When Hurricane Laura roared ashore in August 2020, the wind sounded like a freight train, trees folded like lawn chairs, and the power grid took a beating. But one of the deadliest dangers did not arrive with a dramatic crash. It slipped silently through homes after the storm, invisible, odorless, and fast: carbon monoxide from portable generators.
That is the brutal lesson behind generator safety. A generator can keep your refrigerator cold, your phone charged, your medical equipment running, and your family from eating crackers by flashlight for three days straight. Used incorrectly, however, it can become more dangerous than the outage itself. After Hurricane Laura, Louisiana officials verified several storm-related deaths from carbon monoxide poisoning linked to generator use, a heartbreaking reminder that the “after” part of a hurricane can be just as dangerous as landfall.
This guide explains the generator safety tips every homeowner, renter, caregiver, and storm-season overthinker should know. The goal is simple: keep the lights on without turning your home into a carbon monoxide trap.
Why Hurricane Laura Changed the Generator Safety Conversation
Hurricane Laura made landfall near Cameron, Louisiana, as a powerful Category 4 hurricane. The storm brought extreme winds, catastrophic storm surge, inland damage, long power outages, and widespread disruption across southwest Louisiana and nearby areas. Many residents who survived the wind and flooding were then forced into days or weeks of recovery without reliable electricity.
That is when portable generators become tempting. They are loud, useful, and strangely comforting, like a mechanical rooster that runs on gasoline. But during major outages, generator mistakes happen quickly. People place units in garages, carports, sheds, porches, balconies, or too close to windows because they want to protect the machine from rain, theft, or flying debris. Unfortunately, those choices can allow carbon monoxide to enter living spaces.
Carbon monoxide, often shortened to CO, is produced when fuel burns. Gasoline-powered generators, propane generators, charcoal grills, camp stoves, vehicles, and small engines can all create it. The problem is that CO cannot be seen or smelled. There is no smoky warning, no dramatic villain music, and no “Hey, I’m dangerous” label floating in the air. People may feel headache, dizziness, nausea, weakness, chest pain, confusion, or flu-like symptoms, but by the time symptoms are obvious, the situation may already be urgent.
The Golden Rule: Never Run a Generator Indoors
If you remember only one generator safety tip, make it this: never use a portable generator indoors. Not in a house. Not in a garage. Not in a basement. Not in a crawl space. Not in a shed. Not in a “just for a few minutes” situation. “Just for a few minutes” is the exact phrase danger loves to hear.
Opening doors and windows does not make indoor generator use safe. Fans do not make it safe. A garage door halfway open does not make it safe. Carbon monoxide can build up rapidly in enclosed or partially enclosed spaces, and it can move into the home through doors, vents, cracks, attic spaces, and connected walls.
How Far Should a Generator Be From the House?
Place a portable generator outdoors at least 20 feet away from windows, doors, vents, crawl space openings, and any other path into the home. The exhaust should point away from the house and away from neighboring homes. Think of the exhaust like a rude guest: do not aim it at anyone’s living room.
The 20-foot rule matters because wind can push exhaust in unpredictable directions. A generator sitting right outside a window, under a porch roof, or near an open door can send CO indoors even though the unit is technically “outside.” Outside is not enough. Distance, direction, and airflow all matter.
Install Carbon Monoxide Alarms Before Storm Season
Carbon monoxide alarms are not optional storm accessories. They are life-safety equipment. Install battery-operated CO alarms or plug-in alarms with battery backup on every level of the home and outside sleeping areas. Interconnected alarms are even better because when one sounds, they all sound. That is annoying during a false alarm, but extremely useful when the alternative is sleeping through a real emergency.
Test alarms monthly. Replace batteries as recommended. Replace the entire alarm according to the manufacturer’s instructions. Many CO alarms do not last forever, even if they look perfectly fine sitting on the wall like a tiny plastic guardian angel.
What to Do If a CO Alarm Sounds
If a carbon monoxide alarm sounds, do not debate it, investigate it, or ask whether it is “probably just the battery.” Get everyone outside into fresh air immediately. Call 911 from outside. Do not go back in until emergency responders say it is safe. If anyone feels dizzy, weak, confused, nauseated, sleepy, or short of breath, treat it as urgent.
