Lubricants Function

reduce friction, cooling & surface abrasion (wear) between moving parts.

Synthetic used in

modern jet engines

Synthetic oil with long skin contacts can cause

dermatitis

Flash point

is the lowest temperature which fluid can be ignitable mixture with air

Viscosity

is the measure of fluid resistance to flow.

Desirable viscosity

low enough for easier starting at low temperatures and high enough to keep lubrication at high temperatures

Contaminated oil with water appears

globules or misty.

When the oil contaminate with kerosene the main effect is possible

breakdown of seal within the lubricant system

Engine oil detergent additives used to

allow the oil to hold sludge or debris in suspension to prevent its buildup within the engine

As general guide line procedure for oil fluid contamination

take oil sample clean or replace oil filter and flush system with clean lubricating oil

Kerosene based fuel used in gas turbine engine because it has

high heat energy per gallon and lubricate fuel system components.

When working in fuel tanks keep

using an air-fed vapour mask all the time
