Most Common Generator Accidents Reported After Storms

Many generator-related accidents share the same causes.

Common incidents include:

• Carbon monoxide poisoning from indoor generator use

• Electrical shock caused by wet operating conditions

• Fires resulting from improper fuel storage

• Burns caused by refueling hot generators

• Backfeeding electricity into utility lines

• Equipment failures caused by overloaded generators

The good news is that most of these accidents are preventable. Following proven safety guidelines and using properly installed equipment can greatly reduce the likelihood of injury or property damage during a power outage.

Understanding the Biggest Generator Hazards

Generators are designed to provide temporary power during outages. While they are useful, they can also create serious dangers when used incorrectly. Understanding these hazards is the first step toward preventing accidents and keeping your property safe.

Carbon Monoxide Poisoning

Carbon monoxide is one of the most dangerous generator-related hazards. This gas is produced whenever fuel burns. Because it is colorless and odorless, people often do not realize they are being exposed until symptoms appear.

A generator should never be operated inside a home, garage, shed, basement, crawl space, or any partially enclosed area. Even if windows or doors are open, carbon monoxide can build up quickly and spread indoors.

Common symptoms of carbon monoxide poisoning include:

• Headache

• Dizziness

• Nausea

• Weakness

• Confusion

• Vomiting

• Loss of consciousness

If anyone experiences these symptoms while a generator is running, move them to fresh air immediately and seek emergency medical attention.

Installing carbon monoxide detectors throughout your home or facility adds another layer of protection. Test them regularly and replace batteries as recommended by the manufacturer.

Electrical Shock and Electrocution

Generators produce electricity, which means improper use can result in severe shock or electrocution. One of the most common causes of electrical injury occurs when generators are used in wet conditions. Water increases the risk of electricity traveling through unintended paths, creating dangerous situations for anyone nearby.

To reduce electrical hazards:

• Place generators on dry, level surfaces.

• Keep them away from standing water.

• Use outdoor-rated extension cords.

• Inspect cords before every use.

• Avoid touching electrical equipment with wet hands.

If severe weather is expected, consider a properly designed generator cover that allows ventilation while protecting the equipment from rain.

Fire and Explosion Risks

Generators use gasoline, diesel, propane, or natural gas. All of these fuel sources require careful handling. Fuel spills near hot engine components can ignite quickly. Improper storage also increases the risk of fire.

Follow these fuel safety practices:

• Store fuel in approved containers.

• Keep fuel away from living spaces.

• Never smoke while refueling.

• Clean up spills immediately.

• Keep combustible materials away from the generator.

Many generator fires occur because fuel containers are stored too close to operating equipment. Maintaining adequate clearance around the unit helps prevent these incidents.

Generator Overload Damage

Every generator has a maximum power capacity. When too many appliances or systems are connected at once, the generator can become overloaded.

An overloaded generator may:

Before an outage occurs, calculate the power requirements of critical devices you plan to run. Prioritize essential equipment and avoid connecting unnecessary loads. For larger homes and commercial buildings, professional load calculations help ensure the generator is properly sized for the application.

Backfeeding Utility Lines

Backfeeding occurs when generator power flows backward through a building’s electrical system and into utility lines. This situation creates a serious danger for utility crews working to restore power. A line believed to be de-energized may still carry electricity from a generator. Backfeeding can also damage electrical equipment and create code violations.

The safest way to prevent backfeeding is through a properly installed transfer switch. These devices isolate the generator from the utility grid and ensure power flows only where it should.

Generator Safety Tips Before a Power Outage

Generator Safety Tips During Power Outages

When the power goes out, it is tempting to focus on getting electricity restored as quickly as possible. However, generator safety should remain the top priority. Most generator-related accidents occur during active outages when people rush through setup or overlook important precautions. Following proper operating procedures helps protect your family, employees, property, and equipment.

Place the Generator in the Correct Location

Proper placement is one of the most important generator safety tips. A portable generator should always be operated outdoors in a well-ventilated area. Keep the unit at least 20 feet away from doors, windows, vents, crawl space openings, and attached garages.

Generator exhaust contains carbon monoxide, which can enter buildings even when doors or windows appear closed. Position the exhaust so it points away from occupied areas whenever possible.

Never place a generator:

• Inside a home

• Inside a garage

• Under open windows

• In a basement

• In a shed

• In a crawl space

• Near air intake vents

Following the 20-foot rule greatly reduces the risk of carbon monoxide exposure.

Keep Generators Dry

Water and electricity create a dangerous combination. Generators should be operated on a dry, stable surface. Standing water, wet grass, and flooded areas increase the risk of electrical shock. If rain is expected, use a manufacturer-approved cover or open canopy structure designed for generator use. The cover must allow proper ventilation while protecting the equipment from direct rainfall.

Avoid:

• Operating generators during heavy rain without protection

• Handling electrical cords with wet hands

• Placing generators in puddles or flooded areas

A dry operating environment helps improve both safety and equipment reliability.

Never Operate a Generator Indoors

Many carbon monoxide incidents occur because people believe a partially enclosed space is safe. It is not.

Opening a garage door or window does not provide enough ventilation to prevent carbon monoxide buildup. The gas can spread rapidly and enter nearby living spaces. Safe generator operation always means operating outdoors and away from occupied buildings.

If severe weather makes outdoor operation difficult, consider investing in a professionally installed standby generator system designed for long-term use.

Use Heavy-Duty Outdoor-Rated Extension Cords

Extension cords play an important role during power outages. Using the wrong cord can lead to overheating, equipment damage, or fire.

