Updated 4:16 p.m.: The University of Maryland has reopened the chemistry building, according to a Department of Public Safety alert at 4:07 p.m.
Update 3:56 p.m.: Prince George's County Fire Department spokesman Mark Brady also confirmed at the press conference that the two substances the students were experimenting with were nitric acid and sulfuric acid, although the original statement said nitrogen and sulfuric acid were involved.
In all, there were 11 students in the lab at the time of the explosion, although only four were decontaminated, and two were injured with first- and second-degree burns and superficial lacerations.
Update 3:29 p.m.: The explosion occurred when two students conducting an experiment poured two substances into a waste basket, which reacted with a third substance, Prince George's County Fire Department spokesman Mark Brady said at a press conference Monday afternoon.
He said that it is not uncommon for the department to respond to incidents at the chemistry building. It is not typical, however, the students are injured in such incidents, Brady said.
He said that the chemistry building has been turned over to the University of Maryland, and it is now up to the university when to reopen.
Brady also tweeted after the press conference that the "products" have been neutralized by the hazmat team, and that there was significant damage to the hood system.
Update 3:15 p.m.: The chemical explosion occurred when nitrogen and sulfur acid were mixed in an experiment, according to a statement from the Prince George's County Fire Department.
