2013). Evidently, “some opponents of oil and natural gas production claim that fracking has serious environmental consequences. The truth is, while all development has challenges, hydraulic fracturing technology has a strong environmental track record and is employed under close supervision by state, local and federal regulators. Studies by the Environmental Protection Agency (EPA) and the Ground Water Protection Council (GWPC) have confirmed no direct link between hydraulic fracturing operations and groundwater contamination.
Fireworks are known to be dangerous and have a potential of causing serious injuries. Therefore, the potential liability of I juries caused to customers by fireworks is unavoidable. Upon exploding, fireworks can send out very hot embers. Furthermore, if positioned wrongly, a firework can set a house on fire. However, not all these injuries are caused by ignorance, carelessness or negligence.
Extrinsic factors include airway infection and increased air pollution and intrinsic factors such as increased oxidative stress and altered immunity (Tsoumakidou & Siafakas, 2006), although the exact mechanisms are not known (Bathoorn et al, 2008). Ball (1995) states that infections play a major role in the aetiology of acute exacerbations. It is known that patients with COPD have significant impairment of the lung defence mechanisms and colonisation of the bronchial system seems to be an important consequence of the disease, particularly in exacerbations according to Erkan et al (2008). Discussion The prevalence of COPD appears to increase with age according to Devereux (2006) and Soriano (2000). However, it is interesting that they attribute this increase solely to aetiological factors rather than the normal process of ageing.
Some aspects of climate change may already be irreversible. Yet many scientists believe that by taking positive action now, it is possible to slow the pace of climate change and reduce further global warming. Changing our lifestyle and our behaviour will help reduce the human impact on the environment. Driving a car, using electricity to light and heat your home, and throwing away garbage all lead to greenhouse gas emissions. You can reduce emissions through simple actions like changing a light bulb, powering down electronics, using less water, and recycling.
