LANGLEY, S.C.-More than 100 emergency workers came together Saturday to rehearse what to do incase of a deadly chemical accident.

Fire emergency crews rushed into the CYTEC Industries chemical plant to put out a fire started by leaking chemicals as wounded employees were carried out—it's a scary scenario, but it's only a practice drill.

"It certainly could happen," said Aiken County Emergency Management Coordinator, David Ruth. "We do this type of situation every couple years so we can look at different scenarios and train. A lot of people had to take part to make this happen."

Fire crews shot thousands of gallons of water on the chemical plant to douse the imaginary fire. More than 16 different South Carolina departments and agencies rehearsed the chemical scenario.

"This will really help us to contain releases fires, and to deal with the local emergency planning committee around here," said CYTEC Site Manager, Brett Giles.

A lot of effort went into the exercise, but as emergency responders will tell you, you can never be too prepared for when something does go wrong.

Four years ago, something did go wrong in Graniteville. A train carrying hazardous chemicals collided with another train, releasing a cloud of toxic Chlorine gas over the community. Nine people were killed and more than 250 were taken to the hospital and treated for chlorine exposure.

"What we try and do here is to prevent things like that from happening,” said Giles. “We have strong safety procedures to keep chemicals contained. If they do get released, we try to minimize what we can before it gets released out to the community."

The training exercise was held in Langley, South Carolina. Organizers say they informed the public in advance to prevent any panic.
