What installation can help Alaina prevent vehicle impacts on her organization's backup generator?

Bollards are short, sturdy posts designed to prevent vehicle access to certain areas while allowing pedestrians to pass. By installing bollards around the backup generator, Alaina can create a protective perimeter that safeguards the generator against potential vehicle impacts. This is crucial for maintaining the operational integrity of the generator, ensuring that it remains functional in emergencies. Bollards are effective in absorbing and deflecting impacts, thereby reducing the risk of damage caused by errant vehicles.

While barriers, fencing, and warning signs can play roles in security and safety, they do not provide the same level of impact protection as bollards. Barriers may prevent access but can be less effective than bollards in direct impact scenarios. Fencing serves to delineate property and restrict access but does not stop vehicles from crashing into sensitive areas. Warning signs can alert drivers to the presence of key infrastructure, but they do not offer physical protection. Therefore, installing bollards is the most effective solution for preventing vehicle impacts on the backup generator.
