In all, 90 percent of The American Red Cross is made up of volunteers. Dozens came together on Friday for a shelter simulation.

The Freeman Coliseum Expo Hall turned into a shelter for the day as volunteers set up cots, a feed station, and hung up posters, just as they would if they were taking over a facility in a disaster area.

"They've practiced and they're ready," said Henry Van de Putte, executive director of the American Red Cross.

The volunteers completed hours of training in the classroom and put their skills to the test. They had to work as a team to figure out how to overcome obstacles and make decisions.

Marco Banda, who's volunteered with the American Red Cross for 15 years, helped set up a shelter in February when tornadoes struck San Antonio.

"We kept it open for three nights," Banda said. "We responded and helped people who needed it."

Banda said that it's this type of training that is vital to moving quickly and helping others.
