CAMPBELLSVILLE, KY &#8211 Two firefighters were injured while using their fire truck ladder to help a college marching band take part in an ice bucket challenge, the school’s president said Thursday.

Campbellsville University asked the local fire department to help spray its Tiger marching band with cold water on one of the school’s athletic practice fields, president Michael Carter told WHAS-TV (http://bit.ly/1nfKGZ6).

The fire truck’s ladder either touched a power line or came too close to it, said Andrew Melnykovich, a spokesman for the state Public Service Commission. The ladder wouldn’t have to strike the line to cause a reaction because it carried such a high voltage of electricity, he said.

At least two, and perhaps three, firefighters were injured after the challenge, which raises awareness for ALS, the school president said. No students were hurt.

“A number of our students, of course, the entire marching band, witnessed the event and so we’re concerned about them and the tragedy of this accident,” Carter said.

Power was knocked out for about an hour to 4,500 customers in the area, including the school, said Natasha Collins, a spokeswoman for Kentucky Utilities, which owns the line. The PSC will investigate whether the power line had the correct clearance from the ground, trees and structures, Melnykovich said.

The ice bucket challenge has been sweeping social media websites. The ALS Association said it has raised more than $41 million.

Campbellsville University, a private college, says it is a Christian institution that has about 3,600 students, according to its website. A prayer vigil was to be held on campus Thursday night.
