The Sun Coast Remediation Methods Presentation

SUNCOAST Suncoast Remediation Research Project AGENDA Introduction Literature Review Research Methodology, Design, and Methods Research Questions and Hypotheses Data Analysis Findings Recommendations Project Takeaways References INTRODUCTION There is a concern that jobsite particle pollution is adversely impacting employee health. There is a concern that safety training effectiveness is related to lost time hours. There is a concern that the company should upgrade to earmuffs to protect workers from sound level exposure. It is necessary to know if the revised training program is more effective than the prior training program. It is necessary to determine if blood lead levels have increased due to exposure. If return on investment is not the same for all lines of service, it would be helpful to know where differences exist. INTRODUCTION PROJECT OBJECTIVES 1 Determine if particulate matter (PM) size has impacted employee health. 2 Determine if lost time incidents are reduced by effective safety training. 3 Determine if upgrading to earmuffs is necessary to reduce noise exposure. 4 Analyze past and current new employee training programs to conclude which program is most effective. 5 6 Determine whether lead levels have increased in relation to exposure. Determine if the return of investment is the same for air monitoring, soil remediation, water remediation and health and safety training. LITERATURE REVIEW Sun Coast is concerned with worker health and safety with respect to compensation costs and potential long-term litigation from injuries and illness related to employment. In the article Current Research and Opportunities to Address Environmental Asbestos Exposures, examines how asbestos-related diseases continue to result in approximately 120,000 deaths every year in the United States and worldwide (Carlin et al, 2015). The results of the study determined that assessment is crucial to reducing exposure. When discussing safety training and lost time, enforcement of effective safety training is necessary through audits and discipline. A study, conducted by W.E Daniell, found noise reduction programs improve the routine utilization of hearing protection. The study also found that hearing protection utilization at lower Db levels would benefit employees further (W. E. Daniell et al, 2006). LITERATURE REVIEW CONT’D In research of Dostie (2018), he indicated that a workplace that provides the training for employees on innovations has innovation point higher than one that does not train its workers around of 4.6 to 6.1 percentage. A study conducted in 2017 by Li Li and Xingjie concluded that lead exposure can lead to abnormalities in ECG as well as elevated blood levels(Li Li, Xingjie, 2017). Return on investment is evaluated monetarily but one can also take into account, the value added to the firm able to supply multiple product lines.

DATA ANALYSIS Particulate Matter Safety Training Effectiveness Correlation Simple Regression Data was consistent with normal distribution and parametric testing were met Data was consistent with normal distribution and parametric testing were met The null hypothesis was rejected The null hypothesis was rejected DATA ANALYSIS CONT’D Sound-Level Exposure New Employee Training Multiple Regression Independent Samples t Test Data was consistent with a normal distribution and parametric statistical testing were met Data was not consistent with a normal distribution and parametric statistical testing were met The null hypothesis was rejected The null hypothesis was rejected DATA ANALYSIS CONT’D Lead Exposure Return on Investment Dependent Samples (Paired Samples) t Test One-Way ANOVA The data was consistent with normal distribution, and parametric statistical testing were met The null hypothesis was accepted The data was consistent with normal distribution, and parametric statistical testing were met The null hypothesis was rejected FINDINGS Determine if PM size has impacted employee health. Are lost time incidents reduced by effective safety training? Determine if upgrading to earmuffs is necessary to reduce noise exposure. There is a correlation between PM size and sick days. There is an inverse relationship between lost time incidents and safety training. Evaluate all job site micron levels to determine protection needs. This means more safety training less lost time incidents/hours. The results of the statistical testing indicated there is statistical data to prove a relationship between DB level and work environments. Evaluate all job site noise levels to determine protection needs. FINDINGS CONT’D Is the current new employee training more effective? Have lead levels increased in relation to exposure? Is the difference between the return on investment and all service lines? Scores improved from the previous training program to the new training program. The results of the statistical testing indicate there is no statistical relationship among employees pre-exposed to lead and employees post-exposed to lead. There is a difference between the ROI for service lines. The findings mean the new program is effective since test scores are higher since implementation. The findings show no correlation between exposure and increased lead levels, no further action is necessary. Water remediation and health and safety training have the lowest ROI. Particulate Matter Test and monitor all job sites to ensure the right PPE is worn at all times. Procure required respiratory protection in accordance with micron levels. Safety Training Effectiveness Increase safety training, audits and disciplinary action for safety infractions. Sound Level Exposure Test and monitor all job sites to ensure the right PPE is worn at all times. Procure required hearing protection in accordance with noise levels over 85dB per OSHA. New Employee Training The current training program should be utilized and revised/updated as necessary. RECOMMENDATIONS RECOMMENDATIONS CONT’D Lead Exposure The current procedures are successful. Update procedures as necessary. Return on Investment Water remediation and health and safety training service lines should be evaluated for improvements that can increase their perspective ROI through cost analysis. Leadership should decide from those results if each service line is necessary and adds value to the company. PROJECT TAKEAWAYS • Data analysis utilizing Excel was the most valuable skill I acquired from the project. I can utilize those tools when evaluating training/teaching materials in the future.

Thus, the company specializes in dealing with sites that containing high levels of toxic wastes and water. As a result, the company’s employees may be exposed to various substances that may impede their productivity. The company was concerned that its employees were affected by various contaminants. These concerns had a secondary effect on the overall return on investment. The senior leadership of the company conducted a study investigating various factors, including the effect of particulate matter on employee health, the impact of safety training on lost time hours, lead exposure rates before and after training, return on investment on each investment line. The results are indicated below. THE SUN COAST ORGANIZATION 6 Introduction Sun Coast leadership has identified several factors which affect the normal working of the company. Some of the identified factors directly deal with employee health and productivity, while other deal with the return on investment. The paper below analyzes the impact of each factor. The problem will be identified, the literature reviewed, a proper methodology selected to analyze the issues, and the data analyzed. The findings and recommendations will inform the next move. Statement of Problem The Sun Coast Organization management identified six main issues affecting the company. These factors included particulate matter in the immediate working environment, lack of safety training, noise exposure, lead exposure, and issues relating to return on investment. The literature review below describes all of the above issues. Literature Review Particulate Matter (PM) A study by Hamanaka and Mutlu (2018) reveals that PM air pollution significantly impacts morbidity and mortality levels. An in-depth analysis of the effects of PM air pollution by the two senior members of the medical department at the University of Chicago also reveals that the size of the PM particles plays a vital role in determining the severity of the overall health-risk posed. PM air pollutants have been attributed to various illnesses, including diabetes mellitus, respiratory diseases, deep vein thrombosis, and neurological diseases. Moreover, as part of their work’s underlying purpose, Hamanaka and Mutlu (2018) have revealed that PM air pollution has substantial impacts on the affected individuals’ cardiovascular system. Hamanaka and Mutlu (2018) posit that there are three categories of PM particles, including the coarse (
