Paragraphs 2 and 3 do not exclude a person's civil liability for loss or damage, or his criminal liability, resulting from his negligence in doing any thing.

Paragraphs 2 and 3 do not authorise a person to do anything otherwise than for the purpose of the standard or urgent authorisation that is in force.

In a case where a standard authorisation is in force, paragraphs 2 and 3 do not authorise a person to do anything which does not comply with the conditions (if any) included in the authorisation.
