Carbon monoxide (CO) is an odorless, invisible gas that is so toxic it can kill a person after only a few minutes of concentrated exposure. Gas-powered, portable generators produce carbon monoxide in sufficient quantities to poison and kill consumers who may misuse the device while not fully understanding the risk. Although manufacturers have implemented safety measures designed to reduce the incidence of CO poisoning, consumer protection advocates say they do not go far enough and want stricter safety standards imposed.  

The Frequency of Carbon Monoxide Poisoning

People are exposed to low doses of carbon monoxide all the time. Carbon monoxide is in the air we breathe in varying concentrations. CO is a byproduct of the burning of carbon-based fuels. As long as the ventilation is adequate CO is not able to accumulate in amounts sufficiently concentrated to be critically harmful. But when fuel-burning appliances do not have proper ventilation, concentrations of CO can build up and quickly become deadly. 

According to the Centers for Disease Control and Prevention (CDC), emergency rooms treat about 20,000 people each year in the United States for carbon monoxide poisoning, and close to 500 people die after CO exposure. Carbon monoxide poisoning is the leading cause of death by poisoning.

Symptoms of Carbon Monoxide Exposure

Exposure to carbon monoxide can result in a variety of symptoms depending on the CO concentration levels. The Consumer Product Safety Commission (CPSC) says the symptoms of low-level carbon monoxide exposure can mimic the flu without the fever. 

  • Headache
  • Fatigue
  • Nausea
  • Dizziness
  • Shortness of breath
  • Blurred vision

As CO concentration levels increase, symptoms become more severe:

  • Confusion
  • Vomiting
  • Chest pain
  • Heart failure
  • Seizures
  • Loss of Consciousness/Coma
  • Death

Common Exposures to Carbon Monoxide

People are exposed to small amounts of carbon monoxide from instruments and appliances used in everyday living. Vehicles that burn fossil fuels emit CO, but the primary risk for carbon monoxide poisoning comes from the operation of gas generators used as auxiliary power sources and fuel-burning appliances used to generate heat. 

Power Outages and Generator Use in Louisiana

Power outages are an anticipated occurrence during hurricane season in Louisiana. Generators can provide auxiliary power for homes and businesses that may experience long blackout periods. Each time there is increased use of gas-powered generators, the number of carbon monoxide poisoning incidents also increases.

In 2020, there were 15 deaths associated with Hurricane Laura. The majority of the deaths occurred from carbon monoxide poisoning due to the improper use of a generator. Five people in one household were fatally poisoned by CO from a generator that was running inside an attached garage. 

In 2021, 81 Louisiana residents died of carbon monoxide poisoning, and hundreds were sent to area hospitals, according to the Louisiana Department of Health (LDH). LDH advises those who use generators to observe the following safety guidelines to avoid accidental CO poisoning:

  • Locate a generator at least 20 feet away from a home.
  • Close off any air entry points to the home near the generator.
  • Install a CO alarm
  • Turn generators off periodically to allow potential concentrations of gas to dissipate.
  • When the generator is off, ventilate the home by opening windows and doors.

Problems with Automatic Shut Off Switches on Generators

In response to safety concerns, manufacturers of portable generators have developed technology to help reduce the risk of carbon monoxide poisoning. One innovation is a CO monitoring device that is programmed to shut off a portable generator if dangerous concentrations of carbon monoxide are detected within the operating area of the generator. 

Manufacturers selling portable generators equipped with the shut-off feature have claimed it would prevent 99% of consumer deaths by carbon monoxide poisoning. But reality has shown those claims may not provide the safety consumers are expecting.

In the wake of Hurricane Ida in September of 2021, a Louisiana family succumbed to carbon monoxide poisoning when the shut-off switch on their brand-new generator failed to turn the machine off. The generator had been placed outside the family’s back door to power indoor appliances overnight. When emergency responders discovered the family the following morning, the generator was out of fuel, and the power switch was in the ‘on’ position.

The problem, according to an investigation done by the CPSC, was that the generator was outside the home, and its CO detection mechanism could not measure the build-up of carbon monoxide inside the home. The CPSC concluded the switch shut-off technology could not be relied on to prevent CO poisoning under all circumstances. 

Federal Laws May Soon Hold Portable Generator Manufacturers to Higher Safety Standards

The CPSC has been in favor of mandatory rules requiring generator manufacturers to create machines that expel less carbon monoxide. The holdup has been the federal laws giving the first crack at resolving the problem to the manufacturers themselves. Manufacturers have now had several years to create and implement an industry solution. 

After its conclusions about the effectiveness of the shut-off sensor, the CPSC determined that manufacturers have not voluntarily done enough to prevent carbon monoxide poisoning from gas-powered generators. The agency plans to recommend the adoption of laws requiring all manufacturers to meet specific safety standards. 

Product Liability Laws in Louisiana

Product Liability Attorney

When people are injured by products while using them in a way that could be reasonably anticipated by the manufacturer, they may have a product liability claim. In Louisiana, if something about a product makes it ‘unreasonably dangerous,’ the manufacturer of the product may be liable to an injured consumer. 

Under the Louisiana Product Liability Act, a product is considered unreasonably dangerous only in the following circumstances – the product is unreasonably dangerous:

  • In construction or composition by materially deviating from the manufacturer’s specifications or performance standards.
  • In design because there was a feasible alternative design capable of preventing consumer injury without undue burden on the manufacturer.
  • For failure to provide adequate warning of a characteristic that could cause damage.
  • For failing to conform to an express warranty when the failure is the cause of the damage.

Whether a manufacturer of a portable generator can be liable for carbon monoxide poisoning may depend on the specific circumstances leading to consumer injury or death. Product liability cases can involve complex issues that require specific legal knowledge and experience to evaluate and resolve successfully.
