After ice-arena alarm, Waterville Valley board orders review of evacuation and alarm connections

Town public-safety staff reported a recent incident at the ice arena in which ammonia-system venting and a coincident power outage triggered alarms and smoke-like venting. The fire chief said vendor checks confirmed there was no ammonia leak and that the alarm was a faulty trip — but the event revealed gaps in communications and alerting for Town Square.

The chief said the facility’s ammonia alarm did not dial out to dispatch as expected and described a visible blue exterior alarm light that alerted responders when they arrived. Board members and staff discussed whether the ammonia alarm should be tied into the main fire-alarm dial-out or whether an additional audible/visible alarm should be installed in Town Square to make the hazard obvious to visitors and staff in adjacent buildings.

“One of the problems is nuisance alarms create complacency and complacency kills,” the fire chief said, urging that any change help reduce false positives while ensuring people evacuate for truly dangerous events. A board member recommended adding a secondary audible alarm and improving signage and muster-area instructions so visitors and staff know where to gather after an alarm.

Staff committed to reviewing the Town Square emergency-response plan, verifying that the ammonia alarm is connected into dispatch zones, and exploring options for reverse-9-1-1 or other mass-notification systems for residents and visitors if an off-site plume required wider notice.

Next steps: staff will follow up with the arena’s alarm vendor to connect the ammonia zone to the main fire/dispatch system, inspect visibility of the exterior alarm, and schedule a full review of evacuation procedures for Town Square.
