Why Is Dry Ice Dangerous

Dry ice, which is the solid form of carbon dioxide, is not dangerous if it is stored and used correctly. It can present hazards because it is extremely cold and quickly sublimates into carbon dioxide gas. While carbon dioxide is not toxic, it can build pressure or displace normal air, potentially causing problems. Heres a closer look at the dangers of dry ice and how to avoid them, whether you buy or make dry ice. Dry Ice Frostbite Dry ice is extremely cold! Skin contact kills the cells, giving you a dry ice burn. It only takes a couple of seconds to get burned, so its best to use tongs or gloves when handling dry ice. Dont eat dry ice. If you use it to cool a drink, be careful that you dont accidentally get a piece of dry ice in your mouth or accidentally swallow some. Asphyxiation Dry ice forms carbon dioxide gas. Although the carbon dioxide isnt toxic, it changes the chemistry of the air so that there is a lower percentage of oxygen. This is not an issue in a well-ventilated area, but it can cause problems in enclosed spaces. Also, the cool carbon dioxide gas sinks to the floor of a room. The increased concentration of carbon dioxide is more likely to cause problems for pets or children than for adults, both because they have a higher metabolism and because they may be closer to the floor where the concentration of carbon dioxide is highest. Explosion Hazard Dry ice is not flammable or explosive, but it exerts pressure as it changes from solid dry ice to gaseous carbon dioxide. If dry ice is placed in a sealed container, there is a risk of the container rupturing or of the cap rifling off of the container when you open it. A dry ice bomb produces extremely loud noise and shoots out pieces of the container and dry ice. You could harm your hearing and become injured by the container. Pieces of dry ice could become embedded in your skin, giving you internal frostbite. To avoid these dangers, dont seal dry ice in a bottle, jar or locking cooler. Its fine in a paper bag in your refrigerator or freezer or in a cooler without a tight seal.

Andre Gide And His Pure Novel - 2098 Words

Hanjie Ye Sally Franson WRIT 1301 22 April 2015 Andre Gide And His Pure Novel Andre Gide, one of the greatest writers of twentieth century France, has lived a life full of contradictions — he was raised in a protestant family but he endeavored his whole life to extricate himself from the religious restriction; he married his cousin Madeleine but their marriage existed in name only; he claimed he loved Madeleine with his full heart but he identified himself as gay; he was known as a successful novelist by his semi-autographic novel series, The Immoralist, Strait Is The Gait and The Pastoral Symphony, but he referred to these works only as tales; he considered The Counterfeiters his first novel but this work was categorized as an anti-novel by Jean-Paul Satre. The origin of Gide’s contradictions, as Gide said himself, is â€Å"a conflict between the rules of morality and the rules of sincerity†(Journals I 19). On the one hand, Gide was deeply influenced by the protestant morality; on the other hand, his gay identity kept pushing himself to be sincere to his inner self. Torn by such a conflict in his whole life, literary creation became Gide’s own way to survive. â€Å"QUOTE†(If It Dies xx) Among all of Gide’s literature experiments to solve the conflict, pure novel is the most important idea he has proposed. This essay will discuss the concept of Gide’s pure novel and his approach to this concept in The Counterfeiters.

Matthew Nestasia Essays (386 words) - Video Surveillance

Matthew Nestasia Body cameras Good or Bad? Should the police feel like their privacy is being violated? The answer is yes, with most officers of the law now being required to wear cameras on their uniforms while on duty they are unable to have any form of privacy with their partners. Even though I do not like the lack of privacy cops have now, I still feel like the body cam is a great tool for evidence that could defend or worsen an officer's case. The advantage to wearing the camera is that it records everything that is happening to the cop, so if they're in the middle of a crime scene face to face with the criminal the camera will record the actions and words of the suspect. This evidence can be used to almost certainly incarcerate the criminal for their actions. For example the video we had watched during class, on video the criminal was caught driving recklessly and attempting to assault the officer who gave chase. If the criminal had survived the encounter he would have been thrown in prison thanks to the v ideo evidence. The body camera is also good for weeding out the dirty cops in the force. Since the officers wear the camera while on patrol often times they'll forget to shut it off when doing things in private. You'll either find an officer in the bathroom or the officer doing some shady business with a criminal suspect. While this invasion of privacy has some good benefits, it also has bad ones too. Imagine your with your partner in the car and the two of you are just hanging out and talking, you have to watch what you say the entire conversation because your being recorded. The possibility of you saying something dumb like "The chief is a loser" is very high when you think you're alone or with your friend, this could lead to some possible tension among officers that could lead to someone losing their job. In conclusion I feel that body cameras are necessary and should be worn by all officers while on duty. But I don't ignore the issues surrounding the body cam aswell , like a lack of privacy. I almost think of them as a necessary evil in a way.
