Plan and prepare
List the services you need during an outage before choosing backup equipment. Identify communications, lighting, refrigeration, and any medically necessary devices separately. Record each device's manufacturer requirements and the duration of support you need. Ask the care team and equipment supplier about medical-device continuity.
Discuss the list with a qualified installer, utility, or appropriate equipment provider. Ask what the proposed system can actually support, how it is maintained, and what happens when its stored energy or fuel is exhausted. A capacity label alone does not establish compatibility or dependable runtime.
Use a clear process
Include safe location and operation in the decision. CPSC says portable generators belong outdoors, at least 20 feet from homes, with exhaust directed away; never operate one in a house or garage. Follow all manufacturer requirements and arrange working carbon-monoxide alarms as recommended.
Leave building connections and wiring to qualified professionals using approved equipment and applicable requirements. Do not improvise a connection through a household outlet. Plan maintenance, permitted storage, and a fallback location if the equipment cannot be operated safely where you live.
Worked example
Suppose a household identifies a phone, a few lights, refrigeration, and a powered medical device as important during an outage. List the medical device separately and obtain its continuity requirements from the care team and supplier. For the remaining equipment, collect the manufacturer information a qualified provider needs to evaluate compatibility and expected support. Ask the provider to explain the assumptions behind any runtime estimate and which equipment can operate together. Do not assume that a product described as a whole-home or emergency solution meets every need in that particular household.
Decisions and exceptions
Create an options sheet that compares more than purchase price. Include supported functions, safe operating location, maintenance, authorized installation, storage requirements, recharge or resupply arrangements, and who can operate it. Record the alternative if the chosen option is unavailable. In some living arrangements, there may be no suitable place to operate a fuel-burning portable generator; the plan then needs another appropriate option or access to a verified support location. A device that cannot be used safely at the intended site should not be counted as dependable backup capacity.
Check and improve
Use a provider-approved rehearsal to check the whole arrangement. Confirm that the responsible person can find the instructions, identify the supported equipment, recognize limits, and follow the established procedure without improvising. Do not disconnect essential care or safety systems to create a realistic test. A community facility should document who is authorized to operate the system, how maintenance is recorded, and how users will be told when support is limited. After the exercise, record unresolved questions for the qualified provider. Review the plan when equipment, occupants, or building arrangements change, because an old assessment may no longer describe the actual loads and needs. Keep a practical route to help when safe operation or adequate support cannot be confirmed. Keep service contacts and the date of the latest professional assessment with the operating records so later reviewers can identify who confirmed the arrangement.
Solo and community application
Alone, begin with a plan for a few essential functions and a verified alternative place to obtain support. A community facility should assign trained operators, document supported loads, and coordinate with its responsible building and emergency-management staff.
Reference guidance
DOE's utility-disruption guidance and CPSC's safety guidance are the references; this is a planning worksheet, not installation instructions. Rehearse only within the approved operating procedure, document the observed limits, and revise the plan when essential devices or occupants' needs change.
