Occupational Noise Exposure
Released by: U.S. Department of Labor Occupational Safety & Health Administration (OSHA)
Paragraph 1910.95(c) (1)
The employer shall administer a continuing, effective hearing conservation program, as described in paragraphs (c) through (o) of this section, whenever employee noise exposures equal or exceed an 8-hour time-weighted average sound level (TWA) of 85 decibels measured on the A scale (slow response) or, equivalently, a dose of fifty percent. For purposes of the hearing conservation program, employee noise exposures shall be computed in accordance with appendix A and Table G-16a, and without regard to any attenuation provided by the use of personal protective equipment.
In Other Words
Whenever noise exposure levels exceed an 8-hour, time-weighted average sound level of 85 dB(A), employers should implement a noise conservation program, in order to protect employees from hearing damage.
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.
