Approval o
5、f an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, directly and materially affe
6、cted interests have reached substantial agreement. Substantial agreement means much more than a simple majority, but not necessarily unanimity.

12、inted in the United States of America American National Standard Foreword (This Foreword is not a part of American National Standard A10.46 2013.) This standard is one of a series of safety standards that have been formulated by the Accredited Standards Committee on Safety in Construction and Demoli
13、tion Operations, A10. It is expected that the standards in the A10 series will find a major application in industry, serving as a guide to contractors, labor and equipment manufacturers. For the convenience of users, a list of existing and proposed standards in the A10 series for Safety Requirements
14、 in Construction and Demolition Operations follows. A10.1 Pre-Project or the hearing threshold shown in the annual audiogram indicates signifi-cant improvement over the baseline audiogram. 6.9 If a STS occurs, a retest may be administered within 30 days to determine if the shift is persistent. Retes
15、ting the same day to confirm STS is acceptable, cost effective and recommended. If the shift persists, the results should be reviewed by an audiologist or physician who has the appropriate licensure and training to interpret audiograms and may be designated by the reviewing audiologist or physician
16、as the employees new baseline. Unless the shift is found to be unrelated to noise by the reviewer, the employer shall record the shift in the workers medical record, and the worker shall be informed in writing of the existence of a STS within 21 calendar days of the determination. The AMERICAN NATIO
17、NAL STANDARD A10.46 2013 15 audiogram confirming a shift should be used as a revised baseline for future audiometric tracking. The employer shall take appro-priate action to protect the worker from additional hearing loss due to occupational noise exposure, including reinstruction and refitting of h
18、earing protectors. 6.10 An employee does not need to be tested if documentation is available indica-ting they had a comparable test within the previous 12 months. 7. TRAINING 7.1 Employers shall provide and document training to all employees covered by this standard within 30 days of hire and at lea
19、st annually. Training in proper use of hearing protection will improve fit and protection. Training shall be conducted prior to first exposure at or above 85 dBA. This training should include: 7.1.1 Hazards of exposure to both occupational and non-occupational noise; 7.1.2 Where and when workers are
20、 likely to have exposures at or above 85 dBA and how they can recognize this situation; 7.1.3 Noise control measures that the employer can use; 7.1.4 Selection, attenuation, fitting and care of available hearing protection; 7.1.5 Inspection of HPDs to determine when they should be discarded and repl
21、aced as damage, deformation, cracks, unusual hardness and dirt can affect fit and protection; 7.1.6 The purpose and procedures of audiometric testing and importance of observing quiet time before testing; and 7.1.7 The early symptoms of hearing loss. 8. RECORDKEEPING 8.1 Audiometric records shall be
22、 preserved and maintained for at least the duration of employment. Records of noise measurements used for exposure estimation, training records and program evaluations shall be preserved and maintained for a minimum of two years. 8.2 Audiometric test records shall only be accessible to appropriate p
23、rogram personnel, affected current or former employees and authorized regulatory personnel, and only with employee permission. Note: Federal, state or local laws may restrict sharing of medical information that can be identified by an individuals name or job, and the reader is advised that the law i
24、n its jurisdiction must be followed. 8.3 Centralized and multiple contractor audiometric database storage whether by an employer or a third party administrator is permissible as long as the other requirements of this section are met. 9. EVALUATION 9.1 Annual evaluations of the hearing conservation p
25、rogram shall be conducted by the employer to assess the effectiveness of measures taken to reduce hearing loss. The evaluations may include, but are not limited to the following annual comparisons: 9.1.1 Number or rate of workers developing an STS; 9.1.2 Number or fraction of workers exposed above 8
26、5 dBA; 9.1.3 Number and types of equipment used that are capable of producing exposures above 85 dBA; 9.1.4 Rate of use of HPDs among exposed workers; 9.1.5 TWA exposure levels; and AMERICAN NATIONAL STANDARD A10.46 2013 16 9.1.6 Measured personal attenuation levels from user subject fit test of HPD
27、s. 9.2 When evaluation metrics show no improvement or a decline in hearing conservation efforts, hearing protection training programs and noise control measures shall be revised. 10.
