HUDSON, Ohio -- The conditions have been upgraded for two people who were injured during an accident involving an experiment in a chemistry class at Western Reserve Academy, NewsChannel5 reported.

One of the students most seriously injured may be in the intensive care unit for the next month.

Three students along with their teacher, Julie Pratt, 37, remain in the hospital after the accident on Monday afternoon.

Pratt's condition has been upgraded from fair to good and a 15-year-old student's condition has also been upgraded from serious to fair. Pratt's son and another student remain in serious condition.

Pratt's 11-year-old son, who is a sixth-grader in Hudson, was sick, but went to school with his mother on Monday.

In all, eight students were injured. Three students were treated at the school's health center.

The students, who were primarily seated in the front row of the class, suffered burns to their upper torso, face and hands, WEWS reported.

Officials say the students, who are at the Akron Children Hospital burn unit, are in "good spirits" and they are also receiving psychological counseling.

Calais Weber, wrapped in bandages and her head shaved, said from the hospital that a janitor also helped put out the fire. Gary Fitts "just happened to be walking by and grabbed the fire extinguisher," Weber said.

Weber, 15, suffered burns on about half her body, including her face and hands. Cecelia Chen, 15, was burned on her hands and torso. Sam Pratt, 11, whose mother the chemistry teacher, suffered burns on his face and upper torso. One student was treated and released.

Students come to the school from all over the country and world, WEWS reported.

"They (students) want information. They want to hear about their friends. They also want to visit their friends, if possible," Burner said. "We're waiting until (Tuesday) when we can learn more about the process."

Students "were instrumental in helping each other douse the flames," said John Haile, dean of academics. "They also stopped, dropped and rolled."

The victims then hurried to showers in the back of the lab, there specifically for such accidents.

The fire occurred while students worked with methanol during an 11th-grade comprehensive chemistry class. Furniture, textbooks, book bags and the lab table were damaged.

The school has 401 students, including 273 who live on the campus about 30 miles southeast of Cleveland.
