-You are a supervisor responsible for completing the repair of an installed utility line that cannot be removed in an equipment room where the ambient noise level is 100 dBA and the other equipment cannot be shut down. While not a confined space, the nature of the area itself is only large enough for one person to be able to work at a time. While the work is projected to require no more than 6 hours to complete, it is necessary to complete the work in that same shift. You have three skilled trades technicians who are all cross-trained and certified to do the work. Even though you issue appropriate P.P.E. your company policy is to not rely solely on P.P.E.

4. What is the PEL for noise that any one of the technicians could be exposed to during the repair if they were not wearing P.P.E. (NOTE - be sure to cite the relevant OSHA standard for credit; 2 points possible)?

5. What approach would you take to minimize the risk for any of the technicians, please explain your reasoning (1 point possible).
