3.14.1 In addition to the spaces referred to in
sections 3.10 to 3.13, measurements shall be taken in all locations
with unusually high noise levels where seafarers may be exposed, even
for relatively short periods, and at intermittently used machinery
locations.
3.14.2 In order to restrict the number of measurements
and recordings, noise levels need not be measured for normally unoccupied
spaces, holds, deck areas and other spaces which are remote from sources
of noise.
3.14.3 In cargo holds, at least three microphone
positions in parts of holds where personnel are likely to carry out
work shall be used.
