ADA, OK -- Local first responders got to test their skills this week in emergency response training.
Mock shootings, explosions, and dealing with hazardous chemicals, are among the exercises at this weeks emergency response training at East Central University.
"If you're not trained up to know what you're doing, you could ultimately take your life or your buddys next to you," said Sergeant Chris Cummins.
Cummins, who's with the 63rd weapons of mass destruction civil support team out of Norman, says there's no such thing as too much training.
"We actually just left Durant courthouse here recently. They had a white powder scare and it's just, you never know," said Cummins.
"It's the one time that you can mess up and not have the reprecussions, because if you mess up in the real world, it's not good," said Sergeant Neal Casey.
Close to a hundred first responders from 10 different Oklahoma agencies took part in the situational exercises.
"We're going to come back for another exercise tomorrow. Could be something totally different, and then Thursday we'll kind of do a little group, kind of talk about how it went, ups and downs about it," said Casey.
EMS operations supervisor for Mercy Ada, Chris McGill, says learning to work with other first responders is important when it comes to saving lives.
"It gets us all in the same room talking to eachother, and we get to know eachother, and we build relationships, and when the real event happens, we know eachother when we show up," said McGill.
