🔍 Key Concepts

• Safe watchkeeping practices for boilers • Difference between routine visual checks each watch vs. periodic maintenance tasks • Risks associated with boiler leaks compared to adjustment/cleaning work while in operation

💭 Think About

• Which of these tasks can be safely and reasonably done every watch while the boiler is firing without shutting it down? • Which options sound more like scheduled maintenance (daily/weekly/yard period) instead of a normal watch-standing duty? • What condition, if developing during a watch, would require immediate attention to prevent a fire, explosion, or machinery damage?

✅ Before You Answer

• Identify which options would normally require the boiler to be secured, cooled, or isolated before doing the work. • Ask yourself which action is a non‑intrusive observation versus hands‑on interference with safety devices or fuel components. • Confirm which action aligns with standard practice of continuous monitoring for abnormal conditions on a running boiler.
