An electrical storm can spell real trouble for a business of any size. Although direct lightning strikes do occasionally happen, the real threat is when lighting strikes somewhere along the power grid. This can cause dangerous surges along the trunk lines, which can overload and damage your electronics. In addition, these strikes can disable parts of the power grid for hours or even days, cutting power to your business. When putting together your emergency plan for electrical storms, see to surge protection, data backup and backup power.
