North Hollywood, Calif. — An accidental release of sulfuric acid in a North Hollywood high school chemistry lab Monday June 11 caused a temporary campus evacuation and led to four persons being taken to the hospital to be checked over, according to the Los Angeles Fire Department. The release occurred at East Valley High School when a teacher reportedly mistook sulfuric acid for nitric acid while performing an experiment for 45 students in the class. The teacher immediately closed the container, placed it under a ventilation hood in the classroom, and moved the students from the room. Officials said there was no fire, explosion, or obvious injuries, but the school was evacuated and students assembled on the athletic field. The 45 students and teacher in the chemistry lab were individually examined at the scene by fire department responders and an emergency physician who serves as the fire department medical director. Two adults and two students with minor medical complaints were taken to an area hospital by ambulance for further evaluation.
