Handling & Storage of Lime :
Lime in its raw or unhydrated form requires careful handling to avoid accident and losses.
A) Quick Lime :
Quick Lime should be protected from water while handling for transport or during storage.It will start getting hydrated with evolution of heat that can cause burn injuries of very serious nature.
When lime stoared in wooden barrels comes in contact with water , so much heat may be evolved as to burn the barrels and also the store house or the trucks or wagons in which it is being transported.
B) fat Lime :
Fat lime must be protected from direct contact with atmosphere moisture & carbon dioxide. Uncovered lime gets air-slaked,that is, gets slowly hydrated by absorbing moisture from the atmosphere.
Such slacked-lime then combines with atmospheric carbon dioxide and starts setting.
It gets converted to a useless hard material which is lift with very little or no binding properties
However,stored temporarily for some time b y pilling it up into a compact heap which is covered with a thick layer of lime dust.This dust saves the main heap from the attack of moist air.
C) Hydraulic Lime :
It safer in transport & can be stored for longer periods as compared to fat lime. It must be treated as a lime & not as a cement & same precautions taken while working with it.
