The 2,800-acre lightning-sparked Prater Fire in Sparks is now fully contained after sparking around 3 p.m. Sunday behind the Northern Nevada Medical Center. 

The blaze prompted a voluntary evacuation order for residents in the east Sparks area on Sunday. All evacuations have since been lifted.

Operations Chief Jim Reid said the blaze burned close to the Northern Nevada Medical Center but luckily, there was no damage. 

"There wasn't a lot of threat from the fire but from the smoke into the vent systems was probably the most hazardous thing to them," said Reid.

Sean Applegate, director of engineering for the Northern Nevada Medical Center, said an emergency plan was in place. Despite no evacuations being made, the hospital did prepare for all of the smoke.

"Within minutes we had mobilized our engineering team to all the floors to shut off all the fresh dampers from outside to make sure we weren't having any issues," said Applegate.

Sparks Fire crews say about 130 people are working to contain the fire. Firefighters used the Earthstone Fire burn scar in their containment efforts. By guiding the Prater Fire toward the already burned vegetation, there were less fuels for the newer fire to burn.
