The original call came in as a "pull station" or manual fire alarm turned in to the fire department around 2:05 p.m..
Arriving companies then reported the leak of small containers of "ammonium hydroxide."
Additional fire crews- along with Lawrence and Douglas County 'Haz-Mat' crews were dispatched at 2:15 p.m. when a complete evacuation of students and faculity from Malott Hall- near 'Wescoe Beach-' was under way.
The leaking containers were removed from the building and fire and Haz-Mat crews undertook a "decontamination" of the areas affected.
At least one person was treated for a "minor injury" related to this incident- according to a LFD source.
