A. No
				employee shall be permitted an exposure to noise in excess of that specified in

				meter meeting specifications contained in "American National Standard
				Specification for Sound Level Meters," which is hereby incorporated by
				reference and made a part hereof, or by a dosimeter with similar accuracy. This
				publication may be examined in the Arizona State Mine Inspector's

No exposure shall exceed 115 dBA. Impact or impulsive noises
				  shall not exceed 140 dB, peak sound pressure level.
NOTE: When the daily exposure is composed of two or more
				  periods of noise exposure at different levels, their combined effect shall be
				  considered rather than the individual effect of each. If the sum
(Cl/Tl) + (C2/T2) + . . . (Cn/Tn)
exceeds unity, then the mixed exposure shall be considered to
				  exceed the permissible exposure. Cn indicates the total time of exposure at a
				  specified noise level, and Tn indicates the total time of exposure permitted at
				  that level. Interpolation between tabulated values may be determined by the
				  following formula:
log T = 6.322 - 0.0602 SL
There T is the time in hours and SL is the sound level
				  dBA.
B. When employees' exposure
				exceeds that listed in the above table, feasible administrative or engineering
				controls shall be utilized. If such controls fail to reduce exposure to within
				permissible levels, personal protective equipment shall be provided and used to
				reduce sound levels to within the levels of the table.
