Unit III Homework Assignment

You have been tasked with identifying health hazards associated with a production line at a manufacturing facility.

Employees at the beginning of the line use a solvent to clean the surface of medium-size auto parts, and then they place the parts on a moving line. As the parts move along the line, an employee sprays them with a powder coating, and the parts

BOS 4301, Industrial Hygiene 2

move through an oven. Another employee removes the parts from the line and places them in slots in a cart for transporting to shipping.

You have been provided safety data sheets for the solvent used for cleaning the parts (click here to access) and the powder coating that is used (click here to access). Use the JHA form to identify the potential health hazards associated with the process. Click here to access the Basic Job Hazard Analysis form. You will use the Basic Hazard Analysis form to enter your responses and to answer the four questions listed below. Please upload this completed document to your instructor for grading.

Prepare a two-page homework assignment summarizing your health hazard analysis and answer these questions from the

Basic Job Hazard Analysis form.

1. What are the health hazards associated with the operation?

2. What are the primary exposure routes associated with each health hazard?

3. Are there any potential acute or chronic health effects for any of the health hazards you identified?

4. Are special hazards associated with any of the health hazards?

You may use the safety data sheets provided above, information from the OSHA or NIOSH websites, or academic references from the Internet to answer the questions. Citations are not required for this homework assignment; however you may want to use them in order to answer the questions.

Unit IV Case Study

You are asked to evaluate employees’ exposures to methyl n-amyl ketone during a painting operation. After careful consideration, you choose NIOSH Method 2553 for the sampling. You can access the method by clicking the link below:

National Institute for Occupational Safety and Health. (2003). Ketones II: Method 2553. In P. M. Eiler & M. E. Cassinelli (Eds.), NIOSH manual of analytical methods (4th ed.). Retrieved from http://www.cdc.gov/niosh/docs/2003-154/pdfs/2553.pdf

Your pre-sampling and post-sampling pump calibrations using a primary standard are both 0.05 L/min. You collect personal samples on two employees working in the operation. The samples are collected for 430 minutes (Sample 1) and 440 minutes (Sample 2).

1. Calculate the sample volumes for each of the samples.

The laboratory reports that the front section of Sample 1 contains 5,000 µg of methyl n-amyl ketone and the back section contains 200 µg of methyl n-amyl ketone. The front section of Sample 2 contains 4,000 µg of methyl n-amyl ketone and the back section contains 50 µg of methyl n-amyl ketone. Neither the front nor back sections of the field blank you supplied contain any detectable levels of methyl n-amyl ketone.

1. Calculate the concentrations of the two personal samples in µg/L and mg/m³.

2. Convert the result to ppm (MW for methyl n-amyl ketone = 114.2).

3. Show all the steps for your calculations.

You then reference OSHA’s Table Z-1 and find that the 8-hour TWA PEL for methyl n-amyl ketone is 100 ppm

1. Discuss how the results of the two personal samples you collected compare to the OSHA PEL, and describe the sampling method you implemented.

You also look up the ACGIH TLV for methyl n-amyl ketone and find that the TLV is 50 ppm as an 8-hour TWA exposure.

1. Discuss how the results for the two personal samples compare to the ACGIH TLV.

2. Discuss whether you would recommend comparing the results of your sampling to the OSHA PEL or the ACGIH TLV. Include your rationale for the choice, and explain how you would rationalize your choice to your employer.

The case study should be a minimum of three pages in length, and you should cite the NIOSH document using APA style.

Unit VIII Essay

Choose an operation for a workplace where you once worked or with which you are familiar where either chemical hazards or noise exposures were present. If you have never worked in a location where chemical hazards or noise are present, read about some examples on OSHA’s website and choose one that interests you. Complete the following tasks in a minimum two-page (500 word) essay:

1. Summarize the steps you would take to perform a hazard assessment of your chosen operation. Make sure you list the chemical hazards or noise hazards that are present using the example hazard assessment from OSHA’s website or one with which you are already familiar.

2. Discuss the use of personal protective equipment (PPE) for controlling occupational hazards in relation to the operation you chose.

3. Choose one hazard that you identified. The hazard can be a chemical or noise hazard. Summarize how you would evaluate employee exposures to the hazard. Include information about any sampling method you would use, how many samples you would collect, the types of samples you would collect (e.g., personal or area, TWA or short-term), and to which standards you would apply the results.

4. Assume there are several results indicating that employees are exposed to levels exceeding the applicable OSHA PEL. Using OSHA’s Hierarchy of Controls, summarize the control methods you would employ to reduce the risk for employees to an acceptable level. Your summary should include examples from each level of OSHA’s Hierarchy of Controls with a discussion of why you think the control would or would not be an effective method for reducing the exposure to an acceptable level.

5. Discuss how you would evaluate the effectiveness of the control methods you chose, both in the short-term and for the next 5 years.

Your essay must be in APA format, and include a minimum of two sources, at least one source being from the CSU Online Library.
