What is NOT a concern associated with ice resurfacers?

Oxygen release is not a concern associated with ice resurfacers as they operate primarily by resurfacing the ice with a thin layer of water that freezes to create a smooth skating surface. This process does not involve any operations or materials that would release oxygen into the environment.

In contrast, energy consumption, water usage, and maintenance costs are significant considerations for facilities using ice resurfacers. Ice resurfacers require energy to operate, which can lead to high utility costs and impact overall facility sustainability. Water usage is another critical factor, given the need to maintain a proper ice surface; facilities must manage this resource carefully to avoid waste and ensure the quality of the ice. Additionally, upkeep and repair of the resurfacing equipment can incur substantial maintenance costs, making these three elements important concerns for facility managers overseeing ice operations.
