Receptacles
26. Where explosives are brought into a harbour or harbour area from inland in a receptacle, the consignor of those explosives shall ensure that—
(a)the receptacle is designed, constructed, maintained and closed so as to prevent any of the contents escaping when subjected to the stresses and strains of normal handling or transport except that this shall not prevent the fitting of a suitable safety device;
(b)the receptacle and any fastenings are, in so far as they are likely to come into contact with the explosives, made of materials which are neither liable to be adversely affected by the explosives nor liable in conjunction with the explosives to form any other substance which is itself a risk to health or safety, and
(c)the receptacle is correctly filled.
