12.5.4 Portable Electrical Equipment
The use of portable electrical equipment, other than approved air driven
lamps, should be prohibited in holds or spaces containing packaged
petroleum or other flammable liquids, or on deck or in spaces over or
adjacent to such holds or spaces, unless the ship complies with the
conditions for the use of such equipment on tankers (see Section 4.3).

When packaged petroleum or other flammable liquids are being handled,
the control valves of any smothering system in the holds should be
closed and precautions taken to prevent unauthorised or accidental

operations, and after hatches have been secured, any previously isolated
fixed smothering system should be returned to operational readiness.

12.5.6 Fire-Fighting Precautions

In addition to the precautions outlined in Section 24.8, at least two dry
chemical fire extinguishers, together with fire hoses equipped with spray
nozzles, should be ready for use while cargo handling is taking place.

12.5.7 Forecastle Spaces and Midship Stores

Packaged petroleum or other flammable liquids should not be carried in
the forecastle spaces, midship stores or any other space unless such
spaces have been specifically designed and classified for the purpose.

12.5.8 Deck Cargo

When drums or other receptacles are carried on deck, they should be
given protection against the sea and weather, and normally be stowed
only one tier high.

All packages should be stowed well clear of all deck fittings, including
tank and valve controls, fire hydrants, safety equipment, steam pipes,
deck lines, tank washing openings, tank vents, hatches, doorways,
emergency exits and ladders. They should be provided with adequate
dunnage and be properly secured to strong points on the ship’s structure.

12.5.9 Barges
Barge personnel should comply with the relevant requirements of
Chapter 4, particularly with regard to restrictions on smoking, naked lights
and the use of cooking appliances. If alongside a tanker, they should also
comply with any requirements contained in Chapter 24. During the hours
of darkness, barges containing packaged petroleum or other flammable
liquids should only be allowed to remain alongside a tanker if adequate
safe illumination is provided and there are means of ensuring compliance
with smoking restrictions and other safety requirements.
