What is the recommended method for de-icing an aerial device?

The recommended method for de-icing an aerial device is using high-pressure steam. This approach is advantageous because steam effectively melts ice without introducing additional moisture, which could cause refreezing or further complications with the equipment. High-pressure steam can penetrate and loosen the ice buildup, facilitating its removal while minimizing the risk of damage to the aerial device.

Using a heat gun, while it can provide heat for localized melting, may not be efficient or safe for larger areas of ice accumulation typically found on an aerial apparatus. Applying corrosive chemicals is risky as it can damage the vehicle's structure and components, leading to expensive repairs and decreased longevity of the equipment. Regular water would not be helpful in de-icing, as it can lead to further freezing and create more ice issues, rather than resolving the problem effectively. Thus, high-pressure steam emerges as the best method for safely and efficiently de-icing an aerial device.