Do Not Backfeed Power Into Your Home
Backfeeding is the dangerous practice of plugging a generator into a wall outlet to power a home’s wiring. It may sound clever in the way a raccoon opening a trash can sounds clever, but it can be deadly. Backfeeding can energize power lines and create an electrocution risk for utility workers, neighbors, and anyone handling damaged electrical equipment.
If you want to connect a generator to your home’s electrical system, hire a qualified electrician to install a proper transfer switch or interlock system that meets local codes. Otherwise, plug appliances directly into the generator using heavy-duty, outdoor-rated extension cords that are rated for the load.
Use the Right Extension Cords
Choose three-pronged, grounded extension cords designed for outdoor use. Inspect cords before each use. If a cord is frayed, cracked, cut, warm to the touch, or looks like it survived a fight with a lawn mower, retire it. Do not overload cords, do not daisy-chain a collection of mystery cords, and do not run cords through standing water.
Match the cord rating to the wattage of what you plan to power. Refrigerators, freezers, window air conditioners, sump pumps, and medical devices can have higher starting watts than running watts. Translation: your appliance may demand a bigger power gulp when it starts than when it is humming along normally.
Keep the Generator Dry Without Trapping Exhaust
Generators and water are not friends. Using a generator in rain, flooding, or wet conditions can increase the risk of shock or electrocution. But covering it incorrectly can create a carbon monoxide or fire hazard. Do not throw a tarp over a running generator. That is not a shelter; that is a bad idea wearing a poncho.
Use a manufacturer-approved generator tent, canopy, or ventilated cover designed for safe operation. The setup must allow exhaust to escape freely, keep heat from building up, and protect electrical outlets from water. Keep the generator on a dry, stable surface and away from floodwater. Never touch the generator with wet hands or while standing in water.
Refuel Safely: Gasoline and Hot Engines Do Not Mix
Gasoline is useful, but it is also extremely flammable. Before refueling a generator, turn it off and let it cool. Spilling gasoline on a hot engine can cause a fire. This is one of those moments when patience is not merely a virtue; it is a fire-prevention strategy.
Store fuel in approved containers, away from living areas, ignition sources, water heaters, furnaces, grills, and anything that creates flame or heat. Keep fuel outside the home in a well-ventilated, secure area. Label containers clearly. Do not store gasoline in random bottles, milk jugs, or containers that could be mistaken for something else. Nobody needs a “mystery liquid” subplot during hurricane recovery.
Know What Your Generator Can Actually Power
One common mistake is treating a portable generator like a magic wall outlet with wheels. It is not. Every generator has limits. Overloading it can damage appliances, trip breakers, overheat cords, or create fire hazards.
Before storm season, make a power priority list. Start with essentials: medical equipment, refrigerator, freezer, phone charging, a fan, a few lights, and maybe a small window unit if the generator can handle it. Avoid trying to run the entire house unless you have a properly installed whole-home system designed for that load.
Start Smart and Load Gradually
Start the generator before connecting major appliances. Add loads one at a time. If the generator struggles, surges, or trips, reduce the load. Keep children and pets away from the unit, cords, fuel, and hot engine parts. A generator during a blackout can become the most interesting object in the yard, especially to curious kids. Treat it like a dangerous tool, not a backyard appliance pet.
Choose Safer Generator Technology When Possible
If you are shopping for a portable generator, look for models with carbon monoxide shutoff technology. These systems are designed to turn the generator off when dangerous CO levels are detected near the unit. Some newer standards also include reduced carbon monoxide emissions. These features do not replace safe placement, but they add an important layer of protection.
Also look for certification marks from recognized testing organizations. Read the owner’s manual before storm season, not during the storm while holding a flashlight in your teeth. Register the product if the manufacturer offers recall notifications. Maintain the generator according to the manual, including oil changes, air filters, spark plugs, and test runs.
Special Safety Tips for Apartments, Townhomes, and Dense Neighborhoods
Portable generators are especially risky in apartments and dense housing because safe placement may be impossible. Balconies, breezeways, hallways, stairwells, parking garages, and patios near doors or windows are not safe generator locations. Exhaust can travel into your unit or your neighbor’s unit.
If you live in an apartment, talk with property management before storm season about backup power rules and safe alternatives. Battery power stations, rechargeable fans, power banks, community cooling centers, and evacuation plans may be safer options than trying to operate a fuel-burning generator in a space that was never designed for one.
Generator Safety Checklist Before the Next Hurricane
- Place the generator outdoors, at least 20 feet from doors, windows, vents, and crawl space openings.
