| Content | 0335 Edition 7/2012 617.0-IFA:638.21 Protection against noise for engine drivers and engine driver/shunters Problem With enactment of the German Ordinance on noise and vibration protection (LärmVibrations- ArbSchV) in the spring of 2007, the action values for prevention measures were lowered by 5 dB(A). Hearing protection must now be made available at daily noise exposure levels of 80 dB(A) upwards, and worn from 85 dB(A) upwards. In addition, a daily noise exposure level of more than 85 dB(A) at the worker s ear has been specified as the limit exposure value. This figure takes the attenuation of hearing protection into account. Overall, the group of workers who are now required to wear hearing protection or to be offered it has been extended considerably. In the railway sector this gives rise to a conflict for engine drivers and engine driver/shunters between the requirement for hearing protection on the one hand and the essential need to perceive signals on the other. For this reason, the federal authority responsible for the railway sector wished to approve the use of hearing protection only if it is demonstrated that all signals necessary during operations can still be perceived. Activities In the first phase of a project, locations associated with noise exposure and their sources at and on tractive units were to be identified, and the noise quantified. Observation of the working procedures Shunting duty: remote control of the tractive unit from the auxiliary driving position and the various sources of noise were also to pro- vide indications of how noise could be avoided or reduced. Personal long-term measurements were per- formed by means of noise dosimeters. Putting on the dosimeter – which was attached to a belt sys- tem – and the microphone was straightforward for the workers. This was not therefore a source of problems at the beginning and end of operations, when time is frequently at a premium. The personal measurements were supplemented by stationary measurements taken with hand-held sound level meters. These enabled the noise exposure at discrete events to be recorded at a |
