Inside Pallas’s main-hall blackout drill

How Pallas tests its emergency lighting for a complete blackout scenario in the main hall begins with a staff-only rehearsal inside Berlin’s E-Werk, before doors open and the first set begins. The aim is not theatrical darkness. It is a controlled test of whether people can recognise escape routes, read illuminated signs and move safely when every normal light source has gone out.

The temporary festival setting makes that work more exacting than in a conventional club. Main-hall equipment shares space with stages, bars, cable routes and temporary structures, all inside a historic industrial building whose retained brick, steel and concrete cannot be altered casually. Every emergency luminaire therefore has to be positioned around the audience experience and the protected fabric of the venue.

A blackout test also sits alongside Pallas’s commitment to CO2-neutral event operations. Emergency lighting is usually modest in wattage, but it must stay available for the required period, and batteries have their own material and servicing footprint. Measuring that load, maintaining reusable power systems and documenting end-of-life handling makes the safety exercise consistent with the festival’s environmental responsibility rather than separate from it.

Australian visitors may not know the hall, but the operating logic is familiar: crews in Sydney, Melbourne, Brisbane and Adelaide often work with tagged temporary power, documented pre-shift checks and disciplined defect reporting. Many Australian electricians also know AS/NZS 2297 as a benchmark for maintained emergency lighting and exit signage, although German building and fire-safety requirements are the rules that govern a Berlin event.

Preparing the hall before power is cut

The preparation starts with a walk-through led by the venue’s authorised electrician and a safety coordinator. Production, stage management, security, accessibility and front-of-house representatives mark every exit, refuge point, fire-control position and emergency fixture on a hall plan. The test controller then confirms who may call for darkness, who can restore power and who has authority to stop the exercise.

Teams inspect each battery-backed fitting, exit sign and distribution board rather than assuming that a green indicator means the unit is healthy. They record lamp status, battery age, cable condition and the circuit feeding each fitting. At E-Werk, freestanding mounts and surface-safe cable covers are used where possible, protecting historic surfaces while avoiding trip hazards around queues and stage access.

A daytime walk-through establishes normal conditions before the lights disappear. Staff take reference readings with a calibrated light meter, photograph any dark corners and agree on a spoken warning for the simulated loss of mains. The brief separates genuine life-safety equipment from decorative architectural lighting, so a spectacular set blackout cannot be mistaken for a verified emergency response.

Creating a true loss of normal lighting

Power is isolated in a deliberate sequence after the public has left and the hall has been cleared for testing. The venue electrician switches off general lighting, house circuits, stage wash and decorative LEDs, then removes the automatic generator from the test so the lighting bus experiences a genuine loss of normal supply. Independently protected emergency circuits remain energised, which is the condition being assessed.

Residual glow can hide defects. Dimmer tails, standby LEDs, illuminated signs and equipment on uninterruptible supplies are checked for continued output, and any unwanted light is recorded. Observers stationed around the hall note whether a fitting switches on, whether an exit remains visible and whether battery-backed units hold their output. A complete blackout here means no routine lighting, not a reckless severing of the safety system.

The team also distinguishes two different failures. A transfer test examines what happens when the generator starts; the blackout scenario assumes it does not. The emergency bus must carry the load alone, while radios, meters and any monitoring computers use separate batteries. Each step is called on a dedicated channel and acknowledged before the next begins, eliminating guesswork from an otherwise confusing dark hall.

Checking routes people actually use

Once the room is dark, staff follow the routes guests would use rather than a convenient inspection loop. They travel from the main-stage area toward principal exits, through corridors, past bars and service spaces, and along any step-free route available in the building. Wardens check that signs are visible from approach angles, doors can be opened without hunting for hardware and temporary cables do not cross the escape path.

Routes are tested under different conditions, including doors held at their working angle, an exit partly obstructed by production equipment and a doorway affected by a bright neighbouring space. The exercise does not stage a panicked evacuation, which could create more risk than it reveals. Instead, staff move at a controlled pace, using torches to represent a personal light and reporting any hesitation or missed direction.

