Stadiums and arenas: voice alarm evidence the Safety Advisory Group can check

What brings a stadium safety officer to this page?

A condition on the safety certificate, or a question at the SAG, that asks for readings rather than a certificate. A fault during an event. A retender where the reports list visits but not measurements. And Martyn's Law: a ground of 800 or more falls in the enhanced tier of the Terrorism (Protection of Premises) Act 2025, expected to commence in spring 2027 with no date set (SIA update, 11 September 2026). What the Act asks of venues.

Which standards apply to a stadium PAVA?

Three documents, in a chain.

The Green Guide (Sports Grounds Safety Authority, 6th edition, 2018) has no statutory force of its own. Its recommendations bind a ground where the safety certificate issued under the Safety of Sports Grounds Act 1975 makes them conditions, as local authorities commonly do. Where the PA forms part of the fire warning system, the Guide's own word is that it "requires full compliance with the relevant parts" of BS 7827 (Green Guide 16.18(d)).

BS 7827:2019 is the venue-scale code of practice. It recommends a risk assessment dividing the ground into voice-alarm zones and emergency-sound-system zones, each then following BS 5839-8:2023 or BS EN 50849:2017 (BS 7827:2019, Clause 4.1). For sports grounds it recommends 3 h of standby power with a 3 h duty cycle, with or without a generator, because the duty cycle follows the length of the event including getting the crowd in and out (Clause 15, Table 2). That is a survival window for keeping a crowd informed, not three hours of broadcasting, and the batteries are sized to it.

BS 5839-8:2023 governs the voice-alarm zones: servicing at intervals not exceeding six months (BS 5839-8:2023, Clause 40.1), annual activities including every loudspeaker circuit impedance measured and compared with the previous year's (Clause 40.2), and a certificate on completion (Clause 40.4). All three documents recommend rather than require; a departure has to be justified in writing.

What does a maintenance visit have to prove at a sports ground?

The Green Guide recommends an annual commissioning certificate, two inspections a year and checks before each event (16.18(g)). Each inspection covers performance on power failure and on auxiliary power, loudspeaker performance, loudspeaker-circuit fault monitoring, and high-level loudspeaker fixings including any secondary fixings, and produces a certificate with a report of findings for the local authority where a safety certificate is in force.

The report serves all three readers at once, and every finding carries the clause it falls short of, its risk level and a recommended action. A certificate records that a visit happened. The readings record the condition of the system. It's worth asking for the readings.

On Recommended and Comprehensive, every loudspeaker circuit is measured and compared with the year before, so drift is caught before it becomes a fault. Repairs are quoted separately, so nothing is gained by missing a fault. Essential is the functional-checks level, measuring up to 35 % of circuits a year with faulty circuits first, and is rarely the right level for a licensed ground. Essential does not meet the recommendations of BS 5839-8:2023.

Where this has been done

Fulham Football Club. Emergency sound and PA systems at Craven Cottage, a Premier League venue where crowd safety and zoned evacuation are critical. The complete stadium sound system is maintained by ProAudium, so the club can host tens of thousands of supporters safely on match days and run conferences and corporate events on non-match days.

Which service does a stadium need first?

Scheduled maintenance tied to the certificate cycle, each visit building on the record of the last: see the three maintenance levels. A pre-contract assessment against the Green Guide is consultancy.
