INTERNATIONAL SAFETY GUIDE FOR OIL TANKERS AND TERMINALS

4.3.4 Torches (Flashlights), Lamps and Portable Battery
---ใช้เพื่อการศึกษาเท่านั้น---
Powered Equipment
Only torches that have been approved by a competent authority for use in
flammable atmospheres may be used on board tankers.

Handheld UHF/VHF portable transceivers must be of an intrinsically safe type.

Small battery powered personal items such as watches, miniature hearing aids
and heart pacemakers are not significant ignition sources.

Unless approved for use in a flammable atmosphere, portable radios, tape
recorders, electronic calculators, cameras containing batteries, photographic
flash units, portable telephones and radio pagers, however, must not be used
on the tank deck or in areas where flammable gas may be present.

Trimode gauging tapes are battery operated electronic units and should be
certified as being suitable for use in flammable atmospheres.

4.3.5 Cameras
There is a wide range of photographic equipment available. Ships and
terminals may encounter various types of camera in different situations – film
crews with complex professional equipment and large batteries or the personal
ึ
still or video equipment. The following general guidelines should be considered
when deciding whether or not it is safe to use a particular camera. This
guidance refers only to ignition hazards and does not consider security
concerns that may require other restrictions on the use of cameras in some
ports.

Camera equipment that contains batteries may produce an incendive spark
from the flash or the operation of electrically powered items, such as aperture
control and film winding mechanisms. This equipment should therefore not be
used in a hazardous area (see Section 4.4.2) unless it is certified as being
suitable for use in a hazardous area. Disposable cameras are available with a
built-in flash capability and care must be taken to ensure that these are not
used in hazardous areas.

Photographic equipment is available which does not have a flash, or any
battery or power operated parts, such as the non-flash plastic disposable
types. These cameras can be considered safe for use in hazardous areas.

Cameras that are operated by a clockwork mechanism, or with direct
mechanical devices for aperture setting and film winding, are also available
and can be considered safe for use in a hazardous area.

4.3.6 Other Portable Electrical Equipment

For guidance on the use of mobile telephones and pagers (see Sections 4.8.6
and 4.8.7.).

Any other electrical or electronic equipment of non-approved type, whether
mains or battery powered, must not be active, switched on or used within
hazardous areas. This includes, but should not be limited to, radios,
calculators, photographic equipment, laptop computers, handheld computers
and any other portable equipment that is electrically powered but not approved
for operation in hazardous areas.
