A bottle full of ammonia and bleach spilled onto the floor of a Vancouver high school classroom, and the fumes sickened four students and three staff members.
School officials said one student brought the bottle to class at Skyview High School and held it in front of another student. That student pushed it away, and the bottle spilled onto the floor.
"We were sitting in class and just about the end of the period the security guards came in and told us to evacuate the area and to get all of our stuff and go out the commons area," said Brandon Zink, a sophomore at the school.
The fumes started to make some of the students cough.
School staff cleared the area, and paramedics responded to treat at least four students, fire officials said.
In all, seven people were taken to Legacy Salmon Creek Hospital to be treated and were later released.
Parents were notified by a phone message alert that went out earlier in the day.
"For them to take that precaution that there was a spill and it was being taken care of, I'm pretty confident that they knew what they were doing," said Diane Neel, a parent of a student at Skyview.
Though the affected classroom was evacuated, the rest of the school is operating as normal.
A Vancouver hazmat team assessed the situation and collected any of the possible materials involved.
School officials said the student responsible was expelled from school on Thursday afternoon.
The 14-year-old freshman was also arrested by Clark County deputies.
Detectives said the boy was taken into custody and lodged at the Clark County Juvenile Detention Center. He is charged with two counts of assault and one count of reckless endangering.
There are no other suspects in the case, according to deputies, but the investigation is continuing.
"It's a serious incident whenever hazardous material is introduced into the school and people are exposed and injured," said Sgt. Fred Neiman with the Clark County Sheriff's Office.
