A worker exposure to noise is given plant is measured, resulting in the following readings for various time periods during 8-hour shift?
8:00 A.M-9:00 A.M. 86 dBA
9:00 a.m.-11:00 a.m. 84 dBA
11:00 am-12 noon 80 dBA
12 NOON-1:00 PM 101 dBA
1:00 pm-4:00 p.m. 75 dBA
Perform the computations to determine whether maximum PELs have bee exceeded?
Have the ALs being exceeded?
Given the noise exposure just described, would the employer be required to furnish hearing protectors
Would employees be required to use the hearing protector?
Suppose that the engineering control could be devised that would cut the noise level (sound exposure level) in half either in the morning or in the afternoon but not in both. Which would you select? Why?
