The intermission between periods two and three of the Yale-St. Lawrence women’s hockey game turned out to be a bit longer — and much more eventful — than expected.

More than 100 people poured out of Ingalls Rink around 5:15 p.m. on Saturday as an automated message repeatedly cautioned spectators to evacuate while a potential “fire emergency” was investigated.

The Saints trooped out to wait on their bus and firefighters quickly arrived on the scene. But the commotion turned out to be a false alarm: A Zamboni had knocked into a pipe while moving onto the ice and caused a water leak, a Yale security officer said.

Five firefighters exited the rink at 5:28 p.m., as the spectators and St. Lawrence’s squad reentered. Play resumed around 5:45 p.m.

Yale won the contest, upsetting St. Lawrence 1–0.
