In case you didn't already know VASTS has to do with aerospace and what not...this was one of the questions on our discussion forum....this is exactly what it says--

Rags, tie wraps, and safety wire are examples of ______ contamination?
....there was a similar question that read:Residues, chemical outgases, and contaminated fluids are examples of this type of contamination.(and the answer was "molecular"

To find the answer to the first question, "Rags, tie wraps, and safety wire are examples of ______ contamination?" we can start by understanding what contamination means in the context of aerospace.

Contamination refers to the presence of unwanted foreign substances or particles that can affect the performance, reliability, or safety of aerospace equipment, systems, or components. These substances can come from various sources, such as external environment, manufacturing processes, or maintenance activities.

In this case, the given examples are "rags, tie wraps, and safety wire." Based on their nature, these items are commonly used tools or materials during maintenance or repair procedures. Therefore, the contamination they can introduce is likely related to physical contaminants, such as dirt, debris, or loose particles.

To determine the correct term for this type of contamination, we can look for a word that represents physical or solid contaminants. One possible answer could be "particulate" contamination, as it refers to the presence of solid particles or foreign matter in a system. Particulate contamination can have detrimental effects on the performance and reliability of aerospace equipment, especially in sensitive areas like engines or precision instruments.

Now, moving on to the second question, "Residues, chemical outgases, and contaminated fluids are examples of this type of contamination." The provided examples suggest that the focus here is on contamination caused by molecular substances.

"Molecular" contamination refers to the presence of chemical compounds or substances in molecular form that can potentially affect the functioning of aerospace systems. This type of contamination can occur due to residues from manufacturing processes, outgassing of chemicals from materials, or the presence of contaminated fluids.

It's worth mentioning that contamination in the aerospace industry is a widespread concern, and different companies or organizations might have their own terminology or classification system for various types of contamination. Therefore, it's always important to refer to the specific guidelines or industry standards being followed when discussing contamination in the aerospace field.
