In what might be the only good news to come out of the massive explosion at a Chinese port late Wednesday, a lone firefighter was found alive after 32 hours of being classified as “missing” by Chinese authorities.

The 19-year-old firefighter, Zhou Ti, was quickly rushed to a local hospital where it was reported he has significant injuries to his face, chest and feet.  Fire officials said that they are continuing to search for other missing fire personnel.

“Forces from all sides are searching for the (remaining) missing firefighters,” Tianjin Fire Department head Zhou Tian said at a news conference Friday, according to The Associated Press.

Chinese government officials confirmed that 56 people have died because of the explosion including 21 firefighters.  Over 700 remain hospitalized because of blast related injuries.

Western officials are now asking if the firefighters contributed to the intensity of the explosions because many of the chemicals reportedly stored at the site react with water to form explosive compounds.

David Leggett, a chemical safety expert, told Reuters that calcium carbide reacts with water to form acetylene, a highly explosive gas.  That could have ignited ammonium nitrate that was stored at the facility. (By comparison, ammonium nitrate and acetylene were used by terrorist Timothy McVeigh in the Oklahoma City bombing.)

“In my mind, the presence of ammonium nitrate makes it easier to explain the level of devastation,” he told the news agency.
