Question 1 (Part 1)

Have you experienced an environment which posed potential thermal stressors? Describe an example (i.e., fictitious or actual) of an environment posing potential thermal stressors. Then, share a few thoughts about how you could prevent injuries from occurring in that environment.
 

Your journal entry must be at least 200 words. No references or citations are necessary.

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.

Based on this information, determine which category each security location is exposed to and make a recommendation as to what changes, if any, you would make.
 

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 page and appendices).

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

Question 2 (Part 1)

What areas in your current work environment involve the use of hydrostatics or hydraulics to make the systems work? If you are not employed, nor have a work environment, use your home or past employment environment to discuss this topic.
 

Your journal entry must be at least 200 words. No references or citations are necessary.

Question 2 (Part 2)

Instructions

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. Prior to its turn to a horizontal direction, the pipe is 18 inches in diameter and 60 ft. long. 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?

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).
