ICHCA International <strong>Safe</strong>ty Panel Briefing Pamphlet No 30<br />
14.4 In judging whether a tank container is safe to enter, it should be born in mind<br />
that the vapours <strong>of</strong> many liquid chemicals and gases are heavier than air so<br />
that pockets <strong>of</strong> such gases can exist even in the upper air space is considered<br />
to be safe,<br />
14.5 Therefore inspecting the interior should not be done until the container has<br />
been certified to be safe to enter. This requires a test by a specialist and the<br />
use <strong>of</strong> personal protection equipment by properly trained operatives.<br />
14.6 If the interior <strong>of</strong> the tank container requires inspection or even if the access<br />
hatch needs to be opened then this should only be done by, or under the<br />
supervision <strong>of</strong>, specialist operatives normally found at tank cleaning stations.<br />
Under no circumstances should stevedores, dockworkers, ships crew,<br />
transport workers or customs <strong>of</strong>ficials who have not been properly<br />
trained and equipped open any tank container even if the container is<br />
declared as “empty”.<br />
