CLS CLS Lubricant Storage, Handling & Contamination Control

Question 1

What is the recommended maximum storage temperature for most mineral-based lubricants to prevent accelerated oxidation?

Accepted Answer

Below 40°C (104°F)

Answer

Storing lubricants below 40°C prevents thermal stress that accelerates oxidation and additive degradation in storage.

Question 2

The best practice for outdoor drum storage is to position horizontal drums with the bungs at which orientation?

Accepted Answer

3 o'clock and 9 o'clock (horizontal, side bungs submerged)

Answer

Positioning bungs at the 3 and 9 o'clock positions keeps them submerged in oil, preventing moisture ingress through the seals during temperature cycling.

Question 3

Which contamination control device is recommended on lubricant storage tank vent lines to prevent particulate and moisture ingress?

Accepted Answer

Desiccant breather

Answer

Desiccant breathers filter particulates and absorb moisture from air entering storage tanks during thermal breathing cycles.

Question 4

What is the primary reason dedicated, color-coded dispensing equipment is recommended in lubrication programs?

Accepted Answer

To prevent cross-contamination between different lubricant types

Answer

Color-coded equipment ensures each lubricant has dedicated dispensing tools, preventing inadvertent mixing of incompatible products.

Question 5

According to best lubrication practices, what is the maximum recommended shelf life for a lithium complex grease stored under ideal conditions?

Accepted Answer

2 years

Answer

Most lubricating greases, including lithium complex, have a recommended shelf life of approximately 2 years when stored correctly.
