After reading the Unit IV Lesson and your assigned readings, choose three substances that w ere discussed. O ne

substance m ust be a gas/vapor hazard, one m ust be an aerosol hazard, and one m ust be a biological hazard.

W rite a m inim um of one page for each hazard you choose (a m inim um of three pages total), w hich sum m arizes the

follow ing inform ation:

Explain w hether the substance is a chem ical or biological hazard, and explain how you determ ined that.

Explain the key chem ical properties (vapor pressure, vapor density, m olecular w eight, relative size) as applicable, and

describe how these properties affect the different routes of exposure. Based on the chem ical properties, how w ould you

identify w hich exposure route is the m ost im portant?

Analyze how the substance could enter the body through the derm al route, and discuss w hy the derm al route w ould or

w ould not be im portant.

U nit VI Scholarly Activity

In the follow ing assignm ent, you w ill be given tw o different questions concerning the m aterial covered in this unit. Each

question should be answ ered using a m inim um of 250 w ords. Any resources, including your textbook, that are utilized to

answ er the questions should be cited and referenced using APA form atting. A tem plate has been provided here for you to

use to answ er the questions. Enter your answ ers into the tem plate, and upload the tem plate into the assignm ent area w ithin

Blackboard. The questions you w ill be answ ering are show n below (and in the tem plate).

The O ccupational Safety and Health Adm inistration (O SHA) currently has a perm issible exposure lim it (PEL) for noise of 90

dBA at an 8-hour tim e-w eighted average (TW A) exposure w ith an action level of 50% of that exposure. O SHA uses a 5 dB

exchange rate (doubling rate); this m eans that if the exposure increases from 90 dBA to 95 dBA, the allow ed exposure tim e

decreases to one-half— from 8 hours to 4 hours.

The National Institute for O ccupational Safety and Health (NIO SH) and the Am erican C onference of G overnm ental Industrial

Hygienists (AC G IH) recom m end using an exposure lim it of 85 dBA instead of 90 dBA and also recom m end using a 3 dB

exchange rate. These levels are m uch m ore protective than the levels currently used by O SHA.

D iscuss the m erits of each of the tw o m ethods. Provide your opinion as to w hich of the approaches you believe should be

used. Support your answ er w ith at least one professional/scholarly reference.

O SHA does not currently have a regulation specifically covering ergonom ic issues. O SHA has issued several guidelines for

som e specific industries. C onsider a w orkplace you are fam iliar w ith w here there is a potential for repetitive m otion injuries.

D iscuss w hat m ethods you w ould use to identify tasks that w ould present the greatest risk for repetitive m otion injuries. How

w ould you establish an ergonom ics program to address the issues? W hat w ould be the greatest obstacles in establishing

the ergonom ics program ?

U nit VIII R esearch Paper

For the follow ing research paper assignm ent, you have been asked to perform an evaluation of em ployee exposures at a

sm all autom obile parts m anufacturing facility. The m anufacturing processes include tw o m etal presses, tw o m achining

stations, three w elding stations, a sm all paint booth, and a shipping/receiving area. There are tw o em ployees w orking at

each press, one person w orking at each m achining station, one person w orking at each w elding station, tw o people w orking

in the paint booth, and four em ployees w orking in the shipping/receiving area.

O ne 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 m achining area uses a m etal w orking fluid. The safety data sheet (SD S) for the m etal w orking

fluid is attached here. All w elding is perform ed on stainless steel. The painting booth uses a pow der coating operation, but

the em ployees use xylene and m ethyl ethyl ketone (M EK) to clean the parts prior to the pow der coating operation. At the end

of the shift, one of the em ployees uses 1,3 butadiene to clean the nozzles for the paint booth. The facility uses tw o electric

forklifts to m ove m aterials betw een the production area and the storage w arehouse and betw een the w arehouse and the

shipping area. All em ployees w ork an 8-hour shift.

Part 1:

Using the inform ation on anticipation and control w e studied in the textbook, identify the hazards that are present in the

facility. In your discussion, explain w hy you chose the hazards, and describe w hether you believe the hazards to be actual

hazards or potential hazards (w hich require further evaluation). D escribe the specific location(s) at the facility w here the

hazards are located, and determ ine how m any em ployees are potentially at risk in those areas.

Your response for Part 1 should be at least one page in length.

Part 2:

Using the inform ation on evaluation that w e studied in the textbook, sum m arize how you w ould m easure the personal

exposures to the hazards that you identified in Part 1. Use the O ccupational Safety and Health Adm inistration (O SHA)

w ebsite (https://w w w .osha.gov/dts/sltc/m ethods/toc.htm l) or the National Institute for O ccupational Safety and Health

(NIO SH) w ebsite (http://w w w .cdc.gov/niosh/docs/2003-154/default.htm l) to select the specific sam pling and analytical

m ethod that w ould w ork best to evaluate any chem ical hazards you identified. Provide a sum m ary of the sam pling m edia

you w ould use, include the sam pling flow rate, discuss how long you w ould sam ple, and explain how you w ould calibrate the

sam pling train. Include a discussion about w hy you selected the specific sam pling and analytical m ethod.

Your response to Part 2 should be at least one page in length.

Part 3:

Access the attached sam pling results here. For each set of results, perform the follow ing actions:

C alculate the 8-hour tim e w eighted average (TW A) exposure.

C om pare the results to the appropriate O SHA perm issible exposure lim it (PEL).

D eterm ine w hich results exceed an established O SHA PEL.

W rite a one-page sum m ary of the sam pling results; docum ent the exposures that exceeded an O SHA PEL, and identify

those areas that you believe w ill require the application of controls to reduce risk. Include your calculations, include a list of

the O SHA PELs you com pared the results to, and explain how you decided that an exposure exceeded an O SHA PEL.

Part 4:

Using O SHA’s hierarchy of controls, recom m end the control m ethods that you believe w ould be the m ost effective for

reducing the risks associated w ith the exposures that exceeded the O SHA PEL above. Explain how you w ould im plem ent

the controls and how you w ould evaluate the effectiveness of the controls. Also, discuss any interim control m ethods you

w ould recom m end 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 form at.
