Unit 1: Is there life off Earth?

Read and provide your opinion on this topic: Should tax dollars be spent to search for life on other planets?

Is There Life Off Earth?

Life as we define it on Earth is based on the following characteristics:

-Reproduction. Living systems are able to reproduce on their own.

-Growth. After a living system is “born,” it grows.

-Metabolism. Living systems share a complex chemistry that includes nutrient cycling (taking in food and giving off waste), energy production, protein synthesis, and DNA replication.

Macroscopic living systems such as animals and plants have so far not been found anywhere off our planet. But it is possible that there are systems off Earth that possess the cellularity, chemical organization, and complexity we equate with being “alive.” Traces of once-living microbes (fossils) have been found on Mars. Also, a meteorite found in Antarctica and thought to be from Mars contains some organic waste products and minerals very similar to those found where dead microorganisms on Earth have been collected. Finally, scientists have found microorganisms living in the Atacama Desert in Chile, which was once thought to be an inhospitable, sterile environment reminiscent of Mars. The microbes apparently are capable of long-term dormancy. When environmental conditions become favorable (rain once every decade), it is thought that these microbes then flourish.

Case Scenarios 
The Case Scenario assignments for this class will be found in Unit IV (Scenarios #1 and #2) and Unit VIII (Scenarios #3 and #4). Read the selected case scenarios below, and answer the questions that follow. Your answers should include information from your course materials and/or research when required, but, again, should be primarily in your own words. If you paraphrase or quote words or ideas from your course textbook or other resources, you should cite your sources using APA Guidelines. Your responses should be complete. Generally 200 to 300 words are required for a “complete” answer to a Case Scenario. 
You are required to submit both completed Case Scenarios as ONE document (Case Scenarios 1 & 2 in Unit IV as ONE document and Case Scenarios 3 & 4 in Unit VIII as ONE document) using the “View/Complete” link located in Unit IV and Unit VIII. Do not e-mail these assignments directly to your professor. By uploading through SafeAssign, your

university record will automatically be updated to indicate you have submitted your assignments and they will be provided to your professor for grading.  
Unit IV Mid-Term Case Scenario #1: 
The Situation: You are a Solid Waste Supervisor for your local municipality and it is 3:00 p.m. on a Friday afternoon prior to a much awaited four-day weekend. Temperatures have been running above normal for about 1-½ months now and the stress is beginning to show on your workforce, which is running at approximately 30% “no-show” rate. So, you have been filling in the workforce shortfalls by hiring day-labors from downtown, but still it is not enough. Your phone rings, one more time as it has done continuously since your arrival on the “early shift” this morning. You answer in your usual way, knowing that you are about to be blasted by yet another irate customer. As the customer on the other end of the phone starts in as you begin to take notes, shaking your head as you do so. The customer reports the following: “There is a 30 gallon garbage can sitting on the sidewalk in front of the customer’s business that has an extremely foul odor emanating from it. It has been there now for three days and it is beginning to smell quite ripe. This container, which is the customer’s office trash receptacle, contains last week’s standard office trash but also extensive human waste deposits left in the can from evidently numerous individuals of the local homeless population.” The customer is calling to complain that this morning during their regularly scheduled MSW pickup, your employees refused to take the contents of the can. 
The Questions: 
1. Did your employees conduct themselves properly by refusing to take the contents of the receptacle? 2. Are the contents of the receptacle classified as Solid Waste? 3. Are there any special handling considerations for this receptacle? 4. How do you respond to the customer and what do you do next?  
Unit IV Mid-Term Case Scenario #2: 
The Situation: You are the Safety Director for a medium sized municipality. Part of the municipality that you serve is an electric utility, complete with power transmission and distribution service to 265 square-mile electric grid. One day, one of your Safety Officers, who serves this electric utility, comes into your office with a substation construction foreman. They inform you that at a particular substation the utility has had to make some expansions to cover the growing needs of the community. To do so they have to erect a control house at the substation to contain all the necessary breakers and electrical components necessary to run the grid. The control house must remain stable and considering that the substation is built on top of a former city landfill that has been closed for the past 35 years; pilings need to be installed. Each piling is 3 feet in diameter and must go down into the ground 30 feet. They did not see the necessity of pulling a permit to do this work because, “hey, it’s all city property. Since they have been drilling, however, the substation construction foreman’s men have been complaining of the foul odors and are concerned now for their health. However, this concern does not seem to apply to one who is actively collecting and subsequently selling on E-Bay; what he considers to be antique bottles that are being pulled up as part of the drilling process. 
The Questions: 
1. Is it permissible to disturb the clay cap without a permit?  2. Are there health issues involved and if so what can be done to protect the employees that are working on site? 3. If there are no health issues involved, why not? 4. What steps would you take to deal with the antique bottle situation?  
Unit VIII Final Case Scenario #3: 
The Situation: The Case of the Oily Rags Outside of the City’s Fleet Operation Maintenance Bays there is a dumpster with a nicely painted sign saying Deposit Oily rags here. As the newly appointed EH&S Manager for the city you ask the next pressing question to the Maintenance Supervisor. “After you put your oily rags in the dumpster, where does the dumpster go?” His response was; “they take them out to the power plant and burn them.” You just smile and say “oh, that’s nice that the city has that capability” Two days later while you are out at the power plant, you ask the Operations Manager about the burning of oily rags in the unit. He tells you that they used to do that but now with the newer changes in place from the EPA they are not allowed to. So you ask yet again another obvious question; “then why are these dumpsters of oily rags coming out here?” He was surprised that you mentioned it because he had been wondering that himself. Now he has 4 dumpsters on his property filled with oily rags. 
BEM 3601, Waste Management 4 
The Questions: 
1. Should the oily rags stay on the plant site? 2. What responsibility does Fleet Operations have?  
Unit VIII Final Case Scenario #4: 
The Situation: It is Monday in the middle of August and you are a consultant for a local power plant. This particular plant is of an older design in which it can produce power by burning oil, coal, natural gas or garbage. To burn garbage the refuse trucks have to collect the waste and bring it to the plant. At the plant the garbage is dumped on what is known as the “tipping floor” and then hand sorted. Some items, such as mattresses, appliances and the more sturdy items cannot be burned so they have to be removed from the trash. Its already 98 degrees outside when you receive the phone call from the power plant. Apparently one of the sorters found something that you need to see. You hate going out there particularly on a Monday, because most of the time the garbage was dumped on Friday and has sat there all weekend getting “ripe”. When you arrive and open your car door, you realize you were right; it is very ripe! Gagging, you try to down-play your feelings and go to find the supervisor. This particular work group uses a “working supervisor” plan in which the supervisor also sorts garbage. You find him shortly after your arrival and as he is walking over to you, you noticed that he takes off his filthy gloves and lights up a cigarette. With his cigarette in his mouth he sticks out his hand to shake for introductions. All that is going through your mind is where have his hands been. He runs through his story and apparently one of the workers as found a box with a radiation sign on it, except the box is empty. 
The Questions: 1. What are your first actions? 2. What do you do if the radiation sign indicates a significant hazard?
