45 Bulk fodder loaded through portable piping

If bulk fodder is loaded onto a vessel through portable piping:

(a) the vehicle from which it is loaded must be earthed to a suitable part of the wharf or quay and, if a separate blower trailer is used, it also must be earthed; and

(i) the piping must be arranged so that it is electrically continuous; or

(ii) a bare wire strong enough to withstand normal handling must be wound round the full length of the pipe in spiral fashion with a pitch of approximately 500 mm; and

(c) the piping must be earthed to the vessel and all earth connections must be secured with clips so that there will be no disconnection during the handling or manoeuvring of the piping; and

(d) if more than 1 pipe length is used:

(i) the pipes must not be insulated from each other; and

(ii) each pipe length must be earthed to the adjoining length by metal straps, or earthed separately if the pipes are connected by heavy duty seals that are not electrically conductive; and

(e) a conductive sleeve approximately 500 mm long must be fitted at the discharge end of the pipe and must be electrically continuous with the pipe or the bare spiralled wire mentioned in paragraph (b)(ii).
