🔍 Key Concepts

• Standard lifeline tug signals used during tank entry or diving operations • The specific signal used for "take up slack" versus signals for "I am all right" or "haul me up" • Importance of clear pre-arranged communication between the person in the tank and the tender topside

💭 Think About

• Think about which signal would reasonably be a small adjustment, not a full recovery or emergency pull • Recall the typical progression: fewer tugs often mean routine or status messages, more tugs are reserved for more urgent or significant actions • Consider which signal should be clearly different from the signal for "emergency" or "pull me up immediately"

✅ Before You Answer

• Make sure you are NOT mixing up "take up slack" with "haul me up" or "help/emergency" • Confirm from your study materials the full set of lifeline signals (all meanings for 1, 2, 3, and 4 tugs) • Verify that the signal you choose would make sense as a minor adjustment rather than a major action by the topside tender
