(Hospers, Iowa) – Officials with the northwest Iowa city of Hospers, posted to social media earlier this week, asking community members to “Please keep our Hospers Fire & EMS volunteers and families in your thoughts and prayers, following a training exercise” Monday night, during which two Hospers firefighters were injured. Officials were conducting a live burn simulation when the fire flashed over, leading to the injuries.

One of the firefighters – identified in a fundraising post as Phil Zeutenhorst- was reported to be in a burn unit in Lincoln, Nebraska, for treatment of his injuries. The second firefighter suffered minor burns. The number of firefighters who participated in the exercise is unclear.

The social media post from the City of Hospers said “We are all so thankful for these men and women from our town and all area volunteer Fire & EMS departments. Every time their pagers go off, they leave their families and loved ones to go and try to save someone else’s life or home. This Thanksgiving, may we all pray for their safety and recovery—both physical and mental. May we remember to appreciate all that they give.”

The incident is still under investigation.
