Chemistry of hazardous materials - Essay Example The sooner the explosive is named, the quicker a response team can put together a plan of action. Explosives are classified by DOT (2012): Explosives must have a driver that is physically and mentally fit to understand all local, state, and federal laws regulating explosive transport. The Department of Labor (2012) explains that no smoking or weapons can be carried on their transport. Metal should be covered so no spark occurs. These transports should not be left alone. Like other hazardous materials, explosive transports shall be clearly marked as such. Finally, the Department of Labor (2012) requires a working fire extinguisher that drivers are trained to use in the transports. Explosives are different from other hazardous materials due to the mass destruction caused. For example, an explosion can destroy a road, railway, or ship and everything in the vicinity. A toxic gas leak can lead to evacuations, but can be cleaned up with little or no life loss. The property damage is less as well. Once something explodes it cannot be taken back. It damages, kills, and can potentially lead to other explosions. These are a few reasons explosions are different from other hazardous

How has technology influenced commercial aircraft to make them more Research Paper - 1

How has technology influenced commercial aircraft to make them more eco-friendly and safer - Research Paper Example The transport sector is one of them. Over the recent years, manufacturers of various brands of vehicles, trucks and aircrafts have come up with designs that have increased fuel efficiencies. The result of this has been reduced green house gas (GHG) emissions from the sector. In aviation specifically, a four-pillar strategy has been identified as a mitigation measure to GHG emissions from the sector. The four pillars are efficient infrastructure, effective operations, improved technology and positive economic measures (Centro 98). Of the four, technology has proved to be the most important prospect in minimizing aviation emissions. Since its introduction in the early 1900, commercial aircraft has been developing due to technological advances and recent transformations have made commercial airliners more eco-friendly and safer. This paper explores the ways in which has technology influenced commercial aircraft to make them more eco-friendly and safer. The paper begins by outlining technological advancements that have been made on commercial aircraft and how they have increased its environmental friendliness and safety. This is followed by a brief description of the savings made from these advancements and possible future advancements that can be made to make commercial aircraft more eco-friendly and safer than they are today. Commercial aircraft are second to highway vehicles in terms of motor fuel consumption. At the same time, the demand for air travel in the world is growing by almost twice the rate of growth experienced by highway vehicles. This has presented opportunities for airliners to expand their air routes, number of flights and even their fleet. All these have the potential of increasing the environmental hazards presented by commercial aircrafts on the environment. However, the industry has enjoyed many technological advancements to accommodate the increasing traffic while mitigating this. Greene (538) states that since the early 1970s,
