How do the UK HSE information sheet on firearms and weapons (ETIS20 rev3) and the US Safety Committee bulletins differ on live ammunition, replica substitution, police notification and edged weapons, and what should an agent flag for a production crossing both?

HSE's ETIS20(rev3, first published 11/23) treats firearm and weapon safety as an employer risk-assessment duty under UK health and safety law. It says live ammunition should never be taken to set, then later says it should never be available on site except for safety reasons such as filming with animals; it requires police notification when a weapon could be seen or heard in a public place and recommends replicas and blunted blades. US Bulletin #2 allows live ammunition only in narrow controlled exceptions. Both stress competent armourer/Property Master control, briefings and least-hazardous weapon choice (HSE: training, competence and knowledge of the person in charge); bulletin #30 adds 'use simulated or dummy props whenever possible'. Curator qualifications: All statements verify. The UK/US comparison is fair, and the producer correctly marks the exceptions as different in kind. Reading note on the ETIS20 'internal tension': the first sentence is scoped to live ammunition taken to set 'for use in filming activities', while the second allows availability on site for safety reasons (e.g. when filming with animals). Read together they are consistent: no live ammunition for filming, a narrow non-filming safety exception. Present this as a scoped exception, not an inconsistency. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
