How are the sides of the rink typically referred to?

The sides of the rink are typically referred to as dasher boards. These boards serve multiple purposes including keeping the puck in play and protecting players from leaving the rink area during physical play. Dasher boards are made from materials that can absorb impacts, thereby also providing a level of safety for both players and spectators. They are an essential component of the design of an ice rink, ensuring that the game proceeds smoothly while also providing safety features.

The mention of the other terms, such as ice barriers or surrounding boards, may reflect similar concepts, but "dasher boards" is the official terminology widely accepted in the context of ice hockey and rink facilities. Safety walls, while important, typically refer to elements that might be outside the rink area and focus more on fan safety.
