The IndyCar Series will make a safety modification for this weekend's Iowa race after determining that a procedural error led to a malfunctioning fire hose at Texas. As a result of what happened this month at Texas, the series will change the hoses placed on all safety trucks beginning this weekend. Mike Yates, the series' track safety manager, said the hose was not packed properly into the safety truck after passing its regular prerace test. Yates also said it has been determined that the canisters, which were used to put out the fire in Simona de Silvestro's car, are more efficient in extinguishing fires. Yates said that would be reviewed with the league's safety team before Sunday's race. http://sports.espn.go.com/rpm/racing/indycar/news/story?id=5294273
