What precautions should be taken for storage of cement?

Packed Cement must be stored in a safe and stable manner, in unopened bags, clear of the ground, in cool dry conditions and protected from excessive draught. Bulk Cement must be stored in silos that are waterproof, clean and protected from contamination, dry (internal condensation minimised) with stock rotated in chronological order of the despatch dates marked on delivery documents. To prevent burial or suffocation, do not enter a confined space, such as a silo, bin, bulk truck or other storage container or vessel that stores or contains cement without taking the proper safety measures. Cement can buildup or adhere to the walls of a confined space. The cement can release, collapse or fall unexpectedly.
