What the Enforcement Guidance says:

Article 6 provides that, subject to certain exceptions clearly listed in the legislation, the Order will apply to all premises. Particular attention is drawn to the definition of “domestic premises” where article 31 is the provision relating to prohibition notices: it is the sole exception to the rule that the Order does not apply to domestic premises used for domestic purposes.
Article 6 disapplies the Order in relation to certain means of transport. In respect of those means not disapplied under that article, article 7(2) disapplies articles 9(2), 12, 16, 19(3) and 22(2) in relation to the use of means of transport for dangerous substances, which are covered by international and European Directives legislation, except for any means of transport which is intended for use in a potentially explosive atmosphere. In practice, this means only vehicles not used on the public highway are likely to fall within the scope of the Order (e.g. forklift trucks or “cherry-pickers” used in a warehouse).
