OSHA 1910.95(b)(1)

Occupational Noise Exposure
Released by: U.S. Department of Labor Occupational Safety & Health Administration (OSHA)

Paragraph 1910.95(b) (1)
When employees are subjected to sound exceeding those listed in Table G-16, feasible administrative or engineering controls shall be utilized. If such controls fail to reduce sound levels within the levels of Table G-16, personal protective equipment shall be provided and used to reduce sound levels within the levels of the table.

In Other Words
Controls need to be utilized when employees are subjected to sound exceeding listed levels; otherwise protective equipment must be utilized.

Compliance of CEJN Pneumatic Safety Products
CEJN's Series 208 blowgun with a Star-Tip complies by reducing noise levels down to 85 dB(A) or less.
CEJN vented safety couplings comply by disconnecting in two stages, thereby reducing noise.

¼ or less                                              115

Footnote (1):  When the daily noise exposure is composed of two or more periods of noise exposure of different levels, their combined effect should be considered, rather than the individual effect of each. If the sum of the following fractions:  C(1) / T(1) + C(2) / T(2)  C(n) / T(n) exceeds unity, then, the mixed exposure should be considered to exceed the limit value. Cn indicates the total time of exposure at a specified noise level, and Tn indicates the total time of exposure permitted at that level.  Exposure to impulsive or impact noise should not exceed 140 dB peak sound pressure level.