Choose extension cords that are:

• Rated for outdoor use

• Free from cuts or damage

• Equipped with grounding prongs

• Sized for the electrical load

Inspect cords before every use. Replace damaged cords immediately rather than attempting temporary repairs.

Avoid Overloading the Generator

Every generator has operating limits. Connecting too many appliances at once can overload the system and reduce performance.

Common signs of overloading include:

• Tripped breakers

• Flickering lights

• Voltage fluctuations

• Engine strain

• Unexpected shutdowns

Focus on powering essential equipment first.

Typical priority loads include:

• Refrigerators

• Freezers

• Medical equipment

• Sump pumps

• Communication devices

• Security systems

Commercial properties should identify critical systems before an outage occurs and establish a power priority plan.

Prioritize Essential Appliances

Not every device needs backup power. Attempting to run everything at once often creates unnecessary strain on the generator. A practical approach is to divide loads into three categories:

This approach helps maximize runtime while reducing overload risks.

Monitor Fuel Levels Safely

Running out of fuel during operation can interrupt power to important equipment. Monitor fuel levels regularly, especially during extended outages. However, never attempt to add fuel while the generator is running.

Always:

• Turn off the generator

• Allow it to cool completely

• Move fuel containers away from ignition sources

• Refuel carefully to avoid spills

A few extra minutes of caution can prevent serious accidents.

Keep Children and Pets Away

Generators become extremely hot during operation. Moving parts, electrical connections, and hot exhaust components can cause injuries if touched. Establish a safety zone around the generator and keep children and pets away at all times. For businesses and commercial properties, restrict access to generator areas and post safety signage when appropriate.

Watch for Warning Signs of Malfunction

Generators often provide early signs when something is wrong.

Pay attention to:

• Appliances

• Generators

• Utility equipment

A properly installed transfer switch helps prevent backfeeding and is considered one of the most important generator safety devices.

Do I need a transfer switch for a generator?

A transfer switch is strongly recommended and is often required when connecting a generator to a building’s electrical system.

The transfer switch safely isolates generator power from utility power and helps prevent dangerous backfeeding.

Benefits include:

• Improved safety

• Easier operation

• Better code compliance

• Protection for electrical equipment

For standby generators, transfer switches are typically a standard part of the installation.

How often should a generator be serviced?

Maintenance schedules vary depending on the generator manufacturer and operating conditions.

Most generators should be inspected at least once a year. Units that operate frequently may require more frequent service.

Common maintenance tasks include:

• Oil changes

• Battery inspections

• Air filter replacement

• Fuel system inspections

• Cooling system checks

Routine maintenance helps improve reliability and reduces the risk of unexpected failures during an outage.

What appliances should I power first during an outage?

Focus on essential equipment before connecting optional loads.

Priority items often include:

• Refrigerators

• Freezers

• Medical devices

• Sump pumps

• Security systems

• Communication equipment

After essential loads are connected, additional equipment can be added if the generator has sufficient capacity. Avoid overloading the generator by attempting to power everything at once.

Can a portable generator power an entire home?

Most portable generators cannot power an entire home, especially larger residences with central air conditioning and multiple major appliances.

Portable units are generally intended to support selected circuits or essential appliances.

A whole-home standby generator is usually the better option for complete backup power coverage. A licensed electrician can perform load calculations to determine the appropriate generator size for your needs.

How long can a generator run continuously?

Runtime depends on the generator type, fuel supply, load demand, and manufacturer specifications.

Many portable generators can operate for 8 to 12 hours on a full tank under moderate loads. Standby generators connected to natural gas or large propane supplies can often operate much longer.

Periodic inspections during operation are important. Check fuel levels, monitor performance, and follow maintenance recommendations during extended outages.

What type of extension cord should I use with a generator?

Only use heavy-duty extension cords rated for outdoor use and designed to handle the generator’s electrical output.

A suitable extension cord should:

• Include a grounding prong

• Be free from cuts or damage

• Match the intended load

• Be rated for outdoor environments

Undersized or damaged cords can overheat and create fire hazards.

Is a standby generator safer than a portable generator?

In many situations, yes.

Standby generators are permanently installed and typically include automatic transfer switches. This reduces the likelihood of user error and eliminates many of the risks associated with manual setup.

They also reduce the need for extension cords and often use permanent fuel supplies such as natural gas or propane.

However, regular maintenance and professional installation remain essential for safe operation.

How much fuel should I store for emergency power?

The amount depends on generator size, expected runtime, and local regulations.

Property owners should store enough fuel to support anticipated outages while following all safety requirements.

Keep fuel:

• In approved containers

• Away from living spaces

• Away from ignition sources

• In cool, dry locations

Businesses may require larger fuel reserves and should establish documented fuel management procedures.

When should I replace an older generator?

Replacement may be worth considering if the generator:

• Experiences frequent breakdowns

• Struggles to start

• No longer meets power demands

• Has major component failures

• Lacks modern safety features

A professional inspection can help determine whether repairs or replacement provide the better long-term value.

Should businesses have generator maintenance contracts?

Yes. Maintenance contracts help ensure backup power systems receive regular inspections and service.

A typical maintenance program may include:

• Scheduled testing

• Oil and filter changes

• Battery inspections

• Fuel system evaluations

• Transfer switch inspections

Routine maintenance reduces the likelihood of unexpected failures and helps businesses maintain reliable backup power during emergencies.