- Point exhaust away from your home and neighboring homes.
- Never run a generator indoors, in a garage, in a shed, on a porch, or on a balcony.
- Install CO alarms on every level and outside sleeping areas.
- Use grounded, outdoor-rated extension cords that match the load.
- Never plug a generator into a wall outlet.
- Use a transfer switch installed by a qualified electrician if connecting to home wiring.
- Turn off and cool the generator before refueling.
- Store gasoline in approved containers away from living spaces and heat sources.
- Keep the generator dry with a proper ventilated cover, not a tarp.
- Do not overload the generator.
- Read the manual before you need the machine.
Real-Life Lessons From Hurricane Laura and Generator Use
The most painful lesson from Hurricane Laura is that survival does not end when the wind stops. Many families did the hard part: they sheltered, evacuated, checked on relatives, cleared debris, and tried to recover. Then came heat, darkness, spoiled food, medical needs, and the understandable urge to get power back quickly. That is exactly when small decisions become life-or-death decisions.
Imagine a family returning home after a hurricane. The roof has damage, the refrigerator is warming, cell phones are almost dead, and everyone is exhausted. Someone rolls the generator near the garage because it feels safer from theft and rain. The garage door is open, so it seems reasonable. The extension cord reaches. The refrigerator hums. The family finally relaxes. But carbon monoxide begins moving where people cannot see it. By bedtime, symptoms may look like fatigue, stress, dehydration, or a headache from cleanup work. That is what makes CO so dangerous: it disguises itself as everything else.
Another common scenario involves a generator placed outside but too close to an open window. During hurricane recovery, windows may be open because air conditioning is out. Screens may be damaged. Doors may be propped open while people carry supplies in and out. Wind shifts. Exhaust drifts. A setup that seemed safe at noon can become hazardous at midnight.
The practical experience here is not complicated: plan the generator location before the storm. Measure 20 feet when the weather is calm. Buy a long enough generator cord in advance. Decide which appliances matter most. Install CO alarms before hurricane season. Store fuel properly before stores are closed and everyone in town is suddenly hunting for gas cans like they are rare museum artifacts.
Families should also assign generator responsibilities. One adult should know how to start it, stop it, refuel it, check oil, connect loads, and respond to alarms. A second adult should know the same things in case the first person is away or exhausted. Written instructions taped inside a plastic bag can help during stressful conditions. Storm recovery is not the ideal time to discover that the only person who understands the generator is asleep, unreachable, or “pretty sure the manual was in the box.”
Neighbors matter, too. After Hurricane Laura, entire communities were operating generators at once. Your generator exhaust can affect the house next door, especially in dense neighborhoods. Talk to neighbors about placement. If you hear a CO alarm, smell fuel, see unsafe cords in water, or notice a generator running in a garage, speak up. Safety may feel awkward for ten seconds, but silence can be tragic.
For older adults, people with disabilities, and families using powered medical equipment, generator planning is even more important. Consider backup batteries, a written emergency plan, medication cooling needs, and transportation options. Local emergency management offices may offer registries or resources for people who depend on electricity for medical devices. A generator can be part of that plan, but it should not be the entire plan.
Finally, do not let familiarity make you careless. Many generator accidents happen to people who have used one before. Experience is helpful, but routine can create shortcuts. Every time you run a generator, ask the same boring but lifesaving questions: Is it outside? Is it 20 feet away? Is exhaust pointed away? Are CO alarms working? Are cords rated and dry? Is fuel stored safely? Boring questions are excellent. In disasters, boring is underrated.
Conclusion: Power Is Helpful, But Safe Power Saves Lives
Portable generators are valuable tools during hurricanes, severe storms, and long outages. They can protect food, support medical needs, improve communication, and make recovery more bearable. But Hurricane Laura showed why generator safety tips must be treated as essential disaster preparation, not fine print.
Carbon monoxide poisoning is preventable. Electrical backfeeding is preventable. Refueling fires are preventable. Overload hazards are preventable. The key is to prepare before the outage, follow the 20-foot rule, install working CO alarms, use proper cords, avoid backfeeding, and treat every generator like a serious piece of equipment.
The storm may knock out your power. It should not take your peace, your home, or your family. Use the generator, respect the danger, and let the only thing dramatic after the hurricane be your neighbor’s story about fighting a patio umbrella in 80-mile-per-hour wind.
