INTERNATIONAL SAFETY GUIDE FOR OIL TANKERS AND TERMINALS

The design of bunker tank vents and their location makes managing the
exposure to personnel more difficult, as closed loading and venting cannot

usually be implemented.

procedures should be in place to monitor and control the access of personnel
to exposure areas.
Ventilation to lower the concentration of vapour in the ullage space and in
specific areas where vapours may accumulate should be carried out as soon
as practicable.

Even after the tank has been ventilated to reduce the concentration to an

acceptable level, subsequent transfer, heating and agitation of the fuel within a
tank may cause the concentration to reappear.

Periodic monitoring of the concentration of H 2
bunker tank is refilled with a fuel oil not containing H S.
