When power outages strike, whether due to severe weather, grid failures, or equipment issues a portable backup generator can be a lifesaver. However, portable generators also pose serious safety risks if used improperly. At Elios, we’re committed to helping Texas families power their homes safely and reliably. Here’s everything you need to know about portable generator safety, so you can enjoy backup power without putting your household at risk.

1. Never Run Your Portable Backup Generator Indoors

Carbon Monoxide Danger

Portable generators emit deadly carbon monoxide (CO) gas. CO is colorless, odorless, and can accumulate quickly in enclosed spaces, leading to poisoning or even death. Always operate your generator:

Outdoors and at least 20 feet away from doors, windows, and vents
On a level surface, away from flammable materials
Under a canopy or open shelter (but never fully enclosed) to protect it from rain

Installing a battery backup or professional standby generator with proper ventilation is the safest long-term solution. Ask Elios how we can integrate these options into your home.

2. Protect Against Electrical Hazards

Proper Connection Methods

Improper wiring can backfeed electricity into utility lines, endangering utility workers and damaging equipment. To avoid shocks and fires:

Use a transfer switch: This isolating device prevents backfeed and allows safe power routing from your generator to your home circuits.
Employ heavy-duty cords: Only use generator-rated, appliance-heavy extension cords that are in good condition, labeled for outdoor use, and free of cuts or frays.
Match wattage: Never overload your generator. Calculate the starting and running wattage of essential appliances (refrigerator, sump pump, lights) and ensure your generator’s rated capacity exceeds that total by 10–20%.

Elios-certified electricians can install a transfer switch and professionally wire your generator for worry-free operation.

3. Store and Handle Fuel Safely

Gasoline & Diesel Precautions

Fueling errors cause many generator fires and spills. Follow these guidelines:

Cool down first: Always let your generator engine cool for at least 15–20 minutes before refueling to prevent igniting hot components.
Use approved containers: Store gasoline or diesel in UL-listed, tightly sealed containers away from your home and any open flames.
Maintain ventilation: Fill fuel cans outdoors and wipe up any spills immediately.

For extended outages, consider an LP-powered standby generator that taps directly into your home’s propane tank with no refueling required during the storm.

4. Maintain a Safe Placement

Ideal Generator Location

Where you place your portable generator affects everything from exhaust dispersion to noise levels:

Solid, flat surface: Concrete or gravel pad minimizes vibration and reduces the chance of fuel spills.
Clearance: Maintain at least 3 feet of clearance around all sides to ensure airflow and access for maintenance.
Distance from living areas: Position the generator downwind so exhaust moves away from your home.

Elios can recommend generator shelters or custom pads to optimize your generator’s placement and protection.

5. Perform Regular Maintenance Checks

Keep Your Generator Ready

Generators that haven’t been exercised or serviced can fail when you need them most. Implement a simple maintenance routine:

Monthly test run: Run the generator under load for 15–20 minutes to circulate oil and verify performance.
Oil & filter changes: Follow the manufacturer’s schedule (typically every 50–100 hours).
Air filter inspection: Clean or replace filters to prevent overheating and ensure fuel efficiency.
Spark plug & battery checks: Confirm spark plugs are clean and batteries fully charged, especially before storm season.

If you’d rather leave maintenance to the pros, ask about Elios’s annual service plans that cover oil changes, inspections, and testing.

6. Practice Safe Load Management

Prioritize Critical Circuits

Portable generators have limited capacity. To manage loads effectively:

List essentials: Refrigerator, freezer, sump pump, lights, and communication devices.
Start larger motors first: Always power refrigerators or pumps before running lighting or electronics.
Rotate loads if needed: Turn off non-essential circuits when adding a new appliance to avoid overloading.

For whole-home coverage without juggling loads, a stationary standby generator sized and installed by Elios delivers seamless, automatic backup.

7. Plan Your Emergency Response

Beyond the Generator

A robust outage plan goes beyond backup power:

Assemble an emergency kit: Flashlights, batteries, bottled water, non-perishable food, first-aid supplies, and a battery-powered radio.
Keep emergency contacts handy: Post phone numbers for utilities, medical services, and Elios support.
Develop a family plan: Choose a meeting spot, designate a power manager (who controls the generator), and review basic safety steps annually.
