<p>A whistle shall be placed as high as practicable on a
vessel in order to reduce interception of the emitted
sound by obstructions and also to minimize hearing
damage risks to personnel.
The sound level of the vessel’s own signal at listening
posts shall not exceed 110 dB(A) and as far as
practicable should not exceed 100 dB(A).</p>

<p>(f) A vessel at anchor shall at intervals of not more
than one minute ring the bell rapidly for about 5
seconds. In a vessel of 100 metres or more in
length the bell shall be sounded in the forepart of
the vessel and immediately after the ringing of
the bell the gong shall be sounded rapidly for
about 5 seconds in the after part of the vessel. A
vessel at anchor may in addition sound three
blasts in succession, namely one short, one prolonged
and one short blast, to give warning of
her position and of the possibility of collision to
an approaching vessel.</p>

<p>(g) A vessel aground shall give the bell signal and if
required the gong signal prescribed in paragraph</p>
