12 Completion and permit closure<br />
Certain checks need to be done after tank entry.<br />
On expiry of the permit-to-work, everyone should leave the space, and openings<br />
should be closed or otherwise secured against entry.<br />
At the end of the work, the permit must be closed and signed off. Where work is ongoing but the permit<br />
period expires, an extension can be provided in the form of a new permit.<br />
Where an extension is required, the safety measures originally taken must be reconfirmed and entry must<br />
be reapproved.<br />
Before closing the space, the responsible officer should check to confirm that all people and equipment<br />
have been removed.<br />
The entrance to the space should never be left unattended while open, without measures having been<br />
taken to prevent unauthorised access. This is particularly important where the access is on the deck, as<br />
there is a risk that somebody may fall in to the space.<br />
Example incident<br />
A stevedore onboard a container ship in a UK port fell through the manhole of a ballast tank that had been<br />
left open and unguarded. Fortunately, the ballast tank was full and the stevedore fell into the water. He<br />
managed to swim to the surface and escape unharmed through the manhole.<br />
