Oilers/Plant Tenders (HHC) Civil Service Practice Exam

In a lubricating oil storage facility, how is lubricating oil NOT normally removed from large drums?

1. Pumping from the Bottom

2. Siphoning out of the Top of the Drum

3. Gravity Drainage

4. Using a tap or spigot

The correct answer is: Siphoning out of the Top of the Drum

In a lubricating oil storage facility, the process of removing oil from large drums typically relies on methods that ensure safety, efficiency, and proper handling of the product. Siphoning out of the top of the drum is generally not a standard practice. This is mainly due to the challenges it presents in controlling the flow of the viscous liquid, maintaining safety standards, and the potential for contamination and spilling. Pumping from the bottom, gravity drainage, and using a tap or spigot are all accepted methods for oil removal. These techniques allow for better management of the oil flow and help to minimize the risk of spills or exposure to air, which can lead to degradation of the lubricating oil. Each of these methods provides a reliable means of dispensing oil in a controlled manner, which is crucial in a facility that requires precise handling of lubricants.
