Machines serve as the backbone of all industrial businesses. If anything goes wrong with these machines, business operations will be at a standstill. MB covers the sudden and unforeseen damage to machinery, plant or equipment whilst at work or rest, during clearing, maintenance, overhauling, inspection, or while being transported within the premises. This insurance does not cover any foreseeable gradual damage or loss to the machines. Moreover, deterioration of stock is available as an ancillary cover with MB.
