The Chemicals (Hazard Information and Packaging) Regulations 1993

Packaging of substances or preparations dangerous for carriage or supply

8.  The supplier of a substance or preparation which is dangerous for supply and the consignor of a substance which is dangerous for carriage shall not supply or consign (whether as principal or agent for another) for carriage, as the case may be, any such substance or preparation unless it is in a package which is suitable for that purpose, and in particular, unless—

(a) the receptacle containing the substance or preparation and any associated packaging, are designed, constructed, maintained and closed so as to prevent any of the contents of the receptacle from escaping when subjected to the stresses and strains of normal handling, except that this sub-paragraph shall not prevent the fitting of a suitable safety device;

(b) the receptacle and any associated packaging, in so far as they are likely to come into contact with the substance or preparation, are made of materials which are neither liable to be adversely affected by that substance nor liable in conjunction with that substance to form any other substance which is itself a risk to the health or safety of any person; and

(c) where the receptacle is fitted with a replaceable closure, that closure is designed so that the receptacle can be repeatedly re-closed without its contents escaping.
