🔍 Key Concepts

• Cold weather operation of steam-driven equipment on deck • Purpose of cycling mechanical equipment (keeping parts moving, preventing freezing or seizing) • Difference between continuous daily precautions and infrequent checks in freezing conditions

💭 Think About

• In freezing conditions, how quickly can standing water or condensate inside pumps and lines freeze if equipment is not moved? • Which choice best reflects a preventive routine that matches the ongoing nature of freezing risk, rather than an occasional check? • Think about what engineers and deck crews realistically do on a ship in very cold weather to ensure equipment will work instantly in an emergency.

✅ Before You Answer

• Compare which options involve regular, short‑interval action versus long gaps between actions. • Ask whether merely watching equipment while idle actually prevents ice from forming inside the pump or lines. • Consider which interval (daily, weekly, every 4 days) aligns with the phrase "when the danger of freezing exists", meaning the risk is present every day.
