Which of the following is NOT considered a service debris contamination source?

Service debris contamination refers to unwanted materials or particles that can negatively impact the performance and reliability of equipment. Understanding the sources of contamination is key to maintaining asset integrity and ensuring optimal operation.

Wear particles, sealing materials, and fluid residues are all aspects of service debris contamination.

Wear particles originate from the friction and interaction of moving parts within machinery. Over time, these particles are generated through normal operations and can accumulate within a system, potentially leading to increased wear and failure if not managed.

Sealing materials can break down over time due to exposure to chemicals and physical stress. Pieces of seals or gaskets can enter the fluid system, contributing to contamination and potentially causing issues such as leaks or inefficient sealing.

Fluid residues, which can include remnants of oils, lubricants, or other operational fluids, may also accumulate within a system. These residues can alter the chemical makeup of the operating fluid, degrade performance, and promote further contamination.

In contrast, process chemicals are typically necessary for the function of an operation and are not inherently considered a source of contamination. While they can potentially contribute to contamination under certain circumstances (like improper use or unintentional mixing), their primary purpose is functional within the manufacturing or processing environment. Thus, they do not fit the definition of
