Which remote training ground environment used for live-fire evolutions and ventilation training must include a complete safety assessment per the AHJ before training can begin?

The correct answer is acquired structures. Acquired structures, which may include buildings that are no longer in use or those that have been donated for training purposes, require a thorough safety assessment by the Authority Having Jurisdiction (AHJ) before any training can commence. This safety assessment ensures that the structures are suitable for live-fire evolutions and ventilation training, addressing potential hazards that could arise during such exercises.

The need for a safety assessment is crucial in these environments because acquired structures may have unknown variables related to their condition, hazardous materials, or structural integrity. Proper evaluation helps mitigate risks to both the trainees and the surrounding community.

In contrast, while parking garages, grain elevators/silos, and military or government-owned reservations may have their own safety protocols, they often involve established operational guidelines that differ from acquired structures requiring initial assessment. These environments may already be set up for specific training without the same level of scrutiny as structures being repurposed for training.
