Occupational Safety - Assignment Example The biggest problem here is that the diseases do not develop immediately but appear after a few years of exposure. The impact of pollution at workplace on productivity has been well investigated. Studies on the impact of pollution at work environment in productivity reveal a tendency of reduction in the economic activity (Marrewijk, 2005). "Sick building Syndrome" (SBS) and 'Building related illness' (BRI) gives rise to employee complaints such as headaches, dizziness, disorientation, fatigue, ear, eye and throat irritations. The world demand for high-speed ferries and LNG tanks is being met with an increase in Aluminium welding and casting production. This has introduced a new health hazard to the Aluminium welders and ways are being probed to protect the welders against the Aluminium fumes. In the U.K, the Control of Substances Hazardous to Health (COSHH) regulations stipulates that the occupational expose limit for Aluminium fume should not exceed 5mgm exp 3 of air. Aluminium fumes during welding also generate quantities of ozone gas, which can cause nausea (Rabin, 1997) and unconsciousness. Welding is a process in which metal or other thermoplastic materials are joined together by the application of heat or pore sure or both. Electric welding was introduced in 1940s. Aluminium welding has been in prominence since 1970. There are several types of welding like Arc welding and Manual metal arc is a common process where the workers are exposed to the fumes. Carbon arc, Cold welding, Electron beam welding, Flux core arc welding, Gas welding, Gas metal arc welding, Gas tungsten arc welding, Shielded metal arc welding, Plasma arc welding, Laser beam welding are the other welding processes where workers are exposed to metal fumes. The welding workers have a high exposure of metal fumes and the exposure depends on place, confined space, workshop or open air. The metal fumes depend on not only the Aluminium but also the process involved, which may produce gases like acetylene, carbon monoxide, oxides of nitrogen, ozone, phosgene and tungsten. The metal fumes primarily enter the human system by inhalation route namely Respiration.. The deposition of these inhaled metallic particles is influenced by its physical and chemical properties and a variety of host factors. In the lungs, these particles produce a variety of reactions depending on the concentration, duration of the exposure of the particles, and degree of exposure. All Metallic particles greater than 10 are deposited on the Mucous membrane in the nose and pharynx. Particles between 3m and 10 m are deposited throughout the trachea of the lungs. Particles less than 3m are deposited in the alveoli and cause serious hazards. These particles have a fair chance of being carried into the blood stream and cause Hepatotoxicity

Opportunity to Get Higher Education - Essay Example Alongside each  paper  I did, the lecturer commented on my strengths and weakness. Further, the  lecturer  gave me suggestions on how I can improve weaker areas. I do not  often  read  textbooks, probably; this was the least helpful thing I had through this class. A textbook is a tool and no need of reading all that is in there some  irrelevant  to the subject. The reading assignments we worked on were extremely specific and always applied directly to the assignments. The assignments I enjoyed most were those I had  total  discretion in terms of my topic of choice. Persuasive research  paper  and also the  letter  to the  writer  were my  best  assignments I did in this class, and I scored  best  in these two papers. In my letter to the editor, I discussed animal egret and abandonment and came up with a solution. The  solution  called â€Å"get  tough† which included  multiple  steps. The real key  solution  was using  the community  for outreach and  involvements  in ensuring animal rights  have adhered. The issue of animal rights is particularly  salient  to me because I work in an animal shelter,  and  was ease  getting  all the  information I required. The story about basset hound  found  in  shock  brought in  passion  for this. I looked in depth on the importance of spaying or neutering your pets in my persuasive  paper. This issue  was deeply connected  to this  letter  am writing to the editor. Animal abuse and neglect would be substantially lessened.  This  would be so if there were not so many unwanted puppies and kittens born to people who cannot protect  them and not be wishing to do so.  I opened up the paper with a series of questions, which I think helped  catch  the readers attention and I had a  sizeable  number  of facts such as the current stats--local and  a nation--regarding unwanted pets and annual pet birth rates.
