OSH 4308 Unit IV Project Michael MirandaColumbia Southern University Be safe consulting Inc. was tasked to work for Acme manufacturing Co. to evaluate the noise levels and if they were or are hazardous. Also, to identify employees that could be affected by the noise levels during their shift. Acme must do this in order to ensure that they can mitigate employee hearing loss. through hearing conservation programs and training We will be evaluating the Machine shop using the samples that were collected during our sample testing. Although we will not be combining noise levels to get a more accurate reading of the machine shop.

But without combining dBA level we cannot determine if it is necessary all of the time or only partially.Carpentry shop #2Next, we will be tasked to study the #2 Carpentry shop containing these six machines running constantly table saws, jointers, planners, drill press and the exhaust systems. A determination must be made if the shop is a hazardous noise area since there are 10 employees working in the area. there is some importance to doing this since the employees may need to be also added to the hearing protection program (Unit IV) Machine Noise Level (dBA) Table Saw #3 92 dBA Jointer #4 87 dBA Table Saw #5 90 dBA Exhaust Ventilation System 80 dBA Planer #2 84 dBA Drill Press #1 79 dBA Unit IV given values Formula for analysis from (Yates 2015)    (Unfortunately, I did not know how to use this method to calculate the dBA so I used the lengthier method I did want to include what the formula should look like so as to calculate it properly ) Or alternately you can subtract dBA reading on machine1 from machine2 and look at the table on page 277of our text book Yates 2015. We then add that number to the higher decibel level and we continue this through all machines. Machine Noise Level (dBA) Table Saw #3 92 dBA Jointer #4 87 dBA 92-87=5 92+1.2=93.2 Table Saw #5 90 dBA 93.2-90=3.2 93.2+1.8=95 Exhaust Ventilation System 80 dBA 95-80=15 0+95=95 Planer #2 84 dBA 95-84=9 .5+95=95.5 Drill Press #1 79 dBA 79-95.5=16.5 95.5-0=95.5 The total for all of the machines combined is equal to 95.5 dBA combined would require to be part of a hearing conservation program and hearing protection worn when working or entering this area. Lastly, we will be looking at the Electronic repair shop. converting the SPL to W/ as requested by the project engineer. Since they are considering remodeling and installing
noise insulation in the shop.

The machine shop depending on the process could not be required to wear hearing protection continuously, but employees in this area should be trained and monitored in the hearing conservation program. Hearing protection should be available to them and in close proximity or worn on the employee to be used as needed. The carpentry shop is in definite need of hearing conservation programs. since the average combined dBA in the shop is 95.5 dBA. this should be done as soon as possible and all employees in the shop should be trained on the proper wear of PPE.Appendices Sample 1 T1= = = = 24.25147Hrs x 60Min =1455.0882min Sample 2 T2= = = = 6.9644Hrs x 60Min = 417.864 Min Sample 3 T3= = =  = 21.11213Hrs x 60Min =1266.7278Min Appendix A Sample 1 6.2% Sample 2 29.9% Sample 3 20.9% Appendix B Sample1 Sample 2 =2205.48min Sample 3 = =1165.62min Appendix C Sample1 27.44% Sample2 =11.2902% 11.3% Sample3 =8.23596% 8.24% Appendix D Sample 1 T1= = = = 64hrs x 60Min =3840min Sample 2 T2= = = = 4.5948hrs x 60Min = 275.688min Sample 3 T3= = =  = 18.37917hrs x 60Min =1102.74min Appendix E Sample1 7.37% Sample2 =14.1464% 14.1% Sample3 =7.61739% 7.6% Appendix F Sample 1 T1= = = = 21.11213hrs x 60Min =1266.7278min Sample 2 T2= = = = 84.44851hrs x 60Min = 5066.910min Sample 3 T3= = =  = 4hrs x 60Min =240 min Appendix G Sample1 8.9% Sample2 =4.71689%% 4.7% Sample3 =52.916% 52.9% Appendix H Sample 1 T1= = = = 84.44851hrs x 60Min = 5066.910min Sample 2 T2= = = = 2205.48min Sample 3 T3= = = = 21.11213Hrs x 60Min =1266.7278Min Appendix I Sample1 4% 203Sample2 =7.79876% 7.8% Sample3 =8.28907% 8.3% Appendix JReferencesYates, W.
