Healthcare Industry and the Risk of Power Outages


Hospitals and medical facilities are the communities’ life support system and a system in which we cannot afford a power outage. When brownouts or severe weather strikes, vital power is still needed to keep monitors, oxygen pumps, dialysis and other valuable equipment working in order to sustain human life. When the power is out, a hospital or medical facility must use a backup generator to ensure that everything stays up and running.

The need for generators in the healthcare market is undeniable and of the upmost importance. Here at Ultimate Service Associates we work to keep those generators in top condition and ready to work when the lights go out.
