Which of the following is NOT a method of dry lay-up?

• A. Heated air lay-up
• B. Desiccant
• C. Water lay-up
• D. Chemical lay-up

Answer: (C)

The correct identification of water lay-up as not being a method of dry lay-up stems from the definition and purpose of the various lay-up methods typically used in equipment preservation, particularly for machinery and systems that can be affected by corrosion. Dry lay-up methods are primarily designed to protect equipment by keeping it free from moisture, which can lead to rust and other forms of degradation. Heated air lay-up involves circulating warm, dry air through the equipment to remove moisture. Desiccant lay-up uses materials that absorb moisture from the air, providing an environment where humidity is controlled. Chemical lay-up refers to the use of specific chemicals to inhibit corrosion while keeping the system dry. In contrast, water lay-up actually involves the application or retention of water within the system, which exposes the equipment to moisture, contradicting the principles of dry lay-up. This method is not used for dry preservation, as it could lead to corrosion and other issues, which makes it distinct from the other options that focus on moisture control.
