A UPS, or Uninterruptible Power Supply, is the ideal device for preventing harmful restarts during short power outages because it provides emergency power to connected devices when the main power source fails. This ability to supply power instantly allows devices to continue operating without interruption, which is especially critical for computers and other sensitive electronics that require a consistent power supply to avoid data loss or hardware damage.

In addition to providing backup power, a UPS often includes features such as surge protection and power conditioning. This contrasts with devices like surge protectors, which primarily shield against voltage spikes, and line conditioners, which can stabilize voltage but do not offer battery backup. An MSDS (Material Safety Data Sheet) is unrelated to power supply solutions, as it pertains to the handling of hazardous materials. Therefore, a UPS is the comprehensive solution for safeguarding against the adverse effects of power outages.
