What is ice-shrugging best described as?

Ice-shrugging is a technique specifically designed to manage and alleviate ice accumulation on aerial devices such as ladders or platforms. The method involves the gradual extension and retraction of the aerial device, which helps to dislodge ice that may have built up during colder weather conditions. This careful movement allows for the release of ice without causing damage to the equipment or posing a safety risk.

The other methods mentioned, such as applying salt, using hot water, or waiting for natural melting, do not effectively address the immediate safety and operational concerns that often arise when ice forms on fire apparatus. While applying salt can be a common method for melting ice on walkways or roads, and hot water might wash away ice, these options can lead to different risks or are not practical for aerial devices in an emergency situation. Therefore, extending and retracting the aerial device is the most effective and commonly accepted practice for dealing with ice in this context.
