if it is necessary all of the time or only partially.

Next, 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)

(Unfortunately, I did not know how to use this method 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.

18. In conclusion the two initial assessments done in the machine
shop and in the carpentry shop I have concluded that both of
those areas need to be a part of the hearing conservation
program. 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.

After receiving good remarks from your previous work, you
hear that Acme Manufacturing Co. has asked you and BSCI to
return for some additional work. BSCI has been contracted by
Acme Manufacturing Co. to conduct a study to determine
employee exposures to noise. In addition, Acme Manufacturing
Co. has requested that, while on site, you conduct a needs
analysis to determine the development of a new safety training
program, exhibiting training and management techniques.
Explain your methodology and the steps in conducting this
