🔍 Key Concepts

• Function and hazards of compressed air receivers in an engine room • Effects of moisture (condensate) inside air systems • Purpose of safety/relief valves versus routine maintenance tasks

💭 Think About

• Which problem is most likely to occur naturally whenever air is compressed and then cooled in a receiver? • Among the options, which task must be done routinely and frequently to prevent internal corrosion and water carryover into the air system? • Which tasks listed would normally be done periodically or automatically, rather than needing constant, hands-on attention by the watchstander?

✅ Before You Answer

• Distinguish between safety devices (like relief valves) and routine housekeeping tasks (like cleaning). • Remember that condensation forms in air receivers as compressed air cools—what must be done about that? • Ask: which choice is both simple to perform often and directly addresses a common byproduct of compression?
