Occupation Health And Safety Journals Question Discussions
For many chemicals, the ACGIH TLVs and NIOSH RELs are much more restrictive than existing OSHA PELs. The differences are typically based on the use of more recent scientific data. State your case as to whether employers should use the most restrictive of the PELs, RELs, or TLVs, or if you believe the employer should only have to use the legally enforceable PELs. Please connect your personal experiences or what you have researched regarding this concept. 200 wdsThe placement of the industrial hygiene and safety functions in an organization's structure can greatly impact how successful the programs will be. Some organizations place health and safety programs under the human resources department. Other organizations place these programs under the plant manager or the production manager. If you were a safety officer for an organization, where would you place health and safety programs in the organizational structure? Explain why you believe this placement would work best for your organization. 200 wdsYou have been asked to perform a job hazard analysis (JHA) at your place of employment. Which method would you use to perform the JHA? Explain your choice. 200 wdsDiscuss a gas or vapor that you have dealt with in a workplace. Include information about how worker exposures were evaluated. If you have never had sampling for a gas or vapor performed in your workplace, review either the NIOSH Manual of Analytical Methods (NMAM) or the OSHA Sampling and Analytical Methods, and choose a vapor or gas that looks interesting to you. 200 wdsThe current OSHA permissible exposure limit (PEL) for nuisance dust is 15 mg/m3 as an 8-hour time-weighted average (TWA) exposure. The ACGIH has published a threshold limit value (TLV) for inhalable dust of 10 mg/m3. OSHA is required to consider economic and feasibility influences as well as health impacts for establishing or updating PELs. The ACGIH can consider only the health impacts when establishing TLVs. Imagine you are a safety officer having to establish an occupational exposure limit (OEL). Discuss how you would come to this exposure limit.200 wdsOSHA uses a 5 dBA exchange rate, meaning that the allowed exposure time is cut in half for every increase in exposure of 5 dBA. ACGIH and NIOSH recommend a 3 dBA exchange rate because noise energy exposure actually doubles every 3 dBA. OSHA explains the use of the 5 dBA exchange rate as a means to account for the time during a workday that the employee is not exposed to noise, like breaks. Imagine you are a safety officer who has to choose which exchange rate is preferable to use at your organization. Discuss in your journal entry whether the 5 dBA or the 3 dBA exchange rate should be used for controlling occupational noise exposure. 200 wdsImagine that you are a safety officer, and you have been asked to recommend a type of ventilation system for your company. Which one would you choose, and why? 200 wdsOSHA allows respirator fit testing to be performed using either qualitative fit testing (QLFT) methods or quantitative fit testing (QNFT) methods that are specified in Appendix A of 29 CFR 1910.134. Discuss the fit testing methods with which you are familiar and which methods you prefer to use. If you have never been fit tested or performed fit testing, read Appendix A and discuss which of the methods you believe would be the easiest to perform. Give the reasons for your choice.Part A: You are the Environmental Coordinator for a demolition company that still prefers the use of dynamite sticks for demolition. You are tasked with the compliant and safe transport of dynamite to the demolition sites. Identify the proper placarding, labeling, and shipping documentation of the transport vehicle as required by the DOT. Part B: The vehicle that was transporting the dynamite sticks in Part A has been struck by another vehicle. A small fire appears to be spreading from a tire on a vehicle at the scene of the accident. Identify the explosive material that could be involved, and describe the chemical interaction that could be occurring as a result of the collision between the two vehicles. What immediate action should the EHS and FS responders take to protect human health and the environment? Your response should consist of at least 200 words. How can you apply what you learned in this course to your career or life success?

Stratford University Importance of Measures of Center and Variation Discussion
A. Welcome to the final project. Introduce your scenario and data set.Provide a brief overview of the scenario you are given above and the data set that you will be analyzing.Classify the variables in your data set.Which variables are quantitative/qualitative?Which variables are discrete/continuous?Describe the level of measurement for each variable included in your data set.Discuss the importance of the Measures of Center and the Measures of Variation.What are the measures of center and why are they important?What are the measures of variation and why are they important?Calculate the measures of center and measures of variation. Interpret your results in context of the selected topic.MeanMedianModeMidrangeRangeVarianceStandard DeviationDiscuss the importance of constructing confidence intervals for the population mean.What are confidence intervals?What is a point estimate?What is the best point estimate for the population mean? Explain.Why do we need confidence intervals?Based on your selected topic, evaluate the following:Find the best point estimate of the population mean.Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown.Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.Write a statement that correctly interprets the confidence interval in context of your selected topic.Based on your selected topic, evaluate the following:Find the best point estimate of the population mean.Construct a 99% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown.Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.Write a statement that correctly interprets the confidence interval in context of your selected topic.Compare and contrast your findings for the 95% and 99% confidence interval.Did you notice any changes in your interval estimate? Explain.What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain.Discuss the process for hypothesis testing.Discuss the 8 steps of hypothesis testing?When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?Perform the hypothesis test.If you selected Option 1:Original Claim: The average salary for all jobs in Georgia is less than $65,000.Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.If you selected Option 2:Original Claim: The average age of all patients admitted to the hospital with infectious diseases is less than 65 years of age.Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.Based on your selected topic, answer the following:Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.Is the test two-tailed, left-tailed, or right-tailed? Explain.Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic? What is the P-value?What is the critical value?What is your decision; reject the null or do not reject the null?Explain why you made your decision including the results for your p-value and the critical value.State the final conclusion in non-technical terms.ConclusionRecap your ideas by summarizing the information presented in context of your chosen scenario.Option 1Data set for option 1Option 2Data set for option 2B. this last discussion forum, I'd like for you to reflect on the course as a whole. What did you like? What did you not like? What did we need to spend more time on in class? What could've been relegated to doing outside of classes or skipped entirely?Please feel free to be open on this, because any feedback you provide can be used to better improve future course sessions!
