    19. OSHA Noise Standards

    20. The Occupational Noise Exposure Standard Derived from the Walsh-Healey Public Contracts Act. 1971 adopted under the Occupational Safety and Health Act. Permissible Exposure Level (PEL) of 90 dBA. Noises with a higher level than 90 dBA can be sustained for periods of less than 8 hours. Sounds with average levels less than 90 dBA can persist for periods of more than 8 hours.

    21. Permissible Noise Exposure

    22. Hearing Conservation Amendment Published in the Federal Register on March 8, 1983. The Hearing Conservation Amendment requires the employer to perform five key tasks: Measure Noise Audiometric Tests Hearing Protectors Education & Training Record Keeping

    23. Measuring Method for OSHA Surveys

    24. Table G-16a (abbreviated)

    25. OSHA Standard - Conclusion The focus of the Occupational Noise Exposure Standard and the Hearing Conservation Amendment, is to set minimum requirements to protect hearing for those workers in a noisy environment. The Keys to Success Positive attitude on the part of the management Clear communication of the value of hearing Hearing protection takes care of the problem of noise for the short term, but the key to real hearing protection is education and communication.

    26. ACGIH TLV® TLV of 85 decibels Three decibel exchange rate No Threshold

    27. European Noise Standard Directive 2003/10/EC of 6 Feb, 2003 Member States to Comply by 15 Feb,06 Exceptions: Seagoing Vessels – 5 extra yrs Music Industry – 2 extra years Daily Exposure Limit 8 hour TWA (LEX,8h) Weekly Exposure – Five 8-hr Days

    28. Noise Directive 2003/10/EC Brief Summary

    29. New ANSI-ASSE Noise Standard A10.46-2007 Approved March 5, 2007 Available for $63 at www.ansi.org or www.asse.org

    30. New ANSI-ASSE Noise Standard (3.1) Notable items “Employer shall identify situations, tools, tasks and work areas that may result in exposure at or above 85 dBA and determine through measurements or estimations the noise levels associated with these exposures” Raise your voice? Specific tools

    31. New ANSI-ASSE Noise Standard (3.2 and 3.3) May use sound level meters or dosimeters at or above 85 dBA “May use historical data, government guidance documents, published data or manufactures reference information to estimate exposures” Where “data shows exposures at or above 85 dBA, the employer must produce noise measurements if he or she chooses to demonstrate that a worker is typically exposed below these levels…”

    32. New ANSI-ASSE Noise Standard (3.3 note) “This standard relies on task-based exposure monitoring to identify jobs and tasks that require hearing protector use.” “OSHA standards rely on 8-hour TWA measurements (dosimetry) to trigger hearing protector use and other elements of a hearing conservation standard.”

    33. New ANSI-ASSE Noise Standard (3.3 note) - continued “This standard will require hearing protection for any period of exposure over 85 dBA. This approach does not thus require eight-hour TWA dosimetry. Some dosimetric exposure monitoring, however, may still be required to comply with OSHA regulations.”

    34. New ANSI-ASSE Noise Standard (3.4 note) Warning signs if 85 dBA is exceeded

    35. New ANSI-ASSE Noise Standard (4) Control Engineering or administrative controls for levels above 85 dBA Hearing protection shall be provided when engineering or administrative controls fail to reduce exposure to 85 dBA Double protection at 105 dBA

    36. New ANSI-ASSE Noise Standard Standard also describes Hearing Protection Devices (PPE) Audiometry Training Recordkeeping (30 years) Annual evaluation of program

    37. New ANSI-ASSE Noise Standard Examples of noise levels Air gun 108 dBA Asphalt grinder 111 dBA Backhoe 85 dBA Bulldozer 87 dBA Circular saw 88 dBA Concrete saw 98 dBA Nail gun 97 dBA
