  Overview of the Projects in each unitIn this course, you are asked to prepare a Comprehensive Report as the Final Project, which is made up of various scenarios throughout each unit. Each unit (i.e., units II through VIII) contains a scenario for you to solve and to provide recommendations. By the end of the course, you are asked to collect all of the individual responses from each scenario and to insert them into a Comprehensive Report as the Final Project.The theme or setting for each projectYou are employed by Be Safe Consulting, Inc. (BSCI), as an entry level safety consultant. You report directly to Bob Sanders, the supervising Certified Safety Professional (CSP). For the last two months you have been assigned to conduct a comprehensive safety evaluation for Acme Manufacturing Co. Based on the observations, calculations, and recommendations in Unit II through Unit VIII prepare a Comprehensive Report to Bob Sanders, who will, in turn, use this information to prepare a final report to Acme Manufacturing Co. Board of Directors. While the Board of Directors may be looking for detailed business impacts, Bob Sanders is looking for a detail of potential employee hazard exposures and your recommendation rationale (calculations, observations, and/or regulation).Ventilation ReportYou are employed by Be Safe Consulting, Inc. (BSCI) as an entry level safety consultant. You report directly to Bob Sanders, the supervising Certified Safety Professional (CSP). BSCI has been contracted by Acme Manufacturing Co. to conduct a study to determine employee exposures to various particulates and gases. In addition, your company has been contracted to determine if the current ventilation systems that are in place are adequate to protect employees from an over exposure to these chemicals. After conducting a field assessment, prepare a written report that Bob Sanders can utilize to prepare a final comprehensive report for the Board of Directors. During your field investigation, you find the following field observations:Welding RoomThe company has six welding booths, or areas that are partitioned only for the use of welding curtains. The booth is open to mixing in the front and top. The company is worried about the welder’s exposure to iron oxide (PEL 10 mg/m³). For a valid sample, you must have a minimum of six hours of sampling (The remaining two hours of the work day is considered to be equal to or less than the sampled exposure. As a result of your air sampling over an eight-hour time period (i.e., the work schedule), you receive the following analytical report:

  Name	Location	Conc. 1	Time 1	Conc. 2	Time 2	Conc. 3	Time 3
  Anne Welding	Booth #1	4.3 mg/m³	150 min.	3.7 mg/m³	150 min	2.2 mg/m³	240 min
  Frank Worldly	Booth #2	2.1 mg/m³	180 min	2.8 mg/m³	120 min	3.1 mg/m³	240 min
  Jim Young	Booth #3	1.7 mg/m³	205 min	1.25 mg/m³	125 min	1.03 mg/m³	150 min
  Betty Johnson	Booth #4	12.8 mg/m³	165 min	11.2 mg/m³	72 min	9.8 mg/m³	123 min
  Jack Jones	Booth #5	7.8 mg/m³	190 min	14.2 mg/m³	149 min	8.8 mg/m³	140 min
  Joey Apperton	Booth #6	3.9 mg/m³	155 min	4.6 mg/m³	90 min	2.1 mg/m³	46 min

  Based on this information, determine the employee’s actual exposure to iron oxide, whether the samples were valid, and if not, why? Show your work either in the report or as an appendix.During further evaluations of the welding booths, you determine that each booth utilizes a local exhaust system to remove the iron oxide and other contaminants prior to mixing with the breathing air. You take the following measurements:

  Location	Air Velocity (fpm)	Work distance from exhaust opening (in inches)	Duct Diameter (in inches)	Flow Rate (cfm)
  Booth #1	683	18	8	Unknown
  Booth #2	Unknown	16	8	12,375
  Booth #3	710	16	12	Unknown
  Booth #4	184	26	8	Unknown
  Booth #5	Unknown	22	8	9721
  Booth #6	Unknown	18	12	11421

  After taking the air samples for employee exposures to iron oxide, then measuring and calculating the performance of the local exhaust ventilation (paying particular attention to the specifics), what recommendations would you make to reduce the employee’s overexposure, if any, to the ventilation systems?Hazardous Materials Storage AreaAs part of your assessment, you have been asked to evaluate and determine if the hazardous materials storage area has adequate ventilation. In addition to the federal requirements, Acme’s insurance carrier requires that they have a minimum of 12 air changes per hour. In your evaluation, you collect the following information:

  Area Width (ft.)	Area Length (ft.)	Area Height (ft.)	Ventilation Supply #1 (volume-cfm)	Ventilation Supply #2 (volume-cfm)
  22	30	14	874	993

  Determine if the current hazardous materials storage area is adequate and meets the requirements of Acme’s insurance carrier. What recommendations would you make to correct the discrepancies, if any?Foundry RoomAcme has a foundry room, which is nearing the point of being outdated in terms of engineering controls. For example, one employee stands near an operation that has a canopy hood exhaust and routinely puts his face in the flow of the hood, causing him to inhale particulates and gases that are directly being drawn into the hood. Part of your evaluation is to make a recommendation for a new type of exhaust system. Which one would you recommend, and why?Respond to the details in each section, and format your report in APA style. Include at least each of the following 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-Measurements and calculations (show your work).
  • At least one page (double-spaced) in length (not including the reference appendices).

  Prepare your report in a word-processing application (i.e., Word) using APA formatting for all references and in-text citations

Radiation Safety Report

The executives at Acme Manufacturing Co. were impressed by your first report, and they have asked you and BSCI to return for more work. BSCI has been contracted by Acme Manufacturing Co. to conduct a study to determine employee exposures to radiation. In addition, your company has been contracted to determine the effectiveness of engineering controls, including shielding. 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:

Test Equipment and Repair Facility

The company has an on-site test equipment and repair facility. Much of the test equipment contains a radiation source. Normal practice inside the facility is to limit the time of exposure of employees working on this equipment as a method of control. However, the company is looking at the possibility of installing lead shields or increasing the distance from the source, thus increasing employee time working on equipment. Based on the following information determine the employee’s exposure:

Based on this information, determine the employee’s actual exposure rate to the radiation source. Show your work (either in the report or as an appendix).

The second option under consideration is to install lead shields in order to reduce the employee’s dose rate. Using the information provided in the table above, determine the intensity at the same distances listed above if a 5 cm lead shield was placed between the source and the detector. [µ for lead, (662 keV gamma ray) = 1.23 cm-¹]

Radar Testing Facility

As part of your assessment, you have been asked to evaluate the estimated power density levels for both near and far fields. When there is no gain listed in the problem, always defer to a gain of 10. Recall that 1 watt = 1,000,000 µW(microwatts). You have conducted your assessment and measurements with the following data:

Laser Laboratory

Acme Manufacturing is currently considering constructing a laser laboratory, which will contain Class III, IIIA, and IIIB lasers. Identify the safety control measures that the client must consider before proceeding to the design phase of the project.

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, exhibiting training and management techniques. 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)

Carpentry Shop #2

Inside Carpentry Shop #2, there are six machines operating almost continuously, including table saws, planers, exhaust systems, jointers, with 10 employees working in this area. To determine whether this table should be designated as a hazardous noise environment, thus requiring employees to be entered into the hearing conservation program, you must calculate combined exposures and treat the entire area as one noise source. The following table indicates the recorded measurements that you collected during your on-site assessment. Does the data from this table indicate a hazardous noise environment, and do you recommend entering employees into a hearing conservation program?

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/m², but the Project Engineer is requesting the information in W/m². Given the following data, convert N/m² to W/m² and include it in your report:
