Two sidy-by-side mock dorms were set ablaze this week at Gallaudet University. One dorm room had a sprinkler and one did not. Livingston Fire Protection hoped to show the value of having a sprinkler in living quarters. However, not everything went as planned. While the sprinkler helped slow the fire in one room, the fire on the unsprinklered side melted a plastic barrier. It dripped on the three firefighters who were extinguishing the fire and set them on fire. No one was injured and all the fires were doused in a little more than 30 seconds.
