General Information: Special Packing Regulations For Certain Articles, contd.

inner as well as of the outer container shall be packed in such a way as to
prevent any movement. Special provision, such as drying by freezing
and packing in ice, shall be made to ensure the preservation of substances
sensitive to high temperatures. Air transmission, which entails changes
of atmospheric pressure, makes it necessary, if the substances are packed
in scaled phials or well-stoppered bottles, that these containers be
strong enough to withstand variations in pressure. The outer container,
as well as the outer wrapping of the item, shall be furnished, on the side
which bears the addresses of the laboratories sending and receiving it,
with a VIOLET coloured label with the text and symbol shown above.
Radio-active Substances: Must be sent only by duly authorised senders and
their exchange is restricted to countries which admit such items. They must be
sent by registered letter and by air mail. The contents and make up of these items
must comply with the regulations of the International Atomic Energy Agency
and are admitted subject to the prior consent of the Competent Authority in this
country. They must be provided with a special white label bearing the words
“Radioactive materials” (Matieres radioactives) as well as the name and address
of the sender on the outside of the wrapper and inside the item; and a re­
quest in bold letters for the return of the item in case of non-de-livery. See
also page 59.
Gramophone Records:
1. Shellac: These should be enclosed in their envelopes and sorted in sets
according to size. Each set should be cross-tied to form a compact bundle. The
bundle or bundles should then be firmly embedded in sufficient soft packing
material in a rigid box of wood (or of stout fibreboard, preferably with a lid
extending about two-thirds of the depth of the box) of sufficient size to permit at
least one inch of packing above, below and around the records.
2. Long Playing (Plastic): These should be enclosed in their envelopes and
sorted in sets according to size. Each set should be placed between corrugated
cardboard fillers in a separate rigid box of stout cardboard or fibreboard (prefer­
ably with a lid extending about two-thirds of the depth of the box so that the
records cannot move about in the box. Where it is desired to send more than one
size of record in the same box, any empty spaces around the edges of the smaller
records should be filled with soft packing.
Hats, Millinery: These and similar articles should be packed in rigid boxes of
wood or other material, or in stout leatherboard or fibreboard boxes with lids
extending at least two-thirds of the depth of the box, or in strong cardboard
boxes protected externally at the top, bottom and sides by light cross-bars of
wood consisting of two rectangular frames placed at right angles to one another
and fastened together where they cross the top and bottom. If a square box
is used the corners should be strengthened by light wooden uprights firmly
fastened to the inside of the box. The contents should be surrounded in the box
with sufficient crumpled tissue paper or other suitable soft packing to prevent
movement. Strawboard boxes are unsuitable.
Liquids: These may be sent in tins or bottles. The tins or bottles must be
securely sealed. Tins containing a pint or more should be enclosed in fibreboard
or wooden boxes or wicker cases. Bottles should be wrapped separately, special
attention being paid to the packing around the shoulders. The bottle or bottles
should be packed securely in a rigid box of fibreboard, wood or metal, or if in
small packets sent by parcel post, in strong corrugated cardboard; in either case
with plenty of soft packing between the bottle or bottles and the top, bottom and
the sides of the box. Liquids sent by letter or sample post must be in firmly
sealed containers with a packing of sawdust or some other absorbent substance
in sufficient quantity to absorb all the liquid contents in the event of breakage, and
the whole contained in a box open at one end only with a tightly fitted lid.
