4.1.1 The equipment should be strongly constructed
and suitable for shipboard use, bearing in mind its intended location
on the ship.
4.1.2 It 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 which
is part of the equipment 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.
4.1.3 The equipment should be so designed that
it functions automatically. However, provisions should be made for
emergency manual control.
4.1.4 Changing the feed to the oil filtering equipment
from oily-water to oil, or from oil and/or water to air should not
result in the discharge overboard of any mixture containing more than
15 ppm of oil.
4.1.5 The system should require the minimum of
attention to bring it into operation. In the case of equipment used
for engine room bilges, there should be no need for any adjustment
to valves and other equipment to bring the system into operation,
and when fitted in unattended machinery spaces the equipment should
be capable of operating for at least 24 hours of normal duty without
attention.
4.1.6 All working parts of the equipment which
are liable to wear or to damage should be easily accessible for maintenance.
