8. Describe a challenging lubrication issue you encountered and how you resolved it.

In a recent project, we faced an issue with premature bearing failure in a high-temperature application:

• Analysis and Investigation: I analyzed the failed bearing, lubricant properties, and operating conditions.
• Solution Identification: Determined that the lubricant’s viscosity was too low for the high temperatures, resulting in insufficient film thickness.
• Implementation: Recommended and implemented a lubricant with higher viscosity, suitable for the extreme temperature conditions.
• Monitoring and Evaluation: Monitored the bearing performance and confirmed reduced failure rates, validating the solution.

9. What safety precautions should be considered when working with lubricants?

Safety is paramount when handling lubricants:

• Material Safety Data Sheets (MSDS): Familiarizing myself with MSDSs to understand the potential hazards of lubricants.
• Personal Protective Equipment (PPE): Utilizing appropriate PPE, such as gloves, eye protection, and respirators, to minimize exposure.
• Proper Handling and Storage: Adhering to safe handling and storage practices to prevent spills, contamination, and fire hazards.
• Waste Disposal: Ensuring proper disposal of used lubricants and contaminated materials to minimize environmental impact.

10. How do you contribute to environmental sustainability in your role as a Lubricating Specialist?

Environmental sustainability is integral to my role:

• Lubricant Selection: Prioritizing bio-based and environmentally friendly lubricants to reduce environmental impact.
• Lubricant Management: Implementing programs to optimize lubricant usage, minimize waste, and extend lubricant life.
• Collaboration with Suppliers: Working with suppliers to explore and adopt sustainable lubricant solutions.
• Awareness and Training: Educating colleagues and customers on the importance of environmental sustainability in lubrication practices.
