Hazardous Noises Report
After receiving good remarks from your previous work, you hear that Acme Manufacturing Co. has asked you and BSCI to return for some additional work. BSCI has been contracted by Acme Manufacturing Co. to conduct a study to determine employee exposures to noise. In addition, Acme Manufacturing Co. has requested that while on site, you conduct a needs analysis to determine the development of a new safety training program. Explain your methodology and the steps in conducting this needs analysis . After conducting a field assessment, prepare a written report for Bob Sanders (CSP) to present to the Board of Directors. During your field investigation, you find the following field observations:
Machine Shop #1
The company has an on-site maintenance and repair facility. Inside Machine Shop #1, there are five employees that operate a variety of machines, ranging from stationary and portable grinders, drill presses, and metal shearers. Based on the information provided in the following table, determine the individual employee’s exposure: (DO NOT COMBINE NOISE LEVELS) Location

Electronic Communication Repair Shop
Acme Manufacturing is currently considering remodeling this shop in order to install a new noise absorbing wall and floor insulation. They have asked that you review the previous history of noise level exposures in this area and provide your recommendations. However, this data is given in measurements of N/m 2 , but the Project Engineer is requesting the information in W/m 2 . Given the following data, convert N/m 2 to W/m 2 and include it in your report:

Your report should be in APA style and be at least one page in length, double-spaced (not including title, references, and appendix pages). Respond to the details in each section and be sure to include at least each of the following sections in your report for this unit:
Introduction: Briefly describe why the studies were performed (why you started the study).
Report details: Briefly discuss the details of the scenario (what you found from the study).
Conclusions and recommendations: Briefly describe your recommendations based on your findings (what you recommend to resolve any deficiencies) .
Appendix: Provide measurements and calculations (show your work).
Thermal Stressors Report
Bob Sanders (your supervisor) has another job for you. Acme Manufacturing Co. was impressed by your last report, and they have asked you to return to complete another job. BSCI has been contracted by Acme Manufacturing Co. to conduct a study at one of its facilities to determine employee exposures to various thermal stressors at different times. You are to conduct this study in January and July of 2012. After collecting and recording data from the field assessments, prepare a written report for Bob Sanders (CSP) to present to the Board of Directors. During your field investigations, you find the following field observations:
Security Personnel
The security personnel, while contracted by Acme, are still employees that need to be monitored. There are three main entries that are staffed with security personnel. These entries have a booth, which is roughly 5’x5’ with no heating or cooling. Each security officer works an eight hour shift, with two separate fifteen minute breaks (one during the first half of the shift, and the second during the second half of the shift) and one 30-minute meal break. The only opportunity to rehydrate is made during the break or meal periods. There are no drinking fountains or coolers in the security booths. Calculate the wind chill factor and wet bulb globe temperature (WBGT) for each location.

Hydrostatics and Hydraulics Report
BSCI has another job for you at Acme Manufacturing Co., and Bob Sanders (your supervisor) has asked you to complete it. BSCI has been contracted by Acme Manufacturing Co. to collect measurements of various industrial storage facilities and certain aspects of its fire suppression system. After collecting field measurements and calculating values, prepare a written report for Bob Sanders (CSP) to present to the Board of Directors. During your field investigations, you find the following field observations:
Piping System Repair
A piping system repair must be made to a vertical piping system. The pipe is 60 ft. long prior to its turn to a horizontal direction. There is a repair that must be done at 35 feet above the floor. The pipe is filled with a liquid having the same properties as water. Due to operational considerations, the pipe cannot be drained. The fluid is considered non-hazardous due to its chemical properties. Before the repair can be completed, a decision has to be made about the material to use and the method in which the repair can occur safely. At the location of the pipe repair, what is the pressure of the fluid? (NOTE: the height of the cylinder is the length of the pipe minus the height of the repair from the floor.)
Water Storage Tank
Some repairs have been made to the existing water storage tank. New valves and piping systems are to be installed in the distribution system. You have been asked to calculate the velocity of the fluid through the bottom drain opening and prior to entry into the distribution system. This velocity will help to determine the specific valve that must be installed prior to the distribution system. The tank at its highest point is 24 feet. Determine the velocity of the fluid at fluid heights of 24 feet, 18 feet, 12 feet, and 6 feet.
Fire Suppression System
In a horizontally installed piping system, water flows through a 10 inch pipe. The head loss in a 500 foot section is 40 feet. The residual pressure at Point A is 55 psi and the velocity at Point A is 7 ft./s. If the velocity at Point B is 8.5 ft/s, what is the residual pressure at Point B ?

Fire Prevention and Protection Report
Acme Manufacturing Co. has another job for BSCI, and Bob Sanders (your supervisor) asks you to complete it. BSCI has been contracted by Acme Manufacturing Co. to conduct a fire protection and prevention inspection. During the inspection, you make several notes, which you use to prepare a written report. Later, Bob Sanders (CSP) intends to utilize your report as he presents the details to the Board of Directors. During your field investigations, you find the following data:
Welding Shop
In the welding shop, you collect measurements of the floor space which measures 125 ft. x 80 ft. In the center of the room, near a column, you notice that there is one fire extinguisher, which is a 2A10B:C rated extinguisher. Determine if this is an adequate number of extinguishers for this area. Explain.
Molding Shop
In the molding shop, employees prepare resins to shape the molds used in creating one of the products manufactured by Acme. The area has a strong odor of acetone, which is used significantly in the preparation of the resin molds. In this area, you notice that there is a sprinkler system, and the sprinkler head is green. What is the maximum ceiling temperature for this area?
As mentioned, employees in this shop use a significant amount of acetone in the preparation process. Also while conducting the inspection of this shop, you notice an overhead gas space heater with an open flame. What are the UEL/UFL and LEL/LFL of acetone? What actions would you take immediately in this area? Explain.
