This cement acts as a fire barrier to protect the equipment from overheating, failing, and potentially causing a fire to spread and do more damage. In the case of storage sphere legs or tower skirts, fireproofing may prevent the metal from buckling and distorting. Fireproofing is vital because the consequences of a fire are so severe.
