What is essential for effective cleaning of parts in preparation for assembly?

Wearing appropriate personal protective equipment (PPE) is essential for the effective cleaning of parts in preparation for assembly because it ensures the safety of the worker during the cleaning process. Cleaning agents and solvents can often contain hazardous chemicals that may be harmful if they come into contact with skin, are inhaled, or are splashed into the eyes.

While other methods such as using hot water or solvents may help clean parts, the primary focus of effective cleaning starts with safety. Proper PPE, including gloves, goggles, and masks, provides a barrier against potential exposure to harmful substances, enabling the mechanic to handle parts and cleaning materials safely. This precaution not only protects the individual but also promotes a safe work environment, which is critical in aerospace assembly settings where cleanliness and safety directly impact the integrity and performance of the assembly.
