§ 245.118 Hearing acuity. ( a ) After FRA has approved a railroad's dispatcher certification program, the railroad shall determine, prior to issuing any person a dispatcher certificate, that the person meets the standards for hearing acuity prescribed in this section and appendix B to this part.
( b ) Any examination required under this section shall be performed by or under the supervision of a medical examiner or a licensed physician's assistant.
( c ) Except as provided in paragraph (d) of this section, each dispatcher shall have hearing acuity that meets or exceeds the following thresholds with or without use of a hearing aid: The person does not have an average hearing loss in the better ear greater than 40 decibels at 500 hertz (Hz), 1,000 Hz, and 2,000 Hz. The hearing test or audiogram used to show a person's hearing acuity shall meet the requirements of one of the following: ( 1 ) As required in 29 CFR 1910.95(h) (Occupational Safety and Health Administration);
( 2 ) As required in § 227.111 of this chapter; or
( 3 ) Conducted using an audiometer that meets the specifications of, and is maintained and used in accordance with, a formal industry standard such as American National Standards Institute (ANSI) S3.6, “Specifications for Audiometers.”
( d ) A person not meeting the thresholds in paragraph (c) of this section shall, upon request of the certification candidate, be subject to further medical evaluation by a railroad's medical examiner to determine that person's ability to safely perform as a dispatcher. In such cases, the following procedures will apply: ( 1 ) In accordance with the guidance prescribed in appendix B to this part, a person is entitled to: ( i ) One retest without making any showing; and
( ii ) An additional retest if the person provides evidence that circumstances have changed since the last test to the extent that the person may now be able to safely perform as a dispatcher.
( 2 ) The railroad shall provide its medical examiner with a copy of this part, including all appendices.
( 3 ) If, after consultation with a railroad officer, the medical examiner concludes that, despite not meeting the threshold(s) in paragraph (c) of this section, the person has the ability to safely perform as a dispatcher, the railroad may conclude that the person satisfies the hearing acuity requirements of this section to be a certified dispatcher. Such certification will be conditioned on any special restrictions the medical examiner determines in writing to be necessary.
( e ) To make the determination required under paragraph (a) of this section, a railroad shall have on file the following for each certification candidate: ( 1 ) A medical examiner's certificate that the candidate has been medically examined and either does or does not meet the hearing acuity standards prescribed in paragraph (c) of this section.
( 2 ) If needed under paragraph (d) of this section, a medical examiner's written professional opinion which states the basis for their determination that: ( i ) The candidate can be certified, under certain conditions if necessary, even though the candidate does not meet the hearing acuity standards prescribed in paragraph (c) of this section; or
( ii ) The candidate's hearing acuity prevents the candidate from being able to safely perform as a dispatcher.
( f ) If the examination required under this section shows that the person needs a hearing aid to meet the standards for hearing acuity prescribed in this section and appendix B to this part, that person shall use a hearing aid at all times while performing as a dispatcher unless the railroad's medical examiner subsequently determines in writing that the person can safely perform as a dispatcher without a hearing aid.
( g ) When a certified dispatcher becomes aware that their hearing has deteriorated, they shall notify the railroad's medical department or other appropriate railroad official of the deterioration. Such notification must occur prior to performing any subsequent service as a dispatcher. The individual cannot return to service as a dispatcher until they are reexamined and determined by the railroad's medical examiner to satisfy the hearing acuity standards prescribed in this section and appendix B to this part.
( h ) Each railroad shall adopt and comply with a program meeting the requirements of this section. When any person (including, but not limited to, each railroad, railroad officer, supervisor, and employee) violates any requirement of a program which complies with the requirements of this section, that person shall be considered to have violated the requirements of this section.
