At what wind speed must deicing vehicle booms be retracted for safety?

The correct answer signifies that safety guidelines dictate deicing vehicle booms should be retracted at a wind speed of 44 mph. This threshold has been established based on potential hazards associated with high winds, such as decreased stability of the deicing equipment and increased risk of accidents or equipment damage.

At wind speeds exceeding 44 mph, the operational safety of personnel and the effectiveness of the deicing operation can be compromised. Maintaining a controlled environment during deicing operations is critical to ensuring both the safety of ground crews and the efficiency of the deicing process. Therefore, retracting the booms at this wind speed is a proactive measure to mitigate risks associated with adverse weather conditions.
