INTERNATIONAL SAFETY GUIDE FOR OIL TANKERS AND TERMINALS

Oil spillage and leakage present a fire hazard and can lead to pollution. They
can also cause slips and falls. Spills and leaks should therefore be avoided
---ใช้เพื่อการศึกษาเท่านั้น---
and, if they occur, immediate attention should be given to stopping the source
and to cleaning contaminated areas.

4.2 Control of Potential Ignition Sources

4.2.1 Naked Lights

Naked lights must be prohibited on the tank deck and in any other place where
there is a risk that petroleum gas may be present.

4.2.2 Smoking

Smoking is known to present significant risks on board ships and therefore
requires careful management. While the text of this Section refers explicitly to
smoking, the controls should also be applied to the burning of other products
such as incense and joss sticks, a practice that has become common around
the world. As with tobacco products, smouldering smoke-producing products
should never be left unattended or allowed near bedding or other combustible
materials.

4.2.2.1 Smoking at Sea

While a tanker is at sea, smoking should be permitted only at times and
in places specified by the Master. Smoking must be prohibited on the tank
deck or any other place where petroleum gas may be present. Criteria
that should be taken into account when determining the location of
designated smoking places are listed in Section 4.2.2.3.

4.2.2.2 Smoking in Port and Controlled Smoking

Smoking in port should only be permitted under controlled conditions.
Difficulties perceived in introducing a restrictive smoking policy, including a
total ban, should not impede the implementation of such a policy if it is in
the interest of safe operations. Appropriate measures should be in place,
both on the ship and the shore, to ensure full compliance.

Smoking should be strictly prohibited within the restricted area enclosing
all tanker berths and on board any tanker while at a berth, except in
designated smoking places.

Certain craft, such as barges designed without a permanent propulsion
system, may have an accommodation block or lesser structure affixed
directly to the tank deck. The spaces beneath such a structure may be
designed for the carriage of non-explosive and non-flammable products,
but this does not guarantee that such spaces remain gas free.

Some conventional vessels, typically smaller craft such as barges and
inland watercraft, are similarly at risk through their inability to maintain
positive pressure in the accommodation block and other spaces.

In such cases, the inherent difficulty in maintaining a gas free
environment either within, immediately outside or below such an
accommodation block or lesser structure makes the provision of a safe
smoking area impossible. Smoking on board such craft should be strictly
prohibited while they remain alongside the terminal or facility.
