The Snow and Ice control plan includes which parameter related to the timing of operations?

• A. timely commencement
• B. prompt notification
• C. approved materials
• D. removal and control

Answer: (A)

Starting snow and ice control actions at the right moment is critical to safety and efficiency. The Snow and Ice Control Plan specifies a timing parameter called timely commencement, which sets the moment to activate the plan and begin operations once predefined weather thresholds or activation criteria are met. This is the best choice because it directly governs when to mobilize crews and equipment, ensuring actions happen early enough to prevent rapid buildup and maintain safe operations on pavements and runways. Other elements address different aspects: prompt notification concerns how quickly stakeholders are alerted, approved materials define which agents may be used, and removal and control covers how snow and ice are physically removed and managed, not when to start the response.
