Pneumoconiosis


Pneumoconiosis is also known as Black lung. Pneumoconiosis can develop when airborne dusts, are inhaled at work. Exposure to silica, asbestos, and coal dust are the most common causes of pneumoconiosis. Most dust types are not known to cause pneumoconiosis. 

In 1969 and 1977, regulations for U.S. underground coal mines were mandated by federal legislation and amended. However, in 2005 and 2006, clusters of rapidly progressing and potentially disabling pneumoconiosis were reported in certain geographic areas. CDC’s National Institute for Occupational Safety and Health (NIOSH) responded to the reports by instituting field surveys that were conducted under the Enhanced Coal Workers’ Health Surveillance Program (ECWHSP). The results showed a total of 37 cases of advanced pneumoconiosis. 

The national chest radiograph program recommends that all miners receive an initial radiograph upon hire, a second radiograph after 3 years, and additional radiographs at 5-year intervals for the remainder of their careers. The medical record data indicated that all 37 miners had worked underground for at least one interval of > 10 years without a chest radiograph.  

Due to this incident The Mine and Safety Health Administration has begun a national education and training campaign to increase awareness and enhance prevention of pneumoconiosis. In addition, NIOSH is examining minging environments to evaluate current exposures and improve guidance on dust control, and field investigations are being used to inform ongoing activities aimed at preventing pneumoconiosis among coal miners.

    Its important to provide training and increase the awareness to prevent pneumoconiosis. Periodically screening is great idea to follow up the health condition of the workers and also its best element that can be used for early diagnosis of pneumoconiosis in order to have early intervention and eliminate complications.

1) Consider your workplace or a workplace of one of your family members. Are there chemical, biological, radiological or ergonomic issues? Using the industrial hygiene hierarchy of controls, how might you address the issues? How are they being addressed in reality? The issues that my workplace typically experience are biological and ergonomic issues. Working with children brings different blood and bodily fluid exposures. Teachers and students are exposed to viruses. Depending on the age group, teachers are also lifting children throughout the day. Using the hierarchy of controls, I would address these issues with administrative controls and personal protective equipment. To reduce teachers from straining and hurting themselves while lifting children and moving furniture we should go through training to know the proper ways to push, pull, and lift objects on the job. One way to avoid getting or spreading viruses is through keeping everyone's hands clean as well as the objects...

After reading  Lead Poisoning  by Herbert Needleman and the NigeriaCasey article, I now know more of the effects of lead poisoning. Before reading about the history I had no idea that they used it for wine to sweeten it. I am happy to see how the understanding of lead toxicity have advanced throughout the years. The more we know the safer our families are. It is interesting to see how a toxic like lead can lead to behavior problems. It is very unfortunate that children suffer the most.  I am glad that they were able to catch it in Nigeria. My husband is from Nigeria and seeing how the village life is, I am surprised that they caught it and cared to do something about it. Many children lost their lives because of this exposure. People in villages are poor and lack many resources. Fortunately some of them have families in America that do help financially. We have come a long way but still have a long way to go.

M11.5 Zero Waste Life

After taking this course and learning about how our lifestyle choices effect the environment and the world we live in, I started to make some gradual changes in my home like: Period Cups No Plastic Water Bottles or Paper Plates Filtered Water Stainless Steel Bottles The first change actually happened last year before I started this course. I was not intentionally trying to help the environment I just wanted to save money. It is very unfortunate that women have to pay for feminine hygiene products every single month because of a biological process that is out of our control. I came across a couple of YouTube videos where women talked about period cups. This was something that I had never heard of before so I did a little more research and decided to go ahead and try it. I had nothing to lose. That was the best decision that I have ever made! I purchased the divacup and have not purchased a single tampon or pad and it has been a year and half.  The next choice that I ...
