Any additional amount of packing material necessary completely to fill the case when the packing material is well pressed down must consist of whiting or other non-organic material, For Nitric Acid above 70% w/w or 1.420 S.G. the absorbent and protective packing materjal must not consist of unapproved organic material, but may consist of whiting, whiting kierelguhr, kieselguhr or an intimate mixture of coarse exfoliated vermicu- lite and whiting consisting of 70%-80% whiting by weight and 20%-30% exfoliated vermiculite by weight or other substance approved by the Ministry or Authority.

Regulations for packing Nitric Acid exceeding 8% w/w or 1.045 S.G. in glass or earthenware containers, in cases. Cases conizining Nitric Acid in glass or earthenware containers must, as regards packing (1), conform to the following requirements-

(1) When two or more containers of a diameter exceeding 34 inches (90 mm.) are packed in a case, the case must contain an internal partition or partitions, with the object of maintaining the position of each such container in relation to each other such container in the case.

(2) The packing material surrounding containers must be well pressed down so as to prevent movement of the containers within the case and to keep each container from contact with each other container.

(3) If there is a risk of the throber (of which the case is made) shrinking through drying, steps must be taken

to avoid loss of packing material: such steps may include the lining of the case with strong paper.
