Emergency Communication Systems in the Performing Arts Venue: Protocols for Every Scenario
In a theater emergency, communication determines outcomes. A well-executed evacuation is the product of clear communication through reliable systems operated by trained personnel. An emergency that becomes a tragedy often does so because someone did not know what was happening, could not reach who they needed to reach, or could not make the audience understand what to do. Building and maintaining emergency communication competency is a core technical responsibility.
Emergency Communication System Components
The performing arts venue emergency communication system typically consists of multiple integrated and independent components:
- Public address (PA) system: the primary means of communicating with audiences and building occupants. Must be audible in all occupied spaces including restrooms, lobbies, and backstage areas.
- Fire alarm voice evacuation system (NFPA 72 Chapter 24): in modern assembly occupancies, the fire alarm system often includes a voice evacuation capability that generates automatic announcement and allows staff to make live announcements over the fire alarm speaker network.
- Headset intercom system: communications between technical staff stations during normal operations and emergencies.
- Radio communications: portable two-way radios for staff mobility. Battery life and channel discipline are critical.
- Telephone: landline backup in areas where radio and cell coverage may be inadequate.
- Cellular: primary communication for most modern operations, but subject to network congestion during large-scale emergencies.
NFPA 72 Voice and Alarm Communications Systems
NFPA 72 (National Fire Alarm and Signaling Code) Chapter 24 governs emergency communications systems. For assembly occupancies, voice intelligibility is a requirement: announcements must be understandable, not just audible. System testing must verify intelligibility, not just sound pressure level. Backup power (minimum 24 hours of standby, plus sufficient capacity to operate the system in alarm for a minimum duration) is required.
Staff override capability (the ability for a staff member to make a live announcement through the fire alarm speaker system) is an important feature that allows for flexibility in emergency messaging. However, overriding the automatic evacuation announcement during an actual fire alarm must be done only by trained, authorized personnel who are certain that the override is appropriate.
Pre-Written Emergency Scripts
One of the most important preparations for emergency communication is writing the scripts in advance. Under stress, people default to what they have practiced. A trained stage manager or house manager reading a prepared script will deliver a calmer, more complete, and more effective announcement than one improvising under pressure.
Scripts should be prepared for:
- Fire: immediate evacuation message, exit directions, assembly point.
- Medical emergency without evacuation: message directing audience to remain seated, calling for medical personnel, requesting that aisles be kept clear for EMS.
- Bomb threat evacuation: calm evacuation message without reference to the specific nature of the threat.
- Shelter-in-place (severe weather, active threat): message directing audience to specific interior sheltering areas.
- General emergency evacuation (reason unknown): neutral evacuation message.
- All-clear message after false alarm or resolved incident.
Scripts must be kept current, located at every PA system control point, and reviewed annually.
Role Assignments for Communication During Emergencies
Each communication function during an emergency must be pre-assigned to a specific role. Typical assignments:
- 911 call: one designated person. Multiple callers to 911 simultaneously create confusion. Designate a backup.
- PA announcement: typically the house manager for front-of-house, or the stage manager for productions in progress.
- Backstage communication: stage manager coordinates with crew via headset and radio.
- Fire alarm panel liaison: the person who communicates with the fire alarm monitoring station.
- Law enforcement/EMS liaison: a designated staff member meets responders at the building entrance and provides situational information.
Medical Emergency Communication
When calling 911 for a medical emergency, communicate: the exact address of the venue (including building name, street address, city, and if applicable, suite or specific entrance), the nature of the emergency (cardiac arrest, fall injury, chemical exposure), the patient’s approximate age and condition, and the phone number the caller is calling from. Then stay on the line until the dispatcher releases you.
Designate one person to meet EMS at the building entrance and escort them directly to the patient. Announce to the audience that medical staff are needed if CPR-trained audience members may be an asset, but do so without creating panic.
Bomb Threat Communication
When a bomb threat is received by phone, a specific set of actions must occur:
- Attempt to keep the caller on the line as long as possible.
- Write down every word the caller says, verbatim.
- Note voice characteristics: male or female, approximate age, accent, speech patterns, emotional state.
- Note background sounds: traffic, music, other voices, mechanical sounds.
- After the caller hangs up, call 911 immediately.
- Do not announce the bomb threat over the PA. Use neutral evacuation language.
- Notify management simultaneously with 911 if possible.
Weather Emergencies
Severe weather requires a shelter-in-place decision. Tornadoes and severe straight-line winds require movement to interior below-grade spaces or interior first-floor rooms away from windows. The National Weather Service issues Tornado Warnings for specific areas: monitor NWS alerts via dedicated weather radio or a NWS-enabled alert system. When a tornado warning covers the venue’s location, shelter-in-place procedures should activate before the audience is aware of the threat.
Power Outage Communication
Power outages in theaters can be caused by external grid failure, overloaded circuits, or electrical equipment failure. Communication during a power outage requires: battery-backed PA and emergency lighting (required by NFPA 101 and NFPA 72), battery-powered radios for staff, pre-positioned flashlights at technical staff stations, and a protocol for communicating outage duration and audience direction to the house.
Emergency generator systems must be tested at least monthly under load. The test must verify that the generator starts automatically and that emergency lighting and the fire alarm system are powered within 10 seconds of main power loss, as required by NFPA 110 (Standard for Emergency and Standby Power Systems).
Key Takeaways
- NFPA 72 governs fire alarm voice evacuation systems. Intelligibility (not just volume) is a requirement.
- Pre-written emergency scripts for multiple scenario types should be at every PA control point.
- Role assignments for 911, PA announcements, and EMS liaison must be predetermined and trained.
- Medical emergency 911 calls require: exact address, nature of emergency, patient condition, callback number.
- Bomb threats require recording every word and calling 911. Neutral language in any PA evacuation announcement.
- Emergency generator systems must be tested monthly under load.
