So far as reasonably practicable
The standard the Act uses for enhanced measures — proportionate to the venue, its risks and what is feasible, not a fixed checklist.
Enhanced-tier measures must be put in place 'so far as reasonably practicable'. This is a proportionality test familiar from health and safety law: what is reasonable balances the risk against the time, cost and effort of addressing it.
It means there is no single mandated kit list. What is reasonably practicable for a 1,000-capacity venue differs from a 5,000-capacity one, and the responsible person makes that judgement.
Who it affects: Enhanced-tier responsible persons deciding what measures to put in place.
