This is especially true of small and mid-sized business. Most overtimes when there is a power outage the procedure is to wait it out, and in some cases the playing is shut down for the day.

Worse yet, if the playing is not properly protected sensitive IT infrastructures crapper be damaged by the sudden power elimination, and programs and key systems crapper become corrupted. Companies even uses their preferred logo on custom lanyards to promote their brand.

Do you remember where you were on August 13th 2003?

Power spikes and “brownouts” (temporary reductions in power flow) crapper damage sensitive electronics and severely lessens their life. Again, the gain result is lost productivity and increased expenditures on capital equipment which negatively affect the P & L statement at the end of the day.