International and local audiences need more than an illuminated arrow. Australian guests may recognise the strong pictograms and transport-style exit cues from Melbourne tram stops or Sydney rail stations more readily than Berlin’s U-Bahn and S-Bahn signs, but unfamiliar language or street layout can still slow a decision. Clear icons, floor-level direction and staff positioned at decision points are therefore treated as part of the emergency-lighting result, not decoration.

Testing equipment under real conditions

Technical measurements sit beside the human walk-through. The electrician samples illumination at floor level, on exit signs and at changes in level, comparing the readings with the approved venue plan. Fittings are checked for correct aiming: a bright lamp aimed into a performer’s eyes may leave the actual escape route dark. This is especially important where truss, haze, decorative structures and stage scenery can interrupt sight lines.

Battery endurance is verified through commissioning records and witnessed discharge testing, rather than by assuming a brief blackout proves the full required runtime. During the live drill, observers time how quickly each unit establishes light, whether output sags under load and what warning appears when a battery reaches its limit. A failed fitting, faded sign or weak emergency bus is recorded as a defect with its exact location.

Protective devices and isolation points receive equal attention. A unit that stays dark because of a tripped breaker must not be mistaken for a defective lamp, while a wrongly connected fitting can mask a circuit fault. Labels at distribution boards are compared with the hall plan, spare lamps and compatible batteries are confirmed on site, and the restoration sequence is rehearsed so normal power cannot return while staff remain in the test zone.

Keeping the drill safe and observable

Timing begins when the general lighting is lost. The safety coordinator logs how long it takes for the first emergency fittings to activate, how long staff take to identify the nearest exit and whether the hall remains visibly oriented. Radio discipline is tested under the impaired conditions: callers use location and direction rather than vague references such as “over there”, and acknowledgements are short enough to avoid crowding the channel.

A guest-facing production blackout is a different exercise. Pallas may programme darkness into a set, but it is never used to imply that an evacuation is underway, and no visitor is asked to move through a sudden, unannounced loss of light. Rehearsals involving guests focus on staff communication and accessible assistance, with any sensory concerns recorded before doors open rather than discovered during a performance.

Visitors arranging travel can confirm programme details on the Pallas event tickets page, while important safety information remains part of the booking and on-site briefing. If darkness is part of a show, the stage manager tells nearby crew in advance and keeps a lit access route available. The emergency test itself occurs outside public hours, when an audience can be evacuated safely if staff spot a genuine problem.

Recording failures and energy use

Every observation becomes evidence. The log records the fixture identifier, circuit, time, measured performance, photographs and the person responsible for correction. A result is not marked as passed merely because most of the hall looks dark: one obscured sign or short-lived battery can affect the route used by dozens of people. Findings are reviewed with the electrician, safety coordinator, production lead and venue representative before the setup is approved.

The review also looks beyond compliance. Energy readings from the emergency bus show how much electricity the safety system consumes during a show, which can be included in Pallas’s carbon accounting instead of being treated as negligible. Longer-lived batteries, rechargeable site equipment and documented take-back routes reduce waste; battery stewardship is increasingly familiar to purchasers and event organisers in the Australian market.

Clear location reports also help the festival spot patterns that a single inspection may miss, such as a beam repeatedly blocked by a new scenic element. During an event, guests should alert the nearest staff member; after it, a precise observation can be sent to the Pallas contact team and matched with the drill or show log. Genuine hazards are handled immediately rather than waiting for email.

Signing off the blackout test

Sign-off follows a final sweep. The electrician confirms that every failed fitting has either been repaired, replaced or placed on an approved restriction, and that temporary equipment has been removed from routes. The safety coordinator checks staff observations, the controller reconciles the circuit log and production confirms that the restored lighting matches the pre-test state. Only then is the blackout scenario closed.

The findings feed directly into the next production brief and emergency plan. Wardens repeat any changed route, stage crews learn which fixtures are protected from power cycling, and front-of-house teams receive updated wording for an evacuation announcement. If a proposed scenic change could affect visibility, it becomes a review item before installation rather than a surprise on the night.

Before the next crew call, the venue electrician will update the main-hall lighting plan with the measured emergency-bus load and the exact location of every unresolved defect, then schedule a retest of the affected circuit.
