Police, firefighters and Columbia Valley Fruit employees got hands-on training at the Union Gap warehouse Thursday morning.
The group responded to a simulated release of ammonia. These types of drills happen every couple of years at the warehouse.
A Union Gap firefighter said this kind of training is important.
"The more we can train like we're going to respond, that's going to help us to be able to respond in a more effective manner," said Union Gap Acting Fire Capt. Tyler Quantrille.
No hazardous substances were actually used during this drill.
