be robust and suitable for working in the shipboard environment, should
be of a design and construction adequate for the service for which
it is intended and should be so installed and protected as to reduce
to a minimum any danger to persons on board, due regard being paid
to hot surfaces and other hazards. The design should have regard to
materials used in construction, the purpose for which the equipment
is intended, the working conditions to which it will be subjected
and the environmental conditions on board.
4.8 The ballast water treatment equipment should
be provided with simple and effective means for its operation and
control. It should be provided with a control system that should be
such that the services needed for the proper operation of the ballast
water treatment equipment are ensured through the necessary automatic
arrangements.
4.9 The ballast water treatment equipment should,
if intended to be fitted in locations where flammable atmospheres
may be present, comply with the relevant safety regulations for such
spaces. Any electrical equipment that is part of the BWMS should be
based in a non-hazardous area, or should be certified by the Administration
as safe for use in a hazardous area. Any moving parts, which are fitted
in hazardous areas, should be arranged so as to avoid the formation
of static electricity.
