290.This paragraph exempts various categories of public servants listed at sub-paragraph (3) from requiring an air weapon certificate. This exemption relates to members of the police or armed forces who may be required to use or take possession of air weapons in connection with their duties (for example, a police constable seizing an air weapon, or a police forensic examiner testing its muzzle energy). This exemption only applies while the individual is carrying out their role as a public servant, and only when they are required to handle an air weapon in the fulfilment of their duties.
