Aside from flammable gases, what other gas that may accumulate in potentially hazardous areas
Toxic Gases
The lowest temperature at which it can vaporise to form an ignitable mixture in air. Measuring it requires an ignition source.
Flash Point
Ballast water tank in a tanker which is completely separated from oil cargoes and fuel oil system and is permanently allocated to the carriage of ballast
Segregated Ballast Tanks
A colorless, odorless flammable gas that is the main constituent of natural gas. It is the simplest member of the alkane series of hydrocarbons.
Methane
An oily mixture of hydrocarbons that can be extracted from layers of rock and used to produce fuel
Petroleum
Two heaviest and least volatile components of gasoline, decane and dodecane, when mixed together becomes
Kerosene
Volatile is when at normal temperatures, a substance has
High Vapor
A common measure of the volatility of petroleum distillate fuels. It is defined as the equilibrium partial pressure exerted by a volatile organic liquid as a function of temperature as determined by the test method ASTM D 2879.
True Vapor Pressure
A relative measure of the tendency to evaporate (volatility), depends on the nature of the substance and ambient temperature, and reaches a state of equilibrium (where no more vapors escape from the substance) in closed spaces
Vapor Pressure
A system whereby oil tanks on a tanker are cleaned out between voyages not with water, but with crude oil - the cargo itself.
Crude Oil Washing
This guide makes recommendations for tanker and terminal personnel on the safe carriage and handling of crude oil and petroleum products on tankers and at terminals.
