MILLBURN, NJ - Burnt quiches were the source of smoke that activated the fire alarm system at Millburn High School today, causing an evacuation of about 1,500 staff and students.

A fire drill had been conducted earlier in the morning, therefore when the fire alarm went off for the second time at around 1:08 P.M., many had already assumed the second alarm to be "the real thing".

The entire building was evacuated for about 25 minutes while the Millburn Fire Department responded to the alarm and evaluated the situation. In an email today, MHS Principal Dr. William Miron noted that "Quiche was burnt causing excessive smoke - no true 'fire'", providing a feeling of relief for some.

Students returned to classrooms safely by 1:30 P.M. and continued with the remainder of the day's classes.
