San Francisco, US

For the following research paper assignment, you have been asked to perform an evaluation of employee exposures at a small automobile parts manufacturing facility. The manufacturing processes include two metal presses, two machining stations, three welding stations, a small paint booth, and a shipping/receiving area. There are two employees working at each press, one person working at each machining station, one person working at each welding station, two people working in the paint booth, and four employees working in the shipping/receiving area. One of the presses is a 2,000-ton press, and the other press is a 200-ton press. The 2,000-ton press is the greatest noise source for the facility. The machining area uses a metal working fluid. The safety data sheet (SDS) for the metal working fluid is attached here. All welding is performed on stainless steel. The painting booth uses a powder coating operation, but the employees use xylene and methyl ethyl ketone (MEK) to clean the parts prior to the powder coating operation. At the end of the shift, one of the employees uses 1,3 butadiene to clean the nozzles for the paint booth. The facility uses two electric forklifts to move materials between the production area and the storage warehouse and between the warehouse and the shipping area. All employees work an 8-hour shift. Part 1: Using the information on anticipation and control we studied in the textbook, identify the hazards that are present in the facility. In your discussion, explain why you chose the hazards, and describe whether you believe the hazards to be actual hazards or potential hazards (which require further evaluation). Describe the specific location(s) at the facility where the hazards are located, and determine how many employees are potentially at risk in those areas. Your response for Part 1 should be at least one page in length. Part 2: Using the information on evaluation that we studied in the textbook, summarize how you would measure the personal exposures to the hazards that you identified in Part 1. Use the Occupational Safety and Health Administration (OSHA) website (https://www.osha.gov/dts/sltc/methods/toc.html) or the National Institute for Occupational Safety and Health (NIOSH) website (http://www.cdc.gov/niosh/docs/2003-154/default.html) to select the specific sampling and analytical method that would work best to evaluate any chemical hazards you identified. Provide a summary of the sampling media you would use, include the sampling flow rate, discuss how long you would sample, and explain how you would calibrate the sampling train. Include a discussion about why you selected the specific sampling and analytical method. Your response to Part 2 should be at least one page in length. Part 3: Access the attached sampling results here. For each set of results, perform the following actions: Calculate the 8-hour time weighted average (TWA) exposure. Compare the results to the appropriate OSHA permissible exposure limit (PEL). Determine which results exceed an established OSHA PEL. Write a one-page summary of the sampling results; document the exposures that exceeded an OSHA PEL, and identify those areas that you believe will require the application of controls to reduce risk. Include your calculations, include a list of the OSHA PELs you compared the results to, and explain how you decided that an exposure exceeded an OSHA PEL. Part 4: Using OSHA’s hierarchy of controls, recommend the control methods that you believe would be the most effective for reducing the risks associated with the exposures that exceeded the OSHA PEL above. Explain how you would implement the controls and how you would evaluate the effectiveness of the controls. Also, discuss any interim control methods you would recommend for the facility. This section should be at least one page in length. Include a reference page and in-text citations for all sources you used in this project, including your textbook, using proper APA format.

Symptoms of respiratory irritation may include coughing and difficulty breathing. Not classified Not Applicable Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames. This material will burn although it is not easily ignited. See Section 7 for proper handling and storage. For fires involving this material, do not enter any enclosed or confined fire space without proper protective equipment, including self-contained breathing apparatus. Highly dependent on combustion conditions. A complex mixture of airborne solids, liquids, and gases including carbon monoxide, carbon dioxide, and unidentified organic compounds will be evolved when this material undergoes combustion. Combustion may form oxides of: Sulfur. Eliminate all sources of ignition in vicinity of spilled material. Stop the source of the release if you can do it without risk. Contain release to prevent further contamination of soil, surface water or groundwater. Clean up spill as soon as possible, observing 12 APRIL 20, 2015 2 of 8 7721 precautions in Exposure Controls/Personal Protection. Use appropriate techniques such as applying non-combustible absorbent materials or pumping. Where feasible and appropriate, remove contaminated soil. Place contaminated materials in disposable containers and dispose of in a manner consistent with applicable regulations. Report spills to local authorities and/or the U.S. Coast Guard’s National Response Center at (800) 555-8802 as appropriate or required. Avoid contaminating soil or releasing this material into sewage and drainage systems and bodies of water. Do not breathe oil mist at concentrations above the recommended mineral oil mist exposure limit. Electrostatic charge may accumulate and create a hazardous condition when handling this material. To minimize this hazard, bonding and grounding may be necessary but may not, by themselves, be sufficient. Review all operations which have the potential of generating and accumulating an electrostatic charge and/or a flammable atmosphere (including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck operations) and use appropriate mitigating procedures. Container is not designed to contain pressure. Do not use pressure to empty container or it may rupture with explosive force. Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other sources of ignition. They may explode and cause injury or death. Empty containers should be completely drained, properly closed, and promptly returned to a drum reconditioner or disposed of properly. Consider the potential hazards of this material (see Section 3), applicable exposure limits, job activities, and other substances in the work place when designing engineering controls and selecting personal protective equipment. If engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal protective equipment listed below is recommended. The user should read and understand all instructions and limitations supplied with the equipment since protection is usually provided for a limited time or under certain circumstances. Use in a well-ventilated area. No special eye protection is normally required. Where splashing is possible, wear safety glasses with side shields as a good safety practice. No special protective clothing is normally required. Where splashing is possible, select protective clothing depending on operations conducted, physical requirements and other substances in the workplace. Suggested materials for protective gloves include: 4H (PE/EVAL), Nitrile Rubber, Silver Shield, Viton. No respiratory protection is normally required. If user operations generate an oil mist, determine if airborne concentrations are below the occupational exposure limit for mineral oil mist. If not, wear an approved respirator that provides adequate protection from the measured concentrations of this material. For air-purifying respirators use a particulate cartridge. 12 APRIL 20, 2015 3 of 8 7721 Use a positive pressure air-supplying respirator in circumstances where air-purifying respirators may not provide adequate protection.
